The Perseid meteor shower is peaking Tuesday. Here's how to see it
The Perseid meteor shower, which is known for producing dozens of bright meteors that leave long streaks in their wake, is set to peak at 4 p.m. ET Tuesday.
In previous years, it produced around 40 to 50 visible meteors per hour, but sky-gazers likely won't see as many this year, said Bill Cooke, the lead for NASA's Meteoroid Environments Office. This is due to the fact that the Perseid shower is occurring shortly after August's full moon.
The moon will be in a waning gibbous phase and at around 85% illumination, which means the light from the moon will make meteor-spotting more difficult. According to experts, you may see around 10 to 20 meteors per hour.
While the peak of the Perseids will happen well before sunset in the US, there are two windows of time between Tuesday night and Wednesday morning during which stargazers should aim to be outside for the best chance of glimpsing a meteor.
'Between dusk and moonrise on the evening of August 12, there's going to be a one-hour gap before the moon rises,' when you can look for Perseid activity, said Robert Lunsford, fireball report coordinator for the American Meteor Society.
These meteors shoot out in all directions from the constellation Perseus, which is located in the northern sky. Lunsford noted, however, that, due to Perseus appearing low on the horizon at this time, much of the meteor activity will be blocked from view.
'Any meteors you do see at that time are going to be called Earth grazers because they can just graze the upper atmosphere,' he said. While most Perseid meteors are visible for mere milliseconds, the few earth grazers you might spot 'will be very long and will last two or three seconds,' he added.
The last couple of hours before daybreak on Wednesday is the other window during which Lunsford recommends trying to see the shower. 'There'll be a bright moon up in the southern sky, but if you turn your gaze northward and look kind of toward the constellation Perseus, you can still see the brighter meteors.'
The peak of the Perseids is occurring just after the conjunction of Venus and Jupiter, and the two planets will still be close together and shining brightly. The best views will be in the eastern sky before sunrise.
'These are the two brightest planets,' Lunsford said. 'This (conjunction) happens about once a year, but it's still spectacular when you get the two brightest planets really close to each other.'
Saturn will also be joining the night's celestial display in the late evening hours on Tuesday. It will appear near the moon and will rise before midnight, according to EarthSky.
Here are the peak dates of other meteor showers anticipated in 2025, according to the American Meteor Society and EarthSky.
Draconids: October 8-9
Orionids: October 22-23
Southern Taurids: November 3-4
Northern Taurids: November 8-9
Leonids: November 16-17
Geminids: December 13-14
Ursids: December 21-22
Look out for four more full moons this year, with supermoons occurring in October, November and December. Their dates are:
September 7
October 6
November 5
December 4
Two eclipse events will take place as summer draws to a close.
A total lunar eclipse will be visible in Europe, Asia, Australia, Africa, parts of eastern South America, Alaska and Antarctica on September 7 and 8, according to Time and Date.
A lunar eclipse occurs when the moon passes directly into Earth's shadow as the sun, Earth and the moon line up. This causes the moon to appear darker or dimmed.
When the moon sits in the darkest part of Earth's shadow, the sun's rays peek out from behind Earth and the light refracts, giving the moon a reddish hue, according to London's Natural History Museum. Some people call the result a 'blood moon.'
Two weeks later, on September 21, a partial solar eclipse will be visible in parts of Australia, the Atlantic, the Pacific and Antarctica.
Solar eclipses occur when the moon moves between the sun and Earth. In the case of a partial solar eclipse, the moon does not fully block out the sun. It creates a crescent — as if the moon took a bite out of the sun.

Perseids Meteor Shower Live Tracker: Peak Time, Locations to See Shower Tonight
One of the most anticipated celestial events of the year is set to dazzle skywatchers as the Perseid meteor shower reaches its peak on the night of August 12 into the early hours of August 13. Known for producing bright fireballs and up to 100 meteors per hour under ideal conditions, the Perseids offer a stunning display — even with moonlight interference — and can be viewed live online or outdoors with the naked eye. What to Know: The Perseid meteor shower peaks overnight August 12–13, with best viewing between 2 a.m. and 4 a.m. local time. The Virtual Telescope Project will host a free livestream starting at 5 p.m. EDT on August 12, featuring real-time views and expert commentary. The shower originates from debris left by Comet Swift-Tuttle and appears to radiate from the constellation Perseus in the northeastern sky. A waning gibbous moon, 86% illuminated, may obscure fainter meteors, but bright fireballs should still be visible. No equipment is needed — just a dark sky location, patience, and time for your eyes to adjust. The Perseids are active from July 17 to August 23, but the peak nights offer the most dramatic views.

Autism diagnoses occurring earlier for boys, girls often wait years, analysis finds
Autism is being diagnosed earlier in young children, especially in boys, according to a major new analysis of medical records published on Tuesday. Conducted by Epic Research -- the data and analytics arm of the electronic health record software company, Epic Systems -- the analysis also found that many girls still face years-long delays in receiving a diagnosis and an increasing share of women are not diagnosed until adulthood. This raises concerns about missed opportunities for early support, Dr. Catherine Lord, the George Tarjan Distinguished Professor of Psychiatry and Education in the David Geffen School of Medicine at UCLA, told ABC News. MORE: RFK Jr. lays out new studies on autism, shuts down 'better diagnoses' as a cause "There is evidence that girls are often diagnosed later than boys, and particularly girls with milder symptoms are missed entirely," Lord, who was not involved in the analysis, said. "When you add in adults seeking a diagnosis later in life -- often more women than men -- it pushes the average age of diagnosis for females even higher." The study reviewed records from more than 338,000 patients who received their first autism spectrum disorder diagnosis between 2015 and 2024, using aggregated electronic health record data from hospitals and clinics nationwide to study health care trends. While not peer-reviewed, Epic Research's work is vetted internally by the company's clinical and research experts. The median age at diagnosis for all children fell from age 7 in 2015 to age 6 in 2024, the analysis suggested. For boys, the median age dropped from age 7 to age 5, with nearly half diagnosed before age 5 in 2024. Girls showed no similar shift, the analysis found. Their median age of diagnosis remained at about age 8, and only about one-third were diagnosed before age 5. The disparity persisted into adulthood, with one in four women first diagnosed at age 19 or older, compared with about one in eight men, the analysis found. Although the median age for diagnosis dropped, the average age remained at about 10.5 years old, likely implying that some people were being diagnosed much later, potentially into adulthood. Early detection matters because therapies, school accommodations, and interventions -- often involving speech-language pathologists, occupational therapists and developmental pediatricians -- are most effective when started early in life, Lord explained. "The biggest time of change particularly in developing language, is in the early years," Lord said. "Interventions can speed up learning and help prevent later anxiety and depression by making life easier for autistic kids and their families." MORE: RFK Jr.'s comments on autism draw reactions from parents and experts Early signs of autism can include limited eye contact, not responding to their name, delayed speech, repetitive behaviors such as hand-flapping or lining up objects, intense or unusual interests, and distress over changes in routine, according to the Centers for Disease Control and Prevention (CDC) , In girls, these signs may be harder to notice or focused on socially typical topics, which can delay recognition. For families facing barriers to diagnosis, Lord recommended seeking evaluations through schools, contacting state-run early intervention programs for children under age three. She also recommended relying on credible sources such as the CDC, Autism Speaks and the Autism Science Foundation for more information. "There's much more hope now for autism," she said. "Not to 'cure' it, but to support people, figure out their strengths, and help them find their place in the world." Christian S.

Here's How to Spot Bright Fireballs During the Dazzling Perseids Meteor Shower
Skygazers rejoice, the summer isn't finished with delivering dazzling meteor showers. The last week of July saw dueling meteor showers taking over the sky, but the most popular meteor shower of the year won't hit its peak until next week. The Perseids meteor shower is about to give you a real light show, provided you're far enough away from light pollution to see it. Perseids are known for their bright fireballs and plentiful meteors. The show started on July 17, and will run through Aug. 23. The reason the Perseids meteor shower is so popular is twofold. First, it takes place in the summer, so going outside and watching it is less uncomfortable than other large meteor showers like Quadrantids, which takes place in wintery January. The other reason is that it's one of the most active meteor showers of the year. During its peak, the meteor shower is known to rain down as many as 100 meteors per hour, according to the American Meteor Society. These not only include your typical shooting stars, but also a higher chance for fireballs, which are meteors that explode as they enter orbit. Per NASA, fireballs tend to last longer than standard shooting stars and can come in a variety of different colors. Perseids come to Earth courtesy of the 109P/Swift-Tuttle comet. Earth's orbit around the sun brings it through Swift-Tuttle's tail every year. The comet itself takes 133 years to orbit the sun. Its last perihelion -- the point at which it's the closest to the sun -- was in 1992. It won't be back until the year 2125. Until then, it leaves behind an excellent tail of dust and debris to feed us yearly meteor showers. How to catch the Perseids meteor shower The best time to view the Perseids is during its peak, which occurs on the evenings of Aug. 12 and 13. During this time, the shower will produce anywhere from 25 to 100 meteors per hour on average. However, since the shower officially lasts for over a month, you have a chance to see a shooting star on any given evening, provided that you're far enough away from light pollution. Thus, if you're planning on watching this year's Perseids during their peak, you'll want to get out of the city and suburbs as far as possible. According to Bill Cooke, lead of NASA's Meteoroid Environments Office, folks in the city might see one or two meteors from the meteor shower per hour, which is pocket change compared to what those outside city limits might see. Regardless, once you've arrived at wherever you want to watch the meteors, you'll want to direct your attention to the radiant, or the point at which the meteors will appear to originate. Like all meteors, Perseids are named after the constellation from which they appear. In this case, it's Perseus. Per Stellarium's free sky map, Perseus will rise from the northeastern horizon across the continental US on the evenings of Aug. 12 and 13. It'll then rise into the eastern sky, where it'll remain until after sunrise. So, in short, point yourself due east and you should be OK. Binoculars may help, but we recommend against telescopes since they'll restrict your view of the sky to a very small portion, which may hinder your meteor-sighting efforts. The American Meteor Society also notes that the moon may give viewers some difficulty. Perseids' peak occurs just three days after August's full moon, so the moon will still be mostly full. Thus, it is highly probable that light pollution from the moon may reduce the number of visible meteors by a hefty margin, depending on how things go.
