Astronomers find hidden trove of massive black holes

A team led by researchers at the University of North Carolina at Chapel Hill has found a previously overlooked treasure trove of massive black holes in dwarf galaxies. The newly discovered black holes offer a glimpse into ...

Extraterrestrial stone brings first supernova clues to Earth

New chemistry "forensics" indicate that the stone named Hypatia from the Egyptian desert could be the first tangible evidence found on Earth of a supernova type Ia explosion. These rare supernovas are some of the most energetic ...

European astronomers discover four new brown dwarfs

Astronomers from the Astronomical Observatory of Padova, Italy, and elsewhere have conducted observations of 25 stars as part of the COPAINS Pilot Survey. As a result, they detected four new brown dwarfs that received designations ...

Hubble's double take on a spiral galaxy

The magnificent spiral galaxy M99 fills the frame in this image from the NASA/ESA Hubble Space Telescope. M99—which lies roughly 42 million light-years from Earth in the constellation Coma Berenices—is a "grand design" ...

Astronomers discover micronovae, a new kind of stellar explosion

A team of astronomers, with the help of the European Southern Observatory's Very Large Telescope (ESO's VLT), have observed a new type of stellar explosion—a micronova. These outbursts happen on the surface of certain stars, ...

Radio flares observed on a nearby M dwarf star

Using the MeerKAT radio telescope, an international team of astronomers have detected radio flares on a nearby M dwarf star known as SCR 1746−3214. The finding, reported in a paper published April 7 on the pre-print server ...

MAGIC telescopes observe nova explosion

Light on, light off—this is how one could describe the behavior of the nova, which goes by the name RS Ophiuchi (RS Oph). Every 15 years or so, a dramatic explosion occurs in the constellation of the Serpent Bearer. Birthplaces ...

New brown dwarf discovered with TESS

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new brown dwarf. The newly found object, designated TOI-2119b, turns out to be about the size of Jupiter but over ...
