James Webb Unfolds Sunshield

James Webb Unfolds Sunshield It’s almost time. Soon the James Webb Space Telescope will be on its way to the Sun/Earth L2 Lagrange point and will begin its at least 5-year science mission. Really, it’s going to happen. Despite several delays since the program began in 1996 and a budget that has exceeded the original […]

X-rays surrounding ‘Magnificent 7’ may be traces of sought-after particle

X-rays surrounding ‘Magnificent 7’ may be traces of sought-after particle A new study, led by a theoretical physicist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars. phys.org Go to Source

NASA Has Given Up on Trying to Deploy InSight’s Mole

NASA Has Given Up on Trying to Deploy InSight’s Mole It’s always a sad day when a mission comes to an end. And it’s even sadder when the mission never really got going in the first place. That’s where we’re at with NASA’s InSight lander. The entire mission isn’t over, but the so-called Mole, the […]

Galaxies hit single, doubles, and triple (growing black holes)

Galaxies hit single, doubles, and triple (growing black holes) When three galaxies collide, what happens to the huge black holes at the centers of each? A new study using NASA’s Chandra X-ray Observatory and several other telescopes reveals new information about how many black holes are furiously growing after these galactic smash ups. phys.org Go […]

Final data release from DESI Legacy Imaging Surveys issued

Final data release from DESI Legacy Imaging Surveys issued Astronomers using images from Kitt Peak National Observatory and Cerro Tololo Inter-American Observatory have created the largest ever map of the sky, comprising over a billion galaxies. The ninth and final data release from the ambitious DESI Legacy Imaging Surveys sets the stage for a ground-breaking […]

Doubling the number of known gravitational lenses

Doubling the number of known gravitational lenses Data from the DESI (Dark Energy Spectroscopic Instrument) Legacy Imaging Surveys have revealed over 1200 new gravitational lenses, approximately doubling the number of known lenses. Discovered using machine learning trained on real data, these warped and stretched images of distant galaxies provide astronomers with a flood of new […]

NASA’s SDO spots first lunar transit of 2021

NASA’s SDO spots first lunar transit of 2021 On Jan. 13, 2021, NASA’s Solar Dynamics Observatory, or SDO, experienced its first lunar transit of the year when the moon crossed its view of the sun. The transit lasted about 30 minutes, between 12:56 and 1:25 a.m. ET. During this time, the moon happened to cover […]

Shining a new light on dark energy

Shining a new light on dark energy The Dark Energy Survey has released a massive, public collection of astronomical data and calibrated images from six years of work. Containing data on nearly 700 million astronomical objects, this second data release in the Survey’s seven-year history is the topic of sessions today and tomorrow at the […]
