Our interstellar visitor is visible again after reaching its closest approach to the Sun yesterday. The PUNCH mission, a group of small satellites studying the Sun, spotted comet 3I/ATLAS as it came out of the Sun’s glare. The interstellar comet, the third known object formed in another star system to be tracked through our Solar […]

Bowhead Whales Can Live For 200 Years – This May Explain Their Extraordinary Longevity
The bowhead whale is the world’s longest-living mammal, sometimes making it to a staggering 200 years old. How does it do it? A new study sheds some light on the secrets of this curious cetacean’s extreme longevity – and it could have ramifications for how we tackle aging in our own species too. As well […]
Trump Orders First Nuclear Weapons Test In The US Since 1992 – Here’s What You Need To Know
US President Donald Trump has revealed on social media that he has instructed the Pentagon (now known as the Department of War) to resume nuclear weapons testing in the United States for the first time in 33 years. According to Trump, the decision to conduct the highly controversial tests stems from a need to keep […]
Tiny Triceratops-Tackling Tyrannosaur Was Its Own Species, Not A Baby T. Rex
Two paleontologists think they have settled a long-standing debate as to whether certain fossils from the very end of the Cretaceous represent a distinct species of small tyrannosaur, or juvenile T. rex, as many had assumed. Their evidence relies on one of the pair of “Dueling Dinosaurs”, fossils that show a Triceratops fighting for its life […]
What Makes Ammolite Gemstones, A Rare Kind Of Fossilized Ammonite, So Vibrant? It’s All In The Nacre
At IFLScience, we often like to talk about the Mantelpiece Of Dreams, a line-up of rare geological trinkets we’d like to shine down on us as we sit on the sofa (were it not for, you know, ethics). London Natural History Museum’s Professor Paul Barrett said he’d like a triceratops skull (nice), our own Eleanor […]
Something Melted This Tesla’s Windscreen. Could It Have Been A World-First Meteorite Collision?
On October 19, South Australian vet Dr Andrew Melville-Smith’s newly collected car was struck by something, leaving damage unlike anything repairers have seen before. The South Australian Museum has requested access to the car to collect samples, and suspects this may be the first recorded case of a meteorite striking a car while it was […]
Carnivorous “Death-Ball” Sponge Among 30 New Deep-Sea Weirdos Discovered In The Southern Ocean
There’s always a lot going on in the deep ocean, but anyone who had “carnivorous ‘death-ball’ sponge” on their bingo card for 2025 deserves to win the prize. It’s one of 30 new species discovered by researchers exploring the deep dark depths of the Southern Ocean, some of them pretty peculiar – even for the […]
Chimps Can Revise Beliefs When Confronted With Conflicting Evidence. Can You?
Chimpanzees at Uganda’s Ngamba Island Sanctuary can do what was once considered an exclusively human trait: form expectations on the basis of evidence, but revise them on learning new facts. Responding to evidence is an essential skill for the survival of any animal, but given how often humans neglect our supposed superpower, seeing another species […]
Explosive Airbursts, Like Tunguska, Might Be Hiding Among “Halloween Fireballs” Meteor Shower
Meteor showers are the product of comets or asteroids dropping debris on their orbit. Once these debris streams cross the Earth, they burn up in the atmosphere, creating the shooting stars that we know and love. Many famous comets are responsible for famous showers, but the most prolific seems to be Comet Encke. It might […]
One Of The World’s Rarest Penguins Is Actually Three Subspecies In A Trench Coat
Genetic analysis of the hoiho, also known as the yellow-eyed penguin, has revealed that this species is in fact made up of three distinct subspecies – knowledge that could be crucial in preventing these rare and notoriously shy birds from going extinct. Found solely on the New Zealand mainland and Enderby and Campbell Islands, the […]
“I Am The Allergen”: The Super-Rare Condition That Makes Everyone Else Allergic To You
Being allergic to other people is one thing (and it sounds terrible, honestly). But imagine if the opposite were true – and everybody else were allergic to you. It sounds like the monkey’s paw interpretation of an asthmatic’s lament, but it’s an oh-so-real phenomenon. It’s called “People Allergic To Me” – often shortened to PATM […]
42,000-Year-Old Yellow Crayon Suggests Neanderthals Created Art – And It’s Still Sharp Too
The creation of art has historically been thought of as a distinctly Homo sapiens behavior, but the recent discovery of a crayon-like piece of ocher that’s at least 42,000 years old adds to a growing body of evidence suggesting that our Neanderthal cousins also dabbled in a bit of symbolism. Researchers came to this conclusion […]
IFLScience Investigates The Loch Ness Monster: A Round-Up Of Our Spooky Season Nessie Deep Dive
This month, we’ve been diving into one of the world’s most famous mysteries: the Loch Ness Monster. From its 1930s media debut to AI-generated “cryptids” reshaping modern folklore, we’re exploring how technology and storytelling keep legends like Nessie alive. And in our new documentary, we head to Loch Ness ourselves, speaking to experts, monster hunters, […]
Why An Eastern Pacific Tear In Earth’s Crust Could Spare The Pacific Northwest… Eventually
An enormous area of the Earth’s crust has torn and slumped, dropping about 5 kilometers (3 miles). We’ve only just noticed because this is happening beneath the Pacific Ocean, but what sounds alarming could eventually end one of the planet’s most dangerous earthquake fault lines. The San Andreas Fault gets most of the USA’s attention […]
JWST Reveals Never-Before-Seen Details Of The Red Spider Nebula And It’s Spectacular
Stars like our Sun turn into red giants as they run out of hydrogen to fuse at their core. As the star continues to age, it will blow out its outer layers until the only thing that remains is an exposed core, a white dwarf. Before getting to the white dwarf state, Sun-sized stars can […]
“Breaking Records By Extraordinary Margins”: 22 Of Earth’s 34 Vital Signs At Record Levels
Of the planet’s 34 vital signs, 22 are now at record levels, with many still skidding and nosediving in the wrong direction. The rest of this article is behind a paywall.

“The Most Important Unsolved Problem In Pure Math”: Where Is Humanity At With Prime Numbers?
As physics has its atoms, so math has the primes: numbers that are indivisible into any smaller constituent pieces. When we first learn about them, some time in grade school, they’re usually presented as an interesting little aside – strange blips in the number line that might occasionally make long division a bit more difficult, […]
The “Great Halloween Solar Storms”: 22 Years Ago, One Of The Most Powerful CMEs Ever Hit Earth
Halloween 2003 was a real treat for stargazers, yet rather tricky for astronauts, pilots, and satellite operators. Out of seemingly nowhere, three monstrous sunspots appeared in late October, bombarding the Earth with a series of freakish solar storms that triggered a Halloween light show unlike any other. The rest of this article is behind a […]
IFLScience Investigates The Loch Ness Monster: A Documentary On The Science, The Story, And The Power Of Belief
The skipper opened his laptop to a preloaded page. With one hand on the boat’s shift and throttle, he managed to start some footage while simultaneously adjusting the boat’s position against the wind. It was a subtly impressive display of skill, but it didn’t hold our attention for long as the footage started to play. […]
Remarkably Preserved 23-Million-Year-Old “Frosty” Rhino Discovered In Canadian Arctic
An ancient, and adorably named, new rhino species has been discovered in the Canadian Arctic. The exceptionally well-preserved and almost complete fossil represents the northernmost rhino species found to date, and belonged to a beast that roamed this region around 23 million years ago. The new species, unearthed in Haughton Crater on Devon Island, Nunavut, […]
