The Geminid meteor shower peaks this week, so hope for clear skies that will let you see a beautiful show of green fireballs on Thursday and Friday. This will be the last -- and strongest -- meteor shower of the year, according to NASA.This phenomenon was first recorded in 1862 and causes a show each December.In the hours before sunrise Friday, the most meteors will be visible in the North American sky, peaking about 7:30 a.m. ET, predicts Sky & Telescope. To see when they will peak in your part of the world, check here.But the morning isn't your only chance. On Thursday and Friday, keep an eye on the sky a few hours after sunset -- just keep the moon at your back.Although the Geminid shower is known for its "shooting stars," the number of meteors visible depends on the time and how dark it is. There will be fewer of them earlier in the evening, but the shower should hit a maximum of about 100 per hour around 2 a.m., NASA said. For those in the suburbs, expect about 30 to 40 per hour. And if you're in a city like New York, San Francisco or Atlanta, you probably won't see anything.Early evening meteors may be longer, with dramatic streaks that last several seconds. Later on, the meteors will present quicker streaks or leave trails of smoke that appear to glow.The asteroid 3200 Phaethon is responsible for this meteor shower, which is unusual because comets usually create meteor showers with icy debris. Scientists have debated the very nature of what Phaethon is. The closely tracked near-Earth asteroid has been likened to comets, so it's been called a "rock comet."Phaethon was discovered in October 1983 and named after the Greek myth about the son of Helios, the sun god, because it closely approaches our sun.Phaethon orbits the sun closer than any other asteroid and takes 1.4 years to orbit it. The asteroid heats to about 1,300 degrees Fahrenheit on closest approach to the sun, which causes it to shed dusty debris.These particles cause the meteor shower when they plunge into Earth's atmosphere at 22 miles per second, vaporizing in the streaks we call "shooting stars."If you live in an urban area, you may want to drive to a place that isn't littered with city lights that will obstruct your view. If you're able to find an area unaffected by light pollution, meteors could be visible every couple of minutes from 10 p.m. until dawn.Find an open area with a wide view of the sky, and don't forget to bundle up. Make sure you have a chair or blanket so you can look straight up. And give your eyes about 20 to 30 minutes to adjust to the darkness -- without looking at your phone -- so meteors are easier to spot.While you're keeping an eye out for the meteor shower, you might see a small, foggy green patch in the sky, NASA said. That will be Comet 46P/Wirtanen, which is making its closest approach to Earth -- within 7 million miles -- for the next 20 years. And it will be visible to the naked eye. The comet is expected to come closest to Earth and peak Sunday. 3007

The classified ads website Backpage.com has been seized by federal law enforcement agencies, according to a banner that popped up on the site Friday.The banner says, "backpage.com and affiliated websites have been seized as part of an enforcement action" by the FBI, US Postal Inspection Service and the IRS Criminal Investigation Division.Lawmakers on Capitol Hill and advocacy groups have long called for an investigation into Backpage.com for allegedly facilitating prostitution and sex trafficking.A spokesperson for the Justice Department confirmed to CNN that the website has been seized and that additional information would be made available Friday evening. However, a judge decided that the federal case should remain sealed on Friday night. No other additional information was provided.A two-year Senate investigation into online sex trafficking found that found that Backpage.com knowingly aided criminal sex trafficking of women and young girls, simply scrubbing terms from ads such as "Lolita," "teenage," "rape," "amber alert," and publishing them on its site. After the investigation was published in January 2017, Backpage.com shut down its adult ads section.The company has been targeted with several lawsuits over the years, but has been largely protected by Section 230 of the 1996 Communications Decency Act, a legal protection that gives a broad layer of immunity to online companies from being held liable for user-generated content. Companies are supposed to act in good faith to protect users, but critics argue the law can be used as a shield. The law, however, does not, protect sites from federal liability against criminal law, like child-pornography laws.Last month, however, the Senate approved bipartisan legislation called the Stop Enabling Sex Traffickers Act. The legislation would create an exception to Section 230, which would pave the way for victims of sex trafficking to hold websites accountable for facilitating abuse.Two days after the Senate approval, Backpage competitor Craigslist removed its personal ads section.The-CNN-Wire 2080

The China tariffs are back on.On Tuesday, the White House said the administration would proceed with its proposal to impose 25 percent tariffs on billion worth of goods from China, and place new limits on Chinese investments in US high-tech industries.The decision comes after top administration officials have tried to dampen fears of a trade war.Treasury Secretary Steven Mnuchin said a trade war with China was "on hold" less than 10 days ago. And Commerce Secretary Wilbur Ross is expected in Beijing on Saturday to help ease trade tensions between the two major trading partners.Beijing has previously pledged to retaliate against the 25 percent tariffs.In a brief statement, the White House said the president plans to take "multiple steps" to protect domestic technology and intellectual property from certain "discriminatory and burdensome trade practices by China."The latest step follows a March report by the US Trade Representative Office, which undertook a seven-month investigation of China's handling of technology transfers and intellectual property, according to the White House's statement."The United States will implement specific investment restrictions and enhanced export controls for Chinese persons and entities related to the acquisition of industrially significant technology, the White House said in a statement.The final list of covered imports subject to tariffs will be announced by June 15. Those tariffs will take effect "shortly thereafter."Proposed investment restrictions will be announced by June 30 and also take effect at a later date.The-CNN-Wire 1603

  

The Danish government said they plan to kill 15 million minks after the animals spread a coronavirus mutation to humans.In a press release, Prime Minister Mette Frederiksen said that a mutation of the virus has already spread from the infected minks to 12 people in North Jutland.Frederiksen added that the virus could spread to other countries and "carry the risk that the upcoming vaccine will not work as it should.""Denmark has a responsibility to our population," Frederiksen said in the news release. "With the mutation that has now been established, we now also have a greater responsibility for the rest of the world. A mutated virus risks being spread from Denmark to other countries. Therefore, we must take the situation on the Danish mink farms extremely seriously." 786

  

The demand for mail-in ballots is surging. Election workers need training. And polling booths might have to be outfitted with protective shields during the COVID-19 pandemic.As officials prepare for the Nov. 3 election, one certainty is clear: It’s coming with a big price tag.“Election officials don’t have nearly the resources to make the preparations and changes they need to make to run an election in a pandemic,” said Wendy Weiser, head of the democracy program at the Brennan Center for Justice. “We are seeing this all over the place.”The pandemic has sent state and local officials scrambling to prepare for an election like few others, an extraordinary endeavor during a presidential contest, as virus cases continue to rise across much of the U.S.COVID-related worries are bringing demands for steps to make sure elections that are just four months away are safe. But long-promised federal aid to help cash-starved states cope is stalled on Capitol Hill.The money would help pay for transforming the age-old voting process into a pandemic-ready system. Central to that is the costs for printing mail-in ballots and postage. There are also costs to ensure in-person voting is safe with personal protective equipment, or PPE, for poll workers, who tend to be older and more at risk of getting sick from the virus, and training for new workers. Pricey machines are needed to quickly count the vote.Complicating matters is President Donald Trump’s aversion to mail-in balloting. With worrisome regularity, he derides the process as rigged, even though there’s no evidence of fraud and his own reelection team is adapting to the new reality of widespread mail-in voting.“As cases of coronavirus in this country rise, it’s vital that all voters be able to cast their ballots from home, to cast their ballots by mail,” said Sen. Amy Klobuchar, D-Minn.A huge COVID response bill passed by the House in May contains a whopping .6 billion to help states with their elections, but the Senate won’t turn to the measure until late July. Republicans fought a 0 million installment of election aid this March before agreeing to it.But key Senate Republicans seem likely to support more election funding, despite Trump’s opposition, and are even offering to lower a requirement that states put up “matching” funds to qualify for the federal cash.“I’m prepared not only to look at more money for the states to use as they see fit for elections this year, but also to even consider whatever kind of matching requirement we have,” said Roy Blunt, R-Mo., chairman of the Senate panel with responsibility for the issue. “We can continue to work toward an election that produces a result that people have confidence in and done in a way that everybody that wants to vote, gets to vote.”The pandemic erupted this spring in the middle of state primaries, forcing many officials to delay their elections by days, weeks and even months. They had to deal with a wave of poll worker cancellations, polling place changes and an explosion of absentee ballots.Voting rights groups are particularly concerned with the consolidations of polling places that contributed to long lines in Milwaukee, Atlanta and Las Vegas. They fear a repeat in November.As negotiations on the next COVID relief bill begin on Capitol Hill, the final figure for elections is sure to end up much less than the .6 billion envisioned by the House. That figure followed the recommendations of the Brennan Center to prepare for an influx of absentee ballots while providing more early voting options and protecting neighborhood polling places.Even before the pandemic, election offices typically work under tight budgets. Iowa Secretary of State Paul D. Pate, who serves as president of the National Association of Secretaries of State, said the group has been calling on the federal government to provide a steady source of funds, particularly to help address ongoing costs of protecting the nation’s election systems from cyberthreats.For Georgia’s primary last month, election officials spent .1 million of the roughly .9 million the state has received in federal funds. The money was used to send absentee ballot applications to 6.9 million active registered voters and print absentee ballots for county election offices. Some of it also was used to purchase PPE and secure drop-off boxes for counties.Meanwhile, the state elections division has seen a ,000 reduction for the current budget year as Georgia — like the rest of the nation — deals with a decline in revenues due to the pandemic.The state’s remaining federal funds will be used to help cover the costs of developing an online system for voters to request absentee ballots, a less expensive option than sending ballot applications to every voter, and exploring whether installing plexiglass dividers around voting machines could allow more voters in a polling place at one time.In Colorado, which is already a universal vote-by-mail state, the Denver election office has had to reduce its budget by 7.5%, which amounts to nearly 0,000. Jocelyn Bucaro, Denver’s elections director, said the federal funds sent earlier this year helped with purchasing PPE and other pandemic-related supplies.Iowa similarly spent its federal dollars on mail-in ballots and pandemic supplies, Pate said.Vote-by-mail veterans and vendors of the equipment, software, ballots and envelopes that will be needed in November say the window to buy them is quickly closing.“Right now, what I’m seeing in most places is just this kind of indecision. What are we supposed to be planning? Vote by mail or in-person or combination?” said Jeff Ellington, president of Runbeck Election Services, which prints ballots and the special envelopes used to mail them and also supplies high-volume envelope sorters.“Decisions just need to be made so people can start to put a plan into place,” he said.BlueCrest, a Pitney Bowes spinoff, sells high-volume sorting machines that handle up to 50,000 ballot envelopes per hour. That’s the kind of crunch big counties can expect to face on Nov. 3 in states including Wisconsin and Pennsylvania, where Rick Becerra, a vice president at the company, said he’s been talking to officials. The machines average 5,000 each.“I tell them the time is now,” he said.___Cassidy reported from Atlanta. Associated Press writer Frank Bajak in Boston contributed to this report. 6414
