The snow contained substantial quantities of dust-enriched with iron-60—which isn't naturally produced on our planet.

The main aim of the spacewalk is to install a special piece of equipment which will enable the space station to accommodate new spacecraft designed by private companies.

Warmer conditions on Ancient Mars increase the possibility that life developed there, according to researchers.

Researchers detected gravitational waves—ripples in space-time—emanating from a cataclysmic event around 900 million light years away.

The endeavor to put the first woman—and the next man— on the moon will likely cost between $20 and $30 billion over five years.

The latest findings could help to explain some puzzling measurements collected by the Juno spacecraft, which is currently orbiting the planet.

"Uncontrolled biological contamination of the Moon's surface is not scientifically ideal," said Lisa Pratt, director for NASA's Office of Planetary Protection.

Of course, more detailed work is needed to verify that the true complexity of the observations can also be modelled successfully.

Japanese researchers propose new plan to hunt down our galaxy's "isolated black holes."

"The LightSail 2 mission is a game-changer for spaceflight and advancing space exploration," said Bill Nye, whose Planetary Society funded the project.

The exoplanet, dubbed WASP-121b, is located around 900 light-years from Earth.

As we celebrate the 50th anniversary of the moon landing this month, we must revitalize America's commitment to space.

Einstein's general theory of relativity beautifully describes the nature of gravity and its effect on large objects in the universe. However, there are alternative explanations.

Nova Spivack wants to preserve all of mankind's knowledge, back it up and store it across the solar system for future civilizations.

The Teegarden star—a red dwarf with a mass less than a tenth that of the sun—is located just 12.5 light-years away in the constellation Aries.

Before its mission ended in September 2017, NASA's Cassini probe conducted a series of dives between Saturn's cloud tops and its rings.

Gamma-ray bursts are some of the most extreme events in the universe, producing vast jets of powerful radiation that can be detected billions of light-years from their source.

The ocean is thought to be be billions of years old and may contain as much as three times the volume of all the liquid water on Earth.

Build-ups of toxic gases in the atmospheres of many exoplanets in the "habitable zone" could limit the "safe zone" in which life outside our solar system could actually exist.

The findings expand our knowledge of black holes and the galaxies within which they are often found.

This is the first time a magnetic field has been observed in the filaments connecting clusters.

There are three different physical processes responsible for accelerating particles to vast speeds.
