Using various ground-based facilities and space telescopes, astronomers have observed an accretion outburst that recently occurred on a young variable star known as V1741 Sgr. Results of the observations, published January ...
There's an incredibly ancient black hole out there that's challenging astronomers to explain how it could exist only 400 million years after the Big Bang. It's at the heart of a galaxy called GN-z11. Astronomers using JWST ...

Using various ground-based telescopes, astronomers have performed photometric and spectroscopic observations of a nearby Type Ia supernova known as SN 2020nlb. Results of the observations campaign, presented January 16 on ...
Astronomers from Turkey and Russia have performed optical observations of a magnetic cataclysmic variable known as SRGA J213151.5+491400. Results of the observational campaign, presented Jan. 11 on the pre-print server arXiv, ...
This image features a relatively small galaxy known as UGC 5189A, which is located about 150 million light-years away in the constellation Leo. This galaxy was observed by the NASA/ESA Hubble Space Telescope to study a supernova ...

Astronomers from the Open University in Milton Keynes, UK and elsewhere report the detection of a new Be/X-ray binary. The newfound system, designated 4XMM J182531.5–144036, exhibits persistent X-ray emission. The finding ...
At the center of most large galaxies lives a supermassive black hole (SMBH). The Milky Way has Sagittarius A*, a mostly dormant SMBH whose mass is around 4.3 million times that of the sun. But if you look deeper into the ...

Astronomers have performed multiwavelength observations of a nearby M-dwarf star known as EV Lacertae (or EV Lac for short). The observational campaign resulted in the detection of a new large stellar flare from this object. ...
In summer 2022, astronomers detected the most powerful fast radio burst (FRB) ever observed. And coming from a location that dates halfway back to the Big Bang, it also was the farthest known FRB spotted to date.
