The Aftermath of a Neutron Star Collision Resembles the Conditions in the Early Universe
Neutron stars are extraordinarily dense objects, the densest in the Universe. They pack a lot of matter into a small…
Could We Live Without Kilonovae?
It’s a classic statement shared at many public outreach events…’we are made of stardust’. It is true enough that the…
How Dangerous are Kilonovae?
Neutron stars' collisions create powerful explosions, a type of gamma-ray burst known as a kilonova. What would it be like…
JWST Confirms the Formation of Heavy Elements in a Kilonova
A recent study published in Nature investigates recent observations from NASA’s James Webb Space Telescope (JWST) and ground-based telescopes of…
How Close is Too Close to a Kilonova?
Cataclysmic events happen in the Universe all the time. Black hole mergers, supernovae, gamma-ray bursts, and a whole host of…
A Kilonova Simulated in 3D
In 2017, astronomers detected gravitational waves from colliding neutron stars for the first time: a kilonova. Enormous amounts of heavy…
Colliding Neutron Stars Could Help Measure the Expansion of the Universe
A new study presents a novel and independent method for measuring cosmic expansion using kilonova
The Expanding Debris Cloud From the Kilonova Tells the Story of What Happens When Neutron Stars Collide
When two neutron stars collide, it creates a kilonova. The event causes both gravitational waves and emissions of electromagnetic energy.…
New Simulation Shows Exactly What’s Happening as Neutron Stars Merge
Neutron stars are the remnants of massive stars that explode as supernovae at the end of their fusion lives. They're…
It’s still possible to detect the site of the 2017 kilonova explosion
It's been over a thousand days since the historic kilonova observation, and yet the region continues to emit X-rays, long…
