Subsurface radar observations acquired by NASA’s Perseverance rover inside Jezero Crater have revealed a previously unknown buried river-delta system beneath the western fan deposits of…

Supernova remnants preserve the physical record of stellar explosions long after the original event fades from view. They trace the interaction between expanding shock waves…

The ringed planet Saturn changes slowly. Its seasons stretch across decades. Its storms can last for years. Even its most famous atmospheric structures remain stable…

Supermassive black holes dominate the centers of massive galaxies and regulate their evolution through sustained accretion and energetic feedback. Observations over the last two decades…

Astronomers have identified two accreting giant planets embedded within the protoplanetary disk surrounding the young star WISPIT 2 using high-contrast imaging and long-baseline interferometry at…

For nearly a thousand years, the Crab Nebula has expanded slowly across space. Astronomers have studied it for centuries. Yet very recently, we can clearly…

A new spectroscopic view of the nearby spiral galaxy Messier 33 (Triangulum Galaxy) shows how modern integral-field instruments transform galaxy imaging into quantitative physical mapping….

Astronomers investigating the earliest phases of chemical enrichment in nearby dwarf galaxies have identified one of the most ancient stars known beyond the Milky Way….

Astronomers continue to revisit nearby galaxies with modern instruments to understand how stars, gas, and dust shape galactic evolution. One of the latest examples focuses…

Over the past decade, improvements in radio interferometry and data processing have enabled surveys with unprecedented sensitivity and resolution. One of the most ambitious projects…
