January Podcast: Jupiter and Orion

    From:- Sky & Telescope    By :- J. Kelly Beatty   Editted by :- Amal Udawatta Dazzling Jupiter and the brilliant stars of Orion, the Hunter — as well as Sirius and Procyon — dominate the eastern sky during January evenings. We’ll want to make good on that pledge right away, because our first opportunity occurs early in January, with the arrival of the Quadrantid meteor shower. These meteors get their name from Quadrans Muralis, an obsolete constellation near the handle of the Big Dipper. Unfortunately this year the peak arrives in the Americas on the afternoon of January 3rd — and there’s a full Moon that night. Bummer! Of the five planets visible by eye, three of them — Mercury, Venus, and Mars — are bunched closely together very close to the Sun in the sky and thus out of view this whole month. That leaves Jupiter and Saturn to entertain us. Right now Saturn is fairly high in the southwest after even twilight fades. Meanwhile, Jupiter reaches what’s ca...

Saving South Africa's threatened albatross from lethal fishing lines

   From :- BBC World News    By :-   Mayeni Jones ( Africa Correspondent, Cape Town)    Editted by :- Amal Udawatta    Cape Town Pelagics Albatrosses are particularly vulnerable to being harmed by fishing boats On a small boat in the Atlantic, about 27 nautical miles (50km) away from South Africa's Cape Point, a group of bird watchers are calling out seabird names: "Atlantic yellow-nosed! Black-browed albatross!" The tour boat takes bird watchers from Cape Town to see endangered seabirds, including albatrosses, that are hard to find on the mainland. It's a warm summer's day and the sky is blue and clear, perfect conditions for bird-watching. The skipper is speaking on his radio - he's looking for fishing trawlers. He soon finds one, and makes a beeline towards it. The closer the boat - operated by Cape Town Pelagics, a non-profit organisation - gets to the fishing vessels, the more seabirds appear. As he stops right next to the fishing b...

Did Astronomers See a Star Explode Twice?

     From :- W.M. KECK Observatory       By :-  :   Meagan O’Shea      Editted by :- Amal Udawatta Artist interpretation depicts a hypothesized event known as a superkilonova. Initially, a massive star explodes in a supernova, which generates elements like carbon and iron (left). In the aftermath, two neutron stars are born, at least one of which is believed to be less massive than our Sun (middle). The neutron stars spiral together, sending gravitational waves rippling through the cosmos, before merging in a dramatic kilonova (right). Kilonovae seed the universe with the heaviest elements, such as gold at platinum, which glow in red light as depicted in the animation. Credit: Caltech/K. Miller and R. Hurt (IPAC)  A team of astronomers using a variety of telescopes, including the W. M. Keck Observatory on Maunakea, HawaiĘ»i Island, have discovered a possible “Superkilonova” that exploded not once but twice, evidence that this o...

What are professional footballers tucking into at Christmas?

   From :- BBC News    By :- Srosh Khan and Naomi de Souza Edited by :- Amal Udawatta    Handout Tommy Cole works with nutritionists at football clubs to make sure players get the most out of their meals Many of us have been waiting all year to tuck into our favourite festive treats. Christmas dinner can look very different for each household - but for professional footballers, it is still a time to stay focused on fitness and recovery for matches. Private chef Tommy Cole whips up meals for Premier League players from major clubs - including Fulham, Chelsea and Brighton - all year round. When it comes to the main Christmas meal, he takes a traditional approach, but makes it "a little boujee-r" and healthier. "With roast potatoes, for example, it's just being careful not to roast them in a crazy amount of fat, whilst still trying to make them nice and crispy," he tells BBC Newsbeat. "Also things like your fillings, again, just being careful with the amount o...
