Distant galaxies, interacting galaxies, whose shape has been forged by the mutual gravitational influence, but also galaxies forming groups and clusters, kept together by gravity—they are the protagonists of three new images ...
Bright, starry spiral arms surround an active galactic center in this new NASA Hubble Space Telescope image of the galaxy NGC 4951.
Scientific evidence for dark matter comes from observing how it influences the motion of stars and galaxies. Scientists believe that dark matter may consist of particles. To search for these particles and their billiard ball-like ...
Astronomers have discovered black holes ranging from a few times the sun's mass to tens of billions. Now a group of scientists has predicted that NASA's Nancy Grace Roman Space Telescope could find a class of "featherweight" ...
Ever wonder what happens when you fall into a black hole? Now, thanks to a new, immersive visualization produced on a NASA supercomputer, viewers can plunge into the event horizon, a black hole's point of no return.
Primordial black holes are hypothetical objects formed during the earliest moments of the universe. According to the models, they formed from micro-fluctuations in matter density and spacetime to become sand grain-sized mountain-massed ...
MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe's infancy, are revealing clues ...
Planetary scientists at the University of Colorado Boulder have discovered how Venus, Earth's scalding and uninhabitable neighbor, became so dry.
An international team of researchers led by astronomers from Leiden University (Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed ...
Dead stars known as white dwarfs, have a mass like the sun while being similar in size to Earth. They are common in our galaxy, as 97% of stars will eventually become white dwarfs. As stars reach the end of their lives, their ...
