Astronomers find dozens of massive, ancient galaxies

Astronomers find dozens of massive, ancient galaxies

Science
Aug. 7 (UPI) -- Astronomers have discovered an abundance of vast, ancient galaxies. Scientists spotted the galaxies in the distant universe using the combined power of several space observatories. The discovery, published Wednesday in the journal Nature, could force cosmologists to change their models of the universe. Most models don't predict such an abundance of massive galaxies so early in the evolution of the universe. "This is the first time that such a large population of massive galaxies was confirmed during the first 2 billion years of the 13.7-billion-year life of the universe. These were previously invisible to us," Tao Wang, researcher at the University of Tokyo, said in a news release. "This finding contravenes current models for that period of cosmic evolution and will help ...

Ice sheets in Patagonia are more massive than scientists thought

Ice sheets in Patagonia are more massive than scientists thought

Science
June 4 (UPI) -- A seven-year survey of Patagonia's ice suggests the slabs of ice that stretch across vast portions of Argentina and Chile are thicker than scientists thought, measuring more than a mile in thickness in some places. "We did not think the ice fields on the Patagonian plateau could be quite that substantial," Eric Rignot, professor of earth sciences at the University of California, Irvine, said in a news release. "As a result of this multinational research project, we found that -- added together -- the northern and southern portions of Patagonia clearly hold more ice than anticipated, roughly 40 times the ice volume of the European Alps." Measurements collected using satellite radar altimetry and optical imagery suggest most of Patagonia's ice sheets have been rapidly thinn...

Business
Uber has lost nearly $ 8bn (£6.1bn) during its 10 years of existence, according to documents released ahead of its debut on the stock market.The ride-hailing firm also disclosed that government authorities and regulators in the US are investigating a year-long cover-up after the details of millions of passengers and drivers were stolen in 2016. Uber chief executive Dara Khosrowshahi said: "Some of the attributes that made Uber a wildly successful startup - a fierce sense of entrepreneurialism, our willingness to take risks that others might not, and that famous Uber hustle - led to missteps along the way."Mr Khosrowshahi, who took over the company 18 months ago, has vowed to run it with integrity.The bankers handling Uber's IPO (initial public offering) are expected to reveal a pricing ran
