Euclid studies Milky Way center, supports future Roman observations

WASHINGTON — The U.S. Space Force has placed into operational service a new mobile satellite-jamming system capable of temporarily disrupting an adversary’s communications. The electronic warfare system, known as Meadowlands and built by L3Harris Technologies, uses radio-frequency signals to interfere with an adversary satellite’s ability to transmit information. Unlike anti-satellite weapons designed to physically destroy…

Despite continual habitability headlines, the debate over whether Mars ever had or currently has life still rages. At every new planetary conference, someone presents data that often for a few weeks at least appears to change the calculus of Martian astrobiology. But for well over two decades now, one of the biggest mysteries remains —…

For the first time in over half a century, NASA has a rocket standing on a launch pad to send people back to the moon. After many years and billions of dollars in development and rigorous testing and uncrewed flight tests, the Space Launch System (SLS) and Orion spacecraft are finally almost ready to take 4…

A new study from the SETI Institute suggests that the search for extraterrestrial intelligence may be facing an unexpected challenge. The same stellar activity that shapes conditions around distant planets could also make alien radio signals much harder to detect. Many SETI efforts look for extremely narrow radio signals because they are unlikely to be…
