Axions may be responsible for an excess of X-ray emissions coming from a group of neutron stars in our galaxy.

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. This intriguing discovery by Ph.D. student Caroline Piaulet of Ude

The Milky Way houses 8,292 recently discovered stellar streams—all named Theia. But Theia 456 is special.

The newly discovered black hole is more like Old Faithful geyser at Yellowstone National Park, erupting repeatedly at predictable times.

Here's what NASA have planned for 2021.

Salt Lake City UT (SPX) Jan 07, 2021 - Utah State University's Space Dynamics Laboratory announced that it has successfully completed the Key Decision Point (KDP) C for NASA's Atmospheric Waves Experiment (AWE). KDP-C provides NASA appro

From an observatory high above Chile's Atacama Desert, astronomers have taken a new look at the oldest light in the universe.

The definition of a star is as rich and colorful as, well, the stars themselves.

The governor of Puerto Rico says she backs rebuilding the Arecibo radio observatory, but a final decision regarding reconstructing it could take years.

The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study of black holes that could have formed in the early univers

Multi-messenger astronomy allows researchers to put new constraints on the radius of a typical neutron star and provide a novel calculation of the Hubble constant.

A new technique may sift out universe's very first gravitational waves. Identifying primordial ripples would be key to understanding conditions of the early universe.

A phenomenon first detected in the solar wind may help solve a long-standing mystery about the sun: why the solar atmosphere is millions of degrees hotter than the surface. Images from the Earth-orbiting Interface Region Imaging Spectrograph, aka IRIS, and the Atmospheric Imaging Assembly, aka AIA, show evidence that low-lying magnetic loops are heated to […]

A FIREBALL boomed over the southern US and northern Mexico, leaving onlookers stunned by the sighting.

Celestial reference frames built from Gaia star-mapping satellite promise better planetary navigation and telescope pointing

It lies 6,300 light-years away in the constellation Hercules. Now, we finally know its story.

Look up at the night sky and, if you're away from city lights, you'll see stars. The space between those bright points of light is, of course,

It's one of the big cosmology debates: The universe is expanding, but how fast exactly? Two available measurements yield different results. Leiden physicist David Harvey adapted an independent third measurement method using the light warping properties of galaxies predicted by Einstein. He published his findings in the Monthly Notices of the Royal Astronomical Society.

A recent study by an international team of scientists shows that the Universe is getting hotter (not cooler) with time!

Dr Diederik Kruijssen from the University of Heidelberg said: 'The collision with Kraken must have been the most significant merger the Milky Way ever experienced.'
