Galaxies Collide to Create Hot, Huge Galaxy

7 posts in this topic

Posted (edited)

Hearts of Galaxies Close in for Cosmic Train Wreck‏

This image of a pair of colliding galaxies called NGC 6240 shows them in a rare, short-lived phase of their evolution just before they merge into a single, larger galaxy. The prolonged, violent collision has drastically altered the appearance of both galaxies and created huge amounts of heat -- turning NGC 6240 into an "infrared luminous" active galaxy.

A rich variety of active galaxies, with different shapes, luminosities and radiation profiles exist. These galaxies may be related -- astronomers have suspected that they may represent an evolutionary sequence. By catching different galaxies in different stages of merging, a story emerges as one type of active galaxy changes into another. NGC 6240 provides an important "missing link" in this process.

This image was created from combined data from the infrared array camera of NASA's Spitzer Space Telescope at 3.6 and 8.0 microns (red) and visible light from NASA's Hubble Space Telescope (green and blue).

Here ya go Dr.

Which is the biggest Galaxy in the Universe?

In: Astronomy

The largest galaxy on record resides inside the Abell 2029 cluster, 1.07 billion light years away in the constellation of Serpens. Designated as IC 1101, the monstrous giant elliptical galaxy measures a whopping 6 million light years (as compared to the 100,000 ly of the Milky Way) in diameter and is said to be at least 60 times as large as the Milky Way. It also contains about 100 trillion stars (200-400 billion for the Milky Way).

hey, thanks :tu:

thats bigger than i expected. i wouldce thought that it woulve been less than a million light years across. but 6 MILLION :o . WOW!

Isn't our very own milky way made up of a number of galaxies that have collided over billenia (if that's a word) i know our galaxy neighbours orbiting our milky way will one day collied with us has we all group together and eventually collide with the Andromeda galaxy on our way to Virgo. I'd love to witness the day/night sky when Andormeda approaches. it would be a sight for sore eyes alright.

1o million years

it turns out that the little ones are not orbitting the milky way just passing by

Are you inferring that the Milky Way is stationary or just going slower and that there may be another on the way?
