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.

ESA Top News 30 Apr 2020, 15:30 UTC A reasonably small 4-8 m asteroid recently flew by Earth, passing close to satellites orbiting in the geostationary ring at a distance of about 42 735 km from Earth’s centre and only about 1200 km from the nearest satellite.
NASA's Goddard Space Flight Center 29 Apr 2020, 18:16 UTC New analysis published today in the Astrophysical Journal Letters provides a possible explanation for the origin of switchbacks — sudden reversals in the magnetic field of the solar wind — first observed by Parker Solar Probe during its November 2018 solar flyby. A new paper by scientists Justin Kasper and Lennard Fisk of the University of Michigan suggests the origin of switchbacks are related to the way the Sun maintains and moves magnetic field lines that stretch out into the solar system, tied to a theory first proposed more than two decades ago.
