ESA Top News 28 Jan 2019, 15:00 UTC Investigating the history of our cosmos with a large sample of distant ‘active’ galaxies observed by ESA’s XMM-Newton, a team of astronomers found there might be more to the early expansion of the Universe than predicted by the standard model of cosmology.
HubbleSite NewsCenter -- Latest News Releases 28 Jan 2019, 14:00 UTC The Space Telescope Science Institute (STScI) in Baltimore, Maryland, in conjunction with the University of Hawai'i Institute for Astronomy (IfA), is releasing the second edition of data from Pan-STARRS — the Panoramic Survey Telescope & Rapid Response System — the world's largest digital sky survey. This second release contains over 1.6 petabytes of data (a petabyte is 1015 bytes or one million gigabytes), making it the largest volume of astronomical information ever released. The amount of imaging data is equivalent to two billion selfies, or 30,000 times the total text content of Wikipedia. The catalog data is 15 times the volume of the Library of Congress.
ESA Top News 25 Jan 2019, 15:05 UTC On the night between Sunday 20 and Monday 21 January, many people across the world were treated to the spectacle of the lunar eclipse. During this phenomenon, the Moon is engulfed by Earth’s shadow and the only sunlight that reaches its surface is diffracted by our planet’s atmosphere, giving it a red-orange tint.
HubbleSite NewsCenter -- Latest News Releases 24 Jan 2019, 18:00 UTC Two's company and three's a crowd. But thousands are a mosh pit. That's the case in the giant Coma cluster of more than 1,000 galaxies. Hubble spotted a wayward spiral galaxy losing its gas as it plunges toward the center of the massive cluster and is roughed up as it plows through the intergalactic medium. Telltale evidence lies in a long, thin streamer of material that is stretching like taffy from the galaxy's core and on into intergalactic space. Gas is the lifeblood of a galaxy, fueling the birth of new stars. Once it is stripped of all of its gas, the galaxy, named D100, will enter retirement and shine only by the feeble glow of its aging, red stars.
NASA's Jet Propulsion Laboratory News and Features 24 Jan 2019, 16:09 UTC NASA's Opportunity rover begins its 16th year on the surface of Mars today. The rover landed in a region of the Red Planet called Meridiani Planum on Jan. 24, 2004, sending its first signal back to Earth from the surface at 9:05 p.m. PST (Jan. 25, 2004, at 12:05 a.m. EST). The golf-cart-sized rover was designed to travel 1,100 yards (1,006 meters) and operate on the Red Planet for 90 Martian days (sols). It has traveled over 28 miles (45 kilometers) and logged its 5,000th Martian day (or sol) back in February of 2018.
ALMA (Atacama Large Millimetre/Submillimetre Array) 23 Jan 2019, 21:20 UTC When astronomers discovered a cosmic explosion in a galaxy nearly 200 million light-years from Earth last June 16, they soon realized it was something different. While still debating the details, scientists now believe they may have gotten their first glimpse of the birth of a powerful phenomenon seen throughout the Universe.

Max Planck Institute for Radio Astronomy 21 Jan 2019, 08:12 UTC Including the powerful ALMA into an array of telescopes for the first time, astronomers have found that the emission from the supermassive black hole Sagittarius A* (Sgr A*) at the center of our Galaxy comes from a smaller region than previously thought. This may indicate that a radio jet from Sgr A* is pointed almost directly towards the Earth.
