NASA’s Webb Identifies Earliest Supernova to Date, Shows Host Galaxy

 Hey, Space Placers!

Webb image shows hundreds of galaxies of all shapes and sizes against the black background of space. Toward the center-right is a large box that zooms in to show a faint red dot with the label GRB 250314A.

NASA’s James Webb Space Telescope identified the source of a super bright flash of light known as a gamma-ray burst: a supernova that exploded when the universe was only 730 million years old. Webb’s high-resolution near-infrared images also detected the supernova’s host galaxy.

FROM NASA:
NASA’s James Webb Space Telescope has observed a supernova that exploded when the universe was only 730 million years old — the earliest detection of its kind to date. Webb’s crisp near-infrared images also allowed astronomers to locate the supernova’s faint host galaxy. The telescope took these quick-turn observations July 1 in support of an international group of telescopes that detected a super bright flash of light known as a gamma-ray burst in mid-March. NASA’s missions are part of a growing, worldwide network watching for fleeting changes in the skies to solve mysteries of how the universe works.

 Hey Space Placers AND AURORA CHASERS! OCTOBER 10, 2024 AURORA OVER CENTRAL VIRGINIA TAKEN WITH SMARTPHONE Greg Redfern The Sun has unleashed a solar event that impacted Earth yesterday  https://www.swpc.noaa.gov/news/cme-passage-continues-today-16-apr-2025  and has intensified even more today. Earth is experiencing a Level G3 Geomagnetic Storm https://www.swpc.noaa.gov/news/cme-passage-continues-today-16-apr-2025     today that will produce the Northern Lights (Aurora) tonight after it gets dark. It is recommended that Aurora chasers check the latest Aurora forecast at the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center Aurora Forecast Webpage  https://www.swpc.noaa.gov/communities/aurora-dashboard-experimental and get outside after dark equipped with their Smartphones and/or cameras. You will need a clear view of the northern horizon that is hopefully free of bright lights. Try looking with your eyes to see if Aur...

 Hey, Space Placers! If a massive asteroid, similar in size to 2024 YR4 or the body that created the Tunguska Event, were to stream through our atmosphere and collide with our planet, it could potentially level an entire city, causing trillions of dollars worth of damage and killing hundreds of thousands or more .

Humanity Is Becoming Part of the Geological Record

Hey Space Placers! According to geologists we are living in the Holocene epoch. But due to humanity's interaction with Earth's biophysical system there is the informal declaration that we are in the "Anthropocene" Era representing the latter half of the 18th Century to present day. Human activity is starting to be seen in the geologic record, from lead, methane and PLASTIC, yes plastic - deposits in the rock layers. Take a moment to read this enlightening article . You'll be glad you did. Sky Guy in VA
