Scientists at NASA's Jet Propulsion Laboratory have recreated spider-like araneiform terrain, a geologic formation found on Mars, in a lab on Earth.

The most comprehensive map of clouds on Mars includes a variety of cloud patterns, including some that are unlike anything seen on Earth.

NASA's Curiosity rover has captured a spectacular sight from the surface of Mars: The first-ever photo of Earth alongside the Red Planet's moon Phobos.

Earth will grab itself another moon this month, but only briefly. The "mini-moon" in the form of asteroid 2024 PT5 will stick around for just two months.

Temperature fluctuations above Antarctica in winter show the earliest warming of the stratosphere on record.

A chance encounter with another asteroid could steer Apophis destructively close to Earth during a future passage.

Using a phenomenon known as gravitational lensing, it might be possible to use the sun as a gigantic telescope to peer deep into space.

Cosmic dust may have helped to kick-start life on Earth, new research suggests. The findings challenge a widely held assumption that this was not a plausible explanation.
