A cleaner X-ray view of our galactic center's hot mess
The center of the Milky Way galaxy is a chaotic place. In addition to the 4-million-solar-mass black hole known as Sagittarius A* (Sgr A*), the region is full of gas, dust, strong magnetic fields and stars in various stages ...

Hidden star cluster discovered in Milky Way's crowded disk defies easy classification
Astronomers have discovered a stellar cluster hidden in the crowded disk of the Milky Way. The object, named Garro 04, was first identified as an unusual collection of stars in observations from the VVVX survey and was later ...
New simulations connect the first stars to cosmic fingerprints still visible today
Researchers have used some of the most detailed simulations yet of the early universe to investigate how the first stars and galaxies formed. Led by researchers at the University of Bath in the U.K., alongside collaborators ...

How NASA's Nancy Grace Roman Space Telescope will open a window into the Milky Way
Look up at the night sky with the naked eye and it may seem like it rarely changes. Yet the universe is in constant flux. Stars drift through space, orbiting the center of the Milky Way as planets orbit them. They rotate, ...

Diving into an out-of-sync galaxy
Galaxies are like snowflakes: No two are exactly alike, even the spirals. The Hubble Space Telescope took a close look at the distant spiral NGC 4693 and found intriguing hints about its past. For one thing, this member of ...

A tiny stellar system may be a 'satellite of a satellite'
Astronomers using data from the Euclid space telescope have discovered an exceptionally faint stellar system near the Fornax dwarf galaxy. Called Fornax-7, it appears to contain only about 170 times the mass of the sun in ...
Astronomers discover a radio galaxy with evidence of four separate jet outbursts
Astronomers have identified what may be the first example of a new class of radio galaxy, one whose central black hole appears to have launched powerful jets on four separate occasions. High-resolution observations with the ...
Black hole jets reach far beyond galaxies' visible edges, potentially deciding their fate
Galaxies are enormous and hold hundreds of billions of stars. These stars form from cold, dense gas. Every large galaxy, including the Milky Way, is wrapped in a huge envelope of gas called the circumgalactic medium, or CGM. ...
