One of the new high-resolution simulations of the dark matter enveloping the Milky Way and its neighbor, the Andromeda galaxy. The new study shows that…
Astronomers from Rice University and other organizations dug deep into the data from this near-infrared image, one of the first taken by NASA’s James Webb…
A disk of hot gas swirls around a black hole in this illustration. The stream of gas stretching to the right is what remains of…
This infrared image of the Orion Nebula features plenty of dust but no stars. In these infrared wavelengths, it’s possible to see hot spots where…
Astrophysicists have devised a new way to verify the existence of the supermassive black hole Leo I*. A behemoth black holeA black hole is a…
How it works: Using trial and error, machine learning tests many different pairings of simulated galaxies and black holes created using different rules, and then…
The new work extends models from nuclear physics. A new model for matter in neutron star collisions. After a massive star burns its fuel and…
An artist’s concept of the Kepler-1658 system. Kepler-1658b, orbiting with a period of just 3.8 days, was the first exoplanet candidate discovered by Kepler. Credit:…
Image of the Cosmic Cliffs, a region at the edge of a gigantic, gaseous cavity within NGC 3324, captured by Webb’s Near-Infrared Camera (NIRCam). This…

Scientists conducted ultra-hot experiments at the Relativistic Heavy Ion Collider, recreating temperatures not seen since the Big Bang. The unexpected results stunned physicists. A temperature…
Illustration of Saturn and its rings. All of the outer gas giant planets — Jupiter, Saturn, Neptune, and Uranus — have rings around them. Planets…
The new paper argues that the widely accepted theory from astrophysicist Brandon Carter used faulty logic. According to a recent paper by a math professor…
