The setting sun created an array of colorful clouds above the European Southern Observatory's Paranal Observatory in the Atacama Desert in Chile, which is home to the Very Large Telescope.

New NASA imagery shows that the St. Patrick bay ice caps have vanished from Arctic Canada, two years sooner than scientists predicted

A team of physicists has devised a simple way to measure the duration of a bizarre phenomenon called quantum tunneling.

Scientists may one day detect alien planets outside the Milky Way using the ripples in space and time known as gravitational waves, a new study finds.

Scientists traced a fast radio burst (FRB) to a known star inside the Milky Way for the first time.

While greenhouse gas emissions plummeted as the world locked down, such dips will do "nothing" to slow climate change unless society moves away from fossil fuels, researchers have found.

Green, pulsing ultraviolet images of Mars' "nightglow" are illuminating circulation patterns in the Martian atmosphere.

Lurking just below the atmosphere of Venus is a wall of acid clouds that whip around the planet at speeds close to that of a commercial air jet on Earth.

Marsquakes recorded by NASA's InSight mission offer the first direct evidence of key boundaries in the Martian interior, which could help planetary scientists understand how rocky planets are formed.

Methane and nitrogen glaciers on Pluto expand and "grow" in response to temperature changes on the dwarf planet, new research suggests.

Our new study, published in Nature Communications, has uncovered some answers.
