New YearIt’s gone, but it’s a good idea to fire a New Year’s celebration in this way. The 6 images introduced here areNASAIs published by ESAHubble Space TelescopeByTetraIt is a figure in which the obtained galaxy collides with the galaxy.
When galaxies collide with each other, a terrifyingly dense and bright region of stars is created. Such “Star clusterThe spot called “is where we liveMilky Way GalaxyIn, it has 10,000 times the mass of the sun. But these galaxy collisions weigh millions of times more than the Sun.

Oxygen molecules are detected for the first time in galaxies other than the Milky Way
It is suggested that there may be at least 36 advanced extraterrestrial civilizations in our galaxy.
The brilliance of galaxy collision
The brilliance of collisions between galaxies continues to illuminate the galaxies as witnesses to the once-occurring fusion phenomenon, even after the galaxies have regained their composure after the collision.
These star clustersUltraviolet rayscameraAnd nearInfraredcameraBy observing with, the age and mass are estimated, and how much therepaceYou can see if the stars are born at.
However, it unravels the mystery of when the entire star system was born.puzzleIt’s just one piece of.
These images areYear 2008From2020OctoberIt was taken over.
Peculiar galaxy “NGC 3256” 100 million light-years away from the earth
A peculiar galaxy 100 million light-years away from EarthNGC 3256“.The fusion of galaxies once created such a distorted appearance.
Galaxy “NGC 1614” 200 million light-years away
EridanusA galaxy 200 million light-years away in the direction ofNGC 1614 “. Also known as The River.
A galaxy collision creates a turbulent flow of interstellar gas from a small galaxy caught in the core of the larger galaxy, causing explosive star formation that began in the nucleus to move outside the galaxy.slowlyIt spread.
From its appearance, a peculiar galaxy,StarburstIt is classified as a galaxy.It shines very strongly, 200 million500It is the second brightest galaxy in the range of 0,000 light-years.
“NGC 4194” 130 million light-years away
Ursa MajorDirection, 100 million300“0,000 light-years away”NGC 419“4” is composed of two galaxies that collide and coalesce. Also, explosive star-forming regions caused by galaxy interactions can be seen in the central part of the galaxy. It was formed by a young galaxy swallowing a smaller galaxy and releasing stars and dust.

The center of the shining galaxyMedusaEyes that can turn a person into a stone. The tail of the star stretched by the tidal force of the galaxyMedusaSnakehairRepresents.
“IC 694” and “NGC 3690” that passed 700 million years ago
“IC 694” and “IC 694” that passed each other about 700 million years agoNGC 3690 “. This encounter prompted the formation of explosively fierce stars.

Collision galaxy pair “NGC 6052”
HerculesDirection, 200 million300It is beyond 0,000 years later. The shape of this irregularly distorted galaxy indicates that two galaxies collide and merge, and when separating each galaxy, “NGC 6052A 」NGC 605Call it “2B”.
Cetus collision galaxy “NGC 34”
CetusIn the direction of “NGC “34” is about 270 million light-years away.In the bright area of the center, galaxy collisions have spawned a number of new stars, illuminating the surrounding gas.
