As the name suggests, this galaxy may look like the wheels of a wagon to some.
The Cartwheel Galaxy and the galaxies to its left are part of a cluster of galaxies in the Sculptor star cluster, about 500 million light-years from Earth.
Right Image A rare and spectacular head-on collision between two galaxies appears in this Hubble Space Telescope true-color image of the Cartwheel Galaxy, located 500 million light-years away in the constellation Sculptor. The new details of star birth resolved by Hubble provide an opportunity to study how extremely massive stars are born in large fragmented gas clouds. Top Left Image Hubble’s detailed view shows the knot-like structure of the ring, produced by large clusters of new star formation. Hubble also resolves the effects of thousands of supernovae on the ring structure. One flurry of explosions blew a hole in the ring and formed a giant bubble of hot gas. Secondary star formation on the edge of this bubble appears as an arc extending beyond the ring. Bottom Left Image Hubble resolves remarkable new detail in the galaxy’s core. The reddish colour of this region indicates that it contains a tremendous amount of dust and embedded star formation. Bright pinpoints of light are gigantic young star clusters.
The diameter of this galaxy is about 10000 light years…!! It also contains many giant stars and newly formed baby stars.
The ring-like features seen inside the Cartwheel Galaxy are formed by the gravitational pull of nearby baby galaxies.
Researchers analyzing the Hubble Space Telescope’s dramatic pictures of the Cartwheel galaxy have discovered immense comet-like clouds of gas speeding through the heart of the galaxy at nearly 700, 000 mph.
Thus, when a baby galaxy passes in front of the Cartwheel Galaxy, it exerts a gravitational influence on the gas sheets where new stars are being formed, resulting in ripples like a pebble falling into a still pond.
This image taken by James Webb gives us information about the birth of new stars and the events surrounding the black hole inside them.
The Solar System proxima century next to our solar system is a smaller star than the Sun, but it is said that we can not see it with the naked eye. It is 4.5 light years away from our Earth....
Closest black hole to Earth discovered. The black hole, named Gaia BH1, is located 1560 light-years from Earth. This black hole exists by partnering with a star. The distance between this star and the black hole is similar to the...
