The universe we live in is a transparent one, where light from stars and galaxies shines bright against a clear, dark backdrop. But this wasn't always the case—in its early years, the universe was filled with a fog of hydrogen ...
An international team of astronomers has performed high-cadence optical monitoring of an active galaxy known as Markarian 1018. Results of the observational campaign, published July 26 on the pre-print server arXiv, shed ...
A new image of the galaxy cluster known as "El Gordo" is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image, taken by NASA's James Webb Space Telescope, displays ...
The tranquil spiral galaxy UGC 12295 basks leisurely in this image from the NASA/ESA Hubble Space Telescope. This galaxy lies around 192 million light-years away in the constellation Pisces and is almost face-on when viewed ...
Astronomers from Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences and their collaborators have found five Green Pea (GP) galaxies with double-peaked narrow lines among nearly 1,550 GP galaxies. ...
When theoretical physicists like myself say that we're studying why the universe exists, we sound like philosophers. But new data collected by researchers using Japan's Subaru telescope has revealed insights into that very ...
Using the Gran Telescopio Canarias (GTC), astronomers have performed optical imaging observations of an isolated ultra-thin galaxy known as UGC 11859. Results of the observational campaign, published July 12 in The Astrophysical ...
Galaxies grow and evolve over billions of years by absorbing nearby companions and merging with other galaxies. The early stages of this galactic growth process are showcased in a new image taken with the US Department of ...
By analyzing the data from the JWST Advanced Deep Extragalactic Survey (JADES), an international team of astronomers has discovered a new quiescent galaxy. The newfound system, designated JADES-GS+53.12365-27.80454, turns ...
The irregular galaxy Arp 263 lurks in the background of this image from the NASA/ESA Hubble Space Telescope, but the view is dominated by a stellar photobomber, the bright star BD+17 2217. Arp 263—also known as NGC 3239—is ...
