Webb Telescope

First image. Imagine holding a grain of sand at arms length. That's the size of the patch of sky expanded in this image.

This is the galaxy cluster SMACS 0723.

Here is the same patch of sky from the Hubble Telescope.

It's a giant leap forward in resolution and light gathering power.

The level of detail in the small galaxies, and the blatantly obvious gravitational lensing, has me very impressed and excited about what we are going to discover with this telescope.

I mean seeing friggin dust lanes and spiral arms, in galaxies that far away, is just incredible.

Light from 13 ... thirteen ... billion years ago.

What an upgrade to Hubble. The amount of detail and number of galaxies in this photograph is incredible.

Amid an enormous cloud of dust and gas, thousands of stars are forming. Many of these stars have never been seen before, but these images from the James Webb Space Telescope (JWST) are revealing them for the first time.

These pictures show the Tarantula Nebula, located about 161,000 light-years away in the Large Magellanic Cloud – a galaxy that orbits the Milky Way. The nebula is the biggest and brightest one in all the nearby galaxies, and hosts some of the hottest and most massive stars astronomers have ever seen.

The massive young stars that form a sparkling blue cluster near the centre of the above image have cleared out the gas around them with their powerful radiation and intense stellar winds, revealing pillars of relatively dense gas inside which more young stars are forming. The above image was taken with JWST’s Near-Infrared Camera (NIRCam), showing the dusty filaments that make up the web of the Tarantula Nebula.
