CFCs are used primarily as a foaming agent for building insulation, refrigerators and other consumer products. In 1985, scientists discovered a hole in the ozone layer that protects the earth's surface from harmful ultraviolet radiation above the Antarctic, which led to the Montreal Protocol of 1987.

They asked them to consider the projected melting of each of the Greenland , West Antarctic and East Antarctic ice sheets under low and high future global temperature rise scenarios. Lead author professor Jonathan Bamber , from the University of Bristol , said: 'Structured expert judgment provides a formal approach for estimating uncertain quantities based on current scientific understanding, and can be useful for estimating quantities that are hard to model.

But you better hurry up, because your boarding pass will earn you "frequent flyer" points, which you can later exchange for goodies. The space agency's Mars 2020 rover is expected to land on the Red Planet in February 2021. One or more chips will sit under a glass cover on the rover. For each "flight", you'll be awarded miles and corresponding digital mission patches that can be downloaded, according to this source .

The system can be programmed to carry out various microgravity experiments as well and it's made out of three robots and a docking station they will eventually learn to go to by themselves if they sense that their batteries are depleting. And the recent test was all about to see how robots can take care of spacecraft when astronauts are away. These robots will come in handy during the space agency's lunar missions and other deep space missions.

Native Americans named the May full moon the "flower" moon because the month marks a time of increased fertility with the warmer temperatures and the plants in bloom. This will be the final season blue moon until August 2021, according to CNN . Where Can I Catch the Best Views of the Blue Flower Moon? Every full moon of every months has a specific title.

HBO's long-running juggernaut Game Of Thrones is coming to an end this Sunday, and while the spectacle has been high, so too has the social media "whinging". We also get a glimpse of a furious Arya standing among the victorious, cheering Dothraki, before the new Queen of the Ashes emerges to claim the smoking heap of the once great city as her own.

Musk said SpaceX plans to launch roughly 60 satellites at a time as it builds out its constellation. The payload fairing for the first Starlink Falcon 9 mission. Another six launches will be required before even "minor" coverage is offered. He forecast that high-density deployment of satellites could cause a cascade effect, and where each collision generates space debris that increases the likelihood of further collisions in space.

Following the expedition, the team now plans to conduct a study to find out if the sea creatures they had collected contain microplastics or not. "Most importantly we have opened the door to the final frontier-the exploration of the hadal zone and the workings of the deepest parts of the world's oceans", said Rob McCallum of EYOS Expeditions, whose company is managing the expedition.

Vescovo's team discovered four potentially new species of prawn-like crustaceans called amphipods, a spoon worm at 7,000 meters and a pink snailfish at 8,000 meters. After Vescovo's record-breaking dive , other team members took four other subsequent dives to the trench. He found sea creatures, but also found a plastic bag and sweet wrappers .

He spent four hours exploring the bottom of the trench in his sub, built to withstand the vast pressure of the deep ocean. Down there he found incredible sea creatures, but also found a plastic bag and sweet wrappers . Plastic waste has reached epidemic proportions in the world's oceans with an estimated 100 million tonnes dumped there to date, according to the United Nations.

The moon is shrinking - much like the way a grape shrivels into a raisin - and that may be causing it to have "moonquakes," according to NASA . Scientists know the Moon is too cold and still to have plate tectonics, like Earth, which keeps our whole crust sliding around in giant, continent-sized pieces.

That journey was made by filmmaker James Cameron in 2012. Over four hours exploring the seabed of the trench he saw sea creatures, plastic bags and lolly wrappers. This is a widespread problem for sea creatures, even those living extremely deep in the ocean, a recent study has found. From behind the glass of a submersible created to withstand extreme pressures, he spent hours observing and documenting the quiet, dark alien world.

The barges, each carrying 25,000 barrels of a gasoline-refining product called reformate, were traveling the inbound lane. The U.S. Coast Guard has set up an incident command and reported no injuries Friday night. It's trying to determine how much reformate leaked into the channel. The liquid leaked into the bay is highly-flammable, toxic to marine life and could be deadly to anyone who ingests it.

But not all. We might be able to throw our polyethylene terephthalate (PET) drink bottles into the recycling bin, but not a tough, thermoset plastic toy or utensil. The structure of most plastics is comprised of large molecules called polymers which are themselves made up of smaller carbon containing monomers. Plastic pollution in the world's oceans may have a $A3.6 trillion impact, negatively affecting "almost all marine ecosystem services", including areas such as fisheries, recreation and ...

He added that Blue Origin can help NASA meet its new timeline with its Blue Moon lander "only because we started this three years ago". Trump in 2017 made a return to the moon a high priority for the USA space program, saying a mission to put astronauts back on the lunar surface would establish a foundation for an eventual journey to put humans on Mars.

Air Force. Israel seeks to become the fourth country in the world, after Russian Federation, the United States and China, to land a spacecraft on the moon. Beresheet will also deposit a " time capsule " of digital files the size of coins which contain the Bible, children's drawings, Israel's national anthem and flag, as well as memories of a Holocaust survivor and Israeli songs and prayers.

Making its second visit to the space station, the reusable Dragon capsule's pressurized cabin was packed with crew food, clothing and personal items, spare parts, computer gear and 1,600 pounds of science equipment and research material. "Way to make it look easy". It was the first time a launch like this was nixed by rocket-landing concerns. After four weeks at the ISS, the Dragon, with a cargo of 4,400 pounds, will leave the space station and begin its return to Earth, splashing down in ...

Pompeo emphasized that China isn't an Arctic state and that its observer status is contingent upon its respect for the sovereignty of the permanent member nations. "Just because the Arctic is a place of wilderness does not mean it should become a place of lawlessness", he said. Many of those critics fear the administration is intent on using Arctic resources with no thought for its consequences or mitigation.

Astronomers have put together the largest and most comprehensive "history book" of galaxies into one single image, using 16 years' worth of observations from NASA's Hubble Space Telescope . The new portrait, a mosaic of multiple snapshots, covers nearly the width of the full Moon, and chronicles the universe's evolutionary history in one sweeping view.
