7 Best James Webb Space Telescope discoveries of 2023

By Manish Choudhary

1. Ring nebula

The Ring Nebula, found in the Lyra constellation (M57), is a large gas cloud emitted by a dying star transforming into a white dwarf. Situated about 2,500 light-years away, the James Webb Space Telescope offers a detailed view of this planetary nebula.

2. Herbig-Haro 46/47

3. The crab nebula

The Crab Nebula, a supernova remnant in Taurus, sits 6,500 light-years from Earth. In this detailed image, elements like sulphur (in red-orange) and iron (in blue) are highlighted. 

4. Saturn's ring

JWST doesn't just gaze into deep space; it also snapped a cool pic of Saturn in June 2023. The dark look of the planet is thanks to the telescope's near-infrared camera.

5. Herbig-Haro 211

This picture captures energetic gas jets erupting from a newborn star in Perseus, just 1,000 light-years away. The expelled gas collides with others, forming visible shockwaves.

6. Cassiopeia A

Cassiopeia A is the latest supernova remnant in our galaxy, exploding about 340 years ago. This April 2023 mid-infrared image reveals detailed remains of the star, despite being 11,000 light-years away.

7. Rho Ophiuchi

Rho Ophiuchi, a stellar nursery 390 light-years away, is close to our Solar System. It's filled with young stars like our Sun, formed from interstellar dust and gas.
