ESA Top News 25 Jan 2021, 15:00 UTC ESA’s exoplanet mission Cheops has revealed a unique planetary system consisting of six exoplanets, five of which are locked in a rare rhythmic dance as they orbit their central star. The sizes and masses of the planets, however, don’t follow such an orderly pattern. This finding challenges current theories of planet formation.

NASA's Goddard Space Flight Center 21 Jan 2021, 18:42 UTC Located in the constellation of Virgo (The Virgin), around 50 million light-years from Earth, the galaxy NGC 4535 is truly a stunning sight to behold. Despite the incredible quality of this image, taken from the NASA/ESA Hubble Space Telescope, NGC 4535 has a hazy, somewhat ghostly, appearance when viewed from a smaller telescope. This led amateur astronomer Leland S. Copeland to nickname NGC 4535 the “Lost Galaxy” in the 1950s.
ESO Top News 20 Jan 2021, 10:33 UTC Galaxies begin to “die” when they stop forming stars, but until now astronomers had never clearly glimpsed the start of this process in a far-away galaxy. Using the ALMA, astronomers have seen a galaxy ejecting nearly half of its star-forming gas.
HubbleSite NewsCenter -- Latest News Releases 14 Jan 2021, 21:30 UTC Astronomers are winding back the clock on the expanding remains of a nearby, exploded star. By using NASA's Hubble Space Telescope, they retraced the speedy shrapnel from the blast to calculate a more accurate estimate of the location and time of the stellar detonation.

HubbleSite NewsCenter -- Latest News Releases 12 Jan 2021, 17:00 UTC How dark is the sky, and what does that tell us about the number of galaxies in the visible universe? Astronomers can estimate the total number of galaxies by counting everything visible in a Hubble deep field and then multiplying them by the total area of the sky. But other galaxies are too faint and distant to directly detect. Yet while we can’t count them, their light suffuses space with a feeble glow.
Carnegie Science 12 Jan 2021, 15:28 UTC In a case of comic mistaken identity, an international team of astronomers revealed that what they once thought was a supernova is actually periodic flaring from a galaxy where a supermassive black hole gives off bursts of energy every 114 days as it tears off chunks of an orbiting star.
