A New View of Exoplanets With NASA's Upcoming Webb Telescope
May 30, 2019 (SPX)
Exoplanets are close to much brighter stars, so their light is generally overwhelmed by the light of the host stars. Astronomers usually find an exoplanet by in...
Evidence of New Magnetic Transitions in Sun-like Stars from Gaia Data
May 28, 2019 (SPX)
Multiple observations of the same star, required to derive its distance and motion, also produced parameters related to stellar variability. Data for stars with...
Nature inspires a novel new form of computing, using light
May 27, 2019 (SPX)
The material in the cube reads and reacts intuitively to the light in much the same way a plant would turn to the sun, or a cuttlefish would change the color of...
Chemistry of stars sheds new light on the Gaia Sausage
May 24, 2019 (SPX)
Astrophysicists at the University of Birmingham in collaboration with colleagues at European institutions in Aarhus, Bologna and Trieste, have been studying evi...
Young stars heat molecular clouds and drive gas bubbles throughout galaxies
May 23, 2019 (SPX)
Based on new observations of the NGC 300 spiral galaxy, a team of scientists led by astrophysicist Dr Diederik Kruijssen from Heidelberg University has now mana...

May 22, 2019 (SPX)
The extremely rare merger product was discovered by scientists from the University of Moscow. On images made by the Wide-field Infrared Survey Explorer (WISE) s...
Giant Telescope on Sea Floor Will Study Neutrinos from Space
May 22, 2019 (SPX)
Located at two sites at depths of up to 3,500 meters, the KM3NeT telescope will occupy more than a cubic kilometre of water, and will comprise of hundreds of ve...
CosmoGAN: Training a neural network to study dark matter
May 21, 2019 (SPX)
Toward this end, gravitational lensing is one of the most promising tools scientists have to extract this information by giving them the ability to probe both t...
Astronomers find white dwarf merger that may spawn future fiery explosion
May 21, 2019 (UPI)
According to a new paper describing the unusual stellar object, published this week in the journal Nature, the orb is a ticking time bomb -- likely to explode w...
ALMA Discovers Aluminum Around Young Star
May 17, 2019 (SPX)
Young stars are surrounded by disks of gas. Some of the gas condenses into dust grains which then stick together to form larger objects, building up to form met...
Galaxy Blazes with New Stars Born from Close Encounter
May 17, 2019 (SPX)
The right side of the galaxy is ablaze with star formation, shown in the plethora of young blue stars and star-incubating pinkish nebulas. The left side, howeve...
10 years ago, Hubble's final servicing mission made it better than ever
May 14, 2019 (SPX)
He had stripped the bottom right screw. It wouldn't budge. "I saw what I had done and my heart just sank," Massimino recalled. That day, Massimino and fellow as...
Our history in the stars
May 13, 2019 (SPX)
