(CNN) -- Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist.It's a stellar black hole — the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because as these stars die, they lose most of their mass through explosions that expel matter and gas swept away by stellar winds.This theory has now been toppled by LB-1, the newly-discovered black hole. Located about 15,000 light years away, it has a mass 70 times greater than our sun, according to a press release from the Chinese Academy of Sciences.The findings were published by Chinese researchers in the journal Nature on Wednesday."Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution," said Liu Jifeng, head of the team that made the discovery. "LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation."Scientists are now scratching their heads at how LB-1 got so huge.The Chinese team has proposed a number of theories. LB-1's sheer size suggests that it "was not formed from the collapse of only one star," the study said -- instead, it could potentially be two smaller black holes orbiting each other.Another possibility is that it formed from a "fallback supernova." This is when a supernova -- the last stage of an exploding star -- ejects material during the explosion, which then falls back into the supernova, creating a black hole.This fallback formation is theoretically possible, but scientists have never been able to prove or observe it. If this is how LB-1 formed, then we may have "direct evidence for this process" for the first time, the study said.LB-1 is not the biggest black hole ever discovered -- but it may be the largest of its kind. There are several types of black holes, and stellar black holes like LB-1 are on the smaller side, according to NASA. Supermassive black holes are much bigger -- they can be billions of times the mass of our sun.Scientists believe supermassive black holes may be connected to the formation of galaxies, as they often exist at the center of the massive star systems -- but it is still not clear exactly how, or which form first.Stellar renaissanceStellar black holes are believed to be commonly scattered across the universe, but they are difficult to detect because they do not normally emit X-rays -- only doing so when they gobble up gas from a star that has ventured close enough. They are so elusive that scientists have only found, identified, and measured about two dozen stellar black holes, the press release said.The researchers at the Chinese Academy of Sciences tried a different approach. Instead of looking for X-rays emitted by black holes, the team looked for stars that were orbiting some invisible object, being pulled in by its gravity.Their efforts paid off -- they soon spotted a giant star eight times heavier than the sun, orbiting around what turned out to be LB-1."This discovery forces us to re-examine our models of how stellar-mass black holes form," said David Reitze, a physicist at the University of Florida. In May, Reitze's team made its own breakthrough discovery -- observing the never-before-seen collision of a neutron star and a black hole, which sent out ripples in space and time.These twin discoveries -- the collision, and now LB-1 -- indicate that scientists are reaching "a renaissance in our understanding of black hole astrophysics," said Reitze in the press release.There have been several other discoveries over the past year that have added to this renaissance. In October, researchers discovered what they believe to be a new type of black hole, smaller than the other kinds. And earlier this week, astronomers discovered a black hole that is actually helping baby stars grow instead of destroying them. 3971

(KGTV) — Every New Year's Eve, there's one thing humans look forward to and canines dread: Fireworks.And the threat to our four-legged friends is real, as thousands of dogs disappear from homes every year on holidays like New Year's Eve and the Fourth of July due to fireworks.Enter Ford's prototype noise-canceling dog kennel. The kennel uses the same technology found in vehicles and headphones in order to protect dogs' sensitive ears from fireworks that could cause them to panic.Here's how it works: Microphones inside the kennel detect the sound of a firework and then omit an opposing frequency to cancel out the noise or reduce it almost entirely. The walls of the kennel are designed using high-density cork in order to add another degree of silence.The result is a futuristic-looking kennel that keeps canines content amid the "booms" and "crackles" of fireworks:The prototype was inspired by some of the cabin technology Ford employs in its own vehicle designs.“We wondered how the technologies we use in our cars could be applied to help in other situations. Could dogs enjoy quieter New Year’s Eve celebrations through the application of our Active Noise Control system? We have a few more ideas in progress as to how our everyday lives might benefit from a little Ford know-how,” said Lyn West, brand content manager, Marketing Communications, Ford of Europe.RELATED: Latest in electric, exotic, everyday vehicles rolls into San Diego Auto ShowOf course, while the kennel is a mere prototype, that doesn't mean the idea can't be deployed on a larger scale. Soundproofing dogs crates have gained their own DIY following online and their are already products available online. This may, however, be the first time an automotive manufacturer has taken the technology we use on a daily basis and applied it on a smaller, more adorable scale. 1859

(KGTV) — An elderly driver led Los Angeles-area officers on a slow-speed pursuit on the 101 Freeway Wednesday, before being taken into custody.The driver began the pursuit with California Highway Patrol officers just after 1 p.m. in the San Gabriel Valley area, according ABC-affiliate KABC. CHP officers tried to pull the driver's SUV over for a carpool violation but the vehicle continued down the freeway, KABC reported.Officers followed the driver at normal highway speeds through Glendale and into the San Fernando Valley, before officers pulled in front of the driver's SUV and slowed the vehicle down.As officers approached the vehicle, the driver was cooperative and stepped out of the vehicle without incident.The driver, who appeared to be an elderly man, seemed disoriented as officers took him into custody, KABC reported. 842

(KGTV) - Did the Transportation Department really declare that airlines must allow miniature horses to fly as service animals?Yes.The new guidelines add miniature horses to the list of service animals that can fly in any cabin.The horses stand 2 to 3 feet tall and weigh about 100 pounds.The Department does note that airlines are still allowed to reject animals if they're deemed too large, dirty, or dangerous. 420
