Cool, Gassy ‘Disk’ Spotted Around Milky Way’s Supermassive Black Hole

first_img Scientists Find ‘Hungry’ Supermassive Black Hole Eating 3 Meals DailyScientists Behind First Black Hole Image Win $3 Million Prize Stay on target The neighborhood surrounding the Milky Way’s supermassive black hole is bustling with cosmic and gaseous activity, however, astronomers have not been able to capture most accreting gas movement. Now, new Atacama Large Millimeter/submillimeter Array (ALMA) observations have detected a cool, interstellar gas “ring” surrounding the supermassive black hole, which has never been seen before.Researchers, which published their findings in the journal Nature on June 5, are exploring this strange nebulous “disk,” which could provided additional information on how accretion, the siphoning of material onto a black hole’s surface, works in space, said a National Radio Astronomy Observatory (NRAO) press release.For decades, astronomers have analyzed the crowded area around the supermassive black hole, which is located at the heart of the Milky Way. According to NRAO, our galactic center is roughly 26,000 light-years from our planet and the supermassive black hole (Sagittarius A*) is four million times the mass of the sun. This space is quite chaotic with interstellar dust clouds, roving stars, and a massive reservoir of phenomenally hot and comparatively colder gases and these gases are supposed to circle the supermassive black hole in a vast accretion “ring,” which is nearby the supermassive black hole’s event horizon.ALMA image of the cool hydrogen gas ring circling the supermassive black hole at the heart of the Milky Way galaxy.

Dagnello)Before the ALMA image, astronomers were only able to image the hot, glowing portion of the accreting gas flow, which showed no rotation and has an approximate temperature of 18 million degrees Fahrenheit. Previous observations with millimeter-wavelength telescopes have also found comparatively cooler hydrogen gas (roughly 18,000 degrees Fahrenheit) located within a few light-years from the supermassive black hole and the contribution of this much cooler gas to accretion flow onto the black hole wasn’t determined yet.New @ALMAObs observations reveal a never-before-seen disk of cool, interstellar gas wrapped around the supermassive black hole at the center of the Milky Way.

Dagnello https://t.co/xxcoazEUrc pic.twitter.com/gcZLTwtF7E— ESO (@ESO) June 6, 2019Thanks to the ALMA, which was able to sense a small millimeter-wavelength signal and generate the first image of the cooler gas “ring” at roughly a hundredth of a light-year away from the supermassive black hole, astronomers can trace the motion of gas. Mapping the shifts in wavelengths of this radio light because of the Doppler Effect allowed astronomers to see the gas circling around the supermassive black hole.“We were the first to image this elusive disk and study its rotation,” Elena Murchikova, lead author on the paper, said in the press release. “We are also probing accretion onto the black hole. This is important because this is our closest supermassive black hole. Even so, we still have no good understanding of how its accretion works. We hope these new ALMA observations will help the black hole give up some of its secrets.”More on Geek.com:Astronomers Capture Image of Black Hole for the First TimeScientists May Have Detected ‘Violent’ Black Hole-Neutron Star CollisionSee What Black Hole Photos Might Look Like in the Futurelast_img read more

Stocks sink as Powell dents hopes for multiple rate cuts

first_imgStocks fell and bond yields rose on Wall Street Wednesday after the Federal Reserve lowered its key interest rate for the first time in a decade but left investors feeling uncertain about the likelihood of further cuts.The quarter-point cut announced by the central bank was widely expected, so investors focused on Chairman Jerome Powell’s remarks during a news conference for hints about the Fed’s future plans.Powell said that there could be more cuts, but that the central bank was not intending to embark on a long cycle of lowering interest rates. He characterized the rate cut as a “mid-cycle adjustment.”The remarks sent stocks into a skid that briefly knocked the Dow Jones Industrial Average down more than 470 points. Prices of short-term U.S. government bonds fell, sending yields higher.Stocks erased some of their losses later during Powell’s news conference, when he seemed to shift his message to leave open the possibility that the Fed would cut rates again.last_img read more

Clark County Sheriffs Office reaches new heights with drones

first_imgTwo years after the initial rollout, the Clark County Sheriff’s Office is expanding its drone program.The sheriff’s office first unveiled five small quadcopters, with an equal number of deputies assigned to them, as new law enforcement tools in August 2017. Since then, the sheriff’s office has added two additional, larger drones and is hoping to bring four more deputies on board by the end of the year.“This is really a game changer for us in a lot of areas in a positive way,” Sheriff’s Sgt. Pete Muller said.The original drones were DJI Mavics, small devices that are easy to carry and deploy due to their size. The sheriff’s office also has a DJI Inspire and, most recently, a DJI Matrice 210 — both larger drones that offer additional capabilities.Drones were deployed by the office 103 times last year and on 68 occasions this year as of July 25, Sheriff’s Detective Todd Young said. They are used mostly to investigate serious crash scenes, followed by search-and-rescue calls and high-risk search warrant executions that require SWAT presence. Drones allow law enforcement agencies to monitor active emergencies, such as hostage situations, from a safe distance.“You probably have a situation where an unknown person can do anything,” Sheriff’s Sgt. Jason Granneman said. “Without that overhead view, you don’t know.”Crime scene investigations and searches for missing people or fugitives may also feature the devices. Images captured by the drones can be used as evidence in criminal cases.last_img read more

Alleged Capital One hacker barely bothered to hide

first_imgSEATTLE — The 33-year-old former Amazon software engineer accused of hacking Capital One made little attempt to hide her attack. In fact, she effectively publicized it.It’s one of many riddles swirling around Paige Thompson, who goes by the online handle “erratic.” Well-known in Seattle’s hacker community, Thompson has lived a life of tumult, with frequent job changes, reported estrangement from family and self-described emotional problems and drug use.FBI agents arrested Thompson Monday for allegedly obtaining personal information from more than 100 million Capital One credit applications, including roughly 140,000 Social Security numbers and 80,000 bank account numbers. There is no evidence the data was sold or distributed to others.Thompson, in federal custody pending an Aug. 15 detention hearing, wasn’t reachable. Her public defender, Mohammad Hamoudi, did not return an emailed request for comment.But her online behavior suggested that she may have been preparing to get caught. More than six weeks before her Monday arrest, Thompson had discussed the Capital One hack online with friends in chats and in a group she created on the Slack messaging service.last_img read more

National Institutes of Health brings All of Us effort to Vancouver

first_imgClark County is part of a nationwide research effort through next week.The National Institutes of Health’s “All of Us” research program is traversing the country as part of a nationwide effort to improve medical treatment by better understanding the impacts of lifestyle, environment and biology on health, according to the NIH website.The program will be in Vancouver through Aug. 9.The research hopes to gather data from 1 million people from a broad range of backgrounds, so its findings will be comprehensive, said Mel Lopez, who is working on the NIH project.“This way, everybody can be fairly represented in medical research,” Lopez said.The globetrotting aspect of the research program is designed to speed up the process of finding 1 million participants.The study hit its one-year mark in May and has a 10-year run period. So far, more than 230,000 people have already participated, and more than 180,000 biosamples have been received. The Vancouver stop has an educational exhibit and a mobile clinic. The educational exhibit asks questions about lifestyle and environment and has a virtual reality booth teaching about the impact of medical breakthroughs.“We can personalize things by looking at your genetics, your lifestyle and your environment,” Lopez said. “If we have a pool of 1 million or more of all walks of life, we can better personalize precision medicine.”There are also private rooms for physical measurements and biosample collections, but those things are not mandatory for the research. You can still contribute to All of Us without undergoing the clinical portion by answering surveys about lifestyle and environment, Lopez said.last_img read more

Vancouver library employees still split over salaries

first_imgFort Vancouver Regional Libraries and its largest employee union remain at odds after months of contract negotiations.Members of the Washington Public Employees Association — which at the library includes 163 aides, clerks and other paraprofessional positions — are advocating for raises they say will bring their salaries in line with those of their peers in other library systems in the region.Dana Hoffman, chair of the bargaining unit, said the library’s budget staff is prioritizing the construction and expansion of new libraries over the wellbeing of employees.“I think they are so blinded by their desire to make pretty new libraries that they don’t care who they run over to get to the new library at the end,” Hoffman said.Library officials, however, say raises at the level the bargaining unit is asking for could be unsustainable in future years.“We want to support and pay our employees, but we also have a responsibility to the taxpayer,” said Amelia Shelley, executive director of Fort Vancouver Regional Libraries. “So whatever we do has to be sustainable.”The negotiations, which have been ongoing since May of 2018, center around a 2017 salary study conducted by Minneapolis-based consulting group Pontifex. The survey, which looked at compensation for similar positions at library systems throughout the Pacific Northwest, found that employees at Fort Vancouver Regional Libraries are underpaid compared with staff in other systems.last_img read more

3 rescued near Akutan after fishing vessel takes on water

first_imgAn aerial view of Akutan Harbor. (Photo: Stephanie Joyce/KUCB)Three people were rescued Monday (Feb. 13) morning after their fishing vessel ran aground near Akutan Harbor.Listen nowAfter the U.S. Coast Guard heard reports the F/V Predator was taking on water, Petty Officer John-Paul Rios said they launched a rescue by air.“A Coast Guard helicopter got on-scene, hoisted three individuals off the vessel, and transported them back to Akutan,” Rios said. “We were told they had no kind of medical conditions.”The fate of the vessel is less certain. Rios said the Predator ran aground hard, and it’s unclear whether it can be repaired.“There was an eight-inch crack in the hull of the vessel, and that’s what caused it to take on water,” Rios said. “I haven’t been notified about any pollution, but that’s something we’ll definitely keep an eye on.”Meanwhile, Rios said the Coast Guard is still searching for the F/V Destination and its six crew members. The crabbing vessel went missing Saturday morning near St. George Island.last_img read more

A Watch That Shoots Lasers Yes Please

first_img 2 min read Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global November 21, 2014 Every morning when I wake up, I wish I could shoot lasers from my wrist. Don’t you?One enterprising hobbyist heard my calls and created a watch that, yes, shoots lasers. (Weep. Tear.)The watch was built by Patrick Priebe — my new hero — using a machined metal body, a carbon-coated cover and a 1,500-miliwatt laser. As you can see in the demonstration below, the laser isn’t just some puny beam of light. It burns hot enough to pop a series of balloons.Related: Virtual Reality Meets DIY With Samsung’s Project BeyondDid I mention the watch also has an LED screen and tells time, too?One can only assume that Priebe took inspiration from James Bond, who used a laser watch in 1995’s GoldenEye to dramatically escape a train car that was about explode. Kinda cool. Why anyone would really need a laser watch is beyond explanation — other than tech-geek fantasy, anyway. Not to mention it is dangerous and probably breaks a few laws.Related: Watch This Fearless Frenchman Laugh in the Face of Death on a Rocket-Powered Bicycle at 207 Miles Per HourPriebe apparently isn’t the only person crafty (crazy?) enough to create a laser watch. Here’s a version that features a 700 miliwatt laser:And — because why not? — here’s the clip from GoldenEye where Bond blasts through the train floor with his laser watch. (It happens around the 1:10 mark, and the clip is conveniently set to video-game music.) Enjoy.Related: Gold? Silver? Pffft.

What security pros need to know from Black Hat Def Con 2019

What security pros need to know from Black Hat Def Con 2019

first_imgBlack Hat and Def Con came and went as quickly as it ever does. The week-long pair of back-to-back conferences, referred to as “hacker summer camp,” draws in the security crowd from across the world onto Las Vegas, where startups tout their technologies as hackers and researchers reveal their findings.This year we saw ordinary-looking charging cables that can hack your computer, we found out that cloud backups are easily exposed, robocall blocking apps aren’t as privacy-focused as you might think, and your corporate VPN and office printer are targets for hackers (and if they fail there they’ll just ship a hardware exploit to your mailroom.) Even students can easily hack their own school systems.The obvious takeaways might be to never plug anything into your computer and that all your data is already ‘pwned’.But what does that all mean to the average security professional, let alone the CISO at the top of the corporate chain? Between the villages and the many speaker tracks — not to mention the darting between hotels — it’s tough to know exactly what we should take away from the shows.We spoke to four security experts who were there and asked them what their primary takeaways were for security decision-makers.Internet of Things is a risk factorlast_img read more

Coming in he was the man…it was Pat Minter rec

first_img“Coming in, he was the man…it was Pat,” Minter recalled. “You thought what he did in the games was amazing, you should have seen him in practice. “He was like a big brother, he was a guy you look up to. I’m thrilled to be on the same team as him again.” – / 48 The 5: Takeaways from the Coyotes’ introduction of Alex Meruelo Derrick Hall satisfied with D-backs’ buying and selling The Cardinals followed suit and picked a linebacker of their own — Kevin Minter of LSU.“I’m a very passionate player,” Minter told Doug and Wolf on Arizona Sports 620 Friday. “I’ll go out there with an attitude. I want to make every tackle, regardless if it’s downfield or in front of me.“I’m an all-around linebacker. I’m good in pass drops, I’m good in man-to-man, but I’m really a run-stopper and I feel like I can bring a lot to the Arizona organization.” Minter had 130 total tackles, 15 tackles for loss and four sacks for a stingy LSU defense that was ninth in the nation against the run in 2012, allowing 101.68 yards per game. The Georgia native was a Butkus Award finalist and doesn’t lack for confidence on the football field.“My only weakness is my experience. I’m a rookie so I’ve got to get in there and get my feet wet,” Minter said. “The sky’s the limit for me, I feel like I can really contribute to this team.” The 6-foot-2, 245-pound linebacker played three seasons at LSU, including 2010 when he was part of a defense that featured cornerback Patrick Peterson.
