A Distant Galaxy Is Flaring With Strange Regularity, And Scientists Have Figured Out Why

Roughly every 114 days, almost like clockwork, a galaxy 570 million light-years away lights up like a firework. Since at least 2014, our observatories have recorded this strange behaviour; now, astronomers have put the pieces together to figure out why. In the centre of the spiral galaxy, named ESO 253-G003, a supermassive black hole is being orbited by a star that, every 114 days, swings close

Earliest Animal Cave Art on Record Has Been Found in Indonesia, And It’s Adorable

The oldest-known animal drawing in the world is a 45,500-year-old depiction of a hairy, warty pig on a cave wall in Indonesia, a new study finds. The mulberry colored painting, drawn with the red mineral ochre, shows the profile of what is likely a Sulawesi warty pig (Sus celebensis), a wild stubby-legged beast with facial warts that can weigh up to nearly 190 pounds (85 kilograms). These pi

Scientists Just Discovered 3 New Kinds of Carnivorous Sponge in The Deep Ocean

Even though we know the deep sea is weird, 'carnivorous sea sponges' still sound like something from a sci-fi movie. And yet, researchers just announced the discovery of three new such species off the coast of Australia. Go a few hundred metres deep into the ocean, and it starts to look like you're in a whole new world: From a creature that looks like a sea star crossed with an octopus, to shar

Traces of a Mysterious Particle Predicted Decades Ago May Have Been Detected

Evidence of a long-sought hypothetical particle could have been hiding in plain (X-ray) sight all this time. The X-ray emission coming off a collection of neutron stars known as the Magnificent Seven is so excessive that it could be coming from axions, a long-predicted kind of particle, forged in the dense cores of these dead objects, scientists have demonstrated. If their findings are confi

In 1110, The Moon Vanished From The Sky. We May Finally Know Why

Almost a millennium ago, a major upheaval occurred in Earth's atmosphere: a giant cloud of sulphur-rich particles flowed throughout the stratosphere, turning skies dark for months or even years, before ultimately falling down to Earth. We know this event happened because researchers have drilled and analysed ice cores - samples taken from deep within ice sheets or glaciers, which have trapped s

Physicists Observe Fleeting ‘Polaron’ Quasiparticles For The First Time

Polarons are important nanoscale phenomena: a transient configuration between electrons and atoms (known as quasiparticles) that exist for only trillionths of a second. These configurations have unique characteristics that can help us understand some of the mysterious behaviours of the materials they form within – and scientists have just observed them for the first time. Polarons were mea

Dramatic pictures show lightning bolts inside volcanic ash eruption

Storm in an ash cloud: Electrifying shots of Mexican volcanic eruption show lightning bolts striking inside its ash plume Lightning flash spotted in the ash cloud of the Colima Volcano which is 301 miles west of Mexico City Strikes caused by high levels of electric charge building up as ash particles rub together Bolts can heat surrounding air to 3,000°C and melt ash in the cloud into glass

Mungo national park: where alien landscapes reveal ancient culture

A Fatal Skin Disease Afflicting Dolphins Worldwide Has Been Linked to Climate Change

They're among the most popular and captivating animals in the ocean – a creature that delights at every splash or glimpse. And many are dying. A deadly skin condition, first noted in dolphins near New Orleans after Hurricane Katrina in 2005, has now been formally identified by scientists. 'Freshwater skin disease', as researchers define the pathology in a new study, has afflicted coastal c

Wow! Lightning illuminates beautiful thunderstorm over Pacific Ocean

A pilot of a Boeing 767 captured a stunning photograph of a thunderstorm billowing over the Pacific Ocean last month. First Officer Santiago Borja snapped the photo from the cockpit as the plane was passing near Panama at 37,000 feet en route to South America, he told Angela Fr
