Can We Steal Energy from Black Holes? Part 1: Leveling Up Spacetime

Roger Penrose found a way to extract energy from a spinning black hole without breaking any laws of physics. To understand it, we first have to level up our picture of spacetime, from Newton's empty stage to a swirling, draggable fabric. from Universe Today https://ift.tt/Bx7PTjW via IFTTT

Astronomers Use Rare Ultra-Magnetic Star to Crack a Quantum Mystery

An international team observed a magnetar known as 1E 1547.0–5408 using NASA’s Imaging X-ray Polarimetry Explorer (IXPE), leading to what could be the first detection of vacuum birefringence taking place in the magnetar’s ultra-strong magnetic field. These findings could potentially resolve a long-standing mystery quantum mechanics. from Universe Today https://ift.tt/D7iaSXL via IFTTT

NASA Highlights Next-Gen Cargo Landers Paving the Way for a Moon Base

NASA and its commercial partners are making progress on their way to a permanent human presence on the Moon. As part of that, a recent press release and accompanying YouTube video hints they may be looking to provide regular updates to the progress of those efforts - and, at least for this first one, that progress looks pretty good. from Universe Today https://ift.tt/96Bx8cs via IFTTT

Synchronized Stars Power Cosmic Radio Laser

Researchers have helped unravel the mystery of why certain pairs of stars pulse with regular, long-period bursts of radio waves. The particular class of objects they observed come in pairs that always include a compact dead star, called a white dwarf, locked in orbit with an M dwarf, a red star smaller than our Sun. from Universe Today https://ift.tt/NZECWYk via IFTTT

Dry Martian Meteorite Reveals Early Water in Mars's Crust

Billions of years ago, Mars was hypothesized to have been a habitable world with flowing liquid water and the potential for life. But directly studying its ancient past is currently limited to orbiters and rovers, as scientists have yet to obtain direct samples from Mars. However, meteorites have been found on Earth to have potentially originated from Mars during large impacts that flung chunks of the Red Planet into space, eventually being grabbed by Earth’s gravity and crashing into the Earth’s surface. from Universe Today https://ift.tt/P1f7c8r via IFTTT

The CosmoQuest Satellite Will Listen to the Early Universe From the Far Side of the Moon

A tiny UK-developed satellite, roughly the size of a small carry-on suitcase, could help answer one of the biggest questions in cosmology: what happened in the roughly 150 million years of cosmic dark ages, before the universe’s first stars appeared? from Universe Today https://ift.tt/O4KDuQ3 via IFTTT
