Scientists will study the effects of radiation on yeast in preparation for long-duration crewed missions to deep space.

Ancient grains of dust that are older than the solar system itself have been found in samples from asteroid Ryugu brought to Earth by the Japanese Hayabusa2 spacecraft nearly two years ago.

A powerful and spectacular cosmic dance that began a billion years ago will lead to a collision and merger between two galaxies and the supermassive black holes at their hearts.

Scientists studied the trajectory and debris field of asteroid 2008 TC3 to determine which specific parts of the space rock made it down to the Earth's surface.

A Chinese X-ray telescope has detected the strongest-ever magnetic field recorded by making observations of a rapidly-spinning neutron star, or magnetar.

The sun has spat out two clouds of plasma in the past two days, which might trigger beautiful aurora displays observable as far south as New York later this week.

NASA's Space Launch System rocket captured inside the Vehicle Assembly Building at NASA's Kennedy Space Center ahead of its roll out to the launch pad.

Scientists think that when dark photons collect around black holes, they can get trapped and boosted to high energies, where they might transform into other particles (or even just normal photons).

Earth is the only planet we know possesses continents, a scientific mystery, but new research indicates the continents may have been created by meteorite impacts in Earth's distant history.

Studying unusual processes of how ice accumulates below ice shelves here on Earth could hold lessons for the exploration and habitability of Jupiter's moon Europa.

The Lunar IceCube and Lunar Polar Hydrogen Mapper (LunaH-Map) missions will search the moon for water using two different techniques.

Astronomers hope to use pulsars scattered around the galaxy as a giant gravitational wave detector. But why do we need them, and how do they work?

At 'supercriticality,' the difference between the liquid and gas phases of a material seems to disappear. New research finds that this weird tipping point may be simpler than scientists thought.

Dark energy could be caused by pressure from giant voids of nothingness that may be flinging the universe apart.

Earth has experienced five mass extinction events over its 4.5 billion-year history. A sixth mass extinction is underway as a result of human-driven climate change.

Hubble Space Telescope delivers a stunning new image of stellar gas and dust in the Orion Nebula

Scientists using new computational methods have come up with a new insight into the potential workings of the complex atmosphere of Venus.

Within 24 hours of accessing the first stage of Australia’s newest supercomputing system, researchers have processed a series of radio telescope observations, including a highly detailed image of a supernova remnant.

Scientists found a huge field of hydrothermal vents on the East Pacific Rise.

A mountaintop observatory experienced a 'close encounter' in the shape of a cloud that some people associate with UFOs. The real-life explanation is far less alien.
