NASA's Goddard Space Flight Center 27 Apr 2020, 15:00 UTC For the first time, NASA’s Neil Gehrels Swift Observatory tracked water loss from an interstellar comet as it approached and rounded the Sun. The object, 2I/Borisov, traveled through the solar system in late 2019.
Hubble Space Telescope News 24 Apr 2020, 11:00 UTC On 24 April 1990 the Hubble Space Telescope was launched aboard the space shuttle Discovery, along with a five-astronaut crew. Deployed into low-Earth orbit a day later, the telescope has since opened a new eye onto the cosmos that has been transformative for our civilization.
NASA's Chandra X-ray Observatory 23 Apr 2020, 18:19 UTC Data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton indicate that a star survived a close call with a black hole, as described in our latest press release. As a red giant star approached a supermassive black hole in the galaxy GSN 069, it was caught in the black hole's gravity.
ESA Top News 22 Apr 2020, 07:20 UTC Today marks the 50th anniversary of Earth Day. For Earth-observing satellites, every day is Earth Day. While news of COVID-19 dominates headlines and many of us practice social distancing, there still remains the need for action on climate change – and satellites are vital in providing the key facts on this global issue.
NASA's Goddard Space Flight Center 21 Apr 2020, 15:55 UTC Earth can sometimes feel like the last place you’d want to be. Indeed, a number of explorers have devised inventive ways to move civilization off this planet. It’s no surprise: The promise of a better life in the mysterious beyond can be seductive. But the fact is the more we learn about out there the more we realize how special it is here. The first astronauts to look from space back at Earth, a “pale blue dot, the only home we've ever known,” as scientist Carl Sagan once wrote, saw a beautiful, delicate world that is perfectly suited to the bounty of life it supports.
Hubble Space Telescope News 20 Apr 2020, 19:00 UTC The object was previously believed to be a planet, called Fomalhaut b, and was first announced in 2008 based on data taken in 2004 and 2006. It was clearly visible in several years of Hubble observations that revealed it as a moving dot. Unlike other directly imaged exoplanets, nagging puzzles with Fomalhaut b arose early on. The object was unusually bright in visible light, but did not have any detectable infrared heat signature.
NASA's Goddard Space Flight Center 20 Apr 2020, 14:00 UTC NASA’s Wide Field Infrared Survey Telescope (WFIRST), planned for launch in the mid-2020s, will create enormous cosmic panoramas. Using them, astronomers will explore everything from our solar system to the edge of the observable universe, including planets throughout our galaxy and the nature of dark energy.
American Astronomical Society 17 Apr 2020, 22:57 UTC Magnetized neutron stars in distant globular clusters are a challenge to detect — but it’s a job made easier by the world’s largest filled-aperture radio telescope. Recent high-sensitivity observations have uncovered an erratic new star system.
