But how do we know we live in a disk Galaxy, how do we know what it looks like, and how do we know that it is a spiral Galaxy? It might not be as simple as you think, because we can’t just fly out of the Milky Way and take a nice photo - the distances are far too great! So when you’re seeing one of those “you are here” t-shirts with an arrow pointing to a spiral galaxy, you’ve actually been fooled! However, don’t be too disappointed - with the new Gaia telescope astronomers can actually start to map out what the structure of our Galaxy looks like from within! Season 2 is still in the making - stay tuned!

NASA recently shared details of massive bubbles that our galaxy is blowing.

Fly through the galaxy with Museum astrophysicist Jackie Faherty, who takes us on a dazzling tour of new research and data visualizations made possible by recently released data from the Gaia space telescope. In April 2018, the European Space Agency’s Gaia observatory released its second data catalog, which includes the distances to over 1.3 billion stars. Faherty breaks down why this information is so revolutionary, and explains how this information is helping scientists and non-scientists alike understand the universe like never before.

The densely packed starfields at our galaxy's center are hidden behind dust clouds and only become visible in infrared light. In the near-infrared they begin to appear, but are reddened for much the same reason that sunlight turns red when filtered through a smoky cloud. The dense dust clouds begin to stand out at longer infrared wavelengths, taking on changing rainbows of color depending on which parts of the spectrum contribute to the image. The very coldest, densest dust will only start to glow at the very longest wavelengths of light, rendered in red in the far-infrared image in this sequence. Far-infrared: At these long infrared wavelengths, the hottest dust glows blue, while the coldest is red. Mid-infrared: Some of the hottest dust clouds begin to glow as one looks deeper into the infrared spectrum. Near-infrared: The myriad stars and shadows caused by dust clouds are more vivid at shorter wavelengths of light. ABOUT THE INFRARED UNIVERSE COLLECTION The human eye can only see visible light, but objects give off a variety of wavelengths of light. To see an object as it truly exists, we would ideally look at its appearance through the full range of the electromagnetic spectrum. Telescopes show us objects as they appear emitting different energies of light, with each wavelength conveying unique information about the object. The Webb Space Telescope will study infrared light from celestial objects with much greater clarity and sensitivity than ever before. Explore the Infrared Universe.

According to a report by Geek.com, a new discovery by researchers at the University of Michigan has uncovered our Milky Way galaxy's long-lost, and long-dead, stellar sibling. The new study shows that our nearest galactic neighbor, the Andromeda galaxy, cannibalized another massive galaxy two billion years ago. "A rich trail of evidence" left behind after the galaxy, named M32p, was devoured has helped scientists understand how disk galaxies like the Milky Way evolve and survive. It turns out the consumed galaxy was at least 20 times larger than any galaxy that ever merged with the Milky Way, and had been the third-largest member of the so-called Local Group. https://www.geek.com/news/scientists-shocked-to-discover-milky-ways-long-lost-sibling-1747200/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

According to a new study published Monday in the journal Nature Astronomy, two billion years ago, our Milky Way galaxy's sibling, known as M32p, was violently cannibalized by our closest and largest galactic neighbor, Andromeda. CNN reports that the large neighboring galaxy is expected to have consumed hundreds of surrounding smaller galaxies. Before being consumed, the M32p galaxy was reportedly the third largest galaxy behind Andromeda and the Milky Way and was at least 20 times larger than any galaxy that ever merged with the Milky Way. Both evidence and computer simulations allowed researchers to reconstruct the events leading up to galaxy M32p's demise approximately 2 billion years ago. https://www.cnn.com/2018/07/23/world/milky-way-galaxy-sibling-m32/index.html http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Our solar system and sun is located inside a pancake shaped galaxy. Imagine a scale model where the plane of the Milky Way is a DVD, and the central bulge is a ping pong ball glued in the center. It is this narrow plane that we see across the sky on a sufficiently dark night from Earth, from our vantage point inside it. Dust blocks much of our view. But at other wavelengths astronomers can probe the heart of our galaxy. The center of our Milky Way Galaxy, located 26,000 light-years away, houses a black hole as massive as a million suns, surrounded by very dense nest of stars and bright clouds. The density of stars in the innermost regions of the Milky Way is up to one million times greater than in our portion of the galaxy. This region contains extreme and unusual conditions that can influence the types of stars that reside there. The density of stars and clouds creates streaming patterns. There are large massive star clusters that cannot not be found outside that region. The radiation environment is intense in the galactic center. The near-infrared image (Hubble) shows the knots of cloud edges and emission that mark the plane of our galaxy. The mid-infrared image (Spitzer) highlights the clouds of gas and dust and star forming regions. The X-ray image (Chandra) tracks the most luminous and powerful stars in the area conspicuously revealing the galactic center region itself - including the million-solar mass black hole at the very hub of our galaxy. In addition, several other X-ray emitting locations can be seen, linked to massive star clusters. Video: NASA, ESA, and G. Bacon (STScI) Image Credits: NASA, ESA, CXC, SSC and STScI

The Milky Way’s Bulge: From a Hypothesized Blob to a Remarkably Detailed Picture David Nataf of Johns Hopkins University The central bulge of our Milky Way galaxy is host to roughly 30 percent of its stars, including a substantial fraction of both the oldest stars and the most metal-rich stars. The ages of the stars indicate that some formed via hierarchical collapse early in the universe, while most formed later on, due to dynamical processes within the disk. The differences in chemical abundances among the stars may have effects on the formation of planets and the evolution of life. Astronomers’ understanding and characterization of the Milky Way bulge creates a relatively complex picture, but it is still incomplete.

According to astronomers at the University of New South Wales in Sydney and Ege University in Turkey, the Milky Way is clogged with toxic grease. UNSW Sydney professor Tim Schmidt said in a statement, "This space grease is not the kind of thing you’d want to spread on a slice of toast. It’s dirty, likely toxic, and only forms in the environment of interstellar space. According to Geek.com, the teams have concluded that there are about 100 greasy carbon atoms for every million hydrogen atoms, accounting for between one quarter and one half of the available carbon. https://www.geek.com/news/study-milky-way-congested-with-toxic-grease-1744691/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Phillips Auditorium Joao Alves University of Vienna Host: Alyssa Goodman Abstract: Most of what we know about star and planet formation has been obtained from spatial 2D observations of the local Galactic neighborhood (d ~ 1 kpc), collected over the last 70 years. During this time we have built a pragmatic, ​although simplified, view of the local complexes, establishing a series of ground truths that guide today's star formation research. For example, we use Orion as the template for massive star formation and Taurus for low-mass star formation. We have embraced supersonic turbulence as a fundamental pillar of the star formation process, but have not identified its source. We have organized groups of young stars as either bound clusters or associations and wondered about the origin of an all-sky structure we call Gould’s belt. Recently, we found that this view might be up for revision, as we have seen evidence for a new and more significant arrangement of young massive stars in the local neighborhood we call Blue Streams. These streams appear to be several hundred pc long and display monotonic age sequences, suggestive of a common origin at Galactic scales. If real, Blue Streams would play a critical role in understanding the structure of ​the ​local ISM, would give a much-needed context to local star formation, and even allow the prediction of the "galactic weather" our solar system will face in the future. In this talk, a week and a day after Gaia Data Release 2, I will present the very latest from the 3D view of the local neighborhood and will try to validate or reject old and new ideas.

A remarkable new map of the Milky Way was recently released by the European Space Agency.

*Milky Way is as big as Andromeda A new study claims our nearest big neighbour the Andromeda galaxy M-31 and our own galaxy the Milky Way are about the same mass. The findings contradicts earlier studies which concluded that Andromeda was two to three times larger than the Milky Way. *New Hubble constant hinting at strange new physics beyond the standard model Astronomers have used NASA's Hubble Space Telescope to make the most precise measurements yet of the expansion rate of the universe since it was first calculated nearly a century ago. Intriguingly, the new results are forcing astronomers to consider that they may be seeing evidence of something unexpected at work in the universe. *The most distant supernova ever seen Astronomers have confirmed the discovery of the most distant supernova ever detected. The findings claim the huge cosmic explosion took place 10.5 billion years ago – meaning it’s taken some three-quarters of the age of the universe for light from the blast to reach Earth. *The Science Report Climate change now so bad that sea levels will continue to rise even if all Paris targets are reached. Up to 30 percent of teenage school kids now involved in sexting. The first three-dimensional computer models of the thylacine or Tasmanian Tiger.

A new visualization provides an exceptional virtual trip — complete with a 360-degree view — to the center of our home galaxy, the Milky Way.

The Earth is located about 26,000 light years, or about 200,000 trillion miles, from the center of the Galaxy. While humans cannot physically travel there, scientists have been able to study this region by using data from powerful telescopes. A new visualization, based on data from NASA's Chandra X-ray Observatory and other telescopes, lets viewers explore the Milky Way's center. In this 360-degree movie, viewers can see powerful winds from giant stars around the Galaxy's supermassive black hole. Scientists are using this visualization to examine the effects from the black hole on its stellar neighbors.

A 360-degree movie immerses viewers into a simulation of the center of our Galaxy. This visualization was enabled by data from Chandra and other telescopes and allows viewers to control their own exploration of this region. From the vantage point of the Milky Way's supermassive black hole, Sgr A*, the viewer can see about 25 Wolf-Rayet stars (white, twinkling objects) as they continuously eject stellar winds (black to red to yellow color scale). These winds collide with each other, and then some of this material (yellow blobs) spirals towards Sgr A*. The movie shows two simulations, each of which start around 350 years in the past and span 500 years. The first simulation shows Sgr A* in a calm state, while the second contains a more violent Sgr A* that is expelling its own material, thereby turning off the accretion of clumped material (yellow blobs) that is so prominent in the first portion.

September 14, 2017 Phillips Auditorium Jennifer Johnson Ohio State University Host: Aaron Dotter Abstract: The past 10 billion years have been an exciting time for the Milky Way's disk. Based on over 100,000 stars with SDSS/APOGEE near-infrared spectra, I will review work on its age distribution, both radially and vertically, and the evidence for radial mixing of populations. I will present work on the large-scale chemical cartography of the Milky Way disk. I will discuss current efforts to calibrate "chemical age" indicators, in particular C/N in red giants, using stellar cluster data and asteroseismic ages. I will conclude with the most ambitious program yet to study the Milky Way disk -- the ~5 million star Milky Way Mapper, part of the After-Sloan-IV proposal.

The findings cast doubt on previous ideas that the glow might be evidence of dark matter -- a mysterious invisible substance that accounts for 85 percent of all matter in the universe -- but which has so far evaded detection. *Gravitationally lensed supernova Astronomers have discovered their first gravitationally lensed thermonuclear supernova. The new observations provide new ways of studying the accelerating expansion of the Universe due to a mysterious force called dark energy – as well as gravity and distribution of a mysterious substance called dark matter across the cosmos. *Cassini finds big empty close to Saturn NASA’s Cassini scientists say the region between Saturn and its rings is relatively dust free. However, the discovery made during Cassini’s first plunge inside the rings has come as somewhat of a surprise. *SpaceX launches its first spy satellite SpaceX has successfully launched its first top secret spy satellite for the National Reconnaissance Office. It was a case of second time lucky for the classified payload after a faulty first stage liquid oxygen temperature sensor detected an anomaly the previous day resulting in the launch being scrubbed. The NROL-76 payload was blasted into orbit aboard a Falcon 9 rocket from pad 39A at the Kennedy Space Centre at the Cape Canaveral Air Force Base in Florida.

A black hole is so dense that not even light can escape it. So we can't possibly photograph one, can we? Yes, we can. More accurately, we can observe its silhouette or shadow against the glowing disk of material it’s swallowing. The Event Horizon Telescope will unite facilities around the globe to form an Earth-sized telescope. With it, we will get our first detailed look at the giant black hole at the center of the Milky Way. And we will put Einstein’s theory to the ultimate test.

Launched in December 2013, Gaia is destined to create the most accurate map yet of the Milky Way. By making accurate measurements of the positions and motions of stars in the Milky Way, it will answer questions about the origin and evolution of our home galaxy. The first intermediate data release, containing among other things three-dimensional positions and two-dimensional motions of a subset of two million stars, demonstrates that Gaia’s measurements are as precise as planned, paving the way to create the full map of one billion stars to be released towards the end of 2017.

Launched in December 2013, Gaia is destined to create the most accurate map yet of the Milky Way. By making accurate measurements of the positions and motions of roughly 1% of the total population of stars in the Milky Way, it will answer questions about the origin and evolution of our home galaxy. The first intermediate data release, containing, among other things, three-dimensional positions and two dimensional motions of a subset of two million stars, demonstrates that Gaia’s measurements are as precise as planned, paving the way to create the full map of one billion stars to be released towards the end of 2017.

A visualisation of how Gaia scanned the sky during its first 14 months of operations, between July 2014 and September 2015. The oval represents a projection of the celestial sphere, with different portions of the sky gradually appearing, according to when and how frequently they were scanned by Gaia. The satellite scans great circles on the sky, with each scan lasting about 6 hours. During the first month, the scanning procedure was such that the ecliptic poles were always included. This meant that Gaia observed the stars in those regions many times, providing an invaluable database for the initial calibration of the observations. Then, starting on 21 August 2014, the satellite started its main survey, employing a scanning ‘law’ designed to achieve the best possible coverage of the whole sky. Data collected over Gaia's first 14 months make up the mission’s first data release. Based on these observations, scientists produced a map of the sky, showing the density of stars observed by Gaia. Brighter regions indicate denser concentrations of stars, while darker regions correspond to patches of the sky where fewer stars are observed. The Galactic Plane, where most of the Milky Way’s stars reside, is visible as the brightest portion of the map: a horizontal strip that is especially bright at the centre. Darker regions across the Galactic Plane correspond to dense clouds of interstellar gas and dust that absorb starlight along the line of sight. Stellar clusters also appear, sprinkled across the image alongside a handful of nearby galaxies – most notably the Large and Small Magellanic Clouds in the lower right. A number of artefacts, reflecting Gaia's scanning law, are also visible on the all-sky map. As this map is based on observations performed during the mission’s first year, the survey is not yet uniform across the sky. These artefacts will gradually disappear as more data are gathered during the five-year mission.

A virtual journey, from our Solar System through the Milky Way, based on data from the first release of ESA’s Gaia satellite. The journey starts by looking back at the Sun, surrounded by its eight planets. We then move away from the Sun and travel towards and around the Hyades star cluster, the closest open cluster to the Solar System, some 150 light-years away. The 3D positions of the stars shown in the animation are drawn from the Tycho-Gaia Astrometric Solution (TGAS), which combines information from Gaia’s first year of observations with the earlier Hipparcos and Tycho-2 Catalogues, both based on data from ESA’s Hipparcos mission. This new dataset contains positions on the sky, distances and proper motions of over two million stars. It is twice as precise and contains almost 20 times as many stars as the previous reference for astrometry, the Hipparcos Catalogue. The journey continues showing the full extent size of the stars contained in the Tycho-Gaia Astrometric Solution, all relatively near to the Sun, in the overall context of our Milky Way galaxy. The final Gaia catalogue will contain the most detailed 3D map ever made of the Galaxy, charting a billion stars – about 1% of the Milky Way’s stellar content – to unprecedented accuracy.
