11 Dec 2019, 17:00 UTC Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA)Atacama Large Millimeter/submillimeter Array (ALMA)Funded by the U.S. National Science Foundation and its international partners (NRAO/ESO/NAOJ), ALMA is among the most complex and powerful astronomical observatories on Earth or in space. The telescope is an array of 66 high-precision dish antennas in northern Chile. See more here have spotted the light of a massive galaxy seen only 970 million years after the Big BangBig BangThe well-supported theory that some 13.8 billion years ago, the entire universe was staggeringly small, hot, and dense. In a fraction of an instant, the universe expanded and continues to expand to this day. . This galaxy, called MAMBO-9, is the most distant dusty star-forming galaxy that has ever been observed without the help of a gravitational lensGravitational LensThe effect when light from a distant object, such as a galaxy, is bent by the gravity of a massive object, such as another galaxy, before it reaches the Earth. If the two objects are perfectly aligned, the light from the distant object appears as a ring, to observers on Earth. This phenomenon is called an Einstein Ring, since its existence was predicted by Einstein in his theory of General Relativity. ... Next Previous
NASA's Goddard Space Flight Center 17 Jan 2020, 12:43 UTC A prototype oxygen plant has been set up in the Materials and Electrical Components Laboratory of the European Space Research and Technology Centre, ESTEC, based in Noordwijk in the Netherlands.
ESA Space Science 16 Jan 2020, 15:00 UTC ESA’s XMM-Newton has discovered that gas lurking within the Milky Way’s halo reaches far hotter temperatures than previously thought and has a different chemical make-up than predicted, challenging our understanding of our galactic home.
ESA Top News 16 Jan 2020, 08:30 UTC The Rosalind Franklin rover of the joint ESA-Roscosmos ExoMars mission completed a series of environmental tests at the end of 2019 at Airbus, Toulouse, France. This included final thermal and vacuum tests where the Rover is heated and cooled to simulate the temperatures of its journey through space and on the surface of Mars. For example, Rosalind Franklin can expect temperatures dropping to –120°C outside, and –50 °C inside the rover once on Mars. It must also be able to operate in less than one hundredth of Earth’s atmospheric pressure – and in a carbon dioxide-rich atmosphere.
NASA's Jet Propulsion Laboratory News and Features 15 Jan 2020, 22:17 UTC NASA will host a live program at 10 a.m. PST (1 p.m. EST) Wednesday, Jan. 22, to celebrate the far-reaching legacy of the agency's Spitzer Space Telescope - a mission that, after 16 years of amazing discoveries, soon will come to an end.
ESA Space Science 14 Jan 2020, 17:00 UTC Fifteen years ago today, ESA’s Huygens probe made history when it descended to the surface of Saturn’s moon Titan and became the first probe to successfully land on another world in the outer Solar System. However, during its descent, the probe began spinning the wrong way – and recent tests now reveal why.

SPACE.com 17 Jan 2020, 11:59 UTC A planet-hunting telescope recently made a new discovery about the Milky Way's past cannibalism. Data from NASA's Transiting Exoplanet Survey Satellite (TESS) showed the age of an ancient star in our galaxy that has a curious life story.
Astro Bob 16 Jan 2020, 18:42 UTC We’re naturally drawn to the bright and obvious in the night sky. Everyone knows Orion the hunter and many of us can find Sirius in Canis Major the Big Dog. Ditto for the Big Dipper. All this attention-grabbing leaves the lesser constellations to ply the sky with far fewer admirers. Let’s do something to correct that. We’ll start with a surprisingly easy but virtually unknown star group — at least among the general populace — called Canis Minor the Little Dog.
Centauri Dreams 16 Jan 2020, 16:57 UTC While we continue to labor over the question of planets around Alpha Centauri A and B, Proxima Centauri — that tiny red dwarf with an unusually interesting planet in the habitable zone — remains a robust source of new work. It’s surely going to be an early target for whatever interstellar probes we eventually send, and is the presumptive first destination of Breakthrough Starshot. Now we have news of a possible second planet here, though well outside the habitable zone. Nonetheless, Proxima Centauri c, if it is there, commands the attention.
Bad Astronomy 16 Jan 2020, 14:00 UTC At the center of our Milky Way galaxy sits a supermassive black hole — which astronomers named Sgr A* — with over 4 million times the Sun's mass. But it's not alone. Lots of other stuff is there, too, orbiting that black hole, including stars, gas, and dust. Over time, we can see these objects move, held sway by the incredible gravity of Sgr A*. In fact, the motions of several stars have told us a lot about the black hole itself.
Universe Today 16 Jan 2020, 10:27 UTC Astronomers have discovered another candidate exoplanet orbiting our neighbor, Proxima Centauri. A paper announcing these results was just published in the journal Science Advances. If confirmed, it will be the second exoplanet orbiting the star.
