Sorry, Charlie Brown, NASAof Hubble Space Telescope I was taking a peek at what can best be described as a “big pumpkin”. It looks like a Halloween decoration, hidden in a star-studded sky. It looks like two glowing eyes and a curved sculpted smile, a snapshot of the initial collision between two galaxies.The entire field of view is nearly 109,000 light-years away, approximately our diameter Galaxy.
The overall pumpkin-colored color corresponds to the glow of aging red stars in the two galaxies, which are classified as NGC 2292 and NGC 2293, and they only have a spiral structure. However, because the newly formed clusters of stars spread along a newly formed dusty arm like pearls on a necklace, the smile is slightly red. The glowing eyes are a collection of stars surrounding a pair of supermassive black holes. The scattering of the blue foreground star makes the “pumpkin” look like all the sparkles at a Halloween party.
What’s the matter with this pair of things like pumpkins?
If you mix two fried eggs together, you will get something similar to scrambled eggs. The same is true for galaxy collisions throughout the universe. They lost the flat spiral disk and the stars competed for rugby-like space, forming an elliptical galaxy. However, this pair of interactions is a very rare example, and it may lead to a larger omelette-the construction of a huge spiral galaxy. It may depend on the specific trajectory followed by the colliding galaxy. Astronomers say that encounters must be rare, because there are only a few other examples in the universe.

Researchers say that creating a “smile” ghost arm may just be the beginning of the process of reconstructing the spiral galaxy. The arm contains two galaxies. When two galaxies begin to merge, the interstellar gas is most likely to form when compressed. Higher density will promote the formation of new stars.
The dynamic duo hides 120 million light-years in the constellation Canis Major, so it can be seen far behind the star-filled plane of the Milky Way. Therefore, it is difficult to find distant background galaxies among the many stars seen in the wild.
This pair of galaxies is similar to the objects marked by the citizen science project Galaxy Zoo, where volunteers look for galaxies that look like strange balls. Astronomer William Keel of the University of Alabama in Tuscaloosa has included several of these items in the Hubble Project “Gem of the Galaxy Zoo”, which is in between and other scheduled Hubble observations Observe several rare galaxies within a short interval of. The Hubble telescope image brings new details of close encounters.
Keel speculated that the ultimate fate of the pair of telescopes will be to merge into a huge luminous spiral galaxy, such as UGC 2885, the Rubin Galaxy, whose diameter is more than twice the diameter of our Milky Way. Hubble captured a snapshot of the groundbreaking early stages of the galaxy’s transformation.
The Hubble Space Telescope is an international cooperation project between NASA and ESA (European Space Agency). The NASA Goddard Space Flight Center in Greenbelt, Maryland manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland is responsible for the scientific operations of the Hubble Telescope.
