Jupiter and Saturn, the two largest planets in the Solar System, were stationed in nearly the same spot in the night sky on Monday, creating a bright spectacle.The positions of the two planets align once every 20 years, according to NASA. While conjunctions happen several times during the course of a typical lifetime, a conjunction of this magnitude is quite rare. The last time the two planets were this close to each other in the night sky was 400 years ago, but no one was able to see it as that conjunction occurred during the day.The last time a conjunction of his magnitude happened at night was 800 years ago.So what causes the conjunction?“You can imagine the solar system to be a racetrack, with each of the planets as a runner in their own lane and the Earth toward the center of the stadium,” said Henry Throop, astronomer in the Planetary Science Division at NASA Headquarters in Washington. “From our vantage point, we’ll be able to be to see Jupiter on the inside lane, approaching Saturn all month and finally overtaking it on December 21.”The timing of the conjunction adds to the spectacle. Monday also marks the winter solstice.Being four days before Christmas, some are dubbing the event as “The Christmas Star,” although the conjunction is of planets and not stars. Scientists have long speculated whether the Star of Bethlehem was the 7 BC conjunction of the two planets.“Conjunctions like this could happen on any day of the year, depending on where the planets are in their orbits,” said Throop. “The date of the conjunction is determined by the positions of Jupiter, Saturn, and the Earth in their paths around the Sun, while the date of the solstice is determined by the tilt of Earth’s axis. The solstice is the longest night of the year, so this rare coincidence will give people a great chance to go outside and see the solar system.”While the two planets will have the appearance of being very close to each other, in reality, they will be hundreds of millions of miles apart.For the next few days, Saturn and Jupiter will remain very close to each other in the night sky. The best time to view the planets will be roughly one hour after sunset in the southwest sky. Jupiter will appear to be brighter than Saturn as its closer and larger. 2278

Kevin McKay drove the school bus along gridlocked, dark roads as pockets of fire burned all around. Nearly two dozen elementary school children were on board with him.Smoke began to fill the bus, so McKay took off a shirt. He and two teachers on the bus tore it into pieces and doused them with water. The children held the damp pieces of cloth to their mouths and breathed through them.He had only been on the job, driving the bus for Ponderosa Elementary School in the northern California city of Paradise, for a few months. Now, McKay was ferrying the 22 stranded children to safety as the Camp Fire scorched everything in its path. It would take five harrowing hours for them to reach safety.The fire had broken out early on the morning of November 8, around 6:30 a.m., forcing many to evacuate Butte County.McKay, 41, grew concerned early on. He had seen wildfires before, he said. "But the fact that it was coming down in 1,000 places, it was unheard of," McKay told CNN in an interview Sunday in a park in Chico, a city southwest of Paradise.He saw flames approach the school in both directions.His son, mom and girlfriend had already evacuated to a hotel in Chico that morning. "That freed me up to focus completely on this terrifying situation," McKay said.Family members of most other students had already picked up their children.But nearly two dozen students were stranded because their family members hadn't made it to the school. McKay discussed evacuating the students with Ponderosa's principal. 1519

KANSAS CITY, Mo. —  Multiple officials in Leavenworth County, Kansas are urging a county commissioner to resign after the white commissioner told a black woman at a meeting that he was part of "the master race."Leavenworth County Commissioner Louis Klemp made the comments at a meeting about a land-use study on Tuesday."I don’t want you to think I am picking on you because we are part of the master race. You have a gap in your teeth. We are part of the master race, don’t you forget that," Klemp said.  “It affects all of Leavenworth. This has been such negative publicity. It affects us. It affects the city,” Leavenworth mayor Mark Preisinger said. “It’s a stain on our community and it has to be removed.” "I was shocked. I was in disbelief," fellow commissioner Robert Holland said. "He should resign. I don't care if he's got two days left, he should resign." Klemp did not respond to a formal request for an interview, though he implied off-camera that he meant the comment as a jokeThis is not the first time the commissioner's remarks have sparked controversy. Last year, while discussing the county's holiday schedule, Klemp made controversial remarks about Robert E. Lee and George Washington."Not everybody does them all because we have Robert E. Lee...Oh God Robert E. Lee...wonderful part of history," Klemp said. "It bothers me that if we're going to have Martin Luther King Day, why don't we have a George Washington? I think George was a pretty important guy," he later added. Klemp was appointed as commissioner after Clyde Graeber resigned for health reasons.Klemp's last day as commissioner is Jan. 15. "I'm ashamed of one of our commissioners and what he has done. We shouldn't be labeled as Leavenworth County, the racist county. That's the way I feel we are being labeled," Holland said.  1901

KENOSHA, Wis. — A Wisconsin high school teacher is on paid leave after students recorded her using a racial slur on camera during class.The teacher can be heard repeatedly using the “N-word” several times while students in the class laugh. The parent of the student who took the video told WTMJ the incident started when a student at Bradford High School in Kenosha, Wisconsin used the word with another student.That’s when the parent said the teacher used the slur and said that she should be able to use it because it is used within the African-American community. At Tuesday’s Kenosha Unified School District board meeting, representatives from the community’s Coalition for Dismantling Racism spoke about the incident.“Our concern is the total lack of action from the administration. This should have been addressed immediately. Especially when several students stated how uncomfortable they were in the classroom. A teacher should not make her students uncomfortable particularly when you’re talking about something as sensitive as using a racial slur,” Darrell Greene said. The parent of the student who shot the video says he turned it over to the school’s principal immediately after it was shot on November 29, but in a statement to  the district said: 1309

JACKSONVILLE, Fla. (AP) -- Court records show that a man accused of killing two people and then himself at a video gaming competition in Florida had been hospitalized for mental illness, according to the Associated Press. Divorce filings from the parents of 24-year-old David Katz of Baltimore say that as a teenager he was twice hospitalized in psychiatric facilities and that he was prescribed anti-psychotic and anti-depressant medications.The records show Katz's parents disagreed deeply on how to care for their troubled son.Katz's father claimed his estranged wife was exaggerating symptoms of mental illness as part of the couple's long-running and acrimonious custody battle. They divorced in 2007.Authorities say Katz killed two people and wounded nine others Sunday before fatally shooting himself at the "Madden NFL 19" tournament in Jacksonville. 876
