WASHINGTON — After the Big Bang, it was cold and black. And then there was light. Now, for the first time, astronomers have glimpsed that dawn of the universe 13.6 billion years ago when the earliest stars were turning on the light in the cosmic darkness.
And if that’s not enough, they may have detected mysterious dark matter at work, too.
WASHINGTON — Scientists tag sharks to see where they roam in the high seas, but until now they couldn’t track the seas’ biggest eater: Humans.
By using ships’ own emergency beacons, researchers got the first comprehensive snapshot of industrial fishing’s impacts around the globe. And it’s huge ‚Äî bigger than scientists thought, according to a new study.
WASHINGTON — The fireball that streaked through the Michigan sky put on quite a show but as far as potentially killer space rocks, it was merely a flash in the pan.
There are much bigger asteroids careening through our solar system. Scientists who watch for them hope they spot them in time to get people out of the way if a truly dangerous one is heading straight to Earth.
WASHINGTON — Consider this cold comfort: A quick study of the brutal American cold snap found that the Arctic blast really wasn’t global warming but a freak of nature.
WASHINGTON — Global warming is making the world’s oceans sicker, depleting them of oxygen and harming delicate coral reefs more often, two studies show.
The lower oxygen levels are making marine life far more vulnerable, the researchers said. Oxygen is crucial for nearly all life in the oceans, except for a few microbes.
WASHINGTON — The term bomb cyclone sounds scary, but it’s a real weather term and it fits the storm that sprang up from the U.S. Southeast.
WASHINGTON — Summer thunderstorms in North America will likely be larger, wetter and more frequent in a warmer world, dumping 80 per cent more rain in some areas and worsening flooding, a new study says.
Future storms will also be wilder, soaking entire cities and huge portions of states, according to a federally-funded study released Monday in the journal Nature Climate Change.
WASHINGTON — Scientists say global carbon pollution went up this year after three straight years when it didn’t go up at all.
Preliminary figures project that worldwide carbon dioxide emissions rose about 2 per cent. The heat-trapping gas is a key cause of global warming.
The report out Monday dashes hopes that emissions from the burning of coal, oil and gas had peaked.
WASHINGTON — The ozone hole over Antarctica shrank to its smallest peak since 1988, NASA said Thursday.
The huge hole in Earth’s protective ozone layer reached its maximum this year in September, and this year NASA said it was 7.6 million square miles wide (19.6 million square kilometres). The hole size shrinks after mid-September.
