☆ A 'cosmic glitch' in the universe is forcing astronomers to rethink Einstein's theory of relativity
▼ + stars: | 2024-05-20 | by ( Ellyn Lapointe | ) www.businessinsider.com time to read: +8 min

Einstein's general theory of relativity states that the curvature of space-time causes gravity. But zoom out to enormous scales like clusters of galaxies spanning billions of light years across, and the laws of Einstein's gravity theory appear to change. A 1% adjustment may not sound like a big deal, but it's enough to suggest that Einstein's theory may need a rethink. Now, with this cosmic glitch, there's a new explanation on the table. NASA/CXC/Univ of Missouri/M.Brodwin et al; NASA/STScI; JPL/CalTechThe fact that this cosmic glitch could potentially help astronomers resolve the Hubble tension is a good sign that it may truly exist.

☆ Astronomers say we may live at the center of a cosmic void 2 billion light-years wide that defies the laws of cosmology
▼ + stars: | 2024-05-15 | by ( Jessica Orwig | Ellyn Lapointe | ) www.businessinsider.com time to read: +8 min

But the kicker is that this giant void shouldn't exist in the first place. For example, some people have correctly argued that such a void shouldn't exist in the standard model, which is true. Cosmologists have a value, called the Hubble constant, which they use to help describe how fast the universe's expansion is accelerating. The Hubble constant should be the same value wherever you look, whether it's close by or very far away. NASA/JPL-CaltechAstronomers can't agree on what's causing this discrepancy in the Hubble constant, and the contention has become known as the Hubble tension.

☆ Webb telescope spies millions of stars in stunning spiral galaxies

CNN —The James Webb Space Telescope has captured scintillating portraits of 19 spiral galaxies — and the millions of stars that call them home — in unprecedented detail never seen before by astronomers. Astronomers believe that about 60% of all galaxies are spiral galaxies — and our solar system resides in one of the spiral arms of the Milky Way galaxy. Webb’s observations can help astronomers better understand star formation and the evolution of spiral galaxies like our own. The James Webb Space Telescope captured images of 19 spiral galaxies in near- and mid-infrared light. The images will be used to help astronomers determine the distribution of gas and dust in spiral galaxies, as well as how galaxies both nurture and cease the formation of stars.

"For your typical brown dwarf just traversing the galaxy in solitude, your brown dwarf is very mysterious.

New details of the celestial feature have emerged in the colorful image, which unites the observational powers of Hubble Space Telescope in visible light and the James Webb Space Telescope in infrared light, which is invisible to the human eye. Hubble has long been used to search for faint, distant galaxies across different wavelengths of light. This cosmic effect occurs when closer objects — such as the galactic clusters — act like a magnifying glass for distant objects. The Webb and Hubble composite image includes "Mothra," a star system magnified by the galactic cluster pair as well as another unseen object. NASA/ESA/CSA/STScIThe team nicknamed the star system Mothra due to its extreme magnification and brightness.

Earendel was first discovered by the Hubble Space Telescope last year. Webb is 100 times more powerful than Hubble, though, and it captured previously unseen colors of the distant star. Those colors reveal that being the farthest star we've ever detected does not make Earendel lonely — scientists believe it has a companion star beside it. Stars as massive as Earendel do typically have companions, but Hubble was unable to detect one for Earendel. Thanks to the Webb Telescope's powerful infrared vision, though, scientists believe they can see, for the first time, a "cooler, redder companion star" beside Earendel.

The two have been observed and studied by space and ground-based telescopes since the 1950s, but the highly sensitive Webb telescope allowed for the highest-resolution and most detailed image yet. NASA/ESA/CSA/Joseph DePasquale (STScI)The Webb telescope illuminates information about the origins of our universe, but the appearance of this mysterious object in the background of this image leaves more questions than answers. The cosmic question mark hasn’t been closely observed or studied, so scientists aren’t exactly sure about the object’s origins and makeup. The question mark shape could also be “indicative of a merger where these two galaxies are interacting gravitationally,” Britt said.
