How to catch the Geminids, one of the strongest meteor showers of the year

The Geminids — among the few major meteor showers to come from asteroids — peak on Friday. It's one of the year's last chances to see fireballs in the sky.

The shower often produces meteors with a distinctly more yellow glow, likely due to the unusual origin material, said Sally Brummel, planetarium manager at the University of Minnesota’s Bell Museum.

Under ideal viewing conditions, the Geminids typically put on one of the best and brightest shows of the year because of the high volume of meteors visible each hour. However, an almost full moon this year means up to 15 meteors per hour are expected at peak time, according to the American Meteor Society.

The moonlight “will wash out a lot of them," Brummel said.

Viewing lasts until Dec. 21. Here’s what to know about the Geminids and other meteor showers.

Multiple meteor showers occur annually and you don’t need special equipment to see them.

Most meteor showers originate from the debris of comets, but a few — including the Geminids — result from the debris of asteroids. The Geminids come from the sun-orbiting asteroid 3200 Phaethon.

When rocks from space enter Earth’s atmosphere, the resistance from the air makes them very hot. This causes the air to glow around them and briefly leaves a fiery tail behind them — the end of a “shooting star.”

The glowing pockets of air around fast-moving space rocks, ranging from the size of a dust particle to a boulder, may be visible in the night sky.

The rocky nature of asteroid debris makes the Geminids especially likely to produce fireballs, said NASA's William Cooke. “Those are pretty tough rocks that can penetrate deep into the atmosphere,” he said.

Meteor showers are usually most visible between midnight and predawn hours.

It’s easier to see shooting stars under dark skies, away from city lights. Meteor showers also appear brightest on cloudless nights when the moon wanes smallest.

And your eyes will better adapted to seeing meteors if you aren’t checking your phone.

The next meteor shower, the Ursids, will peak on Dec. 22.

A federal appeals court on Friday left in place a mid-January deadline in a federal law requiring TikTok to be sold or face a ban in the United States, rejecting a request made by the company to halt enforcement until the Supreme Court reviews its challenge of the statute.

Attorneys for TikTok and its China-based parent company, ByteDance, are expected to appeal to the Supreme Court.

It’s unclear if the nation's highest court will take up the case, though some legal experts have said they expect the justices to weigh in due to the types of novel questions it raises about social media, national security and the First Amendment. TikTok is also looking for a potential lifeline from President-elect Donald Trump, who promised to “save” the short-form video platform during the presidential campaign.

Attorneys for TikTok and ByteDance had requested the injunction after a panel of three judges on the U.S. Court of Appeals for the District of Columbia Circuit sided with the U.S. government and rejected their challenge to the law.

The statute, which was signed by President Joe Biden earlier this year, requires ByteDance to sell TikTok to an approved buyer due to national security concerns or face a ban in the U.S.

The U.S. has said it sees TikTok as a national security risk because ByteDance could be coerced by Chinese authorities to hand over U.S. user data or manipulate content on the platform for Beijing’s interests. TikTok has denied those claims and has argued that the government’s case rests on hypothetical future risks instead of proven facts.

In the request filed last week, attorneys for TikTok and ByteDance had asked for a “modest delay” in enforcement of the law so that the Supreme Court could review the case and the incoming Trump administration could “determine its position” on the matter.

If the law is not overturned, the two companies have said that the popular app will shut down by Jan. 19, just a day before Trump takes office again. More than 170 million American users would be affected, the companies have said.

The Justice Department had opposed TikTok’s request for a pause, saying in a court filing last week that the parties had already proposed a schedule that was “designed for the precise purpose” of allowing Supreme Court review of the law before it took effect.

The appeals court issued its Dec. 6 ruling on the matter in line with that schedule, the Justice Department filing said.
