New Method May Resolve Difficulty in Measuring Universe's Expansion

National Radio Astronomy Observatory

Radio telescope observations have made it possible for astronomers to use mergers of neutron-star pairs as a valuable new tool for measuring the Universe's expansion.

Planetary Rings of Uranus ‘Glow’ in Cold Light

National Radio Astronomy Observatory

Summary: Using the both ALMA and the VLT, astronomers have imaged the cold, rock-strewn rings encircling the planet Uranus. Rather than observing the reflected sunlight from these rings, ALMA and the VLT imaged the millimeter and mid-infrared “glow” naturally emitted by the frigidly cold particles of the rings themselves.

Black Hole's Tug on Space Pulls Fast-Moving Jets in Rapid Wobble

National Radio Astronomy Observatory

A spinning black hole pulls in material from a companion star, and its gravitational effect causes ejected jets of material to wobble like a child's spinning top.

EHT Radio Astronomy Newsroom

National Radio Astronomy Observatory

The first direct visual evidence of a black hole will help scientists understand how the universe behaves under conditions of extreme gravity, forces so strong that they warp the fabric of space and time.

VLA Makes First Direct Image of Key Feature of Powerful Radio Galaxies

National Radio Astronomy Observatory

A dusty, doughnut-shaped feature, long thought an essential part of the "engines" of active galaxies, is found in one of the most powerful galaxies in the Universe.

Astronomers Find 'Cannonball Pulsar' Speeding Through Space

National Radio Astronomy Observatory

Astronomers using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) have found a pulsar speeding away from its presumed birthplace at nearly 700 miles per second, with its trail pointing directly back at the center of a shell of debris from the supernova explosion that created it. The discovery is providing important insights into how pulsars — superdense neutron stars left over after a massive star explodes — can get a “kick” of speed from the explosion.

Liberal Sprinkling of Salt Discovered Around a Young Star

National Radio Astronomy Observatory

New ALMA observations show there is ordinary table salt in a not-so-ordinary location: 1,500 light-years from Earth in the disk surrounding a massive young star.
