A ‘super-puff’ planet like no other

A ‘super-puff’ planet like no other The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal have found. phys.org Go to Source

Astronomers find planetary system with gas giant exoplanet and white dwarf companion

Astronomers find planetary system with gas giant exoplanet and white dwarf companion Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an interesting extrasolar planetary system consisting of a K-dwarf host star, a Jupiter-sized planet and a white dwarf. The finding and parameters of the system, designated TOI-1259, were presented […]

Cosmic beasts and where to find them

Cosmic beasts and where to find them Two giant radio galaxies have been discovered with South Africa’s powerful MeerKAT telescope. These galaxies are thought to be amongst the largest single objects in the Universe. The discovery has been published today in Monthly Notices of the Royal Astronomical Society . phys.org Go to Source

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 […]
