According to theory, all active black holes should produce winds or jets. Astronomers have long searched for wind around the Milky Way’s central supermassive black hole. New images reveal a vacant, cone-shaped region pointing to the black hole. According to new research, only a supermassive black hole could've created this region. from Universe Today https://ift.tt/qU6pf4d via IFTTT

Using data from NASA’s James Webb Space Telescope, astronomers led by researchers at the University of California, Riverside have produced the most detailed map of the cosmic web ever made, tracing the network of galaxies all the way back to when the universe was one billion years old. from Universe Today https://ift.tt/MvAtl7L via IFTTT

Stephen Hawking predicted that stars can capture primordial black holes (PBH). The PBH find their way to the stellar core, creating a Hawking star. There are two possible outcomes, both deadly for the star. Either it explodes rapidly, or it's slowly consumed by the parasitic PBH. from Universe Today https://ift.tt/GgYFAcM via IFTTT

Astronomers have developed a technique that allows them to detect cloud cycles on distant exoplanets. Using data from the James Webb Sapce Telescope (JWST), the astronomers found that mornings and evenings on the gas giant WASP-94A b have extremely different weather patterns: mornings are riddled with sand clouds, while the skies are clear in the early evenings. By isolating the clouds, researchers can more accurately measure a planet’s atmosphere and provide a clearer picture of the planet’s composition. WASP-94A b, for example, has much less oxygen and carbon than astronomers perviously calculated, making its atmosphere much more like Jupiter than they had originally thought. from Universe Today https://ift.tt/y7A40gE via IFTTT

New research shows how unmagnetized worlds like Mars can still deflect some of the Sun's solar wind. Unlike magnetospheres that form around planet's like Earth, this effect takes place in Mars' ionosphere. It's called the Zwan-Wolf effect, and it's not clear how deep into the atmosphere it operates. from Universe Today https://ift.tt/8HYycpf via IFTTT

Scientists using the Euclid space telescope found a red-dwarf brightness “gap” in the population of a globular cluster—an ancient, crowded collection of stars. A similar gap was detected by the Gaia observatory in nearby stellar populations, but it has never before been seen in a globular cluster. from Universe Today https://ift.tt/ula62gM via IFTTT
