Can the cosmic rays bombarding the lunar surface be used to identify subsurface water ice deposits? This is what a recent study and iposter presented at the 56th Lunar and Planetary Science Conference (LPSC) hopes to address as a team of researchers developed a novel method called the Cosmic Ray Lunar Sounder (CoRaLS) capable of detecting subsurface lunar water ice deposits that are elusive to current radar systems. This study has the potential to help expand the human presence on the Moon since water ice deposits are currently being focused on the permanently shadowed regions (PSRs) of the Moon for the upcoming Artemis missions.

What drives us to send probes throughout the Solar System and rovers and landers to Mars? It's not cheap, and it's not easy. It's because we live inside a big, natural puzzle, and we want to understand it. That's one reason. But the main reason for space exploration is to search for life beyond Earth. That our planet could be the only planet to host life is a disquieting thought.

The search for evidence of life on Mars just got a little more interesting with the discovery of large organic molecules in a rock sample. The Mars Curiosity Rover, which is digging in the Martian rock beds as it goes along, tested pieces of its haul and found interesting organic compounds inside them.

Suppose humanity was faced with an extinction-level event. Not just high odds, but certain-sure. A nearby supernova will explode and irradiate all life, a black hole will engulf the Earth, a Mars-sized interstellar asteroid with our name on it. A cataclysm that will end all life on Earth. We could accept our fate and face our ultimate extinction together. We could gather the archives from libraries across the world and launch them into space in the hopes that another civilization will find them. Or we could build a fleet of arks containing life from Earth. Not people, but bacteria, fungi and other simple organisms. Seed the Universe with our genetic heritage. Of all of these, the last option has the greatest chance of continuing our story. It's an idea known as directed panspermia, and we will soon have the ability to undertake it. But should we?

There's a well-established paradigm in planetary body exploration. It begins with a flyby, then later an orbiter, and then, if possible, a lander. Previous spacecraft have performed single flybys of Europa, and the Europa Clipper orbiter is on its way to Jupiter's moon Europa for a more detailed orbital study of the frozen moon. Hopefully, a lander will follow. A presentation at the recent Lunar and Planetary Science Conference showed how the Europa Clipper can help find the best landing sites on the icy ocean moon for a future Europa lander.

The focus is all on the Moon at the moment as we strive to establish a permanent lunar base. At the south polar region there are permanently shadowed craters protecting pockets of water ice. Korea’s Pathfinder Lunar Orbiter (KPLO) has been capturing images of these craters using its ShadowCam instrument. Now, using that data, planetary scientists are using a machine learning algorithm to identify over a billion impact craters in the region, deep inside the shadowed craters and each is at least 16 metres in diameter.

Got clear skies this weekend? If clouds cooperate, observers in the North Atlantic and surrounding regions may witness a rare spectacle: a partial solar eclipse. This is the second eclipse of 2025, and bookends the first eclipse season of the year. The season started with March 14th total lunar eclipse. Depending where you are observing from, this is a shallow to a deep partial, ‘almost’ total solar eclipse.

It’s been almost 10 years since Breakthrough Starshot began funding research into interstellar missions. Back then, state of the art meant a tiny lightsail just 0.25mm across, skip forward to today and, following their funded research, a new prototype has been revealed measuring 60mm x 60mm and just 200 nanometres thick! We are not quite able to use it to hop to Proxima Centauri but the technology keeps advancing until that day arrives.

What happens when you mix clouds of gas and dust, strong outflows, and energetic shock waves at the core of the Milky Way Galaxy? Space tornadoes. At least, that's how researchers using the Atacama Large Millimeter Array in Chile to study the galaxy's heart described what they found.

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.

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.

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!

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.

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.

The James Webb Space Telescope has given us a view of the earliest moments of galaxy formation in the Universe. It's also revealed a few surprises. One of these is the appearance of small, highly redshifted objects nicknamed "little red dots (LRDs)." We aren't entirely sure what they are, but a new study points to an answer.

Telescope optics can be made of mirrors or lenses, but in both cases, they're bulky and need to follow a strict mathematical curve to focus light. Researchers have shown that it's possible to make a completely flat lens that focuses light. Traditionally, this has been done with Fresnel lenses, but they distort colors. Their new technique carves tiny concentric rings into a substrate that matches the wavelengths of different colors, allowing a full-color, in-focus image.

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.

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.

When Betelgeuse goes off, it's going to be the show of a lifetime. But it’s not going to hurt us.

Supernova explosions are powerful enough to cause mass extinctions if they're close enough. But can we tie supernovae to any of Earth's five mass extinctions? New research shows supernovae could be responsible for the Late Devonian and Late Ordovician mass extinctions.

Gravitational slingshots are now a common part of space missions where the trajectory of a spacecraft is altered using the gravity of another body. These often bring fabulous opportunities for an extra bit of bonus science such as that demonstrated by ESA’s Hera mission on its way to asteroid Dimorphos. It’s following up on the DART 2022 impact but to get there, it’s used the gravity of Mars. It came within 5,000 km of the red planet and on its way, was able to take a look at Mars’ smaller moon Deimos from its far side.
