WASHINGTON — The once highly-classified ability to detect and pinpoint the locations of radio frequency (RF) emissions from space is rapidly transitioning to the commercial sector — giving companies new powerful capabilities for all sorts of surveillance and intelligence gathering. Interest in RF monitoring from space has soared in recent years as geopolitical conflicts disrupt

For an experiment designed to reverse time, the apparatus was surprisingly simple: little more than a tank of water. With a puff of air to disturb the surface, Emmanuel Fort created a set of ripples moving outwards in concentric circles. Then, as the waves spread, he gave the tank a practised jolt – at which

WASHINGTON — The Space Development Agency (SDA) wants to give commercial space companies a chance to prove their mettle for future military satellite contracts. The agency on May 31 released a solicitation for its “Hybrid Acquisition for Proliferated LEO” (HALO) program, which aims to establish a pool of pre-approved vendors eligible to compete for upcoming

If traversable wormholes exist, we could potentially detect their plasma blasts Rostislav Zatonskiy / Alamy Wormholes that are surrounded by matter, like the ring that gathers around a black hole, could create strange rotating clouds of hot plasma. Anything that falls in one end could shoot out the other at 200 million kilometres per hour,
