Title: Webb's 255-hour-long observation reveals invisible dark matter in a map containing nearly 800,000 galaxies
Post by: Redaktion on February 01, 2026, 06:48:35
Using its Near-Infrared Camera (NIRCam), NASA's James Webb Space Telescope peered into a region for a total of about 255 hours. This exceptionally long observation allowed astronomers to trace dark matter by studying how its gravity distorts and influences the light from distant galaxies.

@Chibuike Okpara

Very interesting article, but can you please stop refering to James Webb telescope as "NASA's James Webb Space Telescope"?

It was built by a consortium of space agencies and research centers all around the world, including European Space Agency, Japan, Canada and many others.

Give the correct credit, or don't give at all.

I'm sure you regularly credit America for CERN, given their significant and continual financial and talent contributions to the project, right?

It's mind boggling innit? You get the best telescope in the world (or out of the world) to peer continuously for 255 hours and it comes up with some 800000 galaxies. That's 800000 multiplied by billions of stars in each galaxy!

Why are all the white specs of light red at the bottom, also what is the blue light as we are not supposed to be able to see dark matter, also if dark matter exists where is it.

dark matter exists doesn't exist, it's the dust between the stars and galaxies that causes the effect, as all the dust adds up.
