Look up at the sky this week. We will get a treat as Jupiter and Saturn will be the closest they have been in the sky in four centuries. Appearing as a “Christmas star,” the "great conjunction" happens next Monday, December 21, which also happens to be the Winter Solstice, marking the start of the winter season. A conjunction happens when planets appear close in the night sky and line up with Earth’s orbits. The last time Jupiter and Saturn were this close was 1623, about 14 years after Galileo was using rudimentary telescopes to study outer space. However, that year, the conjunction was too close to the sun to view it. The last time Jupiter and Saturn were this close and visible to the Earth was during the Middle Ages in 1226. 746

LONDON — America’s top infectious disease has apologized for suggesting authorities in the United Kingdom rushed their authorization of a COVID-19 vaccine, saying he has “great faith” in the country’s regulators.Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, had sparked controversy with an earlier interview in which he said U.K. regulators hadn’t acted “as carefully” as the U.S. Food and Drug Administration.Fauci said late Thursday that he meant to say U.S. authorities do things differently than their British counterparts, not better, but his comments weren’t phrased properly.Fauci told the BBC: “I do have great faith in both the scientific community and the regulatory community at the U.K., and anyone who knows me and my relationship with that over literally decades, you know that’s the case.”After Fauci’s original comments, U.K. regulators went on the offensive. The Medicines and Healthcare Products Regulatory Agency said Friday that its personnel rigorously analyzed data on safety and effectiveness in the shortest time possible without compromising the thoroughness of their review.The agency's comments came as the Times newspaper reported that the agency’s chief executive would give a series of radio interviews so she can speak directly to people who may be concerned about being vaccinated.The media blitz comes after amid concerns that criticism of the approval process could undermine public confidence in the Pfizer/BioNTech vaccine, leading some individuals to shun shots. 1551

LOS ANGELES (AP) — Scientists say earthquakes that hammered the Southern California desert last summer involved ruptures on a web of interconnected faults and increased strain on a major nearby fault that has begun to slowly move.Research published Thursday in the journal Science says the earthquake sequence ended a few miles from the Garlock Fault, which runs 185 miles (300 kilometers) from the San Andreas Fault to Death Valley.The fault has been relatively quiet for 500 years but now has begun to creep.The quakes began July 4 near Ridgecrest, about 120 miles (190 kilometers) north of Los Angeles.A magnitude 6.4 foreshock was followed by a 7.1 mainshock and 100,000-plus aftershocks.The study was conducted by geophysicists from California Institute of Technology and NASA's Jet Propulsion Laboratory. 818

LOS ANGELES (AP) — The western Joshua tree needs protection under the California Endangered Species Act because of threats from climate change and habitat destruction, the Center for Biological Diversity said in a petition Tuesday to the state's Fish and Game Commission.The petition comes amid rising concern about the future of the crazy-limbed trees with spikey leaves that have come to symbolize the Mojave Desert and draw throngs to Joshua Tree National Park."The state has to step up for these trees," center conservation director Brendan Cummings said in a statement.The petition asks that western Joshua trees be given "threatened" status under the act.The request states that the trees meet the definition of a plant that "is likely to become an endangered species in the foreseeable future in the absence of the special protection and management efforts."Researchers have found that Joshua trees are dying off due to hotter and drier conditions, and fewer young trees are surviving, according to the center, a nonprofit conservation organization based in Tucson, Arizona.The trees are migrating to higher elevations where there are cooler and more moist conditions, but they face destruction by fire due to invasive, non-native grasses in those locations.Joshua trees also face challenges due to urban sprawl in the desert as well degradation of habitat for energy projects, powerlines, pipelines and off-road-vehicle use.The western Joshua tree's habitat includes Joshua Tree National Park and stretches to the west along the north slopes of the San Bernardino and San Gabriel mountain ranges into the Antelope Valley, northward along the eastern flank of the southern Sierra Nevada and eastward toward the edge of Death Valley National Park and into Nevada.The eastern Joshua tree — a distinctly different plant — lives in the Mojave National Preserve and eastward into Nevada, Arizona and Utah.The Center for Biological Diversity said that under the California Endangered Species Act, the state Department of Fish and Wildlife has three months to make a recommendation to the Fish and Game Commission, which would then vote on the petition next year. 2171

LOS ANGELES (AP) — After weeks of stressing education over enforcement, California communities are issuing fines and relying on anonymous tips to make sure businesses and residents are complying with health orders amid the coronavirus pandemic. Los Angeles County, the state’s most populous, is averaging 2,000 reports a week on its tip lines with complaints ranging from a lack of hand sanitizer to improper cleaning of workplace bathrooms. California on Thursday reported nearly a half-million confirmed virus cases since March, the most in the nation, and 391 deaths were tallied over the last two days, the highest since the start of the pandemic. 659
