THE CARTWHEEL IN SPACE
BBC Sky at Night Magazine
|October 2022
Another stunning image from the largest space telescope ever launched shows just what this new observatory can do
-
The wonderful Webb Space Telescope delivers again, with this image of the Cartwheel Galaxy in the constellation Sculptor, and its companions, taken using both the scope's near-infrared and mid-infrared cameras.
Formed by a galactic collision 400 million years ago, the Cartwheel Galaxy has a bright inner ring and colourful outer ring, both expanding outward from the centre.
Before the collision shattered it into these beautiful rings, the Cartwheel was a spiral galaxy, and you can see the remains of its arms in the 'spokes' that connect the rings and give the galaxy its name. The red colouration comes from glowing dust rich in hydrocarbons, while the blue dots are Epockets of star formation.
A new star's home
