More than 37 million pieces of plastic debris have accumulated on a remote island in the South Pacific, thousands of miles from the nearest city, according to estimates from researchers who documented the accumulating trash. Turtles get tangled in fishing line, and hermit crabs make their homes in plastic containers. The high-tide line is demarcated by litter. Small scraps of...

Clear skies and a setting sun provided a stunning backdrop as SpaceX launched an expendable Falcon 9 with the last of four Inmarsat-5 Global Xpress (GX) telecommunications satellites. The Falcon 9, in an increasingly-rare expendable configuration, lifted off at 7:21 p.m. EDT (23:20 GMT) from Launch Complex 39A (LC-39A) and deposited the Inmarsat-5 F4 satellite into a geosynchronous transfer orbit (GTO) around...
When NASA launches its new big rocket for the first time — more than a year and a half from now, at the earliest — there will be no astronauts along for the ride. In February, at the request of the Trump administration, NASA began studying whether it was possible to add crew for the first flight of its Space...
Researchers have found 3.5 billion-year-old fossilized microbial deposits in Western Australia, which could provide clues on the emergence of life on Earth — and other planets. Ancient hot spring deposits found in Australia’s desert could help unlock the mystery of how life evolved on Earth, and provide clues for scientists searching for extraterrestrial existence, according to a new study. A team...
A powerhouse communications satellite owned by Inmarsat has been fueled for liftoff on a SpaceX Falcon 9 rocket Monday from the Kennedy Space Center in Florida on a mission to provide broadband links for passengers and crews aboard ships and airplanes, while ground crews are loading space station-bound supplies into a commercial Dragon cargo capsule and preparing a Bulgarian...
In a path breaking motion on Monday, May 1, the U.S. Supreme Court declined to hear a challenge against the U.S. Fish and Wildlife Service. The U.S. federal agency for protection of flora and fauna had requested the Supreme Court to designate a major chunk of Arctic ice shelf (120 million acres) as critical polar bear habitat. The state of Alaska along...
As the Cassini spacecraft swooped between Saturn and its innermost ring on April 26th, one of its instruments listened for the sounds of its passage through the heretofore unexplored region. What it heard was of great interest to engineers planning for the second dive, and as well as to scientists who study Saturn’s rings. The engineers were hoping to hear the...
New climate-change findings mean the Pacific Ocean off California may rise higher, and storms and high tides hit harder, than previously thought, officials said. The state’s Ocean Protection Council on Wednesday revised upward its predictions for how much water off California will rise as the climate warms. The forecast helps agencies in the nation’s most populous state plan for climate...
We often wonder if somewhere hidden on Mars are the building blocks for life. But what about building blocks for a civilization? A new study suggests that the material humanity needs to one day construct houses, buildings and even entire colonies on Mars may already exist within the red planet’s own desolate soil. The research is still early and the...
You may have seen headlines proclaiming that the great mystery of Antarctica's "Blood Falls" has finally been solved. That's a little silly, because the big mystery—the question of why blood-like bright red liquid oozes out of the otherwise white surface of Taylor Glacier—hasn't been all that mysterious for some time. Two years ago, a study suggested that the water,...
