Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the abundance of gamma rays in the universe.
Scientists developed advanced dating methods to track geological changes on the far side of the moon and found evidence of relatively recent activity.
The International Space Station (ISS) National Laboratory highlighted the rapid growth of space-based R&D in its annual report, released today by the Center for the Advancement of Science in Space® (CASIS®). Over the past fiscal year, the ISS National Lab sponsored more than 100 payloads delivered to the orbiting laboratory—the second-highest annual total to date. Also this year, ISS National Lab-related results were published in 51 peer-reviewed articles—the most ever in a year—underscoring the vital role of the ISS National Lab in advancing scientific discovery and innovation.
The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, Harvard researchers think they have a good explanation for a warmer, wetter ancient Mars.
Building on prior theories describing the Mars of yore as a hot again, cold again place, a team led by researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have determined the chemical mechanisms by which ancient Mars was able to sustain enough warmth in its early days to host water, and possibly life.
