Gullies on Martian sand dunes, like these in Matara Crater, have been very active, with many flows in the last ten years. The flows typically…
Astronomers using NASA’s Hubble Space Telescope have for the first time precisely measured the distance to one of the oldest objects in the universe, a…
Chemical models developed to help limit the emission of pollutants by car engines are being used to study the atmospheres of hot exoplanets orbiting close…
Astronomers have used Chandra to study a gigantic and resilient “cold front” in the Perseus galaxy cluster. This structure spans about 2 million light years,…
An international team of researchers has imaged newly forming jets of plasma from a massive black hole with unprecedented accuracy. Radio images made with a…
In the first fractions of a second after the birth of our universe, not only elementary particles and radiation, but also magnetic fields were generated….
Astronomers using the NASA/ESA Hubble Space Telescope have found the most distant star ever discovered. The hot blue star existed only 4.4 billion years after…
This image is packed full of galaxies! A keen eye can spot exquisite ellipticals and spectacular spirals, seen at various orientations: edge-on with the plane…
As part of an effort to identify distant planets hospitable to life, NASA has established a crowdsourcing project in which volunteers search telescopic images for…
The discovery of an exoplanet has most often resulted from the monitoring of a star’s flicker (the transiting method) or its wobble (the radial velocity…
The slow fade of radioactive elements following a supernova allows astrophysicists to study them at length. But the universe is packed full of flash-in-the-pan transient…
Galaxies and dark matter go together like peanut butter and jelly. You typically don’t find one without the other. Therefore, researchers were surprised when they…
Starting next year, scientists will get their first look deep below the surface of Mars. That’s when NASA will send the first robotic lander dedicated…
NASA’s Transiting Exoplanet Survey Satellite (TESS) is undergoing final preparations in Florida for its April 16 launch to find undiscovered worlds around nearby stars, providing…
Astronomers have discovered a rare “runaway” star that is speeding across its galaxy at 300,000 miles (480,000 kilometers) per hour (at that speed it would…
