Today’s astronomy photo released by NASA is a stunning snapshot of two colliding galaxies 400 million light-years from Earth.

NASA Astronomy Picture of the Day January 23, 2023: Galaxies are large collections of stars, gas, dust and dark matter held together by gravity. They come in different sizes, from tiny dwarf galaxies with only a few billion stars to giant elliptical galaxies with trillions of stars. Although most galaxies have elliptical shapes, a few have unusual shapes such as toothpicks or rings. Most galaxies exist in groups or clusters with dozens or hundreds of members, and all of these cluster galaxies are in constant motion, being pulled and twisted by the gravity of their neighbors, according to NASA.

Today’s NASA astronomy photo is a snapshot of a stunning pair of colliding spiral galaxies residing in the constellation Virgo, known as Arp 274. Arp 274 is located approximately 400 million light-years away and spans nearly 200,000 light-years. Galaxies have been slowly gravitating toward each other for millions of years. The collision caused galaxies to warp and warp, forming spectacular tidal tails of gas, dust, and stars. The image was taken by Hubble in collaboration with the European Space Agency.

NASA explained

There are two square galaxies in Virgo and here are the latest pictures. When two galaxies collide, the stars that make them up usually don’t. This is because galaxies are mostly empty space, and no matter how bright the stars are, they only occupy a small part of that space. But during a collision, one galaxy can tear the other apart by gravity, and the dust and gas shared by both galaxies collide. If the two galaxies merge, it is likely that what is at each galactic center may eventually merge.

Because the distances are so great, everything happens in slow motion — over hundreds of millions of years. Along with the two large spiral galaxies, a third, smaller galaxy is visible at the far left of the featured image of Arp 274, also known as NGC 5679. Arp 274 spans about 200,000 light-years and lies about 400 million light-years away toward the constellation Virgo.
