Watching the Death of a Rare Giant Star

Extreme supergiant stars known as hypergiants are very rare, with only a few known to exist in the Milky Way. By tracing molecular emissions in the outflows around the red hypergiant star VY Canis ...

Dead Star's Cannibalism of Its Planetary System Is Most Far-Reaching Ever Witnessed

The violent death throes of a nearby star so thoroughly disrupted its planetary system that the dead star left behind -- known as a white dwarf -- is sucking in debris from both the system's ...

Astronomers Find Evidence for Most Powerful Pulsar in Distant Galaxy

Astronomers using data from the VLA Sky Survey have discovered one of the youngest known neutron stars -- possibly as young as only 14 years. The dense remnant of a supernova explosion was revealed ...

Astronomers Discover a Multiplanet System Nearby

Astronomers discovered a multiplanet system just 33 light-years from Earth, making it one of the closest known multiplanet systems. The system likely hosts at least two terrestrial, Earth-sized ...

Astronomers have mapped the surface properties of the asteroid Psyche, revealing a landscape of metal and ...

The Tarantula's Cosmic Web: Astronomers Map Violent Star Formation in Nebula Outside Our Galaxy

Astronomers have unveiled intricate details of the star-forming region 30 Doradus, also known as the Tarantula Nebula, using new observations from the Atacama Large Millimeter/submillimeter Array ...

To Find a Planet, Look for the Signatures of Planet Formation

Finding forming planets is a tough but important job for astronomers: Only three planets have ever been discovered caught in the process of forming, and the most recent of these was found just weeks ...

Previously Hidden Protoclusters Could Reveal New Details of Galaxy Evolution

The ancestors of some of the largest galaxy clusters have been hiding in plain sight. New work demonstrates a new technique for identifying the precursors of the most extreme galactic ...

NASA Telescope to Help Untangle Galaxy Growth, Dark Matter Makeup

NASA's Nancy Grace Roman Space Telescope will study wispy streams of stars that extend far beyond the apparent edges of many galaxies. Missions like the Hubble and James Webb space telescopes ...

Scientists on the Hunt for Planetary Formation Fossils Reveal Unexpected Eccentricities in Nearby Debris Disk

Astronomers have imaged the debris disk of the nearby star HD 53143 at millimeter wavelengths for the first time, and it looks nothing like they expected. Based on early coronagraphic data, ...

Young Galaxy’s Coming of Age: Early Galaxies May Be Surprisingly Big and Complex

Scientists have observed a significant amount of cold, neutral gas in the outer regions of the young galaxy A1689-zD1, as well as outflows of hot gas coming from the galaxy's center. These ...

A Weird Star Produced the Fastest Nova on Record

A research team has observed the fastest nova ever. They hope to find answers to not only the nova's many baffling traits, but to larger questions about our solar system and the ...
