It’s hard to do anything these days without a computer being involved in some way. From credit card readers to traffic signals to the phone in your pocket, computers can perform all kinds of tasks thanks to different software programs. So how did the programmable computer come about? In this animation, we show you how…

Merging galaxies and droplets of starbirth: Hubble snaps a violent galactic merger and chain of star formation

Droplets of star formation and two merging galaxies in SDSS J153

The Universe is filled with objects springing to life, evolving and dying explosive deaths. This new image from the NASA/ESA Hubble Space Telescope captures a snapshot of some of this cosmic movement. Embedded within the egg-shaped blue ring at the centre of the frame are two galaxies. These galaxies have been found to be merging…

VLT Clears Up Dusty Mystery: New observations reveal how stardust forms around a supernova

Artist’s impression of dust formation around a supernova explo

A group of astronomers has been able to follow stardust being made in real time — during the aftermath of a supernova explosion. For the first time they show that these cosmic dust factories make their grains in a two-stage process, starting soon after the explosion, but continuing for years afterwards. The team used ESO’s…

A Stellar Womb Shaped and Destroyed by its Ungrateful Offspring

The Gum 15 star formation region

The little-known cloud of cosmic gas and dust called Gum 15 is the birthplace and home of hot young stars. Beautiful and deadly, these stars mould the appearance of their mother nebula and, as they progress into adulthood, will eventually also be the death of her. This image was taken as part of  the ESO Cosmic…

Alan Turing’s 102nd Birthday – June 23rd

Alan Mathison Turing, b. June 23, 1912, d. June 7, 1954. He played a significant rôle in cracking German codes during World War II, and proposed a test for machine intelligence. He went to King’s College, Cambridge in 1931 to read Mathematics. Turing graduated in 1934, and was a fellow at Kings for two years,…

Swiftly moving gas streamer eclipses supermassive black hole

Supermassive black hole at the heart of NGC 5548

Astronomers have discovered strange and unexpected behaviour around the supermassive black hole at the heart of the galaxy NGC 5548. The international team of researchers detected a clumpy gas stream flowing quickly outwards and blocking 90 percent of the X-rays emitted by the black hole. This activity could provide insights into how supermassive black holes…
