Scientists have long known that certain ingredients are needed to support life, especially water and key organic chemicals like carbon. In recent years, both ingredients have been found on giant asteroids and other celestial bodies. But, until now, no study had delivered conclusive evidence, based on extraterrestrial samples, to show how and when organic matter was made on the rocks that g

Surprisingly, exposure to a high background radiation might actually lead to clear beneficial health effects in humans, according to Ben-Gurion University of the Negev and Nuclear Research Center Negev (NRCN) scientists. This is the first large-scale study which examines the two major sources of background radiation (terrestrial radiation and cosmic radiation), covering the entire U.S. populatio

Humanity will mark the 60th anniversary of its first foray into space next month, with over 560 people from 41 countries reaching low Earth orbit, travelling beyond low Earth orbit, or even going to the Moon since cosmonaut Yuri Gagarin's historic 12 April, 1961 flight. Cardiovascular disease was is the single most common cause of death among Soviet and Russian cosmonauts, a comprehensive

BlackSky has announced that its latest Gen-2 satellite, BlackSky 7, delivered first insights within 24 hours of launch. Within that time frame, the BlackSky operations team conducted satellite checkout and the satellite collected its first images. At the same time, those images were downlinked, processed and analyzed using BlackSky's Spectra AI suite of AI/ML algorithms to detect objects of inte

The U.S. Space Force's Space and Missile Systems Center successfully delivered the fifth Space Based Infrared System satellite (SBIRS GEO-5) to the processing facility at Cape Canaveral Space Force Station, Florida. The satellite traveled across the country from the Lockheed Martin Space Systems Center satellite integration facility in Sunnyvale, California via a C-5M Super Galaxy on March

Astronomers are now in a better position to interpret observations of supernova remnants thanks to computer simulations of these cataclysmic events by RIKEN astrophysicists1. When certain types of stars die, they go out in a blaze of glory-an incredibly powerful explosion known as a supernova. One of the most common forms of supernova, type Ia, starts with a dense white dwarf star that has

In the recent past, space missions dedicated to the study of astrophysical signals in the high-energy spectrum revealed a series of enigmatic excesses not predicted by the theoretical models. In order to find an explanation for these anomalies, many solutions have been proposed. The most exciting hypothesis invokes the contribution of the elusive dark matter, the mysterious form of matter 4 time

Designed to spot potential natural hazards and help researchers measure how melting land ice will affect sea level rise, the NISAR spacecraft marks a big step as it takes shape. An SUV-size Earth satellite that will be equipped with the largest reflector antenna ever launched by NASA is taking shape in the clean room at the agency's Jet Propulsion Laboratory in Southern California. Called

WASHINGTON — NASA officials say the agency is still planning to make selections as part of its Human Landing System (HLS) program by the end of next month as it takes into account the reduced funding for the program.

WASHINGTON — OneWeb plans to start offering broadband from space in the Arctic region this fall, a capability the company hopes will attract U.S. military and other national government customers.

“Our focus now is Alaska and the Arctic,” OneWeb’s head of government services Dylan Browne told SpaceNews.
