The Yarrabubba impact crater in Western Australia is the oldest in the world.

Lunar regolith—dust, soil, broken rock and related materials found on the moon's surface—actually consists of between 40-45 percent oxygen.

Aldrin, alongside fellow Apollo 11 crew member Neil Armstrong, touched down on the lunar surface at 8:17 p.m. UTC on July 20, 1969.

The Dragon Crew escape test will explode the Falcon 9 rocket roughly 60,000 feet above Earth.

"I was pretty excited. Coming into the internship, it would be hard to say that I expected to find a planet," Wolf Cukier said.

The volcano is infamous for a catastrophic eruption in 79 A.D. that destroyed the Roman settlements of Pompeii, Herculaneum, Oplontis and Stabiae.

Eleven new recruits completed the two year training program with NASA to become fully-fledged astronauts last week.

"Australia. Our hearts and thoughts are with you," Koch wrote in a Twitter post.

Since September last year, hundreds of fires have burned millions of hectares in Australia, leaving at least 28 people dead.

The "presolar grains" were extracted from a meteorite that crashed in Australia 50 years ago.

According to CNEOS data, there are 14 asteroids predicted to pass Earth this week. The largest of which is wider than the Empire State Building is tall.

The Marree Man is a 2.2 mile geoglyph, whose origins remain a mystery two decades after its discovery.

Based on its brightness, the asteroid is estimated to measure between 919 and 2,034 feet in diameter.

NASA says there are millions of tiny pieces of space debris in orbit above Earth.

As Boeing's Starliner marks its historic maiden voyage to space, we look at what the launch means for the commercial space travel industry.

The latest from NASA's X-plane series could make Concorde-style supersonic commercial flights a reality again without the deafening sonic boom noise.

The results could have significant implications for space weather prediction, particle physics experiments on Earth and our understanding of the sun's atmosphere.

Adidas is putting its footwear technology to the test on a NASA space mission as part of a new long-term partnership with the International Space Station in 2020.

Every giant leap begins with one small step, and we've identified a step that is critical for lunar exploration and settlement.

NASA released a "treasure map" of water ice buried close enough to the surface of mars for potential astronauts to "dig up" with a shovel.

Climate scientists found that 14 of 17 climate models produced between 1970 and 2007 were broadly correct in their predictions, when differences in emissions were accounted for.

"We are discovering that our standard models of the sun are missing some very fundamental physics," Parker Solar Probe scientist Justin Kasper told Newsweek.

The dummies are fitted with more than 5,600 sensors each, which will measure exposure to space radiation.

The picture shows the Daisenryo Kofun, which is believed to have taken 2,000 men an estimated 20 years to build.

The next transit of Mercury will not be until 2032.

The photo was snapped by Jessica Meir, who took part in the first all-female spacewalk last month.

Traces of extraterrestrial sugars on meteorites add more weight to the hypothesis that a meteor blitz on ancient Earth may have kick-started life by providing the necessary building blocks.

Two of Neptune's inner moons are locked together in a type of orbit that has not been seen before. This allows them to cross paths without coming into contact, researchers say.

Since September, roughly 2.7 million acres have burned in the southeastern state of New South Wales.
