Quantum dynamics in chemical reactions parallel black hole information scrambling
Write a comment
Scientists often equate the process of information scrambling in black holes with the ultimate limit of quantum mechanical behavior, where every bit of quantum data is thoroughly mixed. New findings from Rice University, in collaboration with the University of Illinois Urbana-Champaign, challenge this notion by demonstrating that molecular reactions in chemistry can scramble quantum information When and How to Spot the 'Devil Comet'

Comet 12P/Pons-Brooks is one of the brightest known periodic comets. It earned the nickname of "devil comet" in 2023 when an outburst caused the comet to have an asymmetrical appearance, like having horns. It comes around every 71 years and is currently getting brighter as it flies toward the Sun.
In the Northern Hemisphere, the comet is best viewed with binoculars or a small telescope - r We have the watch: NASA Crew-9 visits Space Delta 4

"The first time I launched, my rocket didn't go where it was supposed to go, it had an in-flight anomaly, came apart and we landed in the middle of the Kazakhstan step," said U.S. Space Force Col.

L3Harris Technologies and Aerojet Rocketdyne have concluded a comprehensive series of development and certification tests for the RS-25 engine, confirming its readiness for upcoming Artemis missions, starting with Artemis V. These tests were carried out at NASA's Stennis Space Center, involving a total of 45 development tests and 24 certification tests.

A NASA astronaut, a Russian cosmonaut and Belarus's first ever space traveller on Saturday returned to Earth safely after a fortnight aboard the International Space Station, Russia's Roscosmos agency reported.
"Today, at 10:17am Moscow time (0717 GMT), the descent vehicle of Sozuz MS-24 manned spacecraft landed near the Kazakh city of Jezkazgan," Roscosmos reported.

SpaceX launched a payload of 23 Starlink satellites Friday atop a Falcon 9 booster from Florida's Cape Canaveral Space Force Station Complex.
The spacecraft launched at 5:12 a.m. EDT with the first stage booster rocket separating shortly after liftoff and landing on the drone ship A Shortfall of Gravitas in the Atlantic Ocean shortly afterward.

Just a single, unguarded glance at a solar eclipse can result in a lifetime of vision loss, eye health experts warn.
On Monday, tens of millions of spectators across Mexico, the United States and Canada will witness the Moon completely obscure the Sun's light, a rare celestial spectacle that won't be visible for most of North America again until 2044.

Some who hope to witness Monday's total solar eclipse may see the sun obscured by clouds instead of by the moon.
There's still some time for forecasts to change, but meteorologists predict that eclipse day storms could blanket parts of the path, which stretches from Mexico and Texas through Maine and parts of Canada.
If clouds don't get in the way, viewers in the path wearing eclipse glasses will see the moon begin to slowly cover the sun until it is completely blocked, a period of darkness called "totality" during which temperatures drop and the sun's corona will be visible.
What's the forecast along the eclipse's path?
Clouds are expected in much of the eclipse's path Monday thanks to storms that are moving across the central U.S.
Huge star explosion to appear in sky in once-in-a-lifetime event
Write a comment
Sometime between now and September, a massive explosion 3,000 light years from Earth will flare up in the night sky, giving amateur astronomers a once-in-a-lifetime chance to witness this space oddity.
The binary star system in the constellation Corona Borealis—"northern crown"—is normally too dim to see with the naked eye.
But every 80 years or so, exchanges between its two stars, which are locked in a deadly embrace, spark a runaway nuclear explosion.
The light from the blast travels through the cosmos and makes it appear as if a new star—as bright as the North Star, according to NASA—has suddenly just popped up in our night sky for a few days.

A Russian space capsule with two women and one man safely landed in a steppe in Kazakhstan on Saturday after their missions aboard the International Space Station.
The Soyuz MS-24 carrying Russia's Oleg Novitsky, NASA's Loral O'Hara and Marina Vasilevskaya of Belarus touched down southeast of the remote town of Dzhezkazgan at 12:17 p.m.
