"It's humbling to realize how small Earth is next to this visitor from another solar system," said Pieter van Dokkum from Yale University.

Hibernation technology may enable mission designers to reduce spacecraft mass by around a third.

Currently, we know of about roughly 25,000 near-Earth objects larger than 460 feet in diameter.

Researchers say that the object is moving around ten times faster than most stars in the galaxy.

This celestial event only takes place around 13 times a century.

"We are able to make measurements today that were just not possible during the years of the Apollo program," a NASA scientist said.

Mercury transits take place only around 13 times a century.

The space rock will come within around 2.7 million miles of our planet.

The space rock could measure up to 3,248 feet in diameter.

Geochemistry study suggests the interiors of some exoplanets are very similar to that of Earth.

The comet is only the second confirmed interstellar object to have passed through the solar system.

The Exploration Extravehicular Mobility Unit builds on the designs of spacesuits currently used by astronauts when they conduct spacewalks outside the International Space Station.

"I can't believe we are the only living entity in the universe," Didier Queloz said

Studying the the pressure at the edge of the solar system can help us to better understand the influence of the sun on interstellar space.

Black holes are dead stars that, after exploding as supernovae, have so much mass that nothing can hold them together, causing them to collapse into a singularity.

The Mars 2020 mission is scheduled to launch in July 2020, and it is expected to reach the red planet in February 2021.

Five years ago scientists proposed the hypothetical existence of a large world tens of millions of miles from the Sun, which has come to be known as "Planet Nine."

The building was constructed as a facility to quarantine astronauts and the material they brought back from the moon during the Apollo program.

Researchers from The Europlanet Society presented a study on Venus' climate history at the EPSC-DPS Joint Meeting 2019 on Sunday.

Loki Patera is located on Jupiter's moon Io, one of the most volcanically active places in the solar system.

The photo was taken by the ExoMars Trace Gas Orbiter—a spacecraft developed by the European Space Agency and the Russian space agency Roscosmos.

For the study, scientists recreated the extreme pressure and temperature of the moon's interior in the laboratory.

The planet, HR 5183 b, is three times the size of Jupiter and slingshots around its star along an egg-shaped orbit.

The larger of the two asteroids will come within around 630,000 miles of our planet, according to NASA.

"In the search for life beyond our solar system, the most promising planets might not be Earth twins," says geochemist Stephanie Olson.

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.
