Hubble Captures New Star Images With Help From Gravity

  Hubble Captures New Star Images With Help From Gravity The galaxy in question appears as it was 11 billion years ago, just 2.7 billion years after the Big Bang. "When we saw the reconstructed image we said, 'Wow, it looks like fireworks are going off everywhere,'" astronomer Jane Rigby of NASA's Goddard Space Flight Center in Greenbelt, Maryland, said in a statement.Astronomers have used the Hubble Space Telescope, taken advantage of a natural phenomenon and applied new computational methods to capture closer-up and more detailed images—about 10 times sharper than they could with the telescope alone.

  Researchers discover one of the brightest galaxies ever seen © Provided by Engadget Scientists at the Instituto de Astrofisica de Canarias, a research institute in the Canary Islands, just discovered one of the brightest galaxies we've ever come across. It's around a thousand times brighter than our galaxy, has a very high rate of star formation and is 10 thousand million light years away.

The researchers found the galaxy using the gravitational lensing effect wherein really massive objects in space, like galaxies or galaxy clusters, warp and enhance the light of smaller objects nearby. This phenomenon has helped researchers track down exoplanets, black holes and unexpected galaxy types. This discovery, which was recently published in the Astrophysical Journal Letters, was made possible by a galaxy cluster that lies in between us and the newly observed bright galaxy. "Thanks to the gravitational lens produced by a cluster of galaxies between ourselves and the source, which acts as if it was a telescope, the galaxy appears 11 times bigger and brighter than it really is, and appears as several images on an arc centred on the densest part of the cluster, which is known as an "Einstein Ring," Anastasio Díaz-Sánchez, an author of the article, said in a statement.

Apple launches a machine learning blog to placate its researchers

  Apple launches a machine learning blog to placate its researchers Apple hasn't always been very open about its technology or its research, but the company surprised everyone last year when AI director Russ Salakhutdinov announced that Apple would begin publishing its machine learning research. In a short welcome post on the new blog, the company said, "Here, you can read posts written by Apple engineers about their work using machine learning technologies to help build innovative products for millions of people around the world." And the post encourages researchers, students, engineers and developers to contact the journal with any questions or feedback.

The light amplification and multiple images of the galaxy produced by the gravitational lensing effect helped the scientists see the galaxy and will help them analyze more details about its composition in the future. The researchers have dubbed this galaxy the Cosmic Eyebrow because of the similarities to another galaxy called the Cosmic Eyelash. That galaxy got its name because it was found near a young galaxy called the Cosmic Eye, which looks like its namesake due to its image being warped by gravitational lensing.

The Cosmic Eyebrow, which because of its distance we're seeing the earlier stages of, will help researchers understand the formation of large distant galaxies and how they evolve into elliptical galaxies that exist today. Susana Iglesias-Groth, another author of the study, said, "This type of objects harbour the most powerful star forming regions known in the universe. The next step will be to study their molecular content."

The perfect crime foiled by... a mosquito

  The perfect crime foiled by... a mosquito The murderer absconds with a smirk, knowing he has covered his tracks like a pro.But if a mosquito bit our cocky assassin at the crime scene, it could one day lead to a conviction, according to study published Monday in the journal PLOS ONE.

As if the present galaxies are not wondrous and bright enough – The Milky Way, The Andromeda, Sombrero, Centaurus – so many to name, yet another galaxy has been discovered by NASA’s Wide-field Infrared Survey This dazzling light is said to be the main growth spurt of the galaxy ’s black hole.

It’s about a thousand times brighter than the Milky Way. An excess of 'failed' stars is a bad sign for alien life. There could be 100 billion brown dwarfs in our galaxy , many more than thought.

Medieval Mummies from Lost Arctic Civilization Found .
Remains of a baby and an adult dating back 800 years were found in burial cocoons at the archaeological site.Excavations at Zelenyy Yar ended last week and over the course of this year’s expedition to the Arctic site, scientists found 10 graves. Five of these had not been looted for their grave goods—valuable objects placed with bodies in ancient burials.
