Five galaxies that appear to orbit each other: This is the Hickson Compact Group 40 captured by Hubble. A billion years from now, they will collide to become one giant elliptical galaxy.
It’s been another year scanning the sky for , who is 32 years old. For this occasion, the reveal a picture Hixon Compact 40 also called HCG40, is a strange group of five . Among them, it is called a galaxy and one . As for the other three, they are in the form of spirals, like .
located in the direction of the constellation : Surrounds the five galaxies in a kind of halo. As a result, they are relentlessly close to each other, By their mutual attraction, but also by the attraction , invisible. Hubble watched them at a crucial moment in their lives, and they’re preparing for it one another. Except that the time scales are not the same for us, because the merger will only happen in a billion years!the array is so compact that it fits into an area less than twice the diameter of our stellar disk . the reason ? The
It’s James Webb’s turn to take charge
Deployed by NASA astronauts into Earth orbit in 1990, it has made over 1.5 million observations of nearly 50,000 celestial bodies! Enough to make great discoveries, like discover, or specify its size and age. today, It prepares to take charge as it continues to calibrate and prepare all of its measuring instruments. Just like its predecessor, the Deep Universe will examine, among all of its objects, those of studying the first moments and formation of galaxies. These could also be in the same state as the HGC40 galaxies, i.e. grouped into dense, compact clusters.
