This Binary System is Destined to Become a Kilonova
Kilonovae are extraordinarily rare. Astronomers think there are only about 10 of them in the Milky Way. But they're extraordinarily…
By Looking Back Through Hubble Data, Astronomers Have Identified six Massive Stars Before They Exploded as Core-Collapse Supernovae
Using images from the Hubble Snapshot Program and archival data, a team of astronomers has located the progenitor stars of…
Hubble saw the Same Supernova at Three Different Times Thanks to Gravitational Lensing
As cosmic events go, supernova explosions epitomize the saying, "Live fast, die young, and leave a good-looking corpse." They're the…
Hubble saw Multiple Light Echoes Reflecting off Rings of Dust From a Supernova Explosion
Using images from Hubble, an international team of astronomers created a video that shows the evolution of a supernova and…
How Dangerous are Nearby Supernovae to Life on Earth?
Life and supernovae don't mix. From a distance, supernovae explosions are fascinating. A star more massive than our Sun runs…
Can Astronomers Predict Which Stars Are About to Explode as Supernovae?
In a recent study submitted to High Energy Astrophysical Phenomena, a team of researchers from Japan discuss strategies to observe,…
Recent Supernovae Produced Giant Cavities in the Orion Nebula
The Orion Nebula is a well-known feature in the night sky and is visible in small backyard telescopes. Orion is…
Do Ancient Coins Record the Supernova of 1054?
SN 1054 was one of the most spectacular astronomical events of all time. The supernova explosion eventually formed what is…
Hubble Sees a Surviving Companion Star After its Partner Went Supernova
When stars die they’re often not alone, and for the first time astronomers have found a companion to a supernova,…
We can Probably Find Supernovae Enhanced by Gravitational Lensing, We Just Need to Look
Gravitational lensing provides an opportunity to see supernovae and other transients much farther than we normally can. A new research…
