New Horizons is a long, long, long way from home. Fifteen years after launching from Earth at a record speed, and six years since it became the first-ever spacecraft to fly by Pluto, NASA's New Horizons is about to reach a mile marker that only four other robotic probes in history have surpassed.

Scientists have confirmed the discovery of a planetoid four times farther from the Sun than Pluto, nicknamed 'Farfarout.'

As the UAE’s Hope spacecraft arrives at Mars, those involved have a mix of confidence and concern about the chances of successfully entering orbit.

SpaceX has been awarded a $150.4 million contract to launch as many as 28 satellites for the Pentagon’s space agency, the Defense Department announced Dec. 31.

This year, SpaceX launched the first privately owned capsule carrying NASA astronauts to the space station and back. NASA, as well as private companies, also made giant leaps for space travel in 2020.

A Japanese spacecraft is nearing Earth after a yearlong journey home from a distant asteroid with soil samples and data that could provide clues to the origins of the solar system, a space agency official said Friday. The Hayabusa2 spacecraft left the asteroid Ryugu, about 300 million kilometers (180 million miles) from Earth, a year ago and is expected to reach Earth and drop a capsule containing the precious samples in southern Australia on Dec. 6.

Researchers tapped by NASA just conducted a first test of a decades-old concept.

European space officials will this week unveil detailed plans for a series of ambitious missions aimed at returning humans to the moon in the next few years. Projects will include construction of crew quarters for an orbiting lunar space station, making the power and propulsion units for America’s Orion spacecraft, and designing and building a sophisticated communication and refuelling unit, known as Esprit, to serve astronauts on the lunar surface. These missions will be carried out jointly with Nasa and the Japanese and Canadian space agencies.

The Red Planet is undoubtedly an exciting place, but there are others we ought to start thinking about visiting in earnest.

China could be the second country to operate a rover on Mars.

The landing site is in the Outback of South Australia.

Scientists think a planet larger than Earth lurks in the far reaches of the solar system

An analysis of images of the dwarf planet's surface and computer simulations of its interior have led researchers to propose a "hot start" scenario for Pluto's formation as the solar system, including Earth, took shape.

In 1995 a pair of scientists discovered a planet outside our solar system orbiting a solar-type star. Since that finding—which won the scientists a portion of the 2019 Nobel Prize in Physics—researches have discovered more than 4,000 exoplanets, including some Earth-like planets that may have the potential to harbor life.

Bright radio signals from Titan indicate the presence of ancient lake beds in its tropics, a new analysis finds.

There are many Earth-like planets where we could start interstellar colonies. But life on a super-Earth would be very different than life on Earth.

Europe's Solar Orbiter (SolO) probe makes its first close pass of the Sun on Monday, tracking by at a distance of just over 77 million km. SolO was launched in February and is on a mission to understand what drives our star's dynamic behaviour. The close pass, known as a perihelion, puts the probe between the orbits of Venus and Mercury.

New calculations come up with estimate for worlds capable of communicating with others

Peering so deeply would require adding a space component to the Event Horizon Telescope.

The real Lord of the Rings is Saturn, a massive outer planet boasting a set of rings about 27 Earths wide. Being a gas giant like Jupiter, Saturn shares many of its attributes: a strong magnetic field generated by churning metallic hydrogen deep inside, raging storms in its gaseous upper atmosphere, and a diversity of planet-like moons that are worlds unto themselves. Saturn’s rings and larger moons are visible even from small backyard telescopes.
