|OTTAWA Angels Josh Hamilton Jersey , April 14 (Xinhua) -- A composite image of a dark matter web, which is believed to connect galaxies, was captured for the first time by Canadian researchers.
The false color image, published in Monthly Notices of the Royal Astronomical Society on Wednesday, shows two galaxies, in white Angels Jered Weaver Jersey , connected by a bridge of dark matter in the red region. The two galaxies are about 40 light years apart.
"For decades, researchers have been predicting the existence of dark-matter filaments between galaxies that act like a web-like superstructure connecting galaxies together," said Mike Hudson, professor of astronomy at the University of Waterloo, in a statement on the university website.
"This image moves us beyond predictions to something we can see and measure," he said in the statement.
Dark matter Angels Huston Street Jersey , which makes up an estimated 25 percent of the universe, can not be directly observed because it does not shine, reflect or interact with light, but its existence and properties are inferred from its gravitational effects such as the motions of visible matter.
By using weak gravitational lensing, Hudson and his co-author Seth Epps measured the effect that dark matter has on light and created a composite image showing the presence of the mysterious substance.
The technique not only enables us to see the existence of dark-matter filaments in the universe, but to observe the extent to which these filaments connect galaxies Angels Garrett Richards Jersey , Epps said.

Defending champions Novak Djokovic and Serena Williams raced into the Australian Open second round on Monday as the year's first Grand Slam was rocked by claims of widespread match-fixing in tennis.
Former winners Roger -Federer and Maria Sharapova also progressed smoothly on a day of high temperatures at Melbourne Park, where one ball boy felt faint and had to be helped from the court.
Djokovic's main opponent was the 35 C heat as, cooling himself with ice vests on the changeovers, the top seed dispatched Korean rising star Chung Hyeon 6-3, 6-2, 6-4.
"You try to stay composed Angels David Freese Jersey , not get carried away by heat, get distracted," said the Serb, who was forced out of the 2009 quarterfinals as he struggled with the heat.
Williams also made a positive return to competitive tennis, four months after a heartbreaking defeat in the US Open semifinals ended her bid for a rare calendar-year Grand Slam.
Showing no discomfort from the swollen knee which forced her out of this month's Hopman Cup mixed-team tournament, Williams toughed it out 6-4 Angels Darin Erstad Jersey , 7-5 against Italy's -Camila Giorgi.
Williams, 34, is seeking an Open-era record-equaling 22nd Grand Slam title, while Djokovic can become only the second man to win six Australian Open crowns after Roy Emerson.
Federer was also untroubled in his 6-2, 6-1, 6-2 win over Georgia's Nicoloz Basilashvili as he continued his quest for a record-extending 18th Grand Slam title.
Sharapova Angels Cliff Pennington Jersey , the women's winner in 2008, beat Japan's Nao Hibino 6-1, 6-3 in just 73 minutes in her first match of the year.
Kei Nishikori, Tomas Berdych and Australia's Nick Kyrgios also went through without significant problems, while Caroline Wozniacki was the biggest casualty on day one.
The former world No.1, who joined fellow seeds Sloane Stephens Angels Cameron Maybin Jersey , Sara Errani and Ivo Karlovic on the sidelines, was stunned in three sets by -Kazakhstan's Yulia Putintseva.
American Stephens, seeded 24th and a former semifinalist, was stunned by Chinese qualifier Wang Qiang 6-3, 6-3.
Canada's Eugenie Bouchard safely reached the second round, and Spain's Carla -Suarez Navarro earned applause when she helped a ball boy from the court as he swooned in high temperatures.
The day was overshadowed by a report which said top-50 players Angels Bud Norris Jersey , including Grand Slam champions, had repeatedly been suspected of match-fixing without facing action.
Three suspect matches were at Wimbledon, and eight of the players under suspicion were due to take to the courts for the Australian Open, the BBC and BuzzFeed claimed.
Association of Tennis Professionals (ATP) chief Chris Kermode rejected any suggestion that match-fixing evidence had been covered up or ignored.
"The Tennis Integrity Unit and the tennis authorities absolutely reject any suggestion that evidence of match-fixing has been suppressed for any reason or isn't being thoroughly investigated," Kermode told -reporters.
