There are probably more than 170 billion galaxies in the observable universe. 11. As far as the categorization of these galaxies is concerned, they are no longer spiral galaxies. Almost 40 feet long! It will be surrounded by hundreds of stars, each with their own planetary systems. The two spiral galaxies started to interact a few hundred million years ago, making the Antennae galaxies one of the nearest and youngest examples of a pair of colliding galaxies. An arch of stars that have been pulled from other galaxies shows up as a bright blue, red and hot pink corona around the colliding galaxies. The mysterious component called dark matter makes up the remaining unknown part of this starry mix. At least two supernovas have been observed in the colliding galaxies, in 2004 and 2007, respectively.Images from the Hubble Telescope confirm the Chandra observations. View. Distance from Earth: 68 million light-years. Before the collision of the two galaxies, one was larger than the other. He built more than 400 over his lifetime but made one that changed the world. 9. The age of these new stars will not last longer because they will be huge blue supergiants, a type of star that quickly consumes its nuclear fuel and explodes as a supernova. 7.

Examples of galaxies range from dwarfs with as few as ten million stars to giants with a hundred trillion stars or more, each orbiting through their galaxy. These photos show what appears to be a stormy cosmic dance between stars with gas clouds that are being pulled from other galaxies as they collide against each other. The Antennae Galaxies have two orange blobs. The collision, with its clouds of gas, dust and magnetic fields, causes extremely rapid star formation.This is their starburst phase, and might last a few hundred million years. The globular clusters will likely originate from shockwaves, generated by the galaxies collision, compressing large, massive molecular clouds.

These Antennae Galaxies have a massive diameter which extend to hundreds of thousands of light years. 5. Scientists have predicted that when the Milky Way collides with Andromeda, an intense burst of light will be produced with a similar outcome as above. by NASA Marshall Space Flight Center. They are currently going through a starburst phase, in which the collision of clouds of gas and dust, with entangled magnetic fields, causes rapid star formation. After carefully examining and analyzing their data for years, scientists concluded that they were either super star clusters or neutron stars because black holes emit no light. This mixing together between the galaxies began over 3 hundred million years ago. The Planets. These images show what appears to be a stormy cosmic dance of stars, gas clouds, dust and light. Angular Size The Antennae Galaxies is therefore larger than our home galaxy. About NGC 4038 and NGC 4039. These two galaxies are colliding at this very moment and have attained a weird shape. It is the collision and merging of two Spiral galaxies that is both destroying them and creating thousands of new stars at the same time. The Antennae Galaxy was originally thought to be 63 million light-years from Earth, but research in 2008 from the Hubble Telescope now puts it at a much closer 45 miles. When the merger between the two galaxies gets completed, they will possibly give rise to a Giant Elliptical galaxy. 13. William Herschel, the British astronomer who discovered Uranus in 1781, also made an incredible discovery of two colliding galaxies that were previously unknown to science. Also known as: NGC 4038 (upper galaxy) and NGC 4039 (lower galaxy) Type of object: Spiral galaxies. They are in the constellation Corvus.The process takes hundreds of millions of years, maybe even a billion years. The merger or the collision actually started a few hundred million years ago. Formally known as NGC 4038 and NGC 4039, the pair is nicknamed the Antennae Galaxies because of two long streamers of stars, gas, and dust that extend from the crash site. The ejected stars of the galaxies extend much farther away and beyond the original galaxies and results in its antenna shape. In the future, the Milky Way and Andromeda galaxies likely will combine and look similar to the Antennae during at least one point of their interaction. Antennae Galaxy Facts.
