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.

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.

With this new effort, the scientists discovered a number of surprisingly bright very young galaxies . One of these, called CR7, was an exceptionally rare object; it was the brightest galaxy ever seen at this stage in the universe. While these findings were exciting, the researchers went further and also

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.

Researchers encode a movie onto living bacteria

  Researchers encode a movie onto living bacteria What if you could carry your iTunes library in your skin?The team inserted a short animated image of 'The Horse in Motion' (one of the earliest moving images ever created) into E. coli, using gene-editing system CRISPR. The movie was split into five frames, and each frame chopped into single-colored pixels. They then created DNA codes corresponding to each color and strung them together. Each bacterium carried snippets of the video stored in their DNA, and when taken together, the scientists were able to retrieve and reconstruct the pieces to play the video.

NASA's Hubble Space Telescope, with a boost from a natural "zoom lens," has uncovered what may be one of the youngest and brightest galaxies ever seen in the middle of the cosmic "dark ages," just 700 million years after the beginning of our universe.

A team of US researchers completed work on a comprehensive map of the human epigenome. CR7 is the brightest galaxy discovered by science to date, emitting light equivalent to that of 300 trillion suns. Here are some of the most amazing ideas and inventions we have ever seen .

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."

New Exoplanet-Hunting Instrument Provides Wider View of the Night Sky .
MASCARA's cameras take repeated calculations of the brightness of stars all across the evening sky , and if its software detects that the light dimmed and then brightened, scientists can deduce that a planet may exist and might have passed in front of the star.MASCARA will have its deep gaze set on finding star systems with planets known as "hot Jupiters." These gas worlds are about the same size as Jupiter, but unlike that planet, they orbit quite close to their parent stars and have high surface temperatures.
