Double meteor shower will peak tonight: When and where to best see the shooting stars
Two meteor showers will peak at the same time in the early morning hours on Wednesday, a relatively uncommon astronomical occurrence caused by the Earth's orbit passing through two comets' debris trails.
The Southern Delta Aquariid and the Alpha Capricornid showers have both been active since July 18 and July 12, respectively, but will peak late Tuesday night, around midnight, and continue into the early hours of Wednesday morning.
These two showers combined could produce up to 20 to 30 meteors per hour, Nick Moskovitz, a planetary astronomer with the Lowell Observatory, estimates, according to NPR.
Here's what to know about how to prepare for this summer's double meteor shower.
What is a meteor shower?
Meteorites are falling pieces of debris from comets, asteroids or meteoroids that land on Earth every day, according to NASA. When the material starts to vaporize in Earth's atmosphere, its trail can be visible to people on Earth. This is what we call 'shooting stars.'
A meteor shower is what happens when there is a higher-than-usual number of meteors falling in a short period of time.
What to know about the Southern Delta Aquariid meteor shower
The Southern Delta Aquariid shower has been active since July 18, but its peak will be late at night on July 29 until the early morning hours on July 30, NASA reported. It will remain active until about Aug. 12 and is best seen in the Southern Hemisphere.
The meteor shower gets its name from the constellation Aquarius, which is where the shower originates, and the third brightest star in that constellation, which is the Delta Aquarii, Space.com reports.
What to know about the Alpha Capricornid meteor shower
The Alpha Capricornid shower is 'not very strong,' according to the American Meteor Society, and rarely showcases more than five meteors per hour. It has been active since July 12 and will stay active until Aug. 12.
What is notable about the Alpha Capricornid shower is that it produces bright, slow-moving fireballs during its activity, which will be visible during its peak on July 29 and July 30.
How to watch the meteor showers
No special equipment is necessary to watch the meteor showers, but NASA does recommend that viewers try to get as far away from city lights as possible and put away their phones.
'In less than 30 minutes in the dark, your eyes will adapt and you will begin to see meteors,' NASA says. 'Be patient — the show will last until dawn, so you have plenty of time to catch a glimpse.'
The best time to try to see the showers will be in the early hours on July 30, after midnight, astronomer Moskovitz told NPR. Stargazers in North America should try to find the best view of the southern part of the sky, specifically for the Southern Delta Aquariid shower, Moskovitz added.
The moon is another light source that can sometimes make it hard to see meteor showers from Earth, especially if it's fully visible. Fortunately for stargazers, the moon will be in a Waxing Crescent Phase through Thursday night this week, which means it will be about 25% full, according to Astronomy magazine, so it should not impact the showers' visibility.

SpaceX Launches Crew After NASA, Russia Space Chief Meeting
A SpaceX capsule carrying astronauts from the US, Japan and Russia launched to the International Space Station on Friday, the start of a planned six-month stay in orbit for NASA. A Falcon 9 rocket topped with the crew's Dragon capsule lifted off at 11:44 a.m. local time from the Kennedy Space Center in Florida, carrying NASA astronauts Zena Cardman and Mike Fincke, Japan Aerospace Exploration Agency 's Kimiya Yui and Roscosmos cosmonaut Oleg Platonov.

Astronauts launch to the space station after sidelined by Boeing's troubled Starliner
CAPE CANAVERAL, Fla. -- Astronauts sidelined for the past year by Boeing's Starliner trouble blasted off to the International Space Station on Friday, getting a lift from SpaceX. The U.S.-Japanese-Russian crew of four rocketed from NASA's Kennedy Space Center. They'll replace colleagues who launched to the space station in March as fill-ins for NASA's two stuck astronauts. Their SpaceX capsule should reach the orbiting lab this weekend and stay for at least six months. Zena Cardman, a biologist and polar explorer who should have launched last year, was yanked along with another NASA crewmate to make room for Starliner's star-crossed test pilots. The botched Starliner demo forced Butch Wilmore and Suni Williams to switch to SpaceX to get back from the space station more than nine months after departing on what should have been a weeklong trip. Ensuring their safe return 'meant stepping aside," Cardman said before her launch. 'Every astronaut wants to be in space. None of us want to stay on the ground, but it's not about me,' said Cardman, the flight commander. Even after launch, "things can change at the last minute, so I'll count myself very fortunate when the hatch opens' to the space station. NASA's Mike Fincke — Cardman's co-pilot — was the backup for Wilmore and Williams on Starliner, making those three still the only ones certified to fly it. Fincke and Japan's Kimiya Yui, former military officers with previous spaceflight experience, were training for Starliner's second astronaut mission. With Starliner grounded until 2026, NASA switched the two to the latest SpaceX flight. Rounding out the crew is Russia's Oleg Platonov. The former fighter pilot was pulled a few years ago from the Russian Soyuz flight lineup because of an undisclosed health issue that he said has since been resolved. On hand for the first launch attempt on Thursday, NASA's new acting administrator, Transportation Secretary Sean Duffy, met with Roscosmos director general Dmitry Bakanov, an invited guest. The two discussed future collaboration, then left town after thick clouds forced a last-minute delay. 'What we learn on these missions is what's going to get us to the moon and then from the moon to Mars, which is I think the direction that NASA has to be,' Duffy said in a NASA interview. 'There's critical real estate on the moon. We want to claim that real estate for ourselves and our partners.' To save money in light of tight budgets, NASA is looking to increase its space station stays from six months to eight months, a move already adopted by Russia's space agency. SpaceX is close to certifying its Dragon capsules for longer flights, which means the newly launched crew could be up there until April. NASA is also considering smaller crews — three astronauts launching on SpaceX instead of the typical four — to cut costs. As for Starliner, NASA is leaning toward launching the next one with cargo before flying another crew. Engineers are still investigating the thruster failures and helium leaks that bedeviled Starliner following liftoff. Time is running out as NASA looks to abandon the aging space station by 2030. An air leak on the Russian side of the station remains unresolved after years of patching. 'I am not in the least worried' about the leak, which is localized, Platonov said earlier this month.
