15 Oct 2019, 17:00 UTC At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used 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 to study this cloud in more detail, they made an unexpected discovery that could explain why supermassive black holes grew so rapidly in the early Universe. “Thanks to the spectacular resolution of ALMA, we measured the movement of gas in the inner orbits around the black hole,” explains Violette Impellizzeri of the National Radio Astronomy Observatory (NRAO), working at ALMA in Chile and lead author on a paper published in the Astrophysical Journal. “Surprisingly, we found two disks of gas rotating in opposite directions.”Supermassive black holes already existed when the Universe was young – just a billion years after the Big Bang. But how these extreme objects, whose masses are up to billions of times the mass of the Sun, had time ... Next Previous

Hubble Space Telescope News 16 Oct 2019, 14:00 UTC On 12 October 2019, the NASA/ESA Hubble Space Telescope provided astronomers with their best look yet at an interstellar visitor — Comet 2I/Borisov — which is believed to have arrived here from another planetary system elsewhere in our galaxy.
MIT 15 Oct 2019, 08:42 UTC Astronomers at MIT and elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, high-energy stages of star formation.
Kavli Institute for Cosmology, Cambridge 14 Oct 2019, 07:40 UTC Members of KICC since its foundation and longstanding members of the Planck collaboration, Prof. George Efstathiou and Dr. Steven Gratton recently uploaded their detailed reanalysis of the Planck satellite Cosmic Microwave Background data to the arXiv preprint server.
NASA's Goddard Space Flight Center 11 Oct 2019, 13:00 UTC The NASA/ESA Hubble Space Telescope sees galaxies of all shapes, sizes, luminosities and orientations in the cosmos. Sometimes, the telescope gazes at a galaxy oriented sideways — as shown here. The spiral galaxy featured in this Hubble image is called NGC 3717, and it is located about 60 million light-years away in the constellation of Hydra (the Sea Serpent).
NASA's Goddard Space Flight Center 11 Oct 2019, 07:17 UTC The discovery of ice deposits in craters scattered across the Moon’s south pole has helped to renew interest in exploring the lunar surface, but no one is sure exactly when or how that ice got there. A new study suggests that while a majority of those deposits are likely billions of years old, some may be more recent.
NASA's Goddard Space Flight Center 9 Oct 2019, 14:00 UTC The center of our galaxy is a crowded place: A black hole weighing 4 million times as much as our Sun is surrounded by millions of stars whipping around it at breakneck speeds. This extreme environment is bathed in intense ultraviolet light and X-ray radiation. Yet much of this activity is hidden from our view, obscured by vast swaths of interstellar dust.

New Scientist 16 Oct 2019, 19:00 UTC Titan is the only other place in the solar system with liquid oceans on its surface, but it also has huge swathes of desert covered in sand dunes. The material that makes up these dunes is commonly assumed to have fallen from the sky, but a new study suggests it may have been made on the ground instead.
Geekwire 16 Oct 2019, 16:06 UTC It’s a bit of a stretch to call them spacesuits, but the “spacewear” clothing line unveiled today by Virgin Galactic and Under Armour looks comfortable enough to wear even if you’re not rocketing to the edge of space.
Starts With a Bang! 16 Oct 2019, 14:01 UTC If there’s one lesson that humanity should have learned from the 20th century, it’s this: the Universe rarely behaves the way our intuition leads us to suspect. At the start of the 1900s, we thought the Universe was governed by Newtonian gravity. We thought that the Universe was static, stationary, and infinitely old, with no beginning and no end. And we couldn’t even be sure whether the Milky Way was one of many galaxies, or whether it encompassed everything there was. Of course, developments in both theory and observation changed all of this. Newtonian gravity was superseded by General Relativity, which demonstrated that a static Universe would be unstable. Spirals (and later ellipticals) were determined to be their own “island Universes” far outside of the Milky Way, each with billions of stars of their own. And instead of an infinitely old Universe, we live in one that got its start 13.8 billion years ago during the hot Big Bang. This picture itself was revolutionary, but led to a brand new question: how did the Universe grow up?
Bad Astronomy 16 Oct 2019, 13:00 UTC Asteroids are chunks of rock and metal left over from the formation of the solar system, battered and shattered, orbiting the Sun all over the place, but with the vast majority of big ones between the orbits of Mars and Jupiter. Hubble Space Telescope is an Earth-orbiting observatory that looks at objects all over the Universe, which appear all over the sky. Above Earth's atmosphere it has darker skies and sharp eyesight, allowing it to peer deeply into space.
