A new study shows how methane snow accumulates on Pluto's mountain peaks. These snowcaps - first seen by New Horizons in 2015 - look a lot like ones on Earth, but form in a very alien environment.

Blue Origin's New Shepard rocket successfully launched an uncrewed test flight on October 13, with both its capsule and booster later executing a flawless landing.

Are there worlds out there - orbiting distant stars - even better suited for life than Earth? Might they be older, larger, warmer, wetter and with longer-living stars? Now astronomers have identified 24 possible superhabitable worlds.

Astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon - known as a tidal disruption event - is the closest such flare recorded to date at just over 215 million light-years from Earth.

The James Webb Space Telescope - successor to the Hubble - just passed a series of environmental testing trials, designed to simulate the rigors of its anticipated launch in 2021.

Interstellar space isn't just vacuum. It's full of gases, elements, and dust - very thinly spread, to be sure - but the building blocks of stars and planets.

Scientists with the European Space Agency say that the Mars Express orbiter has found evidence of three more salty lakes below Mars' south pole. The discovery comes two years after the first lake was detected in 2018.

Do you want to be a planet-hunter? NASA has launched a new citizen science website called Planet Patrol where volunteers can help search for exoplanets in data from the TESS space telescope.

After 2 weeks of scrubs, SpaceX's Falcon 9 rocket blasted off October 6, 2020, carrying 60 more Starlink satellites to orbit. The rocket successfully landed at sea 9 minutes later. Video of the launch and landing here, plus steps taken to reduce the bright satellites' effect on astronomy.
