The Relationship Between a Galaxy and its Black-Hole-Heart? 'It's Complicated.'
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a surprising connection between a supermassive black hole and the galaxy where it resides.Powerful radio jets from the black hole – which normally suppress star formation – are stimulating the production of cold gas in the galaxy's extended halo of hot gas. This newly identified supply of cold, dense gas could eventually fuel future star birth as well as feed the black hole itself.Read more (https://public.nrao.edu/news/pressreleases/2017-alma-phoenix).Credit: NRAO/AUI/NSF.Written and Narrated by Charles Blue (NRAO/AUI/NSF).

Comets Reveal Mystery Exoplanets Hiding in a Toxic Cloud
An international team of astronomers exploring the disk of gas and dust the bright star Beta Pictoris have uncovered a compact cloud of poisonous gas formed by ongoing rapid-fire collisions among a swarm of icy, comet-like bodies. The researchers suggest the comet swarm may be frozen debris trapped and concentrated by the gravity of an as-yet-unseen planet.

ALMA Sounds is a meeting point between radio astronomy captured by the Atacama Large Millimeter/submillimeter Array (ALMA) and musical creations made from observations taken from the most important radio telescope in the world. It arose from the recurring curiosity of artists and astronomers to understand and transcend the Universe. The project came to life with the arrival of the Sonar+D music and innovation festival to Chile: the perfect environment for astronomers and musicians to seek out a common language. The festival organizers proposed the project to ALMA and together they gave the initial impetus to the idea. It wasn’t an easy task. The waves captured by ALMA are completely different than the raw material musicians usually work with. ALMA Sounds is an initiative that seeks to interpret and decode the frequencies of the Universe, transforming them into sounds that can then be used by artists around the world to compose, share and create a community united around a search that has captivated humans for thousands of years.
Methanol around the young star TW Hydrae
This artist’s impression video shows the molecule methanol, or methyl alcohol (CH3OH). This organic compound has been found by the Atacama Large Millimeter/Submillimeter Array (ALMA) in the closest known protoplanetary disc, around the star TW Hydrae in the huge constellation of Hydra (The Female Watersnake). This is the first such detection of the compound in a young planet-forming disc. Its detection helps astronomers understand the chemical processes that occur during the formation of planetary systems and that ultimately lead to the creation of the ingredients for life.More information and download options: http://www.eso.org/public/videos/eso1619b/Credit:
Scientists Discover New Planets Forming In Distant Solar System
Scientists in Chile have discovered a new, earth-like planet forming in orbit of a star very much like our own sun called TW Hydrae.
Scientists believe that planets are formed from disks of debris that circle stars. Sometimes that debris coalesces into planets, creating a gap in the planetary disk which can be a tell-tale sign of a planet in the early stages of formation.
David Wilner, a co-author of the study said in a statement, "TW Hydrae is quite special. It is the nearest known protoplanetary disk to Earth and it may closely resemble our Solar System when it was only 10 million years old."
There may also be two more planets forming. The Scientists also found gaps in the disk which mirror the orbits of Uranus and Pluto in our solar system.
By studying this distant solar system, scientists may be able to help piece together the history of our own solar system and how it fits into the context of the universe as a whole.

Using ALMA, astronomers have taken a new, detailed look at the very early stages of planet formation around a binary star. Embedded in the outer reaches of a double star's protoplanetary disk, the researchers discovered a striking crescent-shape region of dust that is conspicuously devoid of gas. Astronomers struggle to understand how planets form in binary star systems. Early models suggested that the gravitational tug-of-war between two stellar bodies would send young planets into eccentric orbits, possibly ejecting them completely from their home system or sending them crashing into their stars. Observational evidence, however, reveals that planets do indeed form and maintain surprisingly stable orbits around double stars. To better understand how such systems form and evolve, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a new, detailed look at the planet-forming disk around HD 142527, a binary star about 450 light-years from Earth in a cluster of young stars known as the Scorpius-Centaurus Association. The HD 142527 system consists of a main star a little more than twice the mass of our Sun and a smaller companion star only about a third the mass of our Sun. They are separated by approximately one billion miles: a little more than the distance from the Sun to Saturn. Previous ALMA studies of this system revealed surprising details about the structure of the system's inner and outer disks. ( https://youtu.be/sRQcNdn2Lgw ) Planets form out of the expansive disks of dust and gas that surround young stars. Small dust grains and pockets of gas eventually come together under gravity, forming larger and larger agglomerations and eventually asteroids and planets. The fine points of this process are not well understood, however. By studying a wide range of protoplanetary disks with ALMA, astronomers hope to better understand the conditions that set the stage for planet formation across the Universe. ALMA's new, high-resolution images of HD 142527 show a broad elliptical ring around the double star. The disk begins incredibly far from the central star — about 50 times the Sun-Earth distance. Most of it consists of gases, including two forms of carbon monoxide (13CO and C180), but there is a noticeable dearth of gases within a huge arc of dust that extends nearly a third of the way around the star system. This crescent-shaped dust cloud may be the result of gravitational forces unique to binary stars and may also be the key to the formation of planets. Its lack of free-floating gases is likely the result of them freezing out and forming a thin layer of ice on the dust grains.
A Telescope So Powerful It Can See Into the Past

The observations were conducted over the course of four hours, when Juno was approximately 295 million kilometers from Earth.The resolution of the new ALMA observations is a vast improvement over earlier observations made at similar wavelengths and is enough to clearly resolve the irregular shape of the asteroid and potentially tease out prominent surface featuresPlease rate and comment, thanks!Image Credit: European Southern Observatory
Image Of Distant Einstein Ring Captivates Social Media
Chile’s ALMA radio telescope has captured a highly detailed image of a nearly contiguous Einstein ring.
Chile’s ALMA radio telescope has captured a highly detailed image of a complete Einstein ring. The light itself is emitting from a starburst galaxy located about 12 billion light years from earth. What’s making it appear circular is another galaxy that is positioned between it and Earth. The closer galactic entity is causing a bending of the light that passes over it, resulting in a phenomenon called gravitational lensing. That such an event can occur was foreseen in Albert Einstein’s theory of relativity, which is how the ring-like features got their name. Given the distance of the light source, what’s being seen from Earth now was actually emitted back when the universe was in its nascent stages. The study of such emanations is among the ways scientists gain a greater understanding of what the early days of space were like. The Einstein ring will aid in those efforts by allowing astronomers to better study the hidden galaxy. Such an endeavor could result in, “…a reconstruction of the true image of the distant galaxy."

It will enable transformational research into the physics of the cold Universe, probe the first stars and galaxies, and directly image the formation of planets.Since September 2014 ALMA has been observing the Universe using its longest ever baselines, with antennas separated by up to 15 kilometres. This Long Baseline Campaign will continue until 1 December 2014. The baseline is the distance between two of the antennas in the array. As a comparison, other facilities operating at millimetre wavelengths provide antennas separated by no more than two kilometres. The maximum possible ALMA baseline is 16 kilometres. Future observations at shorter wavelengths will achieve even higher image sharpness.The Atacama Large Millimeter/submillimeter Array (ALMA), an international astronomy facility, is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile. ALMA is funded in Europe by the European Southern Observatory (ESO), in North America by the U.S. National Science Foundation (NSF) in cooperation with the National Research Council of Canada (NRC) and the National Science Council of Taiwan (NSC) and in East Asia by the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Academia Sinica (AS) in Taiwan. ALMA construction and operations are led on behalf of Europe by ESO, on behalf of North America by the National Radio Astronomy Observatory (NRAO), which is managed by Associated Universities, Inc. (AUI) and on behalf of East Asia by the National Astronomical Observatory of Japan (NAOJ). The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA.Numerous technical papers related to ALMA were presented at the 2014 SPIE symposium on Astronomical Telescopes and Instrumentation.

Video of a collision between two galaxies, leading to the formation of a disk galaxy. Upon merging, the shape of the galaxies is disturbed by gravitational interaction and grow into a galaxy with a disk structure. Observations of colliding galaxies using ALMA and other radio telescopes have revealed that collisions between galaxies are likely to result in a galaxy with a gaseous disk structure. This is an important result, which gives us a clue about how disk galaxies like our own Milky Way form. For decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the the first time, researchers using ALMA and a host of other radio telescopes have found direct evidence that merging galaxies can instead form pancake galaxies, and that this outcome is in fact quite common. This surprising result could explain why there are so many spiral galaxies like the Milky Way in the Universe. An international research group led by Junko Ueda, a Japan Society for the Promotion of Science postdoctoral fellow, has made surprising observations, with ALMA and other radio telescopes, that most galaxy collisions in the nearby Universe (within 40–600 million light-years from Earth) result in so-called disc galaxies. These galaxies, including spiral galaxies like the Milky Way and lenticular galaxies, are defined by pancake-shaped regions of dust and gas, and are distinct from the category of elliptical galaxies. It has, for some time, been widely accepted that merging disc galaxies would eventually form an elliptically shaped galaxy. During these violent interactions the galaxies do not only gain mass as they merge or cannibalise each-other, but they are also changing their shape throughout cosmic time, and therefore changing type along the way. Computer simulations from the 1970s predicted that mergers between two comparable disc galaxies would result in an elliptical galaxy. The simulations predict that most galaxies today are elliptical, clashing with observations that over 70% of galaxies are in fact disc galaxies. However, more recent simulations have suggested that collisions could also form disc galaxies. To identify the final shapes of galaxies after mergers observationally, the group studied the distribution of gas in 37 galaxies that are in their final stages of merging. The Atacama Large Millimeter/sub-millimeter Array (ALMA) and several other radio telescopes were used to observe emission from carbon monoxide (CO), an indicator of molecular gas. Distribution of gas in merging galaxies observed by radio telescopes. Contours indicate the radio intensity emitted from CO gas. The colour shows the motion of gas. The red color indicates gas is moving away from us while the blue colour is coming closer to us. The gradation from red to blue means that gas is rotating in a disc-like manner around the centre of the galaxy.

• Alma began full-scale operation in March and it has already spotted a star formation near the centre of the Milky Way's supermassive black hole
• Scientists say the Alma array is poised to reach its full potential next yearA £1 billion ($1.6 billion) 'time machine', which could reveal mysteries of the universe, is finally complete.
The last giant antenna for Alma, the world's largest land-based observatory, recently arrived in Chile allowing scientists to peer deeper into the cosmos than ever before.
It is hoped it will allow astronomers to learn about our origins by peering back to almost the first moments after the universe was formed.
A £1 billion 'time machine', which could finally reveal mysteries of the universe, is complete. The last giant antenna (pictured) for Alma, the world's largest land-based observatory, recently arrived in Chile allowing scientists to peer deeper into the cosmos than ever before
The Alma array is situated high on the Chajnantor Plateau, a remote area of the Atacama Desert in northern Chile at 16,400 feet (5,000 metres) above sea level.
There, the dryness and altitude create some of the best conditions for observing the night sky.
With the latest arrival, the observatory combines the forces of 66 radio antennae, most almost 40 feet (12 metres) in diameter.
Combined, they make the Atacama Large Millimeter/submillimeter Array (Alma) accurate enough to see a golf ball nine miles (15 km) away.

Combined, they make the Atacama Large Millimeter/submillimeter Array (Alma) accurate enough to see a golf ball nine miles (15 kilometres) awayWith all the antennae working in unison as a giant telescope, the observatory will provide astronomers with a window into the early universe.
This is where cosmic secrets wait to be discovered, said project director Pierre Cox, who added Alma is poised to reach its full potential next year.
'Up to now Alma's observations and data were published with 16 to 20 antennae, now we're going to have double that or more, hence there will be a jump in sensitivity: better, quicker and more data,' Cox said.
I think there will be a real stream of scientific results in the coming months and years.'
The new dish is the 25th European antenna to be transported up to the observatory.
It will work alongside 25 other antennae from North America and four from East Asia, as well as 12 smaller 22ft (7 metre) dishes from East Asia.
The $1.6 billion telescope, which began full-scale operation in March, has already spotted galaxies expelling gas and a star formation near the centre of the Milky Way's supermassive black hole.
It also has captured the first image of an icy ring around a distant star.
By collecting radio waves rather than optical light, Alma can look through the dense dust clouds of deep space.
This will give astronomers a glimpse of galaxies from just after the Big Bang.
It can also look at how individual stars and planets are formed. This could shine a light on our creation as it is believed the elements spewed out by dying stars went on the seed the sun, the planets and, eventually, humans."science and technology news" "science technology news" "news about science and technology" "science & technology news" "news on science and technology" "news science and technology" "news in science and technology" "science news" "science in the news" "news of science and technology" "science news in hindi" "technology science news" "science news technology"

The final antenna for the Atacama Large Millimeter/submillimeter Array (ALMA) project has been taken up to the high-level site at the ALMA Observatory, 5.000 meters above sea level. Its arrival completes the complement of 66 ALMA antennas on the Chajnantor Plateau in the Atacama Desert of northern Chile—where they will in future work together as one giant telescope. The 66th antenna was transported to the Array Operations Site (AOS) on Friday 13 June 2014. The 12-meter diameter dish is the 25th and final European antenna to be transported up to the Chajnantor Plateau. It will work alongside its European predecessors, as well as 25 North American 12-meter antennas and 16 East Asian (four 12-meter and twelve 7-meter) antennas. The global ALMA collaboration is the largest ground-based astronomical project in existence. ALMA probes the Universe using light with millimeter and submillimeter wavelengths, between infrared light and radio waves in the electromagnetic spectrum. Light at these wavelengths originates from vast cold clouds in interstellar space and from some of the earliest and most distant galaxies in the Universe. The telescope will provide astronomers with a window into the mysterious cold Universe where secrets of our cosmic origins are waiting to be discovered.

Supernova Space Dust Formation Observed by Alma Telescope
Images taken by the Alma Radio Telescope in Chile have revealed the formation of space dust particles in a supernova 168 thousand light years away from Earth.
Images taken by the Alma Radio Telescope in Chile have revealed the formation of space dust particles in a supernova 168 thousand light years away from Earth.Experts have long hypothesized that space dust is formed by exploding stars called supernovas, but this is the first time that telescopic images have proven that theory.By observing the progress of the supernova 1987A using before and after images, astronomers were able to identify an increase in the amount of surrounding space dust as more and more of the mass of the star turns to dust.Mikako Matsuura, a scientist associated with the study from University College London, is quoted as saying: "Today we know dust can be created in several ways, but in the early universe most of it must have come from supernovas. We finally have direct evidence to support that theory."Space dust is an important part of the formation of galaxies, so observing how it is created will help astronomers further understand the processes that occur in deep space.

23° 1' 9.42" S, 67° 45' 11.44" W
The Atacama Large Millimeter/sub-millimeter Array (ALMA) is an astronomical interferometer of radio telescopes in the Atacama desert of northern Chile. Since a high and dry site is crucial to millimeter wavelength operations, the array has been constructed on the Chajnantor plateau at 5000 metres altitude, near Llano de Chajnantor Observatory and Atacama Pathfinder Experiment. Consisting of 66 12-meter and 7-meter diameter radio telescopes observing at millimeter and sub-millimeter wavelengths, ALMA is expected to provide insight on star birth during the early universe and detailed imaging of local star and planet formation.
ALMA is an international partnership between Europe, the United States, Canada, East Asia and the Republic of Chile. Costing more than a billion US dollars, it is the most expensive ground-based telescope in operation. ALMA began scientific observations in the second half of 2011 and the first images were released to the press on 3 October 2011. The array has been fully operational since March 2013.
Ground breaking ceremony for the Atacama Large Millimeter Array (ALMA)
Scientists and dignitaries from Europe, North America and Chile are breaking ground today on what will be the world's largest, most sensitive radio telescope operating at millimeter wavelengths .
ALMA - the "Atacama Large Millimeter Array" - will be a single instrument composed of 64 high-precision antennas located in the II Region of Chile, in the District of San Pedro de Atacama, at the Chajnantor altiplano, 5,000 metres above sea level. ALMA 's primary function will be to observe and image with unprecedented clarity the enigmatic cold regions of the Universe, which are optically dark, yet shine brightly in the millimetre portion of the electromagnetic spectrum.
ALMA is an international astronomy facility. ALMA is an equal partnership between Europe and North America, in cooperation with the Republic of Chile, and is funded in North America by the U.S. National Science Foundation (NSF) in cooperation with the National Research Council of Canada (NRC), and in Europe by the European Southern Observatory (ESO) and Spain. ALMA construction and operations are led on behalf of North America by the National Radio Astronomy Observatory (NRAO), which is managed by Associated Universities, Inc. (AUI), and on behalf of Europe by ESO.
"ALMA will be a giant leap forward for our studies of this relatively little explored spectral window towards the Universe" , said Dr. Catherine Cesarsky , Director General of ESO. "With ESO leading the European part of this ambitious and forward-looking project, the impact of ALMA will be felt in wide circles on our continent. Together with our partners in North America and Chile, we are all looking forward to the truly outstanding opportunities that will be offered by ALMA , also to young scientists and engineers" .
"The U.S. National Science Foundation joins today with our North American partner, Canada, and with the European Southern Observatory, Spain, and Chile to prepare for a spectacular new instrument, " stated Dr. Rita Colwell , director of the U.S. National Science Foundation. " ALMA will expand our vision of the Universe with "eyes" that pierce the shrouded mantles of space through which light cannot penetrate." On the occasion of this groundbreaking, the ALMA logo was unveiled

The first successful movement of an ALMA antenna took place at the Operations Support Facility (OSF) on 8 July 2008. The antenna transporter "Lore", one of the two units manufactured by Scheuerle under contract by ESO and delivered recently at the OSF, has been used to move one 12-m antenna from their site erection facility to an external antenna pad for sky testing. 2008 - Source: www.eso.org/gallery
The Atacama Large Millimeter/submillimeter Array (ALMA) is an international astronomy project that consists of an astronomical interferometer formed from an array of radio telescopes, located at Llano de Chajnantor Observatory in the Atacama desert in northern Chile. The telescope is expected to revolutionize modern astronomy by providing an insight on star formation in the early universe and imaging local star and planet formation in great detail. With a cost in excess of one billion US dollars, it is the most ambitious ground-based telescope currently under construction.
The telescopes and their receivers are capable of detecting sub-millimeter and millimeter wavelengths. The array will have much higher sensitivity and higher resolution than existing sub-millimeter telescopes such as the single-dish James Clerk Maxwell Telescope or existing interferometer networks such as the Submillimeter Array or the IRAMPlateau de Bure facility.
