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 Department of Labor reported Thursday that 1.5 million Americans filed initial claims for unemployment during the week ending June 20, bringing a 14-week total to about 46.5 million claims.Thursday's figures were down about 20,000 from last week's unemployment filings. It marked the third straight week where unemployment claims have hovered at about 1.5 million.Weekly claims for unemployment have been falling for about three straight months after peaking at about 6 million a week in late March. But weekly unemployment claims remain historically high.Prior to the pandemic, the record high for weekly unemployment claims came in 2006, when 665,000 people filed for unemployment. The Department of Labor has been tracking the statistics since 1967.Economists often use weekly unemployment claims as a reliable tool when predicting unemployment. However, some surveys indicate that initial weekly claims may be underestimating the amount of those unemployed.At least one survey from the Economic Policy Institute found that millions of Americans gave up trying to seek benefits or didn't even attempt to due to states' overwhelmed and antiquated unemployment systems.The economy has improved slightly since the virus first arrived in the U.S. earlier this year. Every state had begun the process of restarting its economy as of earlier this month.However, new cases of COVID-19 are currently on the rise in many states, with reports of new infections nearing record levels — re-igniting fears that more lockdown restrictions could be on the way. 1560

The Federal Reserve will almost certainly raise interest rates Wednesday at Jerome Powell's first meeting as chairman.The question is what his plans will be for the central bank later this year, as the Fed wrestles with how to prevent the economy from overheating.Some hints may come when Powell and members of the Federal Open Market Committee release their revised economic forecasts. The Fed is likely to stick with its three planned rate hikes this year for now, but may hint at a fourth.The Fed will release its rate hike decision and updated forecasts at 2 p.m. ET. Powell will take questions from reporters at his first press conference a half-hour later at 2:30 p.m. ET.Powell, who began a four-year term last month, has expressed confidence that the next few years will be "good years for the economy" and that many challenges for the economy have faded into the background.That message has been echoed by Powell's colleagues on the Fed board.Fed Governor Lael Brainard, who has advocated slower rate hikes, has more recently expressed optimism about the trajectory of the economy. Those cheery comments suggest she may support faster action by the Fed to tighten monetary policy."Many of the forces that acted as headwinds to US growth and weighed on policy in previous years are generating tailwinds currently," she said earlier this month in a speech pointing to the recent fiscal stimulus from tax cuts and higher spending.Fed officials are assessing the impact of the .5 trillion tax cut enacted earlier this year. The Fed is also watching for signs that inflation is coming closer to the central bank's target of 2%.  1647

  

The family flick "Show Dogs" is getting an immediate re-cut after parents who took their children to see the movie criticized scenes they say depict sexual abuse.The edits address scenes in which the lead undercover police dog Max, voiced by Ludacris, who while being inspected at a dog show becomes comfortable with his private parts being touched, according to Deadline.In a statement, Global Road Entertainment said the revised version of the film will be in theaters this weekend:  508

  

The current spike in COVID-19 cases is stressing the testing system across the country.As the virus spreads at unprecedented rates, more Americans are seeking COVID-19 tests. But in recent days, companies that make the tests and the supplies needed for them are struggling to keep up with demand."Those companies were operating on an allocation basis, and that just means that basically everything they make is going out the door," said Kelly Wroblewski, the Director of Infectious Disease Programs at the Association of Public Health Laboratories. "There is no reserve, so there's an increased demand in a lab for testing. There's no more reagent to be had, so to meet that demand, that lab has to use a different manufacturer's test."Wroblewski adds that along with issues in getting supplies, officials are also short on human resources — there is only so much lab capacity and only so many trained people to conduct the tests.The American Clinical Laboratory Association says the surge in demand for testing means some labs could reach or exceed their current testing capacities soon — meaning it could take longer for patients to get PCR test results back.Wroblewski says that it can take currently take anywhere from 24 hours to a week to get PCR test results back.With antigen tests, patients can get results back in less than 30 minutes. There is currently enough of a supply for antigen tests, but not all facilities offer them.Both lab groups stress that COVID-19 testing is important, but patients should be strategic."There's been a lot of emphasis put on testing, but testing is only one piece of the puzzle," Wroblewski said. "It gives you some information, and if you're not going to do anything with that information — whether it be targeted closures. whether it be staying home and isolating — we're not going to stop the spread of disease."As far as getting more tests, it's going to take a while. Wroblewski says it could take up to six months or more to increase production capacity significantly. Labs don't expect to see a ramp-up in supplies until early 2021. 2090
