Alternative explanation for landslides in Mars
Long landslides on Mars may have been caused by vibrations of unstable light rocks at the bottom of the slide. The findings, which offer an alternative view to previous suggestions that the landslides were […]

Satellite data, algorithms can help predict volcanic eruptions
Satellite radar and algorithms can be used to determine when a volcano is on the verge of an eruption. Interferometric synthetic aperture radar images can show ground movement at volcanoes and an […]

New image offers closer view of interstellar object
Astronomers used the W.M. Keck Observatory’s Low-Resolution Imaging Spectrometer to take a new image of 2I/Borisov, the second interstellar object ever observed passing through our solar system. The image shows the coma […]

Clues point to possible fifth fundamental force
Physicists say they’ve gathered more evidence that there could be a fifth physical force in addition to gravity, electromagnetism and a pair of nuclear interactions. The researchers say they’ve glimpsed a force carried […]
