Debris from Stellar Explosion Not Slowed After 400 Years
A new sequence of Chandra images, taken over nearly a decade and a half, captures motion in Kepler's supernova remnant. Pieces of this debris field are still moving at about 23 million miles per hour over 400 years after the explosion was spotted by early astronomers. Scientists are still trying to determine whether an extremely powerful explosion or an unusual environment around it is responsible for these high speeds so long after the explosion. The Kepler supernova was triggered by a white dwarf that reached a critical mass after interacting with a companion star and exploded.

Are we still listening to space?
When LIGO, the Laser Interferometer Gravitational-Wave Observatory, and its European counterpart, Virgo, detect a gravitational ripple from space, a public alert is sent out. That alert lets researchers know with a decently high confidence that this ripple was probably caused by an exceptional cosmic event, such as the collision of neutron stars or the merging of black holes, somewhere in the universe.

Toward an Ultrahigh Energy Density Capacitor
To make the new material, the thin film is first deposited via a pulsed-laser deposition process in this chamber. The bright “plume” you see is the laser hitting the target and depositing the material.

NASA's Webb to Study Quasars and Their Host Galaxies in Three Dimensions
Quasars—accreting supermassive black holes—are paradoxically some of the brightest objects in the universe. Astronomers widely consider the energy from quasars to be the main driver in limiting the growth of massive galaxies. Scientists plan to use Webb to study the impact of three carefully selected quasars on their host galaxies in a program called Q3D.

NASA Researchers Track Slowly Splitting 'Dent' in Earth’s Magnetic Field
This stereoscopic visualization shows a simple model of the Earth's magnetic field. The magnetic field partially shields the Earth from harmful charged particles emanating from the Sun.
