Nearly all the sky is covered by Lyman-α emission around high-redshift galaxies, Published online: 01 October 2018; doi:10.1038/s41586-018-0564-6

Lyman-α emission from atomic hydrogen shows the location of warm gas and is ubiquitous around galaxies between redshifts of 3 and 6, thereby covering nearly all the sky.

Face recognition for galaxies: Artificial intelligence brings new tools to astronomy

A machine learning method called ‘deep learning,’ which has been widely used in face recognition and other image- and speech-recognition applications, has shown promise in helping astronomers analyze images of galaxies and understand how they form and evolve. In a new study, researchers used computer simulations of galaxy formation to train a deep learning algorithm, which then proved surprisingly good at analyzing images of galaxies from the Hubble Space Telescope.

We're all going to die one day, much like these two merging galaxies

We're all going to die one day, much like these two merging galaxiesEverything in the universe comes with an expiration date.  Our planet, for example, will likely be swallowed by the sun in 7 or 8 billion years, when it begins to run out of fuel, heading toward its own death. Milk, on the other hand, spoils after a couple of weeks. And of course, even some of the largest structures in our universe, galaxies, will also die … some in a far more dramatic fashion than others.  SEE ALSO: 2 galaxies merge as 1 in remarkable Hubble Telescope photo Two galactic drama queens located about 350 million light-years away have just started to merge into one, effectively ending their lengthy, cosmic loneliness.  The galaxies, called Arp 256, were spotted in the process of merging by the Hubble Space Telescope, our esteemed eye in the sky since 1990.  “This image suspends them in a single moment, freezing the chaotic spray of gas, dust, and stars kicked up by the gravitational forces pulling the two galaxies together,” the European Space Agency (ESA) said in a statement. “Though their nuclei are still separated by a large distance, the shapes of the galaxies in Arp 256 are impressively distorted. The galaxy in the upper part of the image contains very pronounced tidal tails — long, extended ribbons of gas, dust, and stars.” One day, our Milky Way galaxy will also merge with the Andromeda galaxy. That galactic crash is expected to happen in about 4 billion years. But even in galactic death, there is new life. Gravitational forces have produced new hotbeds of star formation within the galaxies. “The galaxies are ablaze with dazzling regions of star formation: The bright blue fireworks are stellar nurseries, churning out hot infant stars,” ESA said.  “These vigorous bursts of new life are triggered by the massive gravitational interactions, which stir up interstellar gas and dust out of which stars are born.” WATCH: The most massive black holes on record were just discovered 3.5 billion light-years away
