Compared to the other terrestrial planets, Mercury has always been a bit of a mysterious one. It’s internal structure is very different from its planetary siblings with its core accounting for 70% of its overall mass and an unusually thin mantle composed of silicates. One theory suggests a head-on collision between a larger proto-Mercury and a smaller object while another suggests Mercury sideswiped an Earth-mass object. It may be something completely different and a new paper suggests that a grazing collision between two similarly sized bodies led to the formation of the planet we see today.

Retrofuturistic styling, synthetics with no regard for human life, and people being munched like popcorn — that's the Alien we know and love alright.

Shrouded in thick clouds, our erstwhile sister planet Venus is rife with mysteries. Among the Solar System's rocky planets, Venus is the one begging for more exploration. While potential habitability always catches people's attention, scientists crave more fundamental knowledge about Venus: its geology.

Paris, France is seen lit up in this photo taken aboard the International Space Staton.

The Moon is a common sight in our night time (and sometimes daytime) skies but it hasn’t always been there. The widely accepted theory of lunar formation involves a Mars-sized planet crashing into the Earth, creating a cloud of debris that eventually that eventually coalesced to form the Moon. Estimates of this cataclysmic event that gave us the Moon range from between 4.52 to 4.35 billion years ago however a new presentation at the Lunar and Planetary Science Conference have pushed that timeline back even further!

While the presence of these molecules is not proof of ancient life on Mars, scientists say it shows we could detect chemical signatures of past life, if it ever existed.

U.S. Space Force Col. Nick Hague is back on Earth after living on the International Space Station for the last five-plus months.

During the partial solar eclipse on March 29, 2025, a weird "double sunrise" will grace the skies between Canada's St Lawrence River and the Bay of Fundy, via the easternmost point of the U.S.

Aurora chasers are on high alert for geomagnetic storm conditions overnight with northern lights possible at mid-latitudes.

As ESA’s Hera planetary defence mission flew past planet Mars it autonomously locked onto dozens of impact craters and other prominent surface features to track them over time, in a full-scale test of the self-driving technology that the spacecraft will employ to navigate around its target asteroids.

Breathtaking photos of this month's total lunar eclipse capture a blood red moon and star-studded Milky Way over NOIRLab's Cerro Tololo Inter-American Observatory in Chile.

A strange blue spiral lit up the sky over Europe on Monday night (March 24), with residents of the UK and other countries speculating on its true nature on social media.

Experts are already looking into the risks of piracy in space and solutions to this potentially devastating economic and legal problem.

When it comes to safe places for life, supermassive black holes are probably the last place you'd consider safe for nearby planets, let alone life-bearing ones. There are good reasons for this: those monsters at the hearts of galaxies suck down everything that comes into contact with them. When they do that, they blast out killer radiation. Neither activity is necessarily good for life. Or is it? As it turns out, radiation from these active galactic nuclei (AGN) can nurture life under the right circumstances.

Scientists have detected a fascinating spiral galaxy located about one billion light-years away. At the heart of this cosmic goliath, powerful radio jets are blasting out of its centre, stretching six million light years into space. A team of researchers have suggested that a smaller dwarf galaxy plunged into its centre, passing close to its supermassive black hole triggering immense flares, intense radiation and driving the colossal radio jets. Surprisingly however, despite the tremendous amounts of energy, the galaxy has kept its spiral structure.

China’s Chang’e-6 mission has been exploring the largest crater on the Moon. It’s known as Aitken Basin and is found at the South Pole of the Moon where craters are permanently shadowed. The crater is a whopping 2,500 km across and measures 10km deep and Chang’e-6 data has revealed that a giant asteroid smashed into the Moon about 4.25 billion years ago.

A cosmic coincidence has led to one of the most amazing images ever captured by NASA’s James Webb Space Telescope.

Here's where to be to catch rare views of the cusps of the sun appearing in the east at sunrise during the partial solar eclipse on March 29, 2025.

NASA websites no longer state that the Artemis 3 mission will aim to land the first person of color and the first woman on the moon, but the agency says this does not reflect a change in crew.

We've learned that Interstellar Objects (ISOs) are not strangers to our Solar System. Many have visited, and many more will in the future. The Vera Rubin Observatory is expected to find hundreds each year. Scientists are keen to learn more about them, and a swarm of spacecraft on standby might be the way to do it.
