Today’s stories include The Enduring Mystery: How Big is the Universe? to the Planets that the Webb Space Telescope has Observed So Far to Saturn’s Lost Moon, and much more.
JWST’s First Glimpses of Early Galaxies Could Break Cosmology–The James Webb Space Telescope’s first images of the distant universe shocked astronomers. Is it a miracle or a revolution to discover unimaginably distant galaxies? asks Jonathan O’Callaghan for Scientific American.
The Search for Intelligent Life is About to Get More Interesting Jon Gertner reports for The New York Times. “There are an estimated 100 billion galaxies in the universe, home to an unimaginable abundance of planets. And now there are new ways to spot signs of life on them.”
How big is the Universe? We still don’t know, Big Think. It would be easy to believe that all of our technology, such as the James Webb Space telescope, would allow us to know the size of the Universe. But we don’t.
What is beyond the Observable Universe?The Daily Galaxy asks. “Astronomers estimate that the observable universe — a bubble 14 billion light-years in radius, which represents how far we have been able to see since its beginning — contains at least two trillion galaxies and a trillion trillion stars,” writes Dennis Overbye in New York Times Science. “Most of these stars and galaxies are too far and too faint to be seen with any telescope known to humans.”
How Long Does It Take to Reach the Edge of the Universe –See you in a quadrillion years or so. Don’t forget to pack zillions of tons of snacks! Randall Munroe writes for The New York Times.
The human race may have just one last chance to experience human intelligence of this level before machines take control.Martin Rees is an astrophysicist and writes for The Conversation. “The lifetime of an organic civilization may be millennia at most, while its electronic diaspora could continue for billions of years. If we include this in the equation, it seems there may be more civilizations out there than we thought, but that the majority of them would be artificial.”
Do we search for smart Aliens or dumb Aliens?–There are two ways to look for extraterrestrial life. We’ve been focusing on only one, reports Adam Frank for The Atlantic.
These are all the planets observed by the James Webb Space Telescope so far–From bizarre distant gas giants to the intricate bands of Jupiter, this is what the Webb telescope has been up to, reports Matthew Rozsa for Salon.com.
Wow! signal is still an enigma, 45 years after its detection, but at least one possibility so far can’t be ruled outInverse reports that the answer is “Yes.” “There’s another possibility that hasn’t been considered, and it’s called a stochastic repeater.”
This trait of Red Dwarf Star Systems may help us solve the Red Sky Paradox.Science Alert. “There’s something very peculiar about Earth, aside from all the organisms crawling all over it. It’s our star, the Sun, that’s weird: It’s a yellow dwarf. Sun-like stars make up a small percentage of the Milky Way. It’s estimated that fewer than 10 percent of the stars in our galaxy are G-type stars, like the Sun.”
How quantum physicists search for life on exoplanetsTanner Stening reports for Northeastern University
“Lost” moon could explain several Saturn mysteries,New Atlas reports that astronomers agree. “Saturn is home to several solar system mysteries. Using data from Cassini, astronomers now suggest a simple answer to a few questions – a lost moon once orbited the planet before being torn to shreds.”
Is there life on Mars? This Could Be the Place NASA’s Rover Helps Us Find It–Rocks collected by Perseverance are filled with organic molecules, and they formed in a lake that would have been habitable a few billion years ago, reports The New York Times.
Swiss Government Scientist Says It’s Possible to Discover Alien Life. Is Futurism right? Futurism asks. “Dr. Sascha Quanz of Switzerland’s state-run Swiss Federal Institute of Technology said he thinks humans are likely to discover life beyond our planet within the next 25 years.”
Where is quantum uncertainty derived? Ethan Siegel asks Big Think. No matter how precise our measurement equipment is, certain quantum properties have an inherent uncertainty. Is it possible to figure out the reason?
Only 1500 light years from Earth, the closest black hole is located–A black hole with a mass about 10 times that of the sun is thought to be the closest to Earth discovered so far. New Scientist reports that it orbits a star which could host planets. The black hole would then be visible in the sky.
