WASHINGTON Cheap Indianapolis Colts Hats , Dec. 7 (Xinhua) -- A sudden outburst of jets from ablack hole 8,000 light years from Earth has offered astronomers arare opportunity to measure the surrounding magnetic field, only tofind it weaker than expected.
The results appear to go against our current understanding ofblack holes that are famous for its intense gravitational pullknown to gobble up entire stars and launch streams of matter intospace at almost the speed of light, according to a study publishedThursday in the U.S. journal Science.
"We weren't expecting this Cheap Indianapolis Colts T-Shirts , so it changes much of what wethought we knew," said study co-author Stephen Eikenberry, aprofessor of astronomy in University of Florida's College ofLiberal Arts and Sciences.
On June 15, 2015 Cheap Indianapolis Colts Hoodie , astronomers detected a sudden flare from abinary system called V404 Cygni, which contains a 40-mile-wide(64-kilometer-wide) black hole.
They quickly mobilized radio, infrared, optical Customized Indianapolis Colts Jersey , and X-raytelescopes to collect data during the two week-long outburst.
It turned out the magnetic energy around the black hole is about400 times lower than previous crude estimates.
"Our surprisingly low measurements will force new constraints ontheoretical models that previously focused on strong magneticfields accelerating and directing the jet flows," saidEikenberry.
So far, astronomers are baffled on how "jets" of particlestraveling at nearly the speed of light shoot out of black holes'magnetic fields, while everything else is sucked into theirabysses Cheap Indianapolis Colts Jerseys , he said.
Outbursts of small black holes, like the one observed for thestudy, occur suddenly and are short-lived, said the study.
The 2015 outbursts of V404 Cygni lasted only a couple of weeks.The previous time the same black hole had a similar episode was in1989.
"To observe it was something that happens once or twice in one'scareer Matt Slauson Colts Jersey ," said study lead author Yigit Dalilar, a doctoral studentin University of Florida's astronomy department. "This discoveryputs us one step closer to understanding how the universe works."

UNITED NATIONS, March 7 (Xinhua) -- The United Nations and its partners in Madagascar are working with the government's office of national disaster and risk management to respond to the immediate humanitarian needs following tropical cyclone Enawo, a UN spokesman said here Tuesday.
Tropical cyclone Enawo is the most powerful storm in 13 years.
""UN agencies have scaled up their presence to support the government in responding to the potentially devastating humanitarian impacts of this natural disaster which struck the island today,"" the deputy UN spokesman, Farhan Haq, said at a daily news briefing here.
About 760,000 people are likely to be directly affected and nine regions are at high risk of either floods or severe impact of winds.
Tropical cyclone Enawo pushed ashore Tuesday morning in northeastern Madagascar with winds equal to a Category 4 hurricane, reports said.
Aid workers were on alert as the storm lashed the coastline, the reports said, adding that there were no immediate reports of damage or casualties.
Enawo is forecast to rapidly weaken as it drives inland over the mountainous terrain of Madagascar, the reports added.
" It is always a challenge to find a proper and useful toy for your child. On the one hand a toy must be useful for the baby?s development, on the other- it must be harmless. To select a correct toy for the baby you know some of his or her peculiarities of thinking and behaviour at stages of his or her development. Let us help you to discover the interesting and beautiful world of baby toys for your child from the ages of 3-6 months old.
In the period of 6-9 month the agility of your baby develops and becomes more complicated. He or she is grabbling freely and even tries to stand up onto two legs. Simultaneously small hand mobility develops: little one tries not just to grip the object in his palm, but also take it with his or her fingers.
Formerly a baby got acquainted with his or her surrounding objects occasionally Ryan Grant Colts Jersey , now their actions are purposeful. Liberalisation of the little person?s horizon will depend on adults. It is a serious thing for you to show your baby how to play with various toys: how to bang a little drum, how to play the small piano and press the keys, how to handle and ring the ball. At this age babies still chew and play with the rattles and tweeters, but they are also interested in more compound toys like little cars and books with bright pictures (note Eric Ebron Colts Jersey , always buy books with thick cardboard for small children!).
This age is a special period of time for the parents. Expression ?being all eyes? more precisely describes the given situation. Some parents try to restrain the moving activity of their children from considerations of safety or not having enough time to look after them. But you must protect your child only against that is really dangerous to them. Children must learn out from their mistakes.
At the 9 months old the child understands that he or she can play with two toys simultaneously. For example, if they beat one toy on another, a sound will appear (tinkling, rattling) and the child likes these kind of sounds. Now they can play with bricks and pyramidions. In the beginning the child will smash and destroy the built houses and castles Jack Mewhort Colts Jersey , but with time he or she will try to build them on their own. There are special meccanos of flexible plastic for 7-9 month old babies. As a rule, these are open-ended rings, which are linked easily together (though children like to nibble them).
By now a child can play simple games with the adults like ?clapping palms?, ?cuckoo? T.Y. Hilton Colts Jersey , and ?let?s fly? etc. Ask your baby to find this or that toy, asking ?Where is the rabbit?? If your child does not understand or finds a difficulty in finding the toy, h.
