Today’s stories range from Enormous Impact Flash seen illuminating Jupiter’s atmosphere to Did China Just Detect Signals from an alien civilization to a new place for consciousness in our understanding of the universe, and much more.
Seven mysteries of the solar system that scientists have not yet solved. Why is our moon so weird? Was there ever life on Mars? Great cosmic questions lurk in our heavenly backyard. The next time you look up at a bright full moon, think about this: No one knows exactly where the moon came from,” reports VOX.
Massive impact flash seen illuminating Jupiter’s atmosphere Astronomers spotted a huge space rock that collided with Jupiter, causing a burst of light and energy equivalent to 2 million tons of TNT — the brightest event since 1994, New Scientist reports.
This is the most important equation in cosmology:-If you want to understand the universe cosmologically, you just can’t do it without the Friedmann equation. With that, the cosmos is yours, Big Think reports. “While Hubble’s law, v = Hr, was the equation that provided an observational basis for the expanding universe, the Friedmann equations, derived years earlier, formed the basis for modern cosmology. Today, the first Friedmann equation is absolutely indispensable, from the Big Bang to dark energy and everything in between.”
What is time? The Mysterious Essence of the Fourth Dimension The nature of time is a tricky concept to pin down. But whether it’s a fundamental part of our universe or just an illusion has huge implications, asks New Scientist.
Mysterious Objects: Largest Known Population of ‘Immortal’ Brown Dwarfs Revealed –“It is estimated that up to 60 billion brown dwarfs make their home in the Milky Way. Because these elusive celestial bodies don’t fuse hydrogen at their cores, they spend their lives cooling off as they lose that gravitational energy from their formation, changing as they age from the appearance of a low-mass star to resembling Jupiter. Every brown dwarf ever created still exists because they can’t fuse hydrogen together, giving them a quiet, sustainable existence over the vast span of the cosmos.
Did China Just Detect Signals of an Alien Civilization? asks Leonard David for Space.com —“A report, by the state-sponsored Science and Technology Daily, quoted Zhang Tonjie, chief scientist of an alien civilizations search team co-founded by Beijing Normal University, the National Astronomical Observatory from the Chinese Academy of Sciences and the University of California, Berkeley.” China’s Ministry of Science said this week it had picked up signs of alien life on the world’s largest radio telescope — and then seemed to quickly remove a report on the discovery.
New Maps of Asteroid Psyche Reveal an Ancient World of Metal and RockThe varied surface suggests a dynamic history, including metallic eruptions, asteroid-shaking impacts and a lost rocky mantle, MIT reports.
Astronomers discover a nearby multi-planet system-Just 33 light-years from Earth, the system appears to be harboring two Earth-sized rocky planets, MIT reports.
NASA embarks on a risky mission to investigate UAPs, reports Axios. “But by launching the investigation, NASA is wading into an area rife with conspiracy and messages that are difficult to verify, which could put the agency’s stellar public reputation at risk.”
Is life the result of the laws of entropy? – Nearly 80 years ago, Erwin Schrödinger used the physics of the time to try to understand the origin of life. Now Stephon Alexander and Salvador Almagro-Moreno are trying to do the same with modern science, New Scientist reports.
The cosmos can kill us in many ways. But the James Webb Space Telescope can help save us –The James Webb Space Telescope (JWST) will study many dangerous cosmic phenomena, knowledge of which could help save humanity, Big Think reports. If we don’t want to end up like the dinosaurs, we must eventually become a multiplanetary species.”
Controversial claim that the universe is skewed could rock cosmology Our understanding of the universe is based on the cosmological principle: the assumption that on the largest scales it looks more or less the same in all directions. What if that’s wrong? asks New Scientist.
Google engineer claims his AI is sensitive. It’s definitely not – The engineer working on Google’s AI, named LaMDA, suffers from what we might call Michelangelo’s syndrome. Scientists should beware of hubris, Big Think reports.
James Webb Space Telescope Was Hit by a Small Space Rock – But It’s OK –One of the mirrors of NASA’s massive new space observatory, the James Webb Space Telescope, was hit by a small space rock larger than anything tested on the ground, New Scientist reports.
Something Strange Affects Venus’ Atmosphere: Is It Life? asks The Daily Galaxy. –“Researchers from the University of Cambridge have concluded: “If life were responsible for the sulfur (SO2) levels we see on Venus, it would break everything we know about the atmospheric chemistry of Venus.”
Mysterious cold blobs can hide in a distant star–A small star called AU Microscopii appears to contain strange hydrogen particles more than 1,500°C cooler than the rest of the star, and astronomers aren’t quite sure why, New Scientist reports.
A mysterious intergalactic force pushes against the Milky Way, reports Paul Sutter for Space.com. “The name may be a little silly, but it’s real. It’s nothing to worry about either – just a normal consequence of the usual process of structure-building that’s been going on in the universe for years. [checks watch] 13.8 billion years. Meet the dipole repellant.’
A new place for consciousness in our understanding of the universeTo understand mysteries like quantum mechanics and the passage of time, theorists are trying to reformulate physics to include subjective experience as a physical component of the world, New Scientist reports.
Astronomers commemorate the origin of the planets, reports Rebecca Boyle for Quanta. Observations of distant planets have led to an almost complete rewrite of the story of how our solar system came to be.
The GAIA Revolutionreports Sky & Telescope – “Astronomers will use the latest data from the Gaia mission to explore stellar tsunamis, the history of the Milky Way and more.”
Record-breaking Voyager spacecraft begins to shut downThe pioneering probes are still working after nearly 45 years in space, but they will soon lose some of their instruments, Tim Folger reports for Scientific American.
Canadian Telescope Delivers Deepest Ever Radio View of Cosmic Web –Data from the CHIME radio observatory is a milestone in the search for the hidden origins of the universal structure, Scientific American reports.
Fastest growing black hole of the past 9 billion years found Australian-led astronomers say -Scientists see extremely luminous object propelled by a supermassive black hole, reports The Guardian. The supermassive black hole consumes the equivalent of one Earth every second and has the mass of 3 billion suns, they estimate. Scientists discovered an extremely bright quasar, a luminous object powered by a supermassive black hole, using the SkyMapper Southern Sky Survey – a 1.3-meter telescope in Coonabarabran, New South Wales.
Something Strange Affects Venus’ Atmosphere: Is It Life? reports The Daily Galaxy. “Researchers from the University of Cambridge have concluded: “If life were responsible for the sulfur (SO2) levels we see on Venus, it would break everything we know about Venus’ atmospheric chemistry.”
Physicists rewrite the fundamental law that leads to disorder, reports Philip Ball for Quanta. The second law of thermodynamics is one of the most sacred in all of science, but it has always been based on 19th-century arguments about probability. New arguments trace the true source to the streams of quantum information.
