Nearby Barnards Star hosts an icy planet with new hope for alien

first_img Now playing: Watch this: Best places in space to search for alien life Tags The team’s findings are based on over 15 years worth of high-precision observations of Barnard’s Star that’ll be included in an upcoming report in Monthly Notices of the Royal Astronomical Society. Guinan hopes it might be possible to get a better look at Barnard b with the coming generation of very large telescopes. “Such observations will shed light on the nature of the planet’s atmosphere, surface, and potential habitability.” While the exoplanet Proxima b is closer, at only four light-years, it orbits the red dwarf star Proxima Centauri that appears to have a rather rude habit of blasting it with sterilizing solar flares. Barnard’s Star, by contrast, is an older red dwarf and the good news for potential life in its orbit is that powerful flares from the old sun are believed to be a rarity. The bad news, though, is that just such a rare flare was observed from Barnard’s Star only 20 years ago. Hopefully any primitive aliens on Barnard b were able to survive in their geothermal hot tubs under a thick shield of ice. NASA turns 60: The space agency has taken humanity farther than anyone else, and it has plans to go further.Crowd Control: A crowdsourced science fiction novel written by CNET readers. 0 Newfound frigid super-Earth found is the second-closest… Space Post a commentcenter_img 26 Photos 1:31 This doesn’t necessarily curse Barnard b to a lifeless existence, though, according to astrophysicists from Pennsylvania’s Villanova University who say the planet might have a hot liquid iron core producing geothermal energy.”Geothermal heating could support ‘life zones’ under its surface, akin to subsurface lakes found in Antarctica,” Edward Guinan, one of the researchers, said in a statement. The news coincided with the team’s presentation Thursday at a meeting of the American Astronomical Society in Seattle.Any life in such heat pockets would likely be pretty primitive. Scientists are also keen to check for evidence of life in subsurface oceans hidden beneath the frozen shells of Jupiter’s moon Europa and Saturn moon Enceladus.”We note that the surface temperature on Jupiter’s icy moon Europa is similar to Barnard b,” Guinan adds, “but, because of tidal heating, Europa probably has liquid oceans under its icy surface.”    Share your voice Sci-Tech Last year we learned Barnard’s Star, the second closest star system, is circled by a frozen super-Earth. But new research offers hope that at least primitive life might have a warm enough place to survive on the otherwise chilly world. The super-Earth Barnard b (or GJ 699 b) is also the second closest planet discovered beyond our solar system so far, at just six light-years away. Although it orbits Barnard’s Star at about the same distance Mercury orbits our sun, the surface of the planet is likely very cold (-274 Fahrenheit, or -170 Celsius) because the star is a relatively dim red dwarf providing the planet with only about 2 percent of the solar energy we get from our sun.last_img read more

NASA is shooting an asteroid with a giant DART to help save

first_imgNASA’s DART spacecraft will blast off to the asteroid 65803 Didymos to crash into its moon.  NASA If an asteroid was shooting towards Earth, what would our options be? Sure, we could send up a ragtag team of miners to drill into the asteroid, plant a nuke and blast it to smithereens. But if NASA has its way, we won’t need to train miners to be astronauts — it has other plans to deflect those deadly asteroids. (A lucky thing too, because it makes far more sense to teach already-trained astronauts to use a drill rather than putting miners through astronaut school, but that’s another matter entirely). NASA is prepping for a (potential) doomsday outcome with the Double Asteroid Redirection Test — a mission that will test whether we can crash a spacecraft into an asteroid and knock it off course, thus saving humankind and preventing us from ever sending Bruce Willis into space. In this week’s episode of Watch This Space, we take a look at the DART mission to 65803 Didymos — a binary asteroid (complete with its own companion “moonlet”) that’s currently orbiting the sun out past Earth. Now playing: Watch this: NASA wants to save the Earth from asteroids (with a giant… Share your voice According to NASA, the moonlet (or “Didymoon” as it’s been nicknamed) is a perfect example of an asteroid of the size and type that could crash into Earth. So, the space agency wants to send its DART spacecraft up there as early as Dec. 2020 to blast towards the 150-metre-wide moonlet and crash into its surface. Imagine it like a game of pool. If you need to knock the 8 ball in the corner pocket, you knock the cue ball into its side and it’ll shoot off on an angle. By sending its cue ball careening into the moonlet, NASA will measure how the impact changes the moonlet’s momentum and hopefully get a better idea of how asteroids can be redirected in future.To learn more about the DART, the partner mission being run by the European Space Agency and what all this has to do with Elijah Wood and the film “Labyrinth” (there are connections, we promise) then check out this week’s episode of Watch This Space.

5 professors of Rabindra Bharati University resign over caste slurs on woman

first_imgTwitterAfter the Rabindra Bharati University in Kolkata failed to take action against students who harassed an assistant professor over her caste and skin colour, five professors of the university submitted their resignations as a sign of protest.The university’s vice-chancellor, Sabyasachi Basu Ray Chaudhury, is yet to accept the resignations and has called for a meeting with the professors on Wednesday, June 19.On May 20, a group of students had cornered the professor in a room for almost four hours and kept taunting her, making fun of her and spewing verbal abuses regarding her caste and skin colour.However, Trinamool Congress’s student wing president, Chattra Parishad, denied that the students had verbally abused the teacher but said that the teacher was harsh and had allegedly threatened and harassed the students.”A probe has been ordered, and we want it to be completed at the earliest. Anyone found guilty will be severely punished. What happened is a matter of serious concern and Chief Minister Mam ata Banerjee is herself looking into the matter. We could not make contact with the victim professor. I will try and contact her and make her speak with the Chief Minister,” State Education Minister Partha Chatterjee was quoted as saying by Indian Express.Chatterjee had met the professors and the V-C on Tuesday to try and come to a consensus. “I have told the students that if their behaviour made professors feel insulted, they should immediately apologise,” Chatterjee had added.One of the accused students said that did not harass her but asked her why they got so low marks in their test. The teacher in question joined the university as an assistant professor of Geography in September. She hails from Jalpaiguri in north Bengal and studied in Benaras Hindu University and Jawaharlal Nehru University in Delhi.The incident took place on May 20 and she filed a complaint to the university authorities on May 23 after which a committee was formed to investigate the incident.Many professors had stepped up to talk about the incident condemn the way the teacher was treated, first as a woman and as a teacher. However, TMCP maintained that the teacher was harassing the students.TMCP’s Biswajit Dey said, “We trust the probe committee. Let the truth come out. The lady professor used to harass students and threatened to destroy their careers. She was ill-mannered. There were several complaints against her by students. On that particular day, students approached her because she gave abnormally low marks in the examination. No one harassed her.”He added, “The students were agitating and protesting for a long time against private tuition offered by professors, and against the hiring of guest lecturers by HoDs. We also demanded biometric attendance for professors, who are irregular.”last_img read more
