The JunoCam imager aboard NASA's Juno spacecraft captured this image of Jupiter's southern equatorial region on Sept. 1, 2017. The image is oriented so Jupiter's poles (not visible) run left-to-right of frame.

Artist's illustration of what the exoplanet TOI 700 d might look like.

MIT researchers have devised a framework for deciding which type of mission would be most successful in deflecting an incoming asteroid, taking into account an asteroid’s mass and momentum, its proximity to a gravitational keyhole, and the amount of warning time that scientists have of an impending collision.

Artist’s impression of one of the two stars in the FU Orionis binary system, surrounded by an accreting disk of material. What has caused this star — and others like it — to dramatically brighten?

Citizen Scientists Discover Rare Cosmic Pairing

The globular cluster Omega Centauri contains as many as ten million stars. A new study has found five millisecond pulsars at its core.

The image shows a thermokarst lake in Alaska. Thermokarst lakes form in the Arctic when permafrost thaws.

Three-dimensional view of the Martian surface temperature around an idealized boulder at latitude 30°S. On the side opposite to the Sun, temperatures are around -128° Celsius, and as the sun rises, this area heats up rapidly, so frost melts on salt-containing ground before it sublimates into the atmosphere.
