Thousands of new astronomical images highlighted in latest release of AAS WorldWide Telescope
Feb 16, 2022 (SPX)
WWT isn't a physical telescope, but rather a suite of free and open-source software that integrates data and images from dozens of astronomical observatories an...
NASA's IXPE sends first science image
Feb 15, 2022 (SPX)
IXPE first focused its X-ray eyes on Cassiopeia A, an object consisting of the remains of a star that exploded in the 17th century. The shock waves from the exp...
UCI scientists discover how galaxies can exist without dark matter
Feb 15, 2022 (SPX)
It's a mechanism that has the potential to explain how galaxies might be able to exist without dark matter - something once thought impossible. It started in 20...
Astronomers discover a new type of star covered in helium burning ashes
Feb 15, 2022 (SPX)
While normal stars have surfaces composed of hydrogen and helium, the stars discovered by Werner and his colleagues have their surfaces covered with carbon and ...
Photons received: Webb sees its first star 18 times
Feb 11, 2022 (SPX)
The team's challenge was twofold: confirm that NIRCam was ready to collect light from celestial objects, and then identify starlight from the same star in each ...
Webb telescope spots its first star -- and takes a selfie
Feb 11, 2022 (AFP)
The steps are part of the months-long process of aligning the observatory's enormous golden mirror that astronomers hope will begin unraveling the mysteries of ...
Webb sees its first star - 18 times
Feb 11, 2022 (ESA)

Webb Is Chilling Out
Feb 11, 2022 (SPX)
Webb's giant sunshield keeps the telescope and cameras out of both direct sunlight and sunlight that is reflected from Earth and the Moon. Everything on the col...
Hubble Views a Cosmic Interaction
Feb 11, 2022 (SPX)
If the image revealed the full emission of both AGNs, their brilliance would obscure the beautifully detailed tidal interactions we see in this image. Tidal for...
New Tool Launches for Astronomy Software Users
Feb 10, 2022 (SPX)
Astronomers rely on scientific software to analyze data sets and model complex astrophysical objects and phenomena. But as the collection of astronomy-related s...
Surprisingly high fraction of dead galaxies found in ancient galactic city
Feb 10, 2022 (SPX)
Galaxy clusters grow over time under gravity and, in the present-day universe, can contain hundreds or even thousands of galaxies, as well as hot gas and dark m...
The Magnetic Field in Milky Way Bones
Feb 09, 2022 (SPX)
While most of the key physical properties of these bones are known, what we know of their magnetic field properties is generally unconstrained. These fields can...
For clues to neutron stars, scientists probe lead nuclei's thin neutron skin
Feb 09, 2022 (SPX)
These extra neutrons tend to stick to the outer edges of heavy nuclei and form a kind of neutron-rich "skin" around a more evenly distributed core. A recent exp...
Chemical history of the Milky Way revealed by new catalog of tens of millions of stars
Feb 08, 2022 (SPX)
