(KGTV) — A travel warning for Americans traveling to Mexico was issued Wednesday, ahead of the expected annual Spring Break travel rush.The alert, issued by the U.S. Embassy & Consulates in Mexico, warned U.S. citizens of a list possible dangers, including unregulated alcohol, sexual assault, medical emergencies, and breaking the law in Mexico."Each year, thousands of U.S. citizens visit Mexico during Spring Break. While the vast majority of travelers have safe and enjoyable trips, Spring Break travel can sometimes include unforeseen problems," the alert read.The alert recommended travelers check their health plans for coverage overseas or in Mexico, practice safe behavior when swimming at local beaches, drink responsibly and watch drinks at all times, stick close to friends, be aware when traveling around the country, and protect personal possessions.Anyone who needs assistance is encouraged to contact the nearest U.S. Embassy or Consulate. 968

(KGTV) — A magnitude 6.6 earthquake shook parts of the Southern Philippines Tuesday morning local time, weeks after another deadly quake struck the region.Tuesday's quake hit just after 9 a.m. on the island of Mindanao near the town of Tulunan in North Cotabato, according to the Philippine Institute of Volcanology and Seismology.Damages and aftershocks were expected, CNN reported, and several evacuations were reported.The earthquake comes about two weeks after a 6.3-magnitude quake killed seven people and injured dozens in the same town in North Cotabato, CNN reported. 583

(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
