When the first known comet from interstellar space was spotted traversing the Solar System in late August of last year, astronomers snapped to attention. 2I/Borisov was an extraordinarily rare opportunity to study the formation of comets around other stars. In those initial measurements, 2I/Borisov seemed a heck of a lot like comets from the outer Solar System. But a new analysis has revealed t

For those of you who aren't familiar with the Prince Rupert's drop, this weird, scientific enigma is a seemingly simple glass object created by dripping molten glass into very cold water. That process creates all kinds of crazy physical properties, which we'll go into later, but the end result is a teardrop-shaped piece of glass that's practically unbreakable at its bulbous 'drop' end, but will

Data from a network of newly installed weather stations atop Mount Everest shows that the mountain experiences some of the most intense sunlight on the planet. As alpine mountaineers are all too aware, the sun can be brutally fierce atop snow-capped peaks. Preliminary data from the weather stations on Mount Everest suggests this effect is amplified to an astounding degree at the top of the w

They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange "sediment organism" that could do things nobody had ever seen before in bacteria. This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with time scientists found it could make other things too, like bacterial n

One of the defining characteristics of the mysterious deep-space signals we call fast radio bursts is that they are unpredictable. They belch out across the cosmos without rhyme or reason, with no discernible pattern, making them incredibly hard to study. Now, for the first time, astronomers have found a fast radio burst (FRB) that repeats on a regular cycle. Every 16.35 days, the signal nam

NASA's Christina Koch returned to Earth safely on Thursday after shattering the spaceflight record for female astronauts with a stay of almost 11 months aboard the International Space Station. Koch touched down at 09:12 GMT on the Kazakh steppe after 328 days in space, along with Luca Parmitano of the European Space Agency and Alexander Skvortsov of the Russian space agency. Koch was shown s
