Primordial black holes (PBHs) don't exist as far as we know. But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and they may even make up dark matter. That's ...
Dark matter could be a type of matter in the universe that does not emit, absorb or reflect detectable light and appears to interact very weakly with regular matter. Although physicists have observed gravitational effects ...
Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 "bulgeless" galaxies—systems with little or no central ...
Neutron stars, the extremely dense remains of massive stars that exploded at the end of their lives, are widely studied astrophysical objects. Some of these stars, known as pulsars, spin and send out beams of radio waves, ...
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 ...
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 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 ...
Astronomers have discovered a faint population of young stars extending far beyond the known edge of the nearby spiral galaxy Messier 74. The finding suggests the galaxy is nearly twice as large as previously measured. The ...
Exoplanets are exotic worlds orbiting distant stars far beyond our solar system. Ever since the first ones were discovered in the 1990s, astronomers have turned their attention to these distant worlds to understand more about ...
In this Picture of the Month from the NASA/ESA James Webb Space Telescope, we visit a turbulent cauldron of star formation to see what is brewing inside dense clumps of gas. This is a star-forming region named LHA 120-N 159, ...
