Mission engineers were confident NASA's OSIRIS-APEX (Origins, Spectral Interpretation, Resource Identification—Apophis Explorer) spacecraft could weather its closest ever pass of the sun on Jan. 2, 2024. Their models had ...
In 1974 Stephen Hawking famously claimed that black holes should emit particles as well as absorb them. This so-called "Hawking radiation" has not yet been observed, but now a research group from Europe has found that Hawking ...
Sometimes, science requires traveling into hazardous environments; sometimes it requires a vast influx of state capital and an army of researchers and technicians. But sometimes, science has to call in the Marines. We reported ...
There are millions of asteroids floating around the solar system. With so many of them, it should be no surprise that some are weirdly configured. A recent example of one of these weird configurations was discovered when ...
A new, higher-resolution infrared camera outfitted with a variety of lightweight filters could probe sunlight reflected off Earth's upper atmosphere and surface, improve forest fire warnings, and reveal the molecular composition ...
NASA's Psyche spacecraft passed its six-month checkup with a clean bill of health, and there's no holding back now. Navigators are firing its futuristic-looking electric thrusters, which emit a blue glow, nearly nonstop as ...
Mercury is a toxic heavy metal that can exist stably as a gas, with high volatility and global distribution in the atmosphere. Volcanoes represent a primary natural source of Hg in the atmosphere, with significant effects ...
A team of astronomers at Nanjing University has found evidence that Mars likely has more potentially hazardous asteroids in its path than Earth. In their study, posted on the arXiv preprint server, the group investigated ...
It's tiny, but it's there. By now, we're all used to seeing amazing photos of Jupiter courtesy of NASA's Juno mission on a routine basis. Many of these are processed by volunteer "citizen scientists," and they show the swirling ...
One of the wildest wonders of nature is the ability of some animals to reproduce by splitting in half. There is still so much we don't know about this process. So the discovery of a 155-million-year-old starfish fossil frozen ...
