ESO Used A Galaxy-Sized Magnifying Glass To Capture Two Galaxies Collide 7 Billion Years Ago

Merging galaxies in the distant Universe through a gravitational

If you thought that the Canon 1200mm is big, wait till you see what the ESO (European South Observatory) used to capture two galaxies collide.

Turns out  that if you have the means you can use another galaxy as a lens in a process called gravitational lensing. A gravitational lens is a big (I mean galaxy-big) object in space, when a celestial object aligned behind it, it acts as a lens, bending the light that goes around it, creating a defacto lens.

A Beautiful 4 Years Timelapse Showing A Star Exploding 20,000 Years Ago

v838-monocerotis

While this star exploded about 20,000 years ago (and captured on film starting  12 years ago), NASA has just released a mesmerizing time lapse showing its explosion and death and trippy music.

The star called was captured by the Hubble space telescope “erupting” about 10 years ago, emitting a flash-bulb like burst of light, illuminating the interstellar dust.

Just to get a sense of scale, the image is 13.6 light-years wide, this is not even at the scale of our solar system which is roughly 8 light-hours wide. [Read more...]
