On-Orbit Checkouts in Progress for Mission to Boost NASA’s Swift – NASA Science

Supernova explosions occur when massive stars reach the end of their lives. The outward force of their fusion can no longer support their mass against their gravity, and they collapse and explode. These cataclysmic explosions can light up the sky for months. But some supernovae illuminate the sky for much longer than a few months….

Three years before the skyscraper-size asteroid Apophis makes its very close (but safe) flyby of Earth, scientists have already begun charting exactly when and where billions of people can watch it sweep across the sky. Speaking at an “Apophis T-3 Years” workshop held earlier this month at the University of Padua in Italy, retired cartographer…

Mink numbers in Kent could be cut by 90% within two years under a new project aimed at protecting wildlife. The Waterlife Recovery Trust (WRT) has received a £20,000 grant from the BASC Wildlife Fund to expand trapping and monitoring across Kent, which once had one of Britain’s highest densities of invasive American mink. Conservationists…

In 1993, a team led by the planetary scientist Carl Sagan tentatively concluded that there is life on Earth. Not much of a deduction, you might think — except that the researchers confined their evidence to observations made by the Galileo spacecraft, which had flown past our planet three years earlier on a looping journey…

Buying a new gadget or service today feels like a gamble. Artificial intelligence, machine learning, and deep learning systems are compressing the gap between new and outdated technology. Whether you’re a student, a tech enthusiast, or a small business owner evaluating new tools, the goal is to avoid tech debt by choosing technology that can…
