Get Ready for the 2018 Geminid Meteors

Get Ready for the 2018 Geminid Meteors When it comes to meteor showers, the calendar year always seems to save the best for last. We’re referring to the Geminid meteor shower, one of the sure fire bets for dependable meteor showers. In fact, in recent years, the Geminids have been upstaging that other yearly favorite: […]

OSIRIS-REx Has Already Found Water on Bennu

OSIRIS-REx Has Already Found Water on Bennu NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) has found water on the asteroid Bennu. Bennu is OSIRIS-REx’s only target, and though the spacecraft arrived at the asteroid on December 3rd, some of its instruments have been trained on the asteroid since mid-August. And two of those […]

Calibrating cosmic mile markers

Calibrating cosmic mile markers New work from the Carnegie Supernova Project provides the best-yet calibrations for using type Ia supernovae to measure cosmic distances, which has implications for our understanding of how fast the universe is expanding and the role dark energy may play in driving this process. Led by Carnegie astronomer Chris Burns, the […]

Cataclysmic variable ES Ceti has an accretion disk, study suggests

Cataclysmic variable ES Ceti has an accretion disk, study suggests Astronomers have conducted spectroscopic observations of the cataclysmic variable ES Ceti, which resulted in uncovering important insights about gas emission from this object. The new findings, presented in a paper published November 29 on the arXiv pre-print server, suggest the presence of an accretion disk […]

InSight’s Robot Arm is Ready to go to Work

InSight’s Robot Arm is Ready to go to Work Some new images sent home by the InSight Lander show the robotic arm and the craft’s instruments waiting on deck, on the surface of Mars. The lander is still having its systems tested, and isn’t quite ready to get to work. It’ll use its arm to […]

It’s morning, just before dawn, and a dense fog has settled along the coast. As the chill grips […]

Ice loss in Greenland is Accelerating

Ice loss in Greenland is Accelerating The rate at which Greenland is losing its ice is accelerating. This unsurprising conclusion comes from a new study based on 25 years of satellite data from the European Space Agency. The new study was published in Earth and Planetary Science Letters. The study is called 25 years of […]

An exoplanet loses its atmosphere in the form of a tail

An exoplanet loses its atmosphere in the form of a tail A new study led by scientists from the Instituto de Astrofísica de Canarias (IAC) reveals that the giant exoplanet WASP-69b carries a comet-like tail made up of helium particles escaping from its gravitational field and propelled by the ultraviolet radiation of its star. The […]

LIGO supercomputer upgrade will speed up groundbreaking astrophysics research

LIGO supercomputer upgrade will speed up groundbreaking astrophysics research In 2016, an international team of scientists found definitive evidence—tiny ripples in space known as gravitational waves—to support one of the last remaining untested predictions of Einstein’s theory of general relativity. The team used the Laser Interferometer Gravitational-Wave Observatory (LIGO), which has since made several gravitational […]
