(KGTV) - Did an HOA really order a Texas family to take down the inflatable snowman in their front yard because it's too early for Christmas decorations?Yes!In addition to the snowman, the Simonis family has a reindeer and a Santa helicopter in their yard.On November 4th, the HOA sent them a letter saying they needed to remove the snowman until closer to the holiday season. Exactly when "closer" is wasn't specified.Claudia Simonis is due to give birth December 25th and wants her children to be able to celebrate Christmas early. So the family has no intention of removing their decorations.They have the full support of their neighbors who are putting up their decorations early in solidarity. 707

(KGTV) -- Costco is again adjusting store hours to accommodate seniors and other vulnerable groups.The wholesale retailer’s Special Operating Hours are typically 9 a.m.-10 a.m., Monday-Friday. The timeframe applies to customers 60 years of age and older and those with disabilities or who are immunocompromised, store officials said.However, citing the surge in COVID-19 cases across the country, Costco is moving its Special Operating Hours to 8 a.m.-9 a.m. at specific locations.The following San Diego County locations will move its Special Operating Hours to 8 a.m.-9 a.m.:Carmel MountainMission ValleyRancho Del Rey (H St., Chula Vista)Costco was one of the first retailers to require masks in its stores.Last month, Costco stopped allowing exemptions for mask-less shoppers citing medical conditions. 814

(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) — A California Highway Patrol officer found himself in the right place at just the right time this week on a Northern California freeway.CHP officer Jeffrey Lloyd was completing a traffic stop on State Route 99 Monday when an SUV pulled up behind him. A woman in the right passenger seat was going into labor and about to give birth, according to CHP'S South Sacramento office.Officer Lloyd informed dispatch of the situation and gatherer medical equipment to help deliver the baby right there on the freeway. RELATED: San Diego welcomes first baby of 2019 in Chula VistaAs soon as he made it back to the vehicle, he began comforting the mother and helped deliver the newborn girl, CHP says."He carefully unwrapped the umbilical cord from the baby’s head and made sure both mother and baby were stable," according to South Sacramento CHP. "Officer Lloyd notified dispatch of the birth and stayed with the mother and baby until medical personal from the Sacramento City Fire Department arrived on scene."The mother and newborn were transported to a nearby hospital and were said to be in excellent health and resting Tuesday. 1139
