Astronomy Science ~ With a distance of about 60 million light-years away in the constellation Corvus, two large galaxies are colliding.

The stars in the galaxy known as NGC 4038 and NGC 4039, very rarely collide due to the collision between the two galaxies is very slow, lasting hundreds of millions of years. But a large cloud of gas and dust often large molecules collide, triggering the formation of intense star formation near the center of cosmic debris.

The antenna is a pair of spiral galaxies interacting and mingling their stars. They began their galactic dance more than a few hundred million years and are currently in a period when their collision gas clouds are full of new star formation. As the two galaxies merge, their gravitational interactions have long tails of gas away from each other, and these queues are star business sites. In a few million years, the nuclei of the two galaxies will merge into a single nucleus with a supermassive black hole at its center. It will be surrounded by an elliptical galaxy of old stars.

Profile Galaxy

Description: NGC 4038 / NGC 4039
Type: Interacting Spirals
Diameter: hundreds of thousands of light years
Distance: 45-64000000 light years
Group: Virgo Cluster

Facts Antennae Galaxies :
  1. Spiral galaxies are combined as the antennas are more likely to end galaxies.The time to melt as elliptical, all traces of its spiral arms will be deleted.
  2. It is likely that when the Milky Way and Andromeda galaxies are combined, which will be similar to the antennas for at least one point of their interaction.
  3. Of the millions of new stars that is created when merging Antennae, only ten percent of them live more than 10 million years. This is because they are massive blue supergiant, a type of star that quickly consumes its nuclear fuel and explodes as a supernova.
  4. The young massive star clusters formed during the remaining Starburst activity become globular clusters of the new galaxy.
  5. The Antennae galaxies are closer colliding galaxies to the Milky Way.
This composite image spans an area of 500 thousand light years also reveals new star clusters and matter flung far from the scene of the accident by gravitational tidal forces.

Because of the long arc structure view, this galaxy has a pair of popular names as The Antennae (Antenna).
