Hubble Gamma Ray Burst
These images taken by NASA’s Hubble Space Telescope reveal a new type of stellar explosion produced by the merger of two compact objects: either two neutron stars or a neutron star and a black hole. The galaxy in the center of the left image produced the gamma-ray burst, whose lingering effects were visible on June 13 but had faded by July 3. [Read the Full Story]

Kilonova Explosion: Sequence of Events
This sequence illustrates a model for the formation of a short-duration gamma-ray burst to become a powerful kilonova explosion. Here, two neutron stars circle one another and ultimately collide to kick out highly radioactive material. This material heats up and expands, emitting a burst of light called a kilonova. An accompanying gamma-ray burst lasts just one-tenth of a second, but is 100 billion times brighter than the kilonova flash. Image released Aug. 3, 2013. [Read the Full Story]
Kilonova Explosion: Step 1
In this illustration, two ultradense neutron stars circle one another, slowly coming together in the first step toward a cosmic collision that can create a kilonova gamma-ray burst. Image released Aug. 3, 2013. [Read the Full Story]

Two ultradense neutron stars collide to unleash a kilonova gamma-ray burst explosion in this artist's illustration. Image released Aug. 3, 2013. [Read the Full Story]
Kilonova Gamma-Ray Burst Explosion
Two ultradense neutron stars explode in a powerful, but just millisecond-brief, gamma-ray burst to spark a kilonova event in this artist's illustration. Image released Aug. 3, 2013. [Read the Full Story]
Kilonova Aftermath: Illustration
A remnant disk of debris surrounds the merged remains of two ultradense neutron stars in a kilonova gamma-ray burst, which may have collapsed to form a black hole. Image released Aug. 3, 2013. [Read the Full Story]
