A Supermassive Black Hole Gets Blamed for Quenching Star Formation

Some of the most massive galaxies in the Universe appear to be missing a lot of stars. That seems unusual, since birthing stars is one of a galaxy's main tasks as it grows. According to Xin "Cindy" Xiang of the University of Michigan, something is suppressing or quenching the births of stars in these and she thinks that black holes might be the culprit. from Universe Today https://ift.tt/NaVIjcP via IFTTT

Habitable Worlds Targets in New Star Activity Catalog

Searching for habitable worlds beyond our solar system consists of more than just having it orbit within its star’s habitable zone, which is the region where temperatures could be just right for liquid water to exist on the surface. On Earth, where water comprises approximately 75 percent of the planet’s surface, life is absurdly abundant. But what about the exoplanet’s star, specifically its activity and rotation? How could this influence how exoplanets are identified for current and future missions? from Universe Today https://ift.tt/LzTryAl via IFTTT

Nautilus Array to Track Missing Exoplanet Atmospheres

Exoplanet atmospheres have become prima targets for astrobiologists in the search for life beyond Earth. This is because exoplanet surfaces can’t be directly imaged yet, so astronomers must get creative with how to search for signs of life, also called biosignatures. Presently, powerful ground- and space-based telescopes like the Atacama Large Millimeter Array (ALMA) and NASA’s James Webb Space Telescope (JWST) are improving in their ability to observe and analyze exoplanet atmospheres. But did these atmospheres form and evolve, and what could this mean for the search for life beyond Earth? from Universe Today https://ift.tt/n0CBvkV via IFTTT

It's Finally Begun! The Vera Rubin Observatory Creating What Will Be the Greatest Movie Ever Made

The Vera Rubin Observatory's long-awaited Legacy Survey of Space and Time has begun. This decade-long movie of the cosmos will capture anything that changes brightness, position, or both in the southern night sky. It will study grand subjects like dark energy and dark matter, and important things closer to home like near-Earth objects. from Universe Today https://ift.tt/S58QXka via IFTTT

The "Shadow Blaster" Galaxy's Role in High-energy Cosmic Neutrinos

On September 22, 2021, the IceCube Neutrino Detector in Antarctica caught a blast of neutrinos as it passed through the solar system. These neutrinos were remarkably high-energy and came from a galaxy 11 billion light-years away. That's a period of the Universe's history known as "Cosmic Noon". It's when star formation in galaxies was at its most active and that provided an interesting clue to their origin. The source of the neutrinos was nicknamed "Shadow Blaster" because the event that created the neutrinos was hidden by a dense cloud of dust, which made it invisible to optical observations. from Universe Today https://ift.tt/JyNlRdW via IFTTT
