A team working with ESO’s High Accuracy Radial velocity Planet Searcher (HARPS) at the La Silla Observatory in Chile has found that the red dwarf star Ross 128 is orbited by a low-mass exoplanet every 9.9 days. This Earth-sized world is expected to be temperate, with a surface temperature that may also be close to […]
An asteroid, also known as the Chicxulub Impactor, hit Earth some 66 million years ago, causing a crater 180 km wide. The impact of the asteroid heated organic matter in rocks and ejected it into the atmosphere, forming soot in the stratosphere. Soot is a strong, light-absorbing aerosol that caused global climate changes that triggered […]
On Tuesday, Nov. 7, experts from NOAA will discuss how information from JPSS-1, the first in a series of four advanced NOAA polar-orbiting satellites called the Joint Polar Satellite System, will be used by scientists to help improve weather and natural hazard forecasts in Alaska. The instruments aboard the new satellite will provide more than […]
WASHINGTON D.C. — The Chicxulub asteroid impact that wiped out the dinosaurs likely released far more climate-altering sulfur gas into the atmosphere than originally thought, according to new research. A new study makes a more refined estimate of how much sulfur and carbon dioxide gas were ejected into Earth’s atmosphere from vaporized rocks immediately after the […]
