Comments Off on Scientists just found thousands of black holes at the center of our galaxy

For the first time ever, scientists have identified thousands of black holes lurking at the center of our galaxy. Scientists have long suspected that black holes might exist in the middle of the Milky Way, but until now, they haven’t been able to find any evidence. Now, thanks to new research, scientists believe that there are over 10,000 of them swirling together out there. According to a study published in the journal Nature this week, the center of the Milky Way holds 10,000 small black holes that have been previously undetected. Some of these smaller black holes interact with the supermassive black hole known as Sagittarius A* at the core of the galaxy, and give us a peek into how our galaxy formed. Related: Scientists glimpse most distant supermassive black hole in the known universe Using the Chandra X-ray Observatory space telescope, scientists began hunting around for the signature low-level radiation that mark binaries of stars and black holes locked together in space. “When black holes mate with a low mass star, the marriage emits X-ray bursts that are weaker, but consistent and detectable. If we could find black holes that are coupled with low mass stars and we know what fraction of black holes will mate with low mass stars, we could scientifically infer the population of isolated black holes out there,” lead author Chuck Hailey said. By using this method, they located dozens of binaries near Saggitarius A* and, from there, determined that there were thousands more out there. Not only can this information help us understand how the Milky Way originated, but it could help us understand other galaxies as well. Via Mashable Images via Deposit Photos ( 1 , 2 )

World’s first autonomous shipping company launched in Norway

Comments Off on World’s first autonomous shipping company launched in Norway

Two Norwegian shipping giants, Wilhelmsen and Kongsberg, have joined together to create what they’ve described as the world’s first autonomous shipping company. “As a world-leading maritime nation, Norway has taken a position at the forefront in developing autonomous ships,” Wilhelmsen CEO Thomas Wilhelmsen told the Maritime Journal . “Through the creation of the new company named Massterly, we take the next step on this journey by establishing infrastructure and services to design and operate vessels, as well as advanced logistics solutions associated with maritime autonomous operations.” The corporate collaboration, which brings a combined 360 years of experience to the shipping game, promises affordable prices through automated efficiency. “Massterly will reduce costs at all levels and be applicable to all companies that have a transport need,” said Wilhelmsen. Kongsberg is set to provide its technological expertise while Wilhelmsen will offer its logistics and ship management operations experience.  The autonomous ships will be monitored and modified at control centers, which will be established on land.

The electric ship  began its first journey in May 2017 and will become fully autonomous by 2020. In the meantime, it will host an on-board crew, then be remotely operated. The ship cost about $25 million to build, and its first shipping mission cost almost three times as much as a traditional ship; however, it is projected to save up to 90% in annual operating costs of labor and fuel. The Yara Birkeland was created through a collaboration between agricultural firm Yara International and Kongsberg. The companies plan to roll out larger, more robust autonomous ships once regulations are in place. Globally, the job impacts of autonomous ships are expected to be far less extensive than those of autonomous trucks . Via Maritime Journal  and Fortune Images via Kongsberg

Astronomers spot the most distant star ever seen 9 billion light-years away

The Environmental Protection Agency is poised to undo Obama -era greenhouse gas emission regulations and fuel economy standards that were designed to encourage the development of cleaner, more efficient vehicles. EPA administrator Scott Pruitt will likely describe the move as lifting burdensome regulations on automakers to support the production of cheaper vehicles, but it doesn’t account for the costs of increased air pollution and continued climate change. Left in place, the rules would have reduced oil consumption by about 12 billion barrels while reducing carbon dioxide pollution by about six billion tons over the lifetime of vehicles produced under the regulations. The rules that are set to be rolled back under the Trump Administration were created in 2012 as one of President Obama’s major initiatives to combat climate change . If allowed to be fully implemented, the rules would have required automakers to nearly double the average fuel economy of new cars and trucks to 54.5 miles per gallon by 2025. Some worry that the United States ‘s decision to step away from stricter emissions standards could set a dangerous precedent around the world. “The concern is that automakers will go around the world basically trying to lobby regulators, saying, look, because the United States has reduced the pace, everywhere else should too,” Anup Bandivadekar, a researcher at the International Council on Clean Transportation, told the New York Times . Related: Congress rejects Trump’s renewable energy budget cuts While American automakers had initially lobbied the Trump Administration for more relaxed standards, they did not expect to see a complete repeal of the rules. “We didn’t ask for that,” claimed Robert Bienenfeld , assistant vice president for environment and energy strategy at American Honda Motor. “The position we outlined was sensible.” In a blog post, Ford Motor Company chairman Bill Ford and CEO Jim Hackett wrote that “we support increasing clean car standards through 2025 and are not asking for a rollback.” The relaxed standards proposed by automakers were viewed as less likely to cause a showdown with California and the dozen other states that follow its lead on strict environmental standards. Now, California is preparing for battle. “We’re going to defend first and foremost existing federal greenhouse gas standards,” California Attorney General Xavier Becerra told the New York Times . “We’re defending them because they’re good for the entire nation. No one should think it’s easy to undo something that’s been not just good for the country, but good for the planet .” Via the New York Times Images via Depositphotos and the White House

Meridian Line launches ethically sourced, organic cotton jeans for the outdoors

Comments Off on Meridian Line launches ethically sourced, organic cotton jeans for the outdoors

Adventure calling? Gear up with Meridian Line, a range of eco-friendly denim designed for conquering the great outdoors. Available for pre-ordering through Kickstarter , the men’s and women’s jeans infuse ethically sourced organic cotton with two percent spandex to allow “freedom of movement without looking like you just stepped out of yoga class,” according to the Kansas City, Missouri–based firm. Meridian Line is the brainchild of artist Jeremy Collins, who launched the company with a series of graphic T-shirts and accessories in 2014. Two years later, Collins enlisted Benji Thrasher, formerly the lead designer at Prana , to kick Meridian Line’s offerings up a notch; the jeans emerged from the drawing board shortly after. But active performance isn’t the denim’s only twist. Each pair of pants also boasts artwork by Collins on the inner pockets, yoke, and turn-ups. The print is based on one of Collins’s signature pieces: a greenery-ringed compass inset with a salmon and an eagle at play (or perhaps prey?) in a yin-yang configuration. Meridian Line’s denim is “built for outdoor activities, travel, and a casual, dareful, or professional lifestyle,” Collins and Thrasher said. “Our jeans are made to go wherever you do: urban, mountain, or board meeting.” Prices for both men’s and women’s styles start at an accessible $79, or 20 percent less than what the jeans will cost when they hit retail outlets later this year. If you’re looking for the whole top-to-toe look, a pledge of $105 will snag you a pair of jeans, an exclusive tee, and a trucker hat. + Meridian Line at Kickstarter + Meridian Line
