Solar System

Jupiter now boasts the largest number of moons orbiting it after scientists discovered another 12 moons, bringing the behemoth's total up to 92.

Even as the James Webb Space Telescope is allowing astronomers to see inside vast, distant galaxies, it's also studying some tiny, nearby objects, albeit inadvertently.

Comet C/2022 E3 (ZTF) is tantalizing to spot through a telescope, but what would it look like up close?

Get your telescopes ready: Uranus will disappear behind the moon on Saturday (Jan. 28) and the event will be visible to a select few in Asia or the far north of the world.

From the nearby moon to distant Triton, planetary scientists have a plethora of ideas for how to explore our solar system.

Jupiter's moon Io is the most volcanic body in the solar system, with outbursts occurring yearly. A particularly large volcanic eruption was spotted in the fall of 2022.

The five planets of the solar system visible with the naked eye can all be seen this January, making the start of 2023 a special time for astronomers.

NASA's Juno spacecraft is recovering its memory after a download disruption following its December flyby of Jupiter.

Humans have sent four spacecraft out of the solar system, with another swiftly approaching the edge of our solar system — and they have a lot to teach us about our place in space.

Take a grand tour of the solar system tonight (Dec. 28) as each of the planets in the solar system will be visible at the same time.

From identifying safe landing sites on Europa to understanding craters on the moon, machine learning is helping planetary scientists push the boundaries of space exploration.

One year after its launch, the flagship space telescope is already making discoveries that are transforming our knowledge of the universe, both near and far.

New research shows that even smaller impacts can warm and soften enough ice on Jupiter's moon Europa to send material sinking into the underlying ocean.

A rocky meteoroid that exploded over Canada last year was more extraordinary than it first seemed: it originated from the outer solar system, where scientists thought only icy bodies exist.

When NASA scientists were planning the Mars Perseverance mission, they decided to try something new: Instead of just sending a rover, they'd also send up a small helicopter.

It was the first planetary flyby ever.

Astronomers used 200,000 Hubble Space Telescope images to discover an eerie glow surrounding the solar system even after all other light sources have been eliminated.

Measurements taken at Earth's neighbors, Mars and Venus, show the battle between high-energy cosmic rays from beyond the solar system and the influence of the sun in the inner solar system.

Astronomers observed a major eruption from a volcanic comet flying through the solar system, likely spewing more than 1 million tons of debris into space.

It's been a cloudy season for Saturn's largest moon, Titan.
