Sci-Tech 0 Post a comment NASA, ESA, STScI, and G. Piotto (Università degli Studi di Padova) and E. Noyola (Max Planck Institut für extraterrestrische Physik) The first stars in the universe are long gone, but their signatures may still be writ across space, buried in gas clouds like space fossils.And scientists believe they’ve uncovered one.Researchers at Swinburne University in Melbourne, Australia used their time at the W. M. Keck Observatory, home to two of the world’s most powerful telescopes, to go on an astro-archeological dig through space. They discovered a “pristine cloud of gas” in the distant universe, seemingly untouched by heavy elements, suggesting it may be a “fossil relic” of the Big Bang.Space fossilsHow do you find a fossil relic in space?Well, the universe has had quite a few birthdays — it’s some 13.7 billion years old. Over that time, a lot of stars have lived and died. At the end of a star’s life, it can sometimes explode, becoming a supernova. This massive explosion spews out a lot of waste heavy elements (metals), so generally when scientists look into space, they often find gas clouds murky with this material. Over 13.7 billion years, a lot of stars have exploded — so there’s a lot of waste in the clouds.Examining these gas clouds allows for scientists to gather insight on some of the earliest events in the universe. If the gas clouds are unspoiled by the waste, they may have existed in the infant universe. The research team think they’ve identified one that’s practically untouched by waste heavy elements.”Our inspiration is actually to find relics of the first stars in the universe,” said Prof. Michael Murphy, one of the lead researchers on the study. Gas clouds that are relics of the first stars would be “almost pristine”, according to Murphy, so there would still be traces of the heavy element waste within them.But the fossil relic they found had no detectable levels of waste — it was completely clean — suggesting it comes from the very early universe and has been untouched for 1.5 billion years after the Big Bang.”This discovery – a seemingly pristine cloud – is really important,” said Murphy. “We need to know whether such clouds can last billions of years without being polluted by multiple generations of stars.”Before this discovery, only two such gas clouds had been discovered — and those discoveries were mostly accidental. By actively seeking out the gas clouds and demonstrating that they are unspoiled by heavy elements, Murphy’s team has shown that it’s possible to go digging for them.”Now we’ve proven that we can systematically find such fossils, we really have a chance of knowing how rare or common they are,” said Murphy. “That’s crucial for testing our understanding of how the first galaxies formed.”The first starsIt’s not the first time these relic gas clouds have proven fruitful for Swinburne researchers. In 2016, the team discovered an “almost pristine” gas cloud using data from the Very Large Telescope in Chile.”It proved that trying to hunt for these clouds – and the completely pristine clouds like the one we’ve now discovered – in a targeted way was feasible and could, in principle, identify a “smoking gun” signature of the first stars,” said Murphy.However, there may be alternate explanations for why the gas cloud is so clean — and those explanations are exciting, too.One possibility is that the cloud is polluted by one of the universe’s first stars, leaving only traces of heavy elements, undetectable by the telescopes the team used. Another is that the gas cloud is moving through a galaxy for the very first time, so it has yet to be polluted by other stars just yet.”This is an exciting possibility because understanding how such gas clouds ‘feed’ galaxies is a major problem in astrophysics,” explained Murphy.”We’d like to test this possibility by mapping any galaxies near the cloud in future.”And so searching for the earliest signatures scribbled across the cosmos continues.

BJP cant win polls by conducting riots playing communal card

first_imgKharagpur: In a scathing attack on BJP, Trinamool Youth Congress president Abhishek Banerjee said the party cannot win the Lok Sabha elections by conducting riots, playing the communal card or highlighting fake nationalism.He was addressing a mammoth rally here on Tuesday afternoon. “BJP is trying to win the elections by conducting riots or by using fake nationalism. Bengal has a different culture and no one can gain anything here by playing the communal card,” he said. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataBanerjee alleged that the BJP leaders who are coming for election campaigns are all harping on the communal agenda to divide the Hindu and Muslim communities. “BJP sells Hinduism to win elections and with this in mind, spreads hatred against the Muslims. This is most unfortunate. Religion is private and in social life our only philosophy is to serve the people,” he added. Banerjee said the 2019 Lok Sabha election is “not a fight between Trinamool and BJP. It is a fight between Bengal’s rich tradition and culture on one side and the Centre’s extortion on the other.” Also Read – Lightning kills 8, injures 16 in stateHe alleged that BJP has looted the country in the past five years. “You will not hear a single word from them on note ban which was implemented to stop black money and terrorism. BJP does not say anything on the hasty implementation of GST either, along with farmer suicides and why 2 crore people lost their jobs. They only talk on religion to incite one community against the other,” the Trinamool Youth Congress president stated. Banerjee urged people to cast their votes in favour of party nominee Manas Bhuniya. “Undivided Midnapore had played a major role in the freedom movement. In 2019, the district will play a major role in driving out the Modi government. On May 23 when the ballot boxes will be opened, people will see that Trinamool Congress has bagged 42 out of 42 seats,” he said. He also urged people to visit the polling stations early and exercise their franchise.last_img read more

Eighthour sleep may boost academic performance

first_imgWorried that your son or daughter sleep more even during final exams week? If so, take heart. According to a study, students who sleep for eight hours are more likely to perform better. “Better sleep helped in final exam performance, which is contrary to most college students’ perceptions that they have to sacrifice either studying or sleeping,” said Michael Scullin, Assistant Professor at Baylor University’s College of Arts and Sciences. Also Read – Add new books to your shelfFor improvement in academic performance, a student does not have to be an ‘A’ grade, the researchers said. The findings showed that whether a student was an A, B, C, or D student before their final exam, sleeping eight hours was associated with a four-point grade boost. “It is worth noting that one student who had a D-plus grade before the final but slept more than eight hours for a week during finals week remarked that it was the first time her brain worked while taking an exam,” Scullin said. Also Read – Over 2 hours screen time daily will make your kids impulsivePoor sleep is common during finals as students cut back on sleep, deal with more stress, use more caffeine and are exposed to more bright light, all of which may disrupt sleep. Fewer than 10 per cent of undergraduates maintain the recommended average of 8 hours a night or even the recommended minimum of 7 hours, the researchers said. In the study, the students were given extra points if they met “the 8-hour Challenge” – averaging eight hours of sleep for five nights during final exams week. The participants included undergraduate interior design students and students in upper-level psychology. They wore sleep-monitoring wristbands for five days for accurate results.last_img read more
