WASHINGTON Mens Jordans 6 Gatorade Sizes 12 , Nov. 26 (Xinhua) — An international team of scientists said Thursday they have for the first time caught a black hole swallowing a star and shooting out a high-speed flare of matter at the center of a nearby galaxy.
The finding, reported in the U.S. journal Science, tracked this unlucky star — about the size of the Sun — as it shifted from its customary path, slipped into the gravitational pull of a supermassive black hole and was sucked in, said lead author Sjoert van Velzen of the Johns Hopkins University.
Though extremely rare, supermassive black holes have been spotted previously eating a star alive. Scientists have also seen flares, or jets Mens Jordans 6 Gatorade Cheap , from supermassive black holes.
“But this is the first time we first get a clear view of the stellar destruction, followed by the jet,” van Velzen said in an email to Xinhua. “The jet is also of much lower power than what we have seen before, which is present an interesting puzzle.”
Van Velzen led the analysis and coordinated the efforts of 13 other scientists in the United States, the Netherlands, Britain and Australia. The team compared the energy produced by the jet in this event to the entire energy output of the Sun over 10 million years.
They concluded that it was likely all supermassive black holes swallowing stars launched jets but this discovery was made possible because the black hole is relatively close to the Earth and was studied soon after it was first seen.
The black hole is only 300 million light-years away from the Earth and the team was able to make their first observations using radio telescopes only three weeks after it was found, they said.
“Previous efforts to find evidence for these jets Mens Jordans 6 Gatorade For Sale , including my own, were late to the game,” said van Velzen.
“Our new findings suggest that this new type of jet could indeed be common,” he said. “Finding more of these rare events may further our understanding of the processes that allow black holes to launch such spectacular outflows.”
WELLINGTON, Aug. 14 (Xinhua) — New Zealand’s population grew by 100,400 in the year ended June 2017, the largest ever increase for a year Mens Jordans 6 Gatorade Shoes , the country’s statistics department Stats NZ said on Monday.
New Zealand’s estimated resident population was 4.79 million as of June 30, and net migration — arrivals minus departures — contributed 72,300 people to the growth, along with 28,100 from natural increase — births minus deaths, said a Stats NZ release.
Half of last year’s growth was in the 15-39 age group, population statistics senior manager Peter Dolan said Mens Jordans 6 Gatorade , adding that this reflects the contribution of migration to the population growth.
Over the last five years, New Zealand’s population grew by nearly 390,000, the release said.
New Zealand’s current gain from net migration equates to 15 people per 1,000 population, and much higher net migration rates were experienced in the late 1870s, it said http://www.airjordan6sgatorade.com , adding that “similar rates to today were also experienced in the early 1900s and early 2000s.”
New Zealand’s current net migration rate is high by New Zealand standards, but historically it has fluctuated more than other countries, Dolan said.
“At the moment, we’re experiencing rates similar to Australia’s in 2009,” Dolan said.
Most migrants are arriving on short-term work and student visas, he said, adding that many of them Cheap Air Jordans 6 Gatorade , however, extend their visas, or transition to other visa types including residence visas, and it makes sense to count long-term stayers as part of the population, rather than as short-term visitors.
As a result of recent migration flows, the share of New Zealand’s population aged 15-39 years rose from 33 percent in 2013 to 34 percent in 2017. This is a reversal of the trend that saw the share drop from 41 percent in the mid-1980s.
Growth of the broad over 65 age group continues to accelerate, up 25 Air Jordans 6 Retro Gatorade ,000 in the last year, as the large birth cohorts of the 1950s-early 1970s begin to reach those ages, the release said.
The population at the oldest ages is also growing, reflecting decreasing death rates at all ages over a long period of time. The over-90 years population is now 30,000 compared with 20,000 in 2007. It is projected to reach 40,000 in the late 2020s and 50 Air Jordans 6 Gatorade Pre Order ,000 in the early 2030s, it said.

BEIJING, Aug. 25 (Xinhua) — The Ministry of Commerce (MOC) said Friday that it has launched an emergency response to ensure the supply of agricultural products to Macao Special Administrative Region (SAR) after this year’s strongest typhoon swept across the region.
The MOC is closely following the progress of the mainland supply of agricultural products to Macao after Typhoon Hato, which killed nine people and injured more than 200 others in the SAR Wednesday, it said in a statement.
The supply of fresh and live agricultural products from the mainland returned to normal on Thursday, MOC said.
The ministry will maintain contact with the local government to ensure sufficient and high-quality supplies continue.
The mainland meteorological authority Wednesday issued this year’s first red alert Air Jordans 6 Gatorade For Sale , the highest in a four-tier warning system, for Typhoon Hato.
