Sun .. The Sun Amazing Documentary ..
By Discovery HD CH ..

The Sun is a G-type main-sequence star that comprises about 99.86% of the mass of the Solar System .. Once regarded by astronomers as a small and relatively insignificant star, the Sun has an absolute magnitude of +4.83 .. This is now estimated to be brighter than about 85% of the stars in the Milky Way, most of which are red dwarfs ..

The Sun is composed primarily of the chemical elements hydrogen and helium; they account for 74.9% and 23.8% of the mass of the Sun in the photosphere, respectively .. All heavier elements, called metals in astronomy, account for less than 2% of the mass .. The most abundant metals are oxygen (roughly 1% of the Sun's mass), carbon (0.3%), neon (0.2%), and iron (0.2%) ..

The Sun inherited its chemical composition from the interstellar medium out of which it formed .. The hydrogen and helium in the Sun were produced by Big Bang nucleosynthesis, and the metals were produced by stellar nucleosynthesis in generations of stars that completed their stellar evolution and returned their material to the interstellar medium before the formation of the Sun .. The chemical composition of the photosphere is normally considered representative of the composition of the primordial Solar System .. However, since the Sun formed, some of the helium and heavy elements have gravitationally settled from the photosphere. Therefore, in today's photosphere the helium fraction is reduced and the metallicity is only 84% of that in the protostellar phase (before nuclear fusion in the core started) .. The protostellar Sun's composition was reconstructed as 71.1% hydrogen, 27.4% helium, and 1.5% metals ..

The core of the Sun extends from the center to about 20–25% of the solar radius .. It has a density of up to 150 g/cm3 (about 150 times the density of water) and a temperature of close to 15.7 million kelvin (K) .. By contrast, the Sun's surface temperature is approximately 5,800 K .. Recent analysis of SOHO mission data favors a faster rotation rate in the core than in the rest of the radiative zone .. Through most of the Sun's life, energy is produced by nuclear fusion through a series of steps called the p–p (proton–proton) chain; this process converts hydrogen into helium .. Only 0.8% of the energy generated in the Sun comes from the CNO cycle ..

While having a 81.5 Kilometer height orbit around Kerbin, a strange anomaly was detected, some strange gravity and a purple spot appearing out of nowhere, causing his ship to be sucked in. That anomaly was a wormhole that teleported him and his ship about 46 lightyears to within the atmosphere of a planet orbiting a G-type main-sequence star; Earth. The ship didn't exactly survive the wormhole travel, but HE did. Out of all odds, he survived the fall almost uninjured, but unconscious. He woke up a bit later, looking around, seeing unfamiliar territory

The Sun's color is white, with a CIE color-space index near (0.3, 0.3), when viewed from space or when high in the sky; when low in the sky, atmospheric scattering renders the Sun yellow, red, orange, or magenta. Despite its typical whiteness, most people mentally picture the Sun as yellow; the reasons for this are the subject of debate.[42] The Sun is a G2V star, with G2 indicating its surface temperature of approximately 5,778 K (5,505 °C, 9,941 °F), and V that it, like most stars, is a main-sequence star.[43][44] The luminance of the Sun is about 1.88 gigacandela per square metre, but as viewed through Earth's atmosphere, this is lowered to about 1.44 Gcd/m2.[45]

The Sun is a G-type main-sequence star that comprises about 99.86% of the mass of the Solar System. Once regarded by astronomers as a small and relatively insignificant star, the Sun has an absolute magnitude of +4.83. This is now estimated to be brighter than about 85% of the stars in the Milky Way, most of which are red dwarfs.[25][26] The Sun is a Population I, or heavy-element-rich,[c] star.[27] The formation of the Sun may have been triggered by shockwaves from one or more nearby supernovae.[28] This is suggested by a high abundance of heavy elements in the Solar System, such as gold and uranium, relative to the abundances of these elements in so-called Population II, heavy-element-poor, stars. These elements could most plausibly have been produced by endothermic nuclear reactions during a supernova, or by transmutation through neutron absorption within a massive second-generation star.[27]

The Sun is a G-type main-sequence star (G2V) based on spectral class and it is informally designated as a yellow dwarf. It formed approximately 4.567 billion[b][17] years ago from the gravitational collapse of a region within a large molecular cloud. Most of the matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System. The central mass became increasingly hot and dense, eventually initiating thermonuclear fusion in its core. It is thought that almost all stars form by this process. The Sun is roughly middle age and has not changed dramatically for four billion[b] years, and will remain fairly stable for four billion more. However, after hydrogen fusion in its core has stopped, the Sun will undergo severe changes and become a red giant. It is calculated that the Sun will become sufficiently large to engulf the current orbits of Mercury, Venus, and possibly Earth.

https://plus.google.com/118287182731909579925 Woodbine Entertainment Group : Snowbirds: Report on Woodbine trainers for the period February 17 – February 23: TORONTO, February 24...
Snowbirds: Report on Woodbine trainers for the period February 17 – February 23: TORONTO, February 24 - Welcome to the eighth edition of our weekly Snowbirds report chronicling the winter adventures of Woodbine-based trainers currently plying their trade south of the border.   For those wanting a closer look at the frosty fun on the Woodbine backstretch, click the 'WATCH VIDEO' button on the right-hand side of the page for interviews with lead pony rider Misty Husdon and assistant trainer Josie DePaulo.   Although the Woodbine backstretch opened on Friday, the vast majority of our training contingent are still taking care of business in the warmer climate of Gulfstream Park, Oaklawn Park and Santa Anita.  It was an incredible week for our hard working trainers with six conditioners making their way to the winner’s circle last week including Roger Attfield, Julia Carey, Mark Casse, Ricky Griffith, Brian Lynch and Lorne Richards.   And while jockey Jesse Campbell may be spending his winter in Ontario, rest assured the journeyman rider is working just as hard, if not harder, than his Snowbird colleagues.   Campbell enjoyed a tremendous 2014 campaign at Woodbine winning 100 races including eight stakes scores. However, his season came to a thudding halt on the penultimate day of the meet when Sweet Corinna bucked at the start sending the rider knee first into the gate.   "I've been riding horses a long time and I've never had a horse move like that. Usually, before a horse rears up when the gate opens, they're a little frozen or locked up inside the gate," explained Campbell. "But she was relaxed, she wasn't tense. She just reacted and went up and when she came down, she started to buck and tossed me up in the air.    "She slammed my knee against the gate and that's what really hurt,” he continued. “She couldn't have caught me any cleaner. I've never had a horse do that to me. It goes to show you, if you stick around racing long enough you'll see something you haven't seen before."   Adding insult to injury, Campbell had to watch from hospital as Eurico Rosa da Silva picked up the mount on promising juvenile Kingsport and promptly won the Kingarvie Stakes.   Campbell is hoping that there may be something of a silver lining to the season-ending injury.   "To be honest, I'd been having a bit of a knee problem for months and I was just dealing with it. That incident at the gate was just the last straw," said Campbell of the injury to his left knee.   Fortunately, doctors determined over the offseason that there was no tear suffered in Campbell's knee and promptly prescribed a rehab plan to bring the jock back into racing shape.   "I've been going to rehab for my knee five days a week, two hour sessions, for the past several weeks," said Campbell. "They're throwing the book at me and pushing me hard. They want me to keep at it right through the season and keep getting stronger."   Campbell and Queen's Plate hero Midnight Aria (Burns Photo)   Campbell has earned a reputation as one of the hardest-working riders at Woodbine and his fitness routine was well documented in The Queen's Plate web-series, Path to the Plate. Now, under a strict workout regimen, Campbell is likely to be in midseason shape by April 11, opening day of the 2015 Woodbine meet.   "I feel so much stronger," he said. "I notice a difference with little things like playing with my daughter Madison. I'll get down on the floor with her to play and when I go to get back up I don't have that pain. At Christmas time, I’d get down on the floor and not be able to get back up again."   Already heralded for his ability to finish a race, it's hard to imagine what a stronger Campbell might accomplish in 2015.   "I feel better and more comfortable. This is going to help my game," said Campbell. "There were times last season where I wasn't as comfortable in the saddle and I would change my stirrups and my webbings trying to get comfortable. This is only going to help."   Campbell's 2014 meet started with a flurry of victories including a win in the Woodstock Stakes with Puntrooskie for trainer Nick Gonzalez and owners Tucci Stables.   "We started out white hot and then in the summer I just couldn't win a race," recalled Campbell. “We went through a serious drought before I warmed up again and then we were on fire the last six weeks. That's horse racing. I'm fortunate to have some good clients behind me."   Good clients like Gonzalez and the Tucci Stables, as well as trainer John LeBlanc, Jr. will once again be prominent in 2015.    Last year, Campbell guided LeBlanc's up-and-coming filly Green Doctor to victory in a pair of races including the six furlong Fanfreluche Stakes. The talented miss will be pointed at the $500,000 Woodbine Oaks, presented by Budweiser.   "She has a tremendous mind and a ton of heart. She's a really smart filly," said Campbell. "You work her in the morning and she goes fine, but in the afternoon she's a completely different horse in all the right ways. I don't think she'll have a problem stretching out."   Campbell, who won the 2013 Queen's Plate aboard Midnight Aria, is also anxious to get back aboard the Tucci Stables star and his stablemate River Seven.   "Midnight Aria will always have a special place in my heart. And River Seven, he's a piece of iron," said Campbell.   River Seven finished a bang-up fourth in the Grade 1 Ricoh Woodbine Mile under Campbell's urging and came back to win the Labeeb Stakes in a driving finish over Excaper.   "Man, River Seven is fun to ride," said Campbell. "I got off that horse after the Mile and told Nick that was by far the best race this horse had run in his life. At the turn, I thought we could win that race.   "I thought he might bounce off that race (the Mile) he ran so hard,” he continued. “It really meant a lot to me that River Seven came right back and won the Labeeb. He deserved it. It's hard on good horses to run that hard and not win. They know. That horse would run down a gravel road if you asked him."   And soon Campbell will be back to riding hard at Woodbine as he chases his second Queen’s Plate and a first rider’s title.   "I'm ready to get back at it," said Campbell. "I can't wait for the season to start."   *   And now, let's take a closer look at wins by Woodbine-based trainer last week.   Hall of Fame trainer Roger Attfield picked up his second win of 2015 with a bumping and grinding stretch run from Queen’s Plate hopeful Danish Dynaformer on Feb. 21 at Gulfstream. Sent to post at odds of 11-1 in a 1 1/8-miles grassy maiden allowance, Danish Dynaformer settled near the back of the pack through splits of :24.41 and :48.50 under Luis Contreras.   Contreras rallied wide through the final turn with Danish Dynaformer to take command of the lead and then held off the favoured Dreaming of Gold through a bumping stretch run to secure a narrow neck win. The stewards reviewed the stretch run and after a nervous few minutes of deliberation, the result stood.   Danish Dynaformer, a Charles Fipke homebred son of Dynaformer, was making just his third career start.   Attfield also sent out last year’s Flaming Page stakes winner Meri Shika for an eighth-place effort in the Grade 3 The Very One Stakes at Gulfstream which was won by popular Ontario-bred Irish Mission.   * Julia Carey picked up her first win of the season when Pentathlon wired a 1 1/16-miles turf tilt by 2 ½-lengths at Gulfstream Park on Sunday.  Sent to post at odds of 11-1, Pentathlon was well rated throughout by Gabriel Saez with the victory never in doubt.   Owned and bred by Larry Opas and Frank Sinatra, the victory marked the third career score for the Kentucky-bred daughter of Rockport Harbor.   * Mark Casse sent out ten horses last week and picked up a win with his final roll of the dice when Commute rallied four-wide to win a 6 ½-furlong maiden allowance at Santa Anita on Sunday.   The three-year-old Hold Me Back colt, bred in Kentucky by Meritage LLC and owned by Gabe Grossberg, covered 6 ½-furlongs in a swift 1:15.35.   Casse also sent out: Conquest Curlinate (3rd on Feb. 19 at OP), Noble Bird (6th on Feb. 20 at OP), Sweet Corinna (11th on Feb. 20 at OP), Golden Point (4th on Feb. 20 at TBD), Oakton (7th on Feb. 20 at OP), Conquest Cobra (4th on Feb. 21 at OP), Conquest Harlanday (6th on Feb. 21 at SA), Bollente (7th on Feb. 22 at GP), Hurricane Elvis (6th on Feb. 22 at GP) and Kantune (10th on Feb. 22 at OP.)   * Ricky Griffith picked up a win with his lone starter when Doc John administered a 5 ½-length score in a maiden claiming event on Feb. 20 at Gulfstream. The three-year-old Bellamy Road filly, a Kentucky-bred owned by Debmar Stables, covered the mile in 1:43.22.   * Brian Lynch notched his first win of 2015 on Sunday when Hoarder, an Amerman Racing homebred son of Super Saver, romped a maiden allowance sprint over the Gulfstream main by six lengths.   Sent to post at odds of 11-1, the Kentucky-bred colt tracked the early speed of Abran Paso before taking command a furlong out and was never threatened by the belated rally of the favoured Valiant Knight.  Hoarder, expertly ridden by Rafael Hernandez, covered six furlongs in 1:13.86.   Lynch also sent out Hold the Gold for a fourth-place effort in a 1 1/16-miles turf allowance later on the Saturday card.   * Lorne Richards won with his lone starter last week as Perfect Tay got up in time to win a 1 1/16-miles turf claimer on Sunday at Gulfstream.  It was the fourth career win for the six-year-old Perfect Soul chestnut who was claimed by Richards for $75,000 from Roger Attfield and owner-breeder Charles Fipke out of his second-place debut back on February 18, 2012.   * And now, the rest of the results of our soaring Snowbirds in alphabetical order.   Sid Attard sent out Money Talker for a good fourth-place run at Gulfstream, defeated just 2 ¾-lengths, in Saturday’s Grade 2 Mac Diarmida Stakes won by the brilliant turf star Main Sequence.   Ian Black’s lone starter, Excaper, picked up a cheque with a fifth-place run in Saturday’s Grade 3 Canadian Turf Stakes won by Long on Value.   Josie Carroll sent out Downey Gap for a fourth-place effort on Saturday at Gulfstream.   Mike DePaulo’s Mike the Hab finished a strong second in a Gulfstream Park claiming sprint on Feb. 20 while doubling up off the claim.   Lucky Boots, despite a somewhat unlucky stretch run, closed with authority to finish second in a maiden claiming event on Sunday at Gulfstream for conditioner Michael John Doyle.  The veteran trainer also sent out Samuel Dechamplain for a 10th-place run on Sunday at the Hallandale oval.   Scott Fairlie’s lone starter, Gianni Drama, finished third on Feb. 18 at Penn National.   Nick Gonzalez sent out Woodstock Stakes champ Puntrooskie for a good fourth-place effort in Saturday’s Grade 3 Gulfstream Park Sprint Stakes which was won by C. Zee. Shane Learn’s Northern Hammer nailed down the bottom of the superfecta on Feb. 21 at Parx.   John Mattine saddled Titotime for an eighth-place run on Saturday at Gulfstream.   Saveaplaceforme placed third on Feb. 19 at Gulfstream Park as Alexander Patykewich’s lone starter.   John Simms saddled a pair of starters at Tampa Bay Downs including Fabulous Bear (3rd, Feb. 1) and Clever King (9th, Feb. 22.)   Dan Vella’s lone starter, Trini Boss, finished ninth on Feb. 20 at Gulfstream Park.   Last, but certainly not least, Mike Wright completes this report with a fifth-place run from Malibu Tide on Feb. 20 at Tampa Bay Downs. http://weg.bz/1DmLjdt

Our best view of a stellar debris disk warped by a massive exoplanet

Astronomers working with the Hubble Space Telescope have released the most detailed picture ever taken of a circumstellar debris disk viewed edge-on. It's the only picture we have of a protoplanetary disk with an actual planet orbiting within it.

Beta Pictoris is a 20-million-year old system located about 63 light-years from Earth. This star is in the main sequence stage of its evolution, surrounded by a disk of gas and dust that's slowly congealing into planets.

It also hosts a planet, called Beta Pictoris b, that features a mass between four and 11 Jupiter masses. Because the orbital period is so short — somewhere between 18 and 22 years — astronomers can track large changes in just a few years. Astronomers can thus study how the disk is being distorted by the planet, which is embedded within the protoplanetary disk.

When comparing the image taken back in 1997, it's clear that little has changed in the disk dust distribution. This is surprising given that the entire structure is orbiting the star like a carousel. This suggests the disk's structure is smooth and continuous in the direction on the timescale of the planet's orbital period.

By the way, that black blotch in the center is what's called a coronagraph, which removes the glare of the central star so that the disk can be seen.
