Venus has been hiding a secret for fifty years. Just below its main cloud deck sits a mysterious layer of haze that spacecraft first detected in the 1970s and nobody could explain where it came from. Now a research team in Japan has finally cracked it, and the answer comes from the last place most people would think to look!

Every star you've ever looked at is hiding a magnetic secret and it may have been hiding it since birth. A new theoretical study has connected, for the first time, the magnetic fields detected deep inside dying red giants with the magnetism found at the surfaces of their long dead remnants. These fields may be ancient fossils, born early in a star's life and surviving billions of years of violent transformation completely intact.

The Sun is the most studied star in the universe, yet some of its most violent behaviour remains stubbornly out of reach. Solar flares, explosive eruptions that can disrupt satellites, knock out power grids and bathe astronauts in radiation release enormous bursts of X-rays that carry vital clues about what drives them. Now, a team of Japanese engineers has built the sharpest X-ray telescope ever to fly on a solar mission, and the technology it has pioneered could soon fit inside a satellite the size of a shoebox.

Thirty four years ago, a group of Cornell scientists looked at a remote Chilean mountaintop and imagined what might be built there one day. That day has arrived. The Fred Young Submillimeter Telescope has just opened its eyes on the universe from one of the most extreme observatory sites ever chosen, and the science it promises to deliver from the first moments after the Big Bang to the hidden nurseries of newborn stars.

In 1937, Ettore Majorana asked a question nobody else was even thinking about: does a particle have to have a distinct antiparticle? For neutrinos — which carry no charge — the answer might be no. They might be their own antiparticles. Deep underground right now, experiments are watching atoms decay, waiting for the signal that would prove it. So far: nothing. But the case is not closed.

Rovers equipped with Radioisotope Power Systems (RPSs), aka. nuclear reactors, could effectively explore the craters in the Moon's southern polar region.

They are the most abundant particles in the universe, yet we barely know they exist. Neutrinos stream through everything, through walls, through planets and even through you…. in their billions every second, leaving no trace. We've known for decades that they have mass, but pinning down exactly how much has defeated physicists for years. Now, the most sensitive experiment ever built has pushed our knowledge to a new frontier, and what it found raises a profound question about why these ghostly particles are so extraordinarily light.

The lunar south pole is where humanity plans to build its first permanent outpost but we still don't fully understand what lies beneath the surface. A new study has used radar to peer below the ground in one of the Moon's most complex and battered regions and what it's finding raises important questions about the geological minefield that future astronauts will be navigating. Ancient impacts, frozen melt sheets, and billions of years of overlapping debris may complicate our plans more than we thought.

When a massive star explodes on the far side of the universe, the light from that explosion normally fades long before it reaches us. But occasionally, the universe conspires to help. A newly discovered supernova has been caught using the gravity of an entire galaxy as a natural magnifying glass, boosting its light by at least a hundred times and revealing a stellar death that would otherwise have been completely invisible. It is the most magnified supernova ever found, and it opens a remarkable new window onto the distant universe.

Around 900,000 years ago, an impactor slammed into modern-day Kazakhstan and excavated a crater about 14 km in diameter. It was the most recent hypervelocity impactor powerful enough to trigger a nuclear winter, but not an exinction. New research suggests the crater is almost twice as large, showing that the energy released by the impact was much greater than thought.

Neutrinos have mass — yet they never flip between left- and right-handed states the way every other massive particle does. The most logical fix is Paul Dirac's: invisible right-handed neutrinos that interact with nothing whatsoever. The math works. It even produces a beautiful explanation for why neutrino masses are so absurdly tiny. But it requires believing in particles that are permanently, in-principle undetectable.

An ultra-hot Jupiter exoplanet orbiting a nearby star gave scientists using the Gemini South telescope a look at how both a star and its hot planet can have similar chemical compositions. The team, led by Arizona State University graduate student Jorge Antonio Sanchez, took spectra of the planet, called WASP-189b, using the Immersion Grating Infrared Spectrograph instrument. The observations measured the abundance of magnesium compared to silicon in the hot planet's atmosphere and allowed the team to compare it to the makeup of its parent star.

Saturn is one of the most recognisable and studied planets in the Solar System, it was the first thing I ever saw through a telescope and yet it is still finding ways to surprise us. New research analysing data from NASA's Cassini spacecraft has revealed a significant and unexpected quirk in Saturn's protective magnetic bubble, one that confirms the giant planets of our Solar System play by completely different rules to Earth.

For the first time in history, scientists have used a spacecraft on the far side of the Moon to search for signals from extraterrestrial intelligence. China's Chang'E-4 lander sat in the most radio quiet location humanity has ever placed an instrument, shielded from Earth's constant electronic chatter by the entire bulk of the Moon itself. They found nothing but that is almost beside the point!

Deep in the heart of a distant galaxy, two monsters are locked in a death spiral and for the first time, they have been caught them in the act. A new study has confirmed the first close pair of supermassive black holes ever detected, orbiting each other every 121 days and closing in fast. If the models are right, they could collide within a century.

A new study challenges old assumptions by revealing that water on the Moon likely came from multiple sources over billions of years, rather than from a single major deposit long ago.

The weak nuclear force is the eccentric cousin of the four forces — the one that only shakes hands with left-handed particles. That bizarre preference turns out to be absolutely critical for stars, nuclear fusion, and the existence of most matter. And neutrinos love it. There's just one problem: neutrinos appear to only exist in one handedness, which makes no sense at all.

Every piece of electronics ever sent to Venus has been destroyed within hours of landing, cooked alive by surface temperatures hot enough to melt lead. Now a team of engineers at the University of Southern California has built a memory chip that laughs in the face of that heat, surviving temperatures hotter than molten lava and it started with a happy accident!

What if the same collisions we think of as forces of destruction were actually the spark that created life on Earth? New research published in the Journal of Marine Science and Engineering is making a compelling case that meteor impacts didn't just reshape our planet's surface, instead that they may have built the very cradles where life first emerged.

A crater the size of two football pitches has appeared on the Moon and for the first time, scientists have been able to watch exactly what happened. Captured by NASA's Lunar Reconnaissance Orbiter before and after the impact, this remarkable discovery is giving planetary scientists an unprecedented close up of one of the Solar System's most fundamental processes. Here's what they found.
