NASA's New GIPHY Channel --View Massive Andromeda Galaxy Zooming Towards Collision With The Milky Way
It looks as though that in about three to four billion years, we'll need a new revised, Hitchhiker's Guide to Galaxy. According to recent research the Andromeda Galaxy may be destined to collide with the Milky Way. Right now, the Andromeda Galaxy is barreling toward the Milky Way at 100 to 140 kilometers per second. It’s expected to collide with the Milky Way in about 3.75 billion years.
observations by the Spitzer Space Telescope revealed that Andromeda contains one trillion stars, greatly exceeding the four billion stars in our own galaxy.
This is a fluid-dynamics artist’s rendering of what it’ll look like to a distant observer when the Andromeda galaxy and the Milky Way collide in just under 4 billion years.
