Credit: ZME Science/Midjorney. In 2024, scientists studying ancient sediments in the eastern United States reported signs of a comet exploding in Earth’s skies 12,800 years ago. That event, they suggested, might have plunged the planet into a thousand-year cold spell known as the Younger Dryas. Now, a new study has taken the search deep beneath the ocean, and the results …

On the 1st of July 2025, the Asteroid Terrestrial-Impact Last Alert System (ATLAS) in Chile spotted a new comet entering our solar system. This comet was named 3I/ATLAS, as it’s only the third interstellar object humans observed passing through our solar system. The previous two interstellar bodies discovered were 1I/’Oumuamua (spotted in 2017), and 2I/BORISOV (detected in 2019). It seems …

It takes deep, below-the-navel brazen audacity to take on Google in online search. Just ask Microsoft, DuckDuckGo, Brave and the slew of other search engines that have tried to scrape away at Google’s near 90% global market share. It takes a kick in the head to think Google would sell Chrome, its wildly popular web browser. It seems that AI …

From ground observatories, based on its brightness, the original best estimate for the size of its nucleus was anywhere from 10-20 kilometres in diameter. New data from Hubble has significantly reduced that, putting an upper limit on the comet’s size of 5.6 kilometres wide. That’s still substantially larger than both 2I/Borisov and 1I/’Oumuamua, which were estimated at being roughly 500 …

Astronomers at the Pan-STARRS Observatory in Hawaii made history in 2017 when they detected ‘Oumuamua, the first interstellar object (ISO) ever observed. Two years later, the interstellar comet 2I/Borisov became the second ISO ever observed. And on July 1st, 2025, the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Rio Hurtado detected a third interstellar object in our Solar System, the …

Comet 3I/ATLAS has been observed by the Hubble Space Telescope, which delivered new insights into this third interstellar visitor. The orbital observatory has refined the estimates about the size of the cometary nucleus and confirmed that the comet is the fastest ever to come from beyond the Solar System. The comet was discovered on July 1 by the NASA-funded Asteroid …

A comet visiting our solar system from another star is only the third known interstellar object to pass our way. The approach of 3I/Atlas has sparked interest and curiosity in the astro community, but one prominent Harvard physicist has raised the possibility that it is more than a typical comet. This image provided by NASA/European Space Agency shows an image …

Tiny metallic beads hiding in deep Arctic mud have reignited a long-running argument about why Earth shivered 12,800 years ago. The new evidence comes from four sediment cores lifted out of Baffin Bay, between Greenland and Canada, that capture a razor-thin layer rich in comet-like debris. The abrupt climate lurch, known as the Younger Dryas, drove Northern Hemisphere temperatures down …

Scientists have found new evidence that a massive comet trail may have caused climate upheaval on Earth more than 12,000 years ago. Tiny particles detected in ocean sediment cores suggest that dust from a large, disintegrating comet entered Earth’s atmosphere around the beginning of the Younger Dryas event, a period of abrupt cooling that caused temperatures in the Northern Hemisphere …

Thanks to the Hubble Space Telescope, we now have the sharpest image yet of the interstellar visitor 3I/ATLAS, showing that it is clearly a comet, with a coma filled with dust particles and the first hints of a tail. Of course, 3I/ATLAS is no ordinary comet. Discovered on July 1, 2025 by the Asteroid Terrestrial-impact Last Alert System (ATLAS), 3I/ATLAS …
