Question: approx how much more galaxies, dies a jwst deep feild show, compared to the most detailed hubble?maj. tom wrote:New Release.
JWST Advanced Deep Extragalactic Survey (JADES)
You really have to click on this link to zoom in and see some details in the image. But it shows more galaxies in a Deep Field survey than ever thought. Every single point of light (without the diffraction crosses) is a separate galaxy! There are so many redshifted that were captured which shows just how far away they were.

There is a limit to how far back any device can capture because eventually it hits the microwave length red shifted wall of the Cosmic Microwave Background CMB which looks like this in every direction:
Which you can actually see and hear as white static on old timey radios and tv.

Asteroid 2023 BU: Space rock to pass closer than some satellites

2023 BU will pass in orbit within 10,000 km from the center point of Earth on 27 January 2023 00:28 UTC at 9.3km/s. It's estimated to be 4-8 meters diameter (so relax).
This one was only picked up last weekend by amateur astronomer Gennadiy Borisov.

This image displays a wider view of the field of stars and galaxies surrounding the spiral galaxy LEDA 2046648. JWST’s NIRCam instrument has picked out a profusion of smaller, more distant galaxies and bright stars around this galaxy, demonstrating the telescope’s impressive resolution in infrared wavelengths. Calibration images such as this one were critical to verify the telescope’s capabilities as it was prepared for science operations, and this one doesn’t disappoint.

In fact, you might be able to see another pass of a Starlink constellation this evening at 6:47 PM, looking from the northwest to the southeast as it moves across the Caribbean yet again
