Solar system

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.

One day our star will run out of fuel and start expanding, engulfing Mercury, Venus and Earth in the process.

Evidence of a ninth planet at the edge of the solar system was announced by Caltech researchers three years ago.

Scientists have previously predicted the existence of a large planet lurking in the farthest reaches of the Solar System. However, no observational evidence for this world has been found to date.

Voyager 2 recorded an increase in cosmic rays from outside the solar system since August.

The spacecraft will hopefully return to Earth in 2023 with space rock samples from the surface of the asteroid.

The cloud was spotted in the skies above Arsia Mons—a massive, 12-mile-high volcano close to the Red Planet’s equator.

Parker has surpassed the previous close approach record set in April 1976 by the German-American spacecraft Helios 2.

One of the waves is estimated to be around six miles high.

Hubble has been operating for more than 28 years.

The Voyager mission has revolutionized our understanding of the outer Solar System.

In the decades since its inception, the agency has overseen numerous missions which have expanded our knowledge of the Earth, the Solar System and the rest of the universe.

The comet was discovered hurtling through the solar system in 2017, but its origins have remained a mystery.

A new study suggests that the Red Planet could have supported subsurface microbes.
