NASA discovers a surprisingly massive galaxy cluster 2 billion years earlier than supposed

Two powerful NASA observatories looked deeply into a patch of sky and found a galaxy cluster forming only about one billion years after the Big Bang. Scientists never expected to find something as massive as a galaxy cluster at such an early time in the universe’s existence.

Webb's 255-hour-long observation reveals invisible dark matter in a map area containing nearly 800,000 galaxies

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.

Webb finds the first conclusive evidence to explain a mind-puzzling mystery

Using NASA’s James Webb Space Telescope, scientists have found the forging site of crystalline silicates. They also discovered how these particles are possibly distributed. The study provided evidence to explain how cold comets get to contain crystalline silicates β€” particles that need intense heat to form.

Webb zooms in on the Helix Nebula to see what happens around a dying star

NASA’s James Webb Space Telescope provided a detailed image of the Helix Nebula. The high-resolution image revealed the structure of the gas being shed off from the dying star. With this image, astronomers can see how stars recycle their material into the cosmos.
