Enceladus, the sixth largest of Saturn’s moons, is known for spraying out tiny icy silica particles — so many of them that the particles are a key component of the second outermost ring around Saturn. Scientists have not known how that happens or how long the process takes. A study now shows that tidal heating in Enceladus’ core creates currents that transport the silica, which is likely released by deep-sea hydrothermal vents, over the course of just a few months.

Although it is relatively small, Enceladus — the sixth largest of Saturn’s 83 moons — has been considered by astronomers to be one of the more compelling bodies in our solar system.

Enceladus stands apart from other celestial bodies because of both its appearance and its behavior...

Asteroid Ryugu has a rich complement of organic molecules, according to a NASA and international team’s initial analysis of a sample from the asteroid’s surface delivered to Earth by Japan’s Hayabusa2 spacecraft...

A solar radio burst with a signal pattern, akin to that of a heartbeat, has been pinpointed in the Sun’s atmosphere, according to a new study.

In findings published in the journal Nature Communications, an international team of researchers has reported uncovering the source location of a radio signal coming from within a C-class solar flare more than 5,000 kilometers above the Sun’s surface.

Researchers say the study’s findings could help scientists better understand the physical processes behind the energy release of solar flares – the solar system’s most powerful explosions.

“The discovery is unexpected,” said Sijie Yu, the...
