As these microscopic ice particles settle downward due to gravity, other gases condense around these seeds to coat them. As such, haze particles on Pluto may be largely made of a variety of ices, instead of more complex organic compounds as on Titan. The sizes, amounts and atmospheric distributions of these ice grains in the computer models closely match those of the haze particles detected on Pluto, the scientists noted. … [Read more...] about Pluto’s haze made up of ice crystals with cyanide hearts

The recent boom in SPAC mergers has been so formidable that some companies are going public despite having any shot at near-term profitability. And while much of the attention may wind up focused on the consumer-facing companies, Crane told The Verge in an interview that his team was “wildly successful” in convincing the investors like PIMCO and BlackRock of EVgo’s advantage: making technology that other automakers — big and small — rely on. … [Read more...] about Charging company EVgo is going public via SPAC merger

Lucasfilm One year later, in 4 ABY, the Rebel Alliance attacks the second Death Star. Luke faces Darth Vader and the Emperor tries to turn him to the dark side, but Vader's love for Luke just might bring him back to the light side of the Force. Meanwhile Leia discovers she's Luke's twin sister and the daughter of Darth Vader as she leads the Rebel Alliance to the Empire's downfall. … [Read more...] about How to watch every Star Wars movie and TV show online in chronological order

That's why today's optical clocks measure time by averaging the oscillations of thousands of atoms. But even that method can't get rid of the standard quantum limit. A decade ago, Vuletić and his team, along with researchers from the University of Belgrade in Serbia, had an idea for how to overcome this limitation: Entangle the particles. Quantum entanglement — or "spooky action at a distance," as Albert Einstein famously called it — is the idea that the fates of tiny particles are linked to each other even if they're separated by long distances. So, by entangling the atoms that keep time, the scientists might be able to keep each pair or group of entangled atoms in the same state and thus oscillating at similar frequencies, thereby allowing the clock to overcome the standard quantum limit and measure time more precisely. … [Read more...] about ‘Spooky action at a distance’ could create a nearly perfect clock

Neutron stars can hold themselves up from the crushing weight of their own gravity by a quantum mechanical process called degeneracy pressure. But that pressure has a limit, and with fewer regular neutrons, that limit shrinks. If a star had a 1:1 ratio of ordinary neutrons to mirror neutrons, the maximum mass of neutron stars in the universe would be about 30% less massive than what we would normally expect. More massive than this, and neutron stars would collapse into black holes. … [Read more...] about Neutrons’ ‘evil twins’ may be crushing stars into black holes
