first_imgMessages of congratulations were read out from MP Jay Hill, MLA Blair Lekstrom, and from the McNaught Homestead Preservation Society and Beaverlodge and Area Cultural Society. To complete the festivities, Mark Wilfur of Talisman Energy was on hand to present a much appreciated cheque to the Museum Foundation for its ongoing palaeontology projects, the development of the new Dinosaur Discovery Gallery, and its educational programs. An enthusiastic crowd of 150 gathered for the long-anticipated opening of new museum exhibits in the Tumbler Ridge Community Centre on Thursday November 26th at noon. The exhibits, developed by the Tumbler Ridge Museum Foundation, were funded by the Women, Seniors and Elders Project of the BC150 celebrations, in partnership with the BC Museums Association and the District of Tumbler Ridge.One exhibit celebrates the remarkable art of Euphemia “Betty” McNaught, likely the most famous artist the Peace Region has produced. Reproductions of twenty four of her pioneering paintings in British Columbia grace one well-lit wall, along with text paneles and photographs of her from childhood to her later years. Betty McNaught lived to be 100, and her art spanned almost the whole twentieth century; she trained in Ontario where her style was influenced by members of the Group of Seven, and settled in Beaverlodge, where she became an inspiration and living legend.The second celebrates Janet Hartford, the esteemed “Matriarch of Tumbler Ridge”, who has done so much for the community since its inception 27 years ago. In addition to the unveiling of text panels and photographs that detail her remarkable life and volunteerism, a specially commissioned painting of Janet by renowned local artist Joan Zimmer was unveiled by Mayor-Elect Larry White. One of Janet and her husband George’s most cherished contributions to Tumbler Ridge was the creation of the Indoor Playground, so it was most appropriate that this magnificent portrait of Janet directly overlooks this forever busy destination for kids in town.- Advertisement -The joyous ceremony began with a remarkable unveiling by another immensely talented Tumbler Ridge artist, Rita Henderson. “Ancient pathways – The Hunters” (oil on wood) is an 8’ x 4’ mural depicting a First Nations mountain scene in the Tumbler Ridge area from 5000 years ago. This superb work of art completes another Museum Foundation exhibit in the Community Centre, also funded by BC150. Lunch followed, with those present enthralled by the art and exhibits on display, and appreciative of the opportunity to partake in the recognition of such special people. Thanks to the support of BC150, five permanent exhibits have been created in the Tumbler Ridge Community centre, and together these enhancements provide a unique celebration of heritage for residents and visitors alike.Advertisementlast_img read more

first_imgTHE Government has been accused of doing a u-turn over school transport in the Finn Valley.The Finn Valley School Transport Action Group claims promises made in June have already been broken.“At a meeting with a civil  servant in the Transport Section, Dept of Education and Skills on 24th of June, FVSTAG committeee members and TD Dinny McGinley were advised that once Parents wrote to Department advising that Deele College was over capacity that transport for this year would automatically roll over to Stranorlar and so would the Medical Card,” said a FVSTAG spokesman. “However, it has now emerged, that Medical Card Holders are being asked to pay for their concessionary ticket and that their appeals have been turned down.“Fvstag are advising families affected by this to contact the civil servant and her department and query why their appeal was turned down after assurances had been given on June 24th.“We would ask people to please phone immediately on 057 9325471.

New survey suggests far fewer Jupiter sized rogue planets than thought

first_img Explore further Back in 2011, an international team of researchers conducted a study of rogue planets and reported evidence suggesting that there are approximately twice as many rogue Jupiters as main sequence stars. In this new effort, the researchers took a new census gain a more accurate estimate.Identifying rogue planets is difficult, of course, because they do not emit any light of their own—against the black of space, there is nothing to see. But when they move past light emitted from a distant star, a lensing phenomenon can occur. This happens when light from the blocked star is magnified by the planet’s gravity, causing a lensing halo effect that can be seen by instruments here on Earth. The size of the planet can also be calculated by noting the lensing duration. The researchers with this new census winnowed down the millions of stars in the dataset to just 2,617 high-quality microlensing events. This represented a much larger sample size than the one used by the team in 2011—they analyzed just 474 events.The researchers conclude that Jupiter-sized rogue planets are far rarer than the earlier census claimed. But they note it is possible that are more Earth-sized rogue planets roaming around than currently believed. The data also showed that of the big rogue planets roaming the Milky Way, approximately 25 percent of them are likely gas giants, with the remaining 75 percent represented by rocky or ice giants.

No large population of unbound or wide-orbit Jupiter-mass planets, Nature (2017). DOI: 10.1038/nature23276Planet formation theories predict that some planets may be ejected from their parent systems as result of dynamical interactions and other processes. Unbound planets can also be formed through gravitational collapse, in a way similar to that in which stars form. A handful of free-floating planetary-mass objects have been discovered by infrared surveys of young stellar clusters and star-forming regions as well as wide-field surveys, but these studies are incomplete for objects below five Jupiter masses. Gravitational microlensing is the only method capable of exploring the entire population of free-floating planets down to Mars-mass objects, because the microlensing signal does not depend on the brightness of the lensing object. A characteristic timescale of microlensing events depends on the mass of the lens: the less massive the lens, the shorter the microlensing event. A previous analysis of 474 microlensing events found an excess of ten very short events (1–2 days)—more than known stellar populations would suggest—indicating the existence of a large population of unbound or wide-orbit Jupiter-mass planets (reported to be almost twice as common as main-sequence stars). These results, however, do not match predictions of planet-formation theories and surveys of young clusters. Here we analyse a sample of microlensing events six times larger than that of ref. 11 discovered during the years 2010–15. Although our survey has very high sensitivity (detection efficiency) to short-timescale (1–2 days) microlensing events, we found no excess of events with timescales in this range, with a 95 per cent upper limit on the frequency of Jupiter-mass free-floating or wide-orbit planets of 0.25 planets per main-sequence star. We detected a few possible ultrashort-timescale events (with timescales of less than half a day), which may indicate the existence of Earth-mass and super-Earth-mass free-floating planets, as predicted by planet-formation theories. Journal information: Nature (Phys.org)—A team of researchers with Warsaw University Observatory, Ohio State University and the University of Warwick has found evidence that suggests there are far fewer Jupiter-sized rogue planets roaming the Milky Way galaxy than prior surveys have shown. In their paper published in the journal Nature, the group describes using data compiled from the Optical Gravitational Lensing Experiment to analyze light curves of approximately 50 million stars for the period 2010 to 2015 and what they found by doing so. The gravity of a free-floating planet may deflect and focus light from a distant source star when passing closely in front of it. Owing to the distorted image the star temporarily seems much brighter. Credit: J. Skowron / Warsaw University Observatory The researchers conclude by suggesting their findings jibe with logic—there are likely to be fewer rogue giant planets because they would have a stronger gravitational connection to their original star system. Smaller, Earth-like planets, on the other hand, could be flung off with relative ease. This document is subject to copyright.

Dwarkanath Tagores bust unveiled in London

first_imgLondon/Kolkata: Prince Dwarkanath Tagore, best known for his significant role in the Bengal Renaissance of the 19th century, has been honoured with a new bust in London. The grandfather of Nobel laureate Rabindranath Tagore was among the first Indian industrialists, also known as merchant princes, investing in a range of businesses from steam engines to banking in the 1820s. He died during a visit to the UK in August 1846 and was buried at Kensal Green Cemetery in north-west London, where his bust was unveiled on Saturday.

He believed the sky’s the limit and his range of accomplishments spanned from coal, tea, jute, shipping, banking and the list can go on,” said Anirban Mukhopadhyay, President of London Sharad Utsav (LSU), among the groups behind the new statue. After decades amid thousands of other graves, LSU joined hands with the Bengal Heritage Foundation and with the support of the British Council, iLead (Kolkata), Friends of Kensal Green (London) launched the bust and a plaque marking Dwarkanath’s contributions.

Kolkata-based businessman Pradeep Chopra travelled all the way from India with his family for the occasion. Dwarkanath died aged 52 at St. George’s Hotel in London during a major thunderstorm in the city. Britain’s then Queen, Victoria, and husband Prince Albert, who had welcomed him to their court like “an old friend” earlier, sent four carriages to the funeral for a so-called “princely” send-off.last_img read more
