JWST peers through a cosmic lens in 'deepest gaze' to date | Space photo of the day for May 27, 2025

 Hey, Space Placers!

A massive galaxy cluster, Abell S1063, forms a gravitation lens, revealing the warped light from more distant galaxies dating back to the early universe in this James Webb Space Telescope image. (Image credit: ESA/Webb, NASA & CSA, H. Atek, M. Zamani (ESA/Webb))


From Space.com:

The James Webb Space Telescope captured this stunning image of a galaxy cluster so massive that it serves a gravitational lens, warping the light and revealing more distant galaxies from the early universe.

What is it?

Abell S1063 is a cluster of galaxies that displays a strong gravitational lens effect, in which the light from distant galaxies behind the cluster is bent around it due to Abell S1063's mass, which creates a curvature in spacetime and forms the warped arcs that appear to surround it in the image.

JWST's Near-Infrared Camera (NIRCam) was able to use this effect, previously observed by the Hubble Space Telescope, to reveal a multitude of faint galaxies and previously unseen features.

NORTHERN LIGHTS MAY BE VISIBLE TONIGHT

Image
 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...

Why “city-killer” asteroid YR4’s impact probability keeps increasing

 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
