Solar system

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

The 'abiotic' methane may hold clues about its presence elsewhere in the solar system, researchers say.

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

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

The space rock will come within around 4.6 million miles of our planet, traveling at speeds of 10,400 miles per hour.

Meisner, a NASA Hubble Fellow, is scouring through exabytes of data collected daily to search for undiscovered planets and celestial bodies in our solar system.

The meteor was about a foot wide and was traveling at an estimated 55,000 miles per hour.

On this day, half a century ago, astronauts Neil Armstrong, Buzz Aldrin and Michael Collins took off aboard a Saturn V rocket from Launch Pad 39A at the Kennedy Space Center, Cape Canaveral, Florida, headed for the moon.

Full moons are an astronomical phenomenon which occur around once a month, when the Earth is positioned between the sun and the moon.

Settlements on the moon where astronauts will live permanently or semi-permanently are closer to becoming a reality than ever before.

Total solar eclipses occur when the Moon passes directly between the Sun and the Earth, casting a shadow over certain parts of the planet.

The conference about a "major new science mission" will be held at 4 p.m. EDT.

Titan, Saturn's largest moon, is covered in lakes filled with liquid hydrocarbons, such as methane and ethane.

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

The full moon on Sunday will also coincide with Jupiter appearing particularly bright and large in the night sky.

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.

It was once thought that only young and active stars produced these explosive events, but according to a new study, our 4.6-billion-year-old sun also has the capacity.

NASA's James Webb Telescope will open up an entirely new avenue for searching for extraterrestrial life.

At its closest, the planet's orbit will take it within around 398 million miles of Earth on June 12.

Scientists have long been unable to explain the mystery of why the Sun's outer atmosphere is hotter than its surface.

The space agency investigates new ways to grow plants in space to offer astronauts an alternative to processed food during long missions.

"The formation of the moon and the origin of Earth's water are two of the fundamental open questions in cosmo-chemistry," said the lead author of a new study.

Scientists have long been puzzled by the asymmetrical nature of the moon's two hemispheres.

The findings could have implications for our understanding of how subsurface oceans form on other worlds.

The space agency is hoping to put the first woman on the lunar surface by 2024.

"If we don't think about this now, we will go ahead as we always have, and in a few hundred years we will face an extreme crisis, much worse than we have on Earth now," Martin Elvis said.

A Harvard professor says a meteor that burned up in the atmosphere was traveling too fast to have come from our solar system.

"I knew we were looking at something very rare," said one of the authors of a new study.

The planet was discovered more than a decade ago in the outer reaches of the solar system.

Scientists think that metallic asteroids began their lives as blobs of molten iron, floating in space.
