Astronomers study the nature of galaxy NGC 891 with the James Webb Space Telescope

  • No comments
The diameter of the galaxy is about 100,000 light years and it is classified as a normal star-forming spiral galaxy, with similarities to the Milky Way but with a slightly higher global star formation rate
This "penguin party" is loud. The twisted spiral galaxy in the center, known as the Penguin, and the compact elliptical galaxy to the left, known as the Egg, are in an active embrace. A new near- and mid-infrared image from the James Webb Space Telescope, taken to mark two years of scientific activity, shows that their interaction is marked by a subtle, inverted U-shaped blue glow.

Researchers speculate that the penguin had the shape of a spiral. Today, its galactic center shines like an eye, its disordered arms now shaping as a beak, head, spine, and spread tail. The elliptical galaxy that looks like

This artist's illustration shows a collision between two bodies of ice and dust orbiting the bright star Pomelhot, 25 light-years away. This may have caused an expanding cloud of very fine dust particles. Credit: ESA, NASA and M. Kornmesser

The belts surround the hot young star, which can be seen with the unaided eye as the brightest star in the southern group Southern Pisces. The dust belts are debris from the collisions of larger bodies, corresponding to asteroids and comets,
A star exploding is a dramatic event, but the debris the star leaves behind can be even more dramatic. A new mid-infrared image from the James Webb Space Telescope provides one stunning example. It shows the remains of the supernova Cassiopeia A (Cas A), created by a stellar explosion 340 years ago. The image shows bright colors and complex structures. Cas A is the youngest known remnant of a massive exploding star in our galaxy, offering astronomers an opportunity to understand the star's death process. Image credit: NASA, ESA, CSA, D.

Webb recorded what remained after the death of a star only 11 thousand light years away from us. It is a relatively new supernova - only 350 years old
