A research team led by Prof. Tan Peng from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has revealed the temperature regulation mechanism

The formation of Mercury remains an unsolved mystery. The planet closest to the sun has a disproportionately large metallic core—accounting for about 70% of its mass—and a relatively small rocky

NASA introduced its newest astronauts Monday, 10 scientists, engineers and test pilots chosen from more than 8,000 applicants to help explore the moon and possibly Mars.

Advanced space travel relies on a fundamental understanding of the restricted three-body problem (RTBP), in which one of the three bodies—typically a spacecraft—is so small that its gravity doesn’t affect

With help from amateur astronomers, scientists tracked how an asteroid traveled from space, broke up in Earth’s atmosphere and sent fiery fragments shooting to the ground, gathering new information about

The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic events in the universe, producing a variety of signals that can

The universe is a slow-changing place. While it’s mostly true that the heavens and the deep-sky objects in it will look largely the same across an average human lifetime, there

A new class of supermassive black holes embedded in a thick gas shell could explain small red dots in images from the James Webb Space Telescope.

When the ESA launched the Gaia spacecraft in 2013, it didn’t generate the same fanfare as the launch of other missions like the JWST, or first light from telescopes like

A new NASA mission will capture images of Earth’s invisible “halo,” the faint light given off by our planet’s outermost atmospheric layer, the exosphere, as it morphs and changes in
