Astronomers see 'warm' glow of Uranus's rings

Two telescopes have measured the faint heat from the main, or epsilon ring, of Uranus, enabling astronomers for the first time to determine its temperature: a cool 77 Kelvin.

1.2 billion years ago, a 1-km asteroid smashed into Scotland

New research by a team of UK scientists has located the site of the massive impact that took place in Scotland 1.2 billion years ago. Roughly one billion years ago, Earth experienced a higher rate of meteorite impact than it does today.

Mass anomaly detected under the moon's largest crater

A mysterious large mass of material has been discovered beneath the largest crater in our solar system - the Moon's South Pole - Aitken basin and may contain metal from the asteroid that crashed into the Moon and formed the crater.

Curiosity confirms clay deposits on slopes of Mount Sharp on Mars

Clay often forms in the presence of water – a key ingredient for the evolution of life as it is known on Earth – and Curiosity’s latest findings add more evidence that a significant amount of water once pooled and flowed in Gale Crater on Mars.

An Astounding Amount of Water Discovered on Mars

Scientists detected a massive reservoir of frozen water sandwiched by layers of sand beneath the northern polar ice cap on Mars. This reservoir contains so much ice that, if melted and brought to the surface, it would submerge the entire planet.

Extraterrestrial Organic Matter Found in 3.3-Billion-Year-Old Rock

Geologists in France and Italy have spotted what appear to be organic molecules from outer space in 3.3-billion-year-old rocks in South Africa, according to a new study.

Most of the Solar System Should be a Protected Wilderness

Taking cue from humanity’s most pressing existential threats – overpopulation and climate change – international team of researches recommend that limits be established now before exponential growth strips our System of its resources.

Mars Odyssey Reveals Phobos Using THEMIS

NASA’s aging 2001 Mars Odyssey orbiter recently snapped some unique views of the twin moons Phobos and Deimos.

Surprise 4,000-mile ‘ice corridor’ found on Saturn’s moon Titan

Researchers have spotted surprisingly diverse landscapes on Titan, from broad planes to sandy dunes and even rivers and lakes. And recently a ribbon of exposed bedrock ice that wraps nearly halfway around the moon was spotted there too.

NASA’s InSight lander detects first likely “marsquake”

The signal appears to have been generated inside the planet and not by any surface-level phenomenon. Three other seismic events were detected on 14 March, 10 and 11 April, but they were much smaller and their origins more ambiguous.

Planet Mercury Has Solid Inner Core Same Size as Earth's

Mercury is now the second rocky planet—after Earth—for which we have evidence of a solid inner core. It’s not an exact value, but the mere presence of a solid inner core helps to understand how the planet generates its magnetic field.

We Now Have Independent Confirmation of Methane on Mars

There was a big stir when reports emerged that the Curiosity rover had detected methane on Mars. But now an independent source has also detected methane on Mars.

NASA’s Juno spacecraft sends back new photos of Jupiter

Juno took the photo 8,000 miles from the cloud tops during its 18th close flyby of Jupiter on February 12. Overall, 32 flybys are planned, so Juno is just beginning the second half of its flybys.

Signs that Ancient Rivers Flowed Across the Surface of Mars

There’s a massive, growing wall of evidence showing that Mars may have had the necessary conditions for life in the past. ESA’s High-Resolution Camera on the Mars Express Orbiter, there are clear signs of a system of river valleys.

Meet Neptune's new moon, Hippocamp

Neptune has a new moon, and it’s also the gas giant’s smallest to date — only a little over 20 miles across. It was discovered using the Hubble Space Telescope combined with a new method to track dim objects as they orbit.
