In national security space, “dim objects” typically refer to satellites or debris that emit little energy and are hard to see with traditional sensors. Detecting and characterizing them is already ...

We love imagining giant space habitats and futuristic megastructures—but someone has to dig up the raw materials first. Asteroid mining won’t be glamorous: it’ll be isolation, harsh conditions, heavy ...

She warned of "extreme price volatility in financial markets due to catastrophising or euphoria, and a collapse in confidence." ...

Astronomers peering through images from the Vera C. Rubin Obervatory have discovered an unusual asteroid spinning so fast that it's broken the record for how space rocks of its size are supposed to ...

At 710 meters (just under half a mile) wide, this space rock sets a record for how fast it spins on its axis: about one rotation in less than two minutes. That makes it the fastest-spinning asteroid ...

Add Yahoo as a preferred source to see more of our stories on Google. Meteorite chemistry shows which primitive asteroids may hold usable metals or water, and why most space mining remains difficult. ...

Space mining often sounds like a fast route to endless metals. In practice, the first question is simple: what are small asteroids actually made of, in measurable detail? Researchers at the Institute ...
