You’ve probably heard before that Earth has witnessed five mass extinctions. It’s a number plucked straight from the fossil record, but that’s not the whole picture, not even close. Evidence from ancient rocks reveals the oldest die-off in our planet’s history most likely occurred among single-celled organisms more than 2 billion years ago. A recent

The second de-orbiting manoeuvre of Chandrayaan -2 spacecraft was successfully carried out early Wednesday, the Indian Space Research Organisation said, inching towards achieving a historic soft-landing on the lunar surface. The nine-second de-orbiting or retro-orbiting manoeuvre was executed at 3:42am using the onboard propulsion system, the space agency said. “With this manoeuvre, the required orbit

In 2019, NASA is once again preparing for human missions to the Moon. We’re keeping the promise by developing new systems and spacecraft, making innovations in flight and technology, living and doing science on the International Space Station, and delivering images and discoveries from our home planet, our solar system and beyond. This video is

A team of researchers has just demonstrated quantum enhancement in an actual X-ray machine, achieving the desirable goal of eliminating background noise for precision detection. The relationships between photon pairs on quantum scales can be exploited to create sharper, higher-resolution images than classical optics. This emerging field is called quantum imaging, and it has some

WASHINGTON — Less than a month after announcing a new effort to provide low-cost launch services for small satellites, SpaceX says it will increase the number of flight opportunities and reduce the prices it offers. The revamped smallsat rideshare program, the company announced late Aug. 28, will provide launch opportunities at least once per month

Here’s a simple how-to on how to construct a traversable cosmic wormhole that could send your spaceship to the furthest reaches of space: take two charged black holes, place them back to back, and thread two cosmic strings through both. Stretch both strings to infinity and presto! You’ve got yourself a traversable wormhole. Confused yet?
