Today’s stories include Astronomers discover traces of ‘super-supernovas’ that destroyed earliest stars to Where is the center of the Universe? You can read more.
Is there a center of the Universe? There, there, everywhere –The Big Bang is commonly misunderstood, warping our understanding about the Universe’s size and shape, reports Big Think. “The Universe may be infinite, but even if it is not, the observable part of it is just an incomprehensibly tiny part of the whole. Any spot in the Universe is considered the center. Indeed, you may be the center of the Universe.”
Hubble Detects Protective Shutter Defending a Pair Dwarf Galaxies,NASA reports. For billions of years, the Milky Way’s largest satellite galaxies – the Large and Small Magellanic Clouds – have followed a perilous journey. “A lot of people were struggling to explain how these streams of material could be there,” said Dhanesh Krishnarao, assistant professor at Colorado College. “If this gas was removed from these galaxies, how are they still forming stars?”
Astronomers discover traces of ‘super-supernovas’ that destroyed earliest stars,Robert Lea reports for Space.com. The team examined chemical traces of Population III stars using a 13.1-billion-year-old quasar.
This Astrophysicist holds Star Data in Her Hand: “What if you could hold part of the galaxy in your hands? Or, you could look into an orb to see the birthplaces of stars. By combining astrophysics and art, that’s exactly what Dr. Nia Imara does reports NPR Science Friday. She’s a visual artist and assistant professor of astronomy at UC Santa Cruz, based in Santa Cruz, California.”
Contact with ET – How would humanity respond? reports Leonard David for Space.com –“That knowledge would likely have far-reaching effects on our view of ourselves and our place in the universe. Researchers are looking into the potential psychological impacts of such an announcement, which some people might have a hard time accepting.”
Physics Scientists Revisit a Quantum Rule That Conflicts With Our Universe, reports Charlie Wood Quanta.com. “The past and the future are tightly linked in conventional quantum mechanics. Perhaps it is too tight. The theory may be reworked to allow quantum possibilities for expanding space. For over 90 years, physicists searched for a solution, a deeper description of reality that includes both quantum mechanics as well as gravity. But the quest has run up against thorny paradoxes.”
The Milky Way is ‘rippling’ like a pond, and scientists may finally know why,Brandon Specktor reports for Live Science. “Picture someone dropping a stone the size of 400 million suns into that water. The calm is broken. Wave after wave of energy ripples across the galaxy’s surface, jostling and bouncing its stars in a chaotic dance that takes eons to calm. Astronomers suspect that something like this may have really happened — not just once, but several times over the past several billion years.”
China’s Mars rover finds hints of catastrophic floods–Radar images reveal clues to the history of a largely unexplored region, reports Nature. “China’s Zhurong rover has peered deep under the surface of Mars, finding evidence of two major floods that probably shaped the region the robot has been exploring since it landed in May 2021.”
Ground Telescopes Capture Jaw Dropping Views of DART Asteroid Inflation--Telescopes all over the world focused their attention on the historic collision. They revealed a surprising large and bright impact cloud, reports George Dvorsky, Gizmodo. “NASA’s DART mission to ram a kinetic impactor into a harmless asteroid went perfectly yesterday, resulting in the desired destruction of the spacecraft. And as views from Earth showed, the effects of the impact weren’t subtle.”
