Scientists release largest-ever 3D map of the universe

Scientists release largest-ever 3D map of the universe

Technology
Scientists have released the largest ever three-dimensional map of the universe, proving that it is basically flat and filling in an 11 billion year gap in its history."We know both the ancient history of the universe and its recent expansion history fairly well, but there's a troublesome gap in the middle 11 billion years," said Dr Kyle Dawson. Dr Dawson, a cosmologist at the University of Utah, lead the Sloan Digital Sky Survey (SDSS) team which worked for the past five years to fill in that gap.

Their results were produced in an international collaboration with more than 100 astrophysicists taking part in something called the extended Baryon Oscillation Spectrosco...

Researchers confirm age of universe at 13.8 billion years

Science
July 15 (UPI) -- Studying the oldest available light in the sky, astronomers at a Chilean observatory on Wednesday said they confirmed the universe is about 13.8 billion years old. In two papers submitted to the Journal of Cosmology and Astroparticle Physics this week, the team explained its measurement of the cosmic microwave background, regarded as the oldest light in the universe. Advertisement A 140-person research team from 41 institutions and seven countries, led by Princeton University, published results of a study conducted at the Atacama Cosmology Telescope, located at Cerro Toco in northern Chile's Atacama Desert. The CMB is considered the afterglow of the Big Bang, the foremost explanation about how the universe began. The calculations are in line with estimates made in 2015 wi...

June 25 (UPI) -- With the help of a trio of Hawaiian telescopes, astronomers have imaged the 13-billion-year-old light of a distant quasar -- the second-most distant quasar ever found. Scientists gave the new quasar an indigenous Hawaiian name, Pōniuāʻena, which means "unseen spinning source of creation, surrounded with brilliance." Researchers described the brilliant object in a new paper, which is available in preprint format online and will soon be published in the Astrophysical Journal Letters. Advertisement Quasars are like lighthouses, their beams hailing from far away in the ancient universe. Powered by supermassive black holes at the center of galaxies, quasars are some of the brightest objects in the universe. As astronomers peer deeper into the cosmos, they're able to see what t

Behold the hot, energetic Universe.A German-Russian space telescope has just acquired a breakthrough map of the sky that traces the heavens in X-rays.The image records a lot of the violent action in the cosmos - instances where matter is being accelerated, heated and shredded.Feasting black holes, exploding stars, and searingly hot gas.The data comes from the eRosita instrument mounted on Spektr-RG.This orbiting telescope was launched in July last year and despatched to an observing position some 1.5 million km from Earth. Once commissioned and declared fully operational in December, it was left to slowly rotate and scan the depths of space.eRosita's first all-sky data-set, represented in the image at the top of this pa...
Most powerful supernova in the universe discovered

Most powerful supernova in the universe discovered

Technology
An international team of astronomers has discovered a supernova which is at least twice as bright and energetic, and they believe much more massive, than any other ever spotted in the universe.Led by the University of Birmingham, the team believe the super-supernova, officially named SN2016aps, could be an example of something called a "pulsational pair-instability" supernova produced after two massive stars merged. This extremely rare event has previously been only theoretical, and no astronomical observations had been made which supported its existence until the researchers published their findings in the journal Nature Astronomy. ...
