From the earliest days of our solar system's history, collisions between astronomical objects have shaped the planets and changed the course of their evolution. Studying the early bombardment history of Mars, scientists at Southwest Research Institute (SwRI) and the University of Arizona have discovered a 400-million-year lull in large impacts early in Martian history.
In order to make sense of our universe, astronomers have to work hard, and they have to push observing technology to the limit. Some of that hard work revolves around what are called sub-millimeter galaxies (SMGs.) SMGs are galaxies that can only be observed in the submillimeter range of the electromagnetic spectrum.
Lomonosov Moscow State University scientists published the results of a study of unique ultra-slow pulsar XB091D. This neutron star is believed to have captured a companion only a million years ago, and since then, has been slowly restoring its rapid rotation. Show More Summary
(Phys.org)—A team of astronomers led by Yoshiki Matsuoka of the National Astronomical Observatory of Japan (NAOJ) has detected a treasure trove of new high-redshift quasars (or quasi-stellar objects) and luminous galaxies. The newly found objects could be very important for our understanding of the early universe. Show More Summary
It's springtime and the deployed primary mirror of NASA's James Webb Space Telescope looks like a spring flower in full bloom.
In the early hours of Saturday morning, the international Cassini–Huygens mission made its final close flyby of Saturn's largest moon, Titan, coming within 1000 km of the atmosphere-clad world.
(Phys.org)—The team of researchers working on the Breakthrough Listen project (affiliated with SETI) has released preliminary findings after sifting through several petabytes of data obtained from three telescopes involved in the research project. Show More Summary
The Ring Nebula is one of the most spectacular deep-sky objects in the heavens. It is easily located by backyard astronomers, intensely studied by astrophysicists and relied upon for show-stopping images on countless book covers and calendar pages.
NASA's Cassini spacecraft has had its last close brush with Saturn's hazy moon Titan and is now beginning its final set of 22 orbits around the ringed planet.
US President Donald Trump congratulated NASA astronaut Peggy Whitson for setting a new space record on Monday, but expressed disdain for a particular rigor of space life—drinking recycled urine.
Astronaut Peggy Whitson has another record under her space belt.
New data from NASA's Cassini mission, combined with measurements from the two Voyager spacecraft and NASA's Interstellar Boundary Explorer, or IBEX, suggests that our sun and planets are surrounded by a giant, rounded system of magnetic...Show More Summary
(Phys.org)—Using the Multi Unit Spectroscopic Explorer (MUSE), astronomers have identified a new elliptical jellyfish-like galaxy in the Abell 2670 cluster. The newly detected galaxy showcases spectacular one-sided tails of gas and young stars, which indicates intense ram-pressure stripping. The findings were presented Apr. 18 in a paper published on the arXiv pre-print server.
(Phys.org)—A team of researchers with the University of Edinburgh has found what they describe as evidence of a comet striking the Earth at approximately the same time as the onset of the Younger Dryas in carvings on an ancient stone pillar in southern Turkey. The group has published their findings in the journal Mediterranean Archaeology and Archaeometry.
Cassini is the most sophisticated space probe ever built. Launched in 1997 as a joint NASA/European Space Agency mission, it took seven years to journey to Saturn. It's been orbiting the sixth planet from the sun ever since, sending back data of immense scientific value and images of magnificent beauty.
Earth is the largest rocky planet in our Solar System, and the only body we know of capable of supporting life. With so much news about exoplanets dominating the headlines, in this episode of Space we take a step back to take a look at Earth as a planet.
A globular cluster is a roughly spherical ensemble of stars (as many as several million) that are gravitationally bound together, and typically located in the outer regions of galaxies. Low mass X-ray binary stars (LMXBs) are systems in which one star is compact (a neutron star or black hole) and is accreting matter from a companion star.
A supply ship bearing John Glenn's name arrived at the International Space Station on Saturday.
An upcoming launch of a government spy satellite for the National Reconnaissance Office will mark the first time the U.S. Department of Defense has used SpaceX for a mission.
China's first cargo spacecraft, Tianzhou-1, successfully completed docking with an orbiting space lab on Saturday, the Beijing Aerospace Control Center said.
