ESA Top News 12 May 2020, 13:00 UTC Jupiter’s moon Europa is a fascinating world. On its surface, the moon appears to be scratched and scored with reddish-brown scars, which rake across the surface in a crisscrossing pattern. These ‘scars’ are etched into a layer of water ice, which is thought to be at least several kilometres thick and covering a vast – and potentially habitable – subsurface ocean.
NASA's Chandra X-ray Observatory 11 May 2020, 13:00 UTC Several hundred million years ago, two galaxy clusters collided and then passed through each other. This mighty event released a flood of hot gas from each galaxy cluster that formed an unusual bridge between the two objects. This bridge is now being pummeled by particles driven away from a supermassive black hole.
NASA's Goddard Space Flight Center 8 May 2020, 12:50 UTC In the depths of the night sky lies a barred spiral galaxy called NGC 3583, imaged here by the NASA/ESA Hubble Space Telescope. This is a barred spiral galaxy with two arms that twist out into the universe. This galaxy is located 98 million light-years away from the Milky Way. Two supernovae exploded in this galaxy, one in 1975 and another, more recently, in 2015.
HubbleSite NewsCenter -- Latest News Releases 7 May 2020, 19:00 UTC With thunderheads that tower forty miles high and stretch half the width of a continent, hurricane-force winds in enormous storms that rage for centuries, and lightning three times as powerful as Earth's strongest superbolts, Jupiter—king of the planets—has proven itself a more-than-worthy namesake to the supreme Roman god of sky and thunder.
NASA's Goddard Space Flight Center 7 May 2020, 13:41 UTC NASA has selected a new pathfinding CubeSat mission to gather data not collected since the agency flew the Dynamics Explorer in the early 1980s.
HubbleSite NewsCenter -- Latest News Releases 5 May 2020, 16:00 UTC Brown dwarfs, often called “failed stars,” weigh up to 80 times as much as Jupiter, yet their gravity compacts them to about the size of Jupiter in diameter. And like Jupiter, brown dwarfs can have clouds and weather. Astronomers have found evidence that the closest known brown dwarf, Luhman 16A, has Jupiter-like cloud bands. In contrast its companion brown dwarf, Luhman 16B, shows signs of patchy clouds.
MIT 4 May 2020, 16:00 UTC As new and more powerful telescopes blink on in the next few years, astronomers will be able to aim the megascopes at nearby exoplanets, peering into their atmospheres to decipher their composition and to seek signs of extraterrestrial life. But imagine if, in our search, we did encounter alien organisms but failed to recognize them as actual life.
NASA's Goddard Space Flight Center 1 May 2020, 12:28 UTC This sparkling spiral galaxy looks almost stretched across the sky in this new image from the NASA/ESA Hubble Space Telescope. Known as NGC 4100, the galaxy boasts a neat spiral structure and swirling arms speckled with the bright blue hue of newly formed stars.
