EUROPEAN SOUTHERN OBSERVATORY (ESO)

Phosphorus, present in our DNA and cell membranes, is an essential element for life. But how it arrived on the early Earth is something of a mystery. Astronomers have now traced the journey of phosphorus from star-forming regions to comets using the combined powers of ALMA and the European Space Agency’s probe Rosetta.

This animation shows the key results from a study that has revealed the interstellar thread of phosphorus, one of life’s building blocks.  Thanks to ALMA, astronomers could pinpoint where phosphorus-bearing molecules form in star-forming regions like AFGL 5142. The background of this animation shows a part of the night sky in the constellation of Auriga, where the star-forming region AFGL 5142 is located. The ALMA image of this object appears on the top left, and one of the locations where the team found phosphorus-bearing molecules is indicated by a circle. The most common phosphorus-bearing molecule in AFGL 5142 is phosphorus monoxide, represented in orange and red in the diagram that appears on the bottom left. Another molecule found was phosphorus nitride, represented in orange and blue.  Using data from the ROSINA instrument onboard ESA’s Rosetta, astronomers also found phosphorus monoxide on comet 67P/Churyumov–Gerasimenko, which appears on the bottom right at the end of the video. This first sighting of phosphorus monoxide on a comet helps astronomers draw a connection between star-forming regions, where the molecule is created, all the way to Earth, where it played a crucial role in starting life.

This video shows one of the gas halos newly observed with the MUSE instrument on ESO’s Very Large Telescope superimposed to an older image of a galaxy merger obtained with ALMA. The large-scale halo of hydrogen gas is shown in blue, while the ALMA data is shown in orange. This 3D view was rendered using real data from MUSE and ALMA.  The halo is bound to the galaxy, which contains a quasar at its centre. The faint, glowing hydrogen gas in the halo provides the perfect food source for the supermassive black hole at the centre of the quasar.  The objects in this 3D view are located at redshift 6.2, meaning they are being seen as they were 12.8 billion years ago. While quasars are bright, the gas reservoirs around them are much harder to observe. But MUSE could detect the faint glow of the hydrogen gas in the halos, allowing astronomers to finally reveal the food stashes that power supermassive black holes in the early Universe.

This animation depicts a quasar in the early Universe; as we zoom out, we notice the quasar is surrounded by a giant gas halo. The quasar, in orange, has two powerful jets and a supermassive black hole at its centre. The gas halo of glowing hydrogen gas is represented in blue. A team of astronomers surveyed 31 distant quasars, seeing them as they were more than 12.5 billion years ago, at a time when the Universe was still an infant, only about 870 million years old. They found that 12 quasars were surrounded by enormous gas reservoirs: halos of cool, dense hydrogen gas extending 100 000 light years from the central black holes and with billions of times the mass of the Sun. These gas stashes provide the perfect food source to sustain the growth of supermassive black holes in the early Universe.

This video compares a visible light wide-field view (part of the Digitized Sky Survey 2) of the Milky Way’s central regions with a new near-infrared image taken with the HAWK-I instrument on ESO’s Very Large Telescope. The video starts by showing a visible light image of the Milky Way central regions, filled with vast numbers of stars. A moving slider then reveals that far more stars, hidden behind clouds of dust, are revealed when this region is observed in the near-infrared.

Researchers using ESO’s Very Large Telescope have, for the first time, found evidence of a giant planet associated with a white dwarf star. The planet orbits the hot white dwarf, the remnant of a Sun-like star, at close range, causing its atmosphere to be stripped away and form a disc of gas around the star.

This animation shows the white dwarf WDJ0914+1914 and its Neptune-like exoplanet. Since the icy giant orbits the hot white dwarf at close range, the extreme ultraviolet radiation from the star strips away the planet’s atmosphere. While most of this stripped gas escapes, giving the planet a comet-like tail, some of it swirls into a disc, itself accreting onto the white dwarf.

Stars such as our Sun burn hydrogen in their cores for most of their lives. Once they run out of this fuel, they puff up into red giants, becoming hundreds of times larger and engulfing nearby planets. As shown in this animation, in the case of the Solar System this will include Mercury, Venus, and even Earth, which will all be consumed by the red-giant Sun in about 5 billion years. Eventually, Sun-like stars lose their outer layers, leaving behind only a burnt-out core, a white dwarf. Such stellar remnants can still host planets, and many of these stars exist in our galaxy. However, until 2019, scientists had never found evidence of a surviving giant planet around a white dwarf. The detection of a Neptune-like exoplanet at WDJ0914+1914 may be the first of many orbiting such stars.

This animation shows where Hygiea’s orbit is in our Solar System. Like Ceres, Hygiea is in the main asteroid belt, which is located between the orbits of Mars and Jupiter. While Hygiea was thought to be an asteroid, new observations with the SPHERE instrument on the VLT have revealed that Hygiea is spherical in shape, meaning it could be reclassified as a dwarf planet. This would make it the smallest dwarf planet yet in our Solar System, after Ceres. More information and download options: http://www.eso.org/public/videos/eso1918b/ Credit: ESO/spaceengine.org

Computational simulation of the fragmentation and reassembly that led to the formation of Hygiea and its family of asteroids, following an impact with a large object. While changes in the shape of Hygiea occur after the impact, the dwarf-planet candidate eventually acquires a round shape.

In November 2018 the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope pinpointed a fast radio burst, named FRB 181112. Follow-up observations with ESO’s Very Large Telescope (VLT) and other telescopes revealed that the radio pulses have passed through the halo of a massive galaxy on their way toward Earth. This finding allowed astronomers to analyse the radio signal for clues about the nature of the halo gas. The video is available in 4K UHD.

This time-lapse was taken by a team of researchers observing the total solar eclipse visible from ESO’s La Silla Observatory on 2 July 2019. While their scientific observations used the REM telescope, visible in this image, they couldn’t resist capturing the moment as humans saw it as well. It follows the eclipse through totality, then continues to follow the sun as it sets towards the horizon. The bright streaks crossing the sky may look like shooting stars, but they're actually airplanes flying at normal speed — giving a sense of how much time is condensed into this short video.

On 2 July 2019 a total solar eclipse was visible from ESO’s La Silla Observatory in Chile. 1000 people came from around the world for the chance to view this amazing event in an equally amazing place. These visitors saw the Moon cover the Sun completely, briefly turning day into night — a rare event that La Silla won’t see again until 2231. The video is available in 4K UHD.

The unique capabilities of the SPHERE instrument on ESO’s Very Large Telescope have enabled it to obtain the sharpest images of a double asteroid as it flew by Earth on 25 May. While this double asteroid was not itself a threatening object, scientists used the opportunity to rehearse the response to a hazardous Near-Earth Object (NEO), proving that ESO’s front-line technology could be critical in planetary defence. This artist’s impression shows both components of the double asteroid 1999 KW4 tumbling through space during its Earth fly-by.

ATTRACT, a Horizon 2020 research and innovation project funded by the European Union and backed by a consortium of 9 partners including ESO, has announced 170 breakthrough ideas which will each receive €100,000 to develop technologies that have the potential to change society. Two ESO-related projects were among those selected. One — 3D-CANCER-SPEC — will bring astronomical technology to bear against cancer, one of the leading cause of death worldwide. The video is available in 4K UHD. The ESOcast Light is a series of short videos bringing you the wonders of the Universe in bite-sized pieces.
