First ‘bone’ of the Milky Way identified

first_imgAstronomers have identified a new structure in the Milky Way: a long tendril of dust and gas that they are calling a “bone.”“This is the first time we’ve seen such a delicate piece of the galactic skeleton,” says the lead author Alyssa Goodman of the Harvard-Smithsonian Center for Astrophysics (CfA). Goodman presented the discovery Jan. 8 in a press conference at a meeting of the American Astronomical Society in Long Beach, Calif.Our Milky Way is a spiral galaxy — a pinwheel-shaped collection of stars, gas, and dust. It has a central bar and two major spiral arms that wrap around its disk. Because we view the Milky Way from the inside, its exact structure is difficult to determine.Internal bones, or endoskeletons, have been seen in other spiral galaxies. Observations, especially at infrared wavelengths of light, have found long, skinny features jutting between galaxies’ spiral arms.  These relatively straight structures are much less massive than the curving spiral arms.Computer simulations of galaxy formation show webs of filaments within spiral disks.  It is very likely that the newly discovered Milky Way feature is one of these “bonelike” filaments.Goodman and her colleagues spotted the galactic bone while studying a dust cloud nicknamed “Nessie.” The central part of the Nessie bone was discovered in Spitzer Space Telescope data in 2010 by the astronomy professor James Jackson of Boston University, who named it after the Loch Ness Monster. Goodman’s team noticed that Nessie appeared at least two times, and possibly as much as eight times, longer than Jackson’s original claim.Radio emissions from molecular gas show that the bone is not a chance projection of material on the sky, but instead a real feature. Not only is Nessie in the galactic plane, it extends much longer than anyone anticipated. This slender bone of the Milky Way is more than 300 light-years long but only 1 or 2 light-years wide. It contains about 100,000 suns’ worth of material, and looks like a cosmic snake.“This bone is much more like a fibula — the long skinny bone in your leg — than it is like the tibia, or big thick leg bone,” explained Goodman.“It’s possible that the Nessie bone lies within a spiral arm, or that it is part of a web connecting bolder spiral features. Our hope is that we and other astronomers will find more of these features, and use them to map the skeleton of the Milky Way in 3-D,” she added.last_img read more

Who is Chelsea’s best centre-back?

first_imgChelsea’s defence has had its problems of late but manager Roberto Di Matteo is not short of options, with four quality centre-backs vying for two places in the Blues side.John Terry will soon return from suspension and will perhaps have a point to prove, with some pundits suggesting he is well past his best and may no longer be a first-choice defender.Gary Cahill seems to grow in stature with each game, producing assured performances both against European opposition and during the cut and thrust of Premier League football.Branislav Ivanovic of course operates at right-back much of the time, but his outstanding performances when moved to central defence suggest that remains his best position. Physically strong with excellent positional sense, the Serbian is a great option to have.David Luiz will probably always have his doubters and like many centre-backs in his mould, mistakes creep in and attention focuses on his shortcomings. But he remains a class act and, the odd setback aside, continues to look more at home in the Premier League.So which of the four do you believe is Chelsea’s best centre-back?[poll id=”33″] See also:Boss backs Terry after leaving him out 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 Follow West London Sport on TwitterFind us on Facebooklast_img read more

Africa’s bloggers set own agenda

first_img7 May 2015More than 1 000 entries from across the African continent were received for the 2015 African Blogger Awards – more than double the number received in 2014, the inaugural year.The awards aim to acknowledge talented Africans making their mark in the online space.Entries were open in five main categories including Best African Blog, Best African YouTube Channel, Best African Instagrammer, Best African Twitter profile and Best African Facebook page, as well as across 36 sub-categories.The awards are based on “impartial blog metrics”, rather than through peer nominations and voting, the organisers say.“The extensive growth in the number of entries we received this year shows that the African social influencer and blogging scenes are not as far behind the rest of the world as many people think,” says Murray Legg, co-founder of the African Blogger Awards.“Even though blogs created and built in Africa may be slowed down by irregular connectivity, it’s clear that content is being spread across social networks like wildfire, as people across the continent use social media to connect and share their stories,” Legg said.The organisers say that social media has allowed the continent to take charge of its own narrative. “It is always amazing to see the power of social media, especially in telling a good news story about Africa, take center stage in the digital age.”The winners were announced on 5 May, with awards made in four of the five main categories:The best blog about Africa is The African Hip Hop Blog from ZimbabweThe best Instagrammer in Africa is Gareth Pon from South AfricaThe best Twitter personality in Africa is Xtiandela from KenyaThe best YouTube channel in Africa is a href=”https://www.youtube.com/theodora” target=”_blank”>Theodora Lee from South AfricaThe 36 sub-categories included advice, fashion and beauty, events and nightlife, education, sports, political, technology and gadgets, and youth culture.Category winners include:Advice: Kenya Weddings followed by The Techie Guy from South AfricaArts and Culture: 10and5 (South Africa) followed by Another Africa from EritreaBrand Blog: Ellerman House (South Africa) followed by Bona (South Africa)Business: TechFinancials (South Africa) followed by Mark Lives (South Africa)DIY blog: The Pretty Blog (South Africa) followed by Make Money Online (Nigeria)Entertainment: YoMzanzi (South Africa) followed by Book of Swag (South Africa)Events and Nightlife: Just Curious (South Africa) followed by DK Expressions (South Africa)Expat Living in Africa: Journal of a City Girl (Namibia)Fashion and Beauty: Superficial Girls (South Africa) followed by Inspired Living (South Africa)Food and Drink:Pika Chakula(Kenya), followed byHein Stirred(South Africa)Health and Beauty: Healthable (Nigeria) followed by Not Another Poppie (South Africa)Hobbies: Lazy Gamer (South Africa) followed by Vamers (South Africa)Lifestyle: Lovilee (South Africa) followed by Inspired Living (South Africa)Marketing and Media: Techloy (Nigeria) followed by GottaQuirk (South Africa)Music: Running Wolf Rant (South Africa) followed by Texx and the City (South Africa)Parenting: The Blessed Barrenness (South Africa) followed by Rattle and Mum (South Africa)Personal: Dad and the Code (South Africa) followed by Lucky Pony (South Africa)Photography: Mooi Troues (South Africa), followed by Fire fly Africa (South Africa)Political: Josephat Lukaza (Tanzania) followed by Synapses (South Africa)Specific to Your Country: Kenya Weddings followed by Don’t Party (South Africa)Sports: The Pundits (South Africa) followed by The Bounce (South Africa)Technology and Gadgets: PixelVulture (South Africa) followed by TechLoy (Nigeria)Travel: The Travel Manuel (South Africa) followed by Duff’s Suitcase (South Africa)Youth Culture: Don’t Party (South Africa) followed by Book of Swag (South Africa)The awards said on its website that the event had been enthusiastically covered on social media, where “the diversity of nationalities [were] a clear indication that social media influencers across Africa have welcomed the opportunity to be measured quantitatively against their peers. The African Blogger Awards are the first true, impartial measure of the reach, resonance and relevance of an influencer channel.”The third edition of the African Blogger Awards will be held in February 2016.SAinfo reporterlast_img read more

No plan yet for NRC non-applicants

first_imgWhat will Assam do with the 3.9 lakh people who had opted out or not applied for inclusion in the National Register of Citizens (NRC)?They don’t seem to be in the current scheme of things, at least while the exercise is on to publish the final list of citizens by August 31, a date fixed by the Supreme Court.The draft NRC published on July 30, 2018, had excluded 4,007,707 people out of a total of 32,991,284 applicants. Another 102,462 were filtered out of those who made it to the draft NRC, and put in a list of rejected persons on June 26.Officials handling the NRC exercise said 3,612,019 out of the 40.07 lakh in the first exclusion list had reapplied. There is no data on how many of the rejected persons in the second list have reapplied. The State government indicated a plan would be worked out for the non-applicants once the NRC dust settles. “The State Coordinator for NRC is yet to share the details [about those who did not apply],” said Ashutosh Agnihotri, Assam’s Home Commissioner and Secretary. Studies have revealed that majority of poor tribal people do not possess or have not preserved legacy data — sets of documents that include the 1951 NRC and electoral rolls up to the midnight of March 24, 1971 — to prove their citizenship, despite being descendants of the indigenous peoples of Assam.last_img read more
