Featured Image: How Do Supermassive Black Holes Eat?
New high-resolution three-dimensional simulations explore the nature of accretion onto supermassive black holes in elliptical galaxies.
Featured Image: Detecting Dust in the Local Universe
Maps of nearby galaxies using data from the Herschel Space Telescope give researchers a new perspective on dust evolution.
Featured Image: A Neutron Star Collision
Researchers use complex fluid dynamics models to understand what happens when neutron stars — the ultra-dense remnants of massive stars — meet in a catastrophic collision.
Featured Image: Making the First Stars in Spinning Clouds
Researchers use simulations to explore the possible masses of the first stars in the universe — which may determine whether those stars are still present in the universe today.
Featured Image: Two Young Star Clusters in the Milky Way
Researchers track down a pair of metal-poor star clusters on the outskirts of the Milky Way to understand how metallicity affects the masses of young stars.
Featured Image: Outflows from the Silver Coin Galaxy
About 11 million light-years away, the starburst galaxy NGC 253 spews gas into circumgalactic space. What can X-ray observations tell us about this star-forming system?
Featured Image: Re-tuning Our Understanding of the Guitar Nebula
A fast-moving pulsar has created a spectacular guitar-shaped wake that astronomers have been studying for more than 25 years.
Featured Image: Considering Craters on Uranus’s Moon Miranda
Icy solar system moons typically have sharp, well-defined craters, but Uranus’s moon Miranda has gentler surface features. What makes Miranda’s craters so subtle?
Featured Image: A Plasma-Producing Pulsar
New simulations explore plasma production and particle acceleration near the surface of a dense, highly magnetized pulsar.
