NASA’s Hubble Space Telescope spies awesome star cluster just 10 mn years old

[ad_1] NASA's Hubble Space Telescope has captured a beautiful image of an open star cluster named NGC 1858 that is just around 10 million years old. Two of the most prominent telescopes run by NASA, the Hubble Space Telescope and the James Webb Space Telescope, keep on clicking stunning images of stars, planets, and more that are out there in space. Recently the Hubble Space Telescope has clicked a beautiful image of an around 10-million-year-old open star cluster named NGC 1858. The cluster is a part of a satellite galaxy of our Milky Way and shows an abundance of star-forming regions. The image was shared by NASA on its Instagram account and by NASA's Marshall Space Flight Center on its Twitter account.Taking to Instagram, NASA wrote in the caption, "An open star cluster northwest p...

Supernova allows us to understand the origin of elements in the universe: Research

[ad_1] A supernova is a stellar explosion, which occurs when the lives of some really massive stars come to an end. A supernova is a stellar explosion, which occurs when the lives of some really massive stars come to an end. In this violent epilogue, the star expels the material from its outer layers by means of a shock wave, allowing us to see the various elements it was composed of.The research team developed a model of the gravitational field of the galaxy that acted as a lens, and that way it was possible to determine that the light from these three images travelled along three different paths, differing in distance by a few days. This accounts for the three colours obtained in the images because a variation in the colour emitted takes place as the gas in the supernova expands an...

Swirling galaxies unite around red quasar in ‘monster’ black hole

[ad_1] Using the James Webb Space Telescope to look back in time at the early universe, astronomers discovered a surprise. Using the James Webb Space Telescope to look back in time at the early universe, astronomers discovered a surprise: a cluster of galaxies merging together around a rare red quasar within a massive black hole. The findings offer an unprecedented opportunity to observe how billions of years ago galaxies coalesced into the modern universe. "We think something dramatic is about to happen in these systems," said co-author Andrey Vayner, a Johns Hopkins postdoctoral fellow who studies the evolution of galaxies. "The galaxy is at this perfect moment in its lifetime, about to transform and look entirely different in a few billion years." The work is in press in Astro...

Tragedy in the making! 2 gigantic galaxies set to crash; NASA Hubble Telescope snaps photo

[ad_1] NASA's Hubble Telescope has taken a horrific photo. 2 gigantic galaxies will crash with tragic consequences for planets. NASA's old flying observatory the Hubble Space Telescope has captured a breathtaking image of a pair of galaxies in deep space that are set to crash into each other with tragic consequences for the planets and suns that are there. The image by Hubble Telescope shows ethereal light from distant stars and galaxies in the background even as the galaxies are seen close to each other. NASA says that these two interacting galaxies making up the pair known as Arp-Madore 608-333 and they seem to be floating side by side in the image. Hubble's Advanced Camera for Surveys had captured this mesmerizing galactic interaction.The space agency has confirmed that these galax...

Hot gas bubble spotted spinning wildly around Milky Way Galaxy black hole

[ad_1] Astronomers said Thursday they have spotted a hot bubble of gas spinning clockwise around the black hole at the centre of Milky Way galaxy at "mind blowing" speeds.The detection of the bubble, which only survived for a few hours, is hoped to provide insight into how these invisible, insatiable, galactic monsters work. The supermassive black hole Sagittarius A* lurks in the middle of the Milky Way some 27,000 light years from Earth, and its immense pull gives our home galaxy its characteristic swirl. The first-ever image of Sagittarius A* was revealed in May by the Event Horizon Telescope Collaboration, which links radio dishes around the world aiming to detect light as it disappears into the maw of black holes.One of those dishes, the ALMA radio telescope in ...

No Gamma rays from a dwarf galaxy solve an astronomical puzzle with the help of NASA

[ad_1] Lack of Gamma rays from a dwarf galaxy have helped to solve an astronomical puzzle of the Fermi bubbles. NASA came to the aid with its Fermi Gamma Ray Space Telescope. A glowing blob known as “the cocoon”, which appears to be inside one of the enormous gamma-ray emanations from the centre of our galaxy dubbed the “Fermi bubbles”, has puzzled astronomers since it was discovered in 2012.In new research published in Nature Astronomy, we show the cocoon is caused by gamma rays emitted by fast-spinning extreme stars called “millisecond pulsars” located in the Sagittarius dwarf galaxy, which orbits the Milky Way. While our results clear up the mystery of the cocoon, they also cast a pall over attempts to search for dark matt...
