Record telescope intergalactic collisions



Spitzer Space Telescope and Galaxy Evolution Explorer spacecraft (GALEX) managed to capture the image of intergalactic collision from start to finish. Researchers Harvard Smithsonian Center for Astrophysics who did this observation, Lauranne Lanz, presented the image of the American Society Meeting in Boston.

Two colliding galaxies are NGC 935 and IC 1801. Observational astronomers showed that when two galaxies collide and form larger galaxies, destruction spurred the formation of gas and dust clouds. Furthermore, collisions will spur the formation of more stars.

"This image is the first step to know the story of how galaxies form, evolve, and evolve," said Lanz. According to him, this picture gives a better understanding of what might happen when the Milky Way and Andromeda galaxies collide 5 billion years.

In image retrieval, GALEX ultraviolet rays emit a role to portray the young stars in blue. While the Spitzer telescope which emits infrared light illuminates the heated dust in red. Alloys are two tools that generate rich data.

Lanz said that in every collision of galaxies, the resulting number of stars will vary. Now, he is examining the factors that influence the variation. Lanz also worked hard to test understanding. "Our understanding will really be tested again at 5 billion years the Milky Way had crashed," said Lanz.
