First-of-its-kind measurement of the Universe’s expansion rate weighs in on a longstanding debate in physics and astronomy
A University of Minnesota Twin Cities-led team used a first-of-its-kind technique to measure the expansion rate of the Universe, providing insight that could help more accurately determine the Universe’s age and help physicists and astronomers better understand the cosmos.
Astronomers find distant gas clouds with leftovers of the first stars
Using ESO’s Very Large Telescope (VLT), researchers have found for the first time the fingerprints left by the explosion of the first stars in the Universe. They detected three distant gas clouds whose chemical composition matches what we expect from the first stellar explosions.
Deep-Space Discovery: Oddball Gamma-Ray Burst Forces Revision of Theoretical Framework
In the Dec. 7 issue of the journal Nature, an international team of astrophysicists report the discovery of a unique cosmological gamma-ray burst (GRB) that defies prevailing theories of how the violent cosmic explosions form.
Red Alert: massive stars sound warning they are about to go supernova
Astronomers from Liverpool John Moores University and the University of Montpellier have devised an ‘early warning’ system to sound the alert when a massive star is about to end its life in a supernova explosion.
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. It was revealed when bright radio emission emerged from behind a thick shell of explosion debris.
Gigantic Cavity in Space Sheds New Light on How Stars Form
Astronomers have discovered a humongous cavity in space while mapping interstellar dust. The sphere-shaped phenomenon may explain how supernovae lead to star formation.
James Kneller: Then and Now / 2011 Early Career Award Winner
At North Carolina State University, associate professor James Kneller studies neutrinos emitted from exploding stars.
Rutgers Expert Available to Discuss Supernova Discovery
New Brunswick, N.J. (April 21, 2021) – Rutgers University–New Brunswick astrophysicist John P. (Jack) Hughes is available for interviews on a supernova (exploding star) discovery published today in the journal Nature. The discovery, made with NASA’s Chandra X-ray Observatory, features…
Rutgers Expert Available to Discuss James Webb Space Telescope Science
New Brunswick, N.J. (Feb. 22, 2021) – Rutgers University–New Brunswick Professor Kristen McQuinn is available for interviews on the upcoming launch of the James Webb Space Telescope, its potential scientific impact and the leap forward it will provide in our understanding of the…
FSU COMPUTATIONAL SCIENTIST DEMONSTRATES HOW SUPERNOVAE DETONATE
The mystery of how supernovae fully form and function is one of many secrets of the universe that scientists have yet to unravel, but new work by a Florida State University research team has used theory and computations to show how one class of these luminous stellar explosions go from a slow burn to a brilliant detonation.
New NSF Physics Frontier Center Will Focus on Neutron Star Modeling in ‘Gravitational Wave Era’
A new Physics Frontier Center at UC Berkeley, supported by the National Science Foundation, expands the reach and depth of existing capabilities on campus and at neighboring Berkeley Lab in modeling one of the most violent events in the universe: the merger of neutron stars and its explosive aftermath.
This Supernova in a Lab Mimics the Cosmic Blast’s Splendid Aftermath
(Study publishes 6/17/20. No embargo.) Mystery enshrouds the birth of swirls typical for supernova remnants like the Crab Nebula. A new “supernova machine” may help solve it.
Astronomers Discover New Class of Cosmic Explosions
Analysis of two cosmic explosions indicates to astronomers that the pair, along with a puzzling blast from 2018, constitute a new type of event, with similarities to some supernovae and gamma-ray bursts, but also with significant differences.
Large Amounts of Oxygen Detected in Ancient Star’s Atmosphere
An international team of astronomers from the University of California San Diego, the Instituto de Astrofísica de Canarias (IAC) and the University of Cambridge have detected large amounts of oxygen in the atmosphere of one of the oldest and most elementally depleted stars known—a primitive star scientists call “J0815+4729.”
