In Photos: Giant Sunspot Appears On The Sun — How To Safely See It
A giant black spot has appeared on the sun's disk — and you'll need to go find an old pair of solar eclipse glasses to safely see it with your own eyes. At over 87,000 miles (140,000 kilometers) wide, the sunspot — called AR 4079 by solar scientists who track the sun each day — is the largest of 2025 so far. Earth's diameter is 7,926 miles (12,756 kilometers). The sun only occupies half a degree of the sky, so trying to find it while wearing solar eclipse glasses is not easy. Here's how to see the sunspot: Note: it is dangerous to look at the sun through anything other than a pair of certified safe solar filters (solar eclipse glasses) bearing the ISO 12312-2 international safety standard. Don't make your own, don't use sunglasses and don't use welder's glass (sometimes the latter is safe, but only if it's Grade 13 or 14, which is hard to check). The American Astronomical Society keeps a list of Suppliers of Safe Solar Filters & Viewers. A sunspot is a magnetic disturbance on the sun's surface. Appearing on the sun's visible surface — called the photosphere — they're cooler regions on the sun caused by a concentration of magnetic field lines, according to NASA. The "AR" in a sunspot's name stands for active region because sunspots are areas of intense and complex magnetic fields and the source of solar eruptions — solar flares and coronal mass ejections. Solar flares are intense blasts of radiation that travel at light speed, while CMEs are vast clouds of charged particles that travel more slowly but are a major cause of geomagnetic storms on Earth. CMEs are frequently the root cause of displays of the northern and southern lights. In the wake of last May 10-11's displays of aurora — the most intense since 2003, according to NASA — scientists announced the arrival of the solar maximum period. However, there is a good chance of an extended period of solar activity through 2025. The number of sunspots wax and wane according to where the sun is in its solar cycle, which is, on average, 11 years long. The sun is currently at solar maximum, meaning the sunspots are bigger and more numerous than usual. AR 4079 is about half the size of the sunspot seen during the "Carrington Event" in early September 1859. The landmark solar event saw astronomer Richard C. Carrington observe the most powerful solar flare ever recorded, which later created auroras down to the tropics. The giant sunspot comes days after the world's largest solar telescope published its first spectacular image of the sun. A new instrument on the Daniel K. Inouye Solar Telescope in Haleakala, Hawaii, captures sunlight signals over a narrow range of frequencies, allowing it to map magnetic fields, solar flares and plasma at new levels of detail. Its new image revealed a cluster of sunspots covering 241 million square miles of the sun's surface. Wishing you clear skies and wide eyes.

2025 solar eclipse visible in NYC tomorow: What time, how to see it
NEW YORK - Not only is this weekend treating us with near 80-degree weather, but New Yorkers can expect another treat from the skies - a partial solar eclipse! JUMP TO: What time is the eclipse? | What will the eclipse look like? | NYC weather forecast On Saturday morning, the moon will slide in front of the sun, creating a partial solar eclipse visible across parts of the Northeast. This includes New York City, where 22% of the sun will be covered. Here's what you need to know about eclipse timing and how you can see the celestial spectacle - if the weather permits! Local perspective For the Tri-State, the timing is tricky. The eclipse will begin before sunrise, meaning the sun will already be partially covered when it rises over the city skyline. That gives you just a few minutes to catch the show before it ends. Sunrise (when the eclipse begins): 6:44 a.m. Maximum: 6:46 a.m. Eclipse ends: 7:04 a.m. According to FOX 5 NY's Mike Woods, light showers and fog could impact visibility during the partial eclipse, but it's early, and cloud cover predictions can change quickly. According to the FOX Forecast Center, almost the entire U.S. eclipse zone is forecast to be shrouded in clouds on Saturday morning. There may be a small gap of clearing in eastern Pennsylvania and New Jersey, but the eclipse won't be too noticeable there. Still, getting a lucky break in the clouds could reveal the show. The moon will block only 22% of the sun, meaning if we can see the eclipse, it will look like a wide crescent, like someone took a bite out of the sun. See the image below: Eclipse watchers should also keep an eye out for crescent sun shadows! Unlike a total solar eclipse– when the moon's shadow completely covers the sun for several minutes – a partial eclipse does not allow you to look directly at the Sun without eye protection at any time. To view a partial eclipse, you must wear your certified solar eclipse glasses for the entirety of the event. These glasses need to meet the ISO 12312-2 international standard for direct sun viewing, according to the American Astronomical Society. Regular sunglasses are not safe for viewing any partial or annular eclipse because sunglasses allow more sunlight than is safe for your eyes. A partial eclipse is also indirectly visible through the shadows you can create with your hands or other objects. The eclipse will be visible in Europe, western Africa, eastern Canada and the northeastern U.S. The timing of the event will be better for those across the Atlantic Ocean, who are hours ahead of the U.S. Other Northeast Corridor cities, including Philadelphia and Boston, will get a peek at the partial eclipse.

Can you watch the solar eclipse or film it with your phone? Here's how to do it safely
Taking out your phone and capturing an incredible, once-in-a-lifetime moment makes sense. However, when it comes to eclipses, you should take a second to check if you can record it for an Instagram Reel safely without causing lasting damage to your eyes or your smartphone camera. A partial solar eclipse is set to be visible to parts of the United States is set to begin a little before sunrise on Saturday, March 29, 2025, according to NASA. "The eclipse is more than half over at sunrise in New England but lasts long enough for observers there to catch at least a few minutes of the event," NASA said. "This is a partial eclipse everywhere in the shadow path. The central umbra shadow misses the Earth." The partial solar eclipse is set to end a little after 7 a.m. Here's what you need to know about capturing a moment of Saturday's partial solar eclipse. In Worcester, the eclipse will start before sunrise and last until 7:08 a.m., according to Date and Time, on Saturday March 29. Currently, the forecast is calling for overcast skies and rain on the morning of the eclipse, which could hinder viewing. According to NASA, an unprotected phone's sensor could be damaged, just like any other image sensor, if pointed directly at the sun. A NASA post on X, formerly Twitter, said a best practice would be to hold a pair of eclipse glasses in front of the phone's lens when photographing the sun at any point during the eclipse. Here are some tips by NASA for taking pictures of a total solar eclipse. To take images when the sun is partially eclipsed, you'll need to use a special solar filter to protect your camera. If you don't have a telephoto zoom lens, focus on taking landscape shots and capture the changing environment. Using a tripod can help you stabilize the camera and avoid taking blurry images when there is low lighting. Additionally, using a delayed shutter release timer will allow you to snap shots without jiggling the camera. Anywhere you can point your camera can yield exceptional imagery, so be sure to compose some wide-angle photos that can capture your eclipse experience. NASA photographer Bill Ingalls recommends focusing on the human experience of watching the eclipse. 'The real pictures are going to be of the people around you pointing, gawking, and watching it,' Ingalls noted. 'Those are going to be some great moments to capture to show the emotion of the whole thing.' To avoid any damage to your smartphone camera, you will need to purchase an ISO-certified filter, ISO 12312-2. You should never directly look at a solar eclipse, partial or otherwise, without proper eye protection. Solar eclipse eye protection: Reminder: You need eclipse glasses to look at the partial eclipse. Where to get them Additionally, while it's not recommended to directly observe a solar eclipse through your phone's camera or screen without proper filters or equipment, you can certainly use your phone to indirectly view or capture the eclipse safely. To ensure safety, make sure you're wearing your solar eclipse glasses while witnessing the solar eclipse. Jennifer Dixon contributed to the reporting of this story.

How to Watch the Partial Solar Eclipse This Weekend
Eclipse season is not over yet! Sky gazers will be able to catch a glimpse of the upcoming partial solar eclipse on March 29 — the second eclipse of the month. Unlike a total solar eclipse, where the moon fully covers the sun, the moon will only cover a portion of the sun during a partial solar eclipse. Per NASA, this occurs because the moon, sun and Earth are not in perfect alignment, which results in a partial eclipse. Eclipse energy is known to bring a lot of changes in a person's life in astrology, and this solar eclipse will be no different, especially since the collective is fresh off the heels of a total lunar eclipse that took place on March 14. "The solar eclipse will bring a surge of excitement and passion to our lives," celebrity astrologer Kyle Thomas tells PEOPLE exclusively, noting that we will feel its effects in the weeks before and after its peak. "We will be inspired to take the leap and move in a new direction," he adds. Many of the characteristics used to describe Aries will be reflected within us during this time. "Its energy is bold, passionate and adventurous, allowing us to assert our egos and pursue our innermost desires," says Thomas. "Envision what you'd like to tackle in the year to come!" Here's everything to know about the partial solar eclipse, including where to get the best view and how to watch it. The partial solar eclipse will take place on March 29, 2025. Per NASA, the partial solar eclipse will be visible in parts of Europe, Asia, Africa, North America, South America, the Atlantic and Arctic Oceans. According to some parts of Canada, the United States and Greenland will get the best views of the eclipse. Viewing times for the partial solar eclipse depend on where you're located in the world. For those in the U.S., the eclipse will begin at 6:13 a.m. EDT and will last about an hour before ending at 7:17 a.m. EDT, per Like previous solar eclipses, it's not safe to look at the sun without proper eye protection except during the brief total phase during a total solar eclipse. NASA recommends "specialized eye protection for solar viewing" through eclipse glasses or a handheld solar viewer during the eclipse. Unlike regular glasses, "safe solar viewers are thousands of times darker and ought to comply with the ISO 12312-2 international standard." If there are any tears or scratches on the eclipse glasses, you must discard them and use a pair that is not damaged. It is also recommended not to view the eclipse through "a camera lens, telescope, binoculars, or any other optical device while wearing eclipse glasses or using a handheld solar viewer" since "the concentrated solar rays will burn through the filter and cause serious eye injury." If you don't have eclipse glasses handy, you can also use indirect viewing methods to watch the eclipse. The next partial solar eclipse will take place on Sept. 21, 2025, and will be visible in Australia, Antarctica, the Pacific and Atlantic Oceans. Meanwhile, skygazers will have to wait until August 2026 for the next total solar eclipse. Read the original article on People

Partial solar eclipse to be visible in NYC this weekend
NEW YORK (PIX11) — Get your eclipse glasses ready for a show in the sky this weekend. The moon will pass between the sun and the Earth for a partial solar eclipse on Saturday morning, according to NASA. New Yorkers will be able to see the eclipse starting at 6:44 a.m. with maximum coverage at 6:46 a.m., as laid out on the Space Administration's website. Things To Do Around NYC About 22% of coverage over the sun will be visible to those in the five boroughs. Visibility of the partial eclipse will end around 7:04 a.m. in NYC. Only cities in Greenland and Canada will see more than 80% of eclipse coverage. Much like last year's solar eclipse, astronomers warn residents to wear viewing glasses known as 'eclipse glasses' that comply with the ISO 12312-2 international standard. More Local News Additionally, residents are advised not to look at the eclipse through a camera lens, telescope, binoculars, or any other optical device while wearing eclipse glasses. The concentrated solar rays can burn through the filter and cause serious eye injury, astronomers at NASA say. This marks the second eclipse for March after the duel lunar eclipse and blood moon was visible on March 14. A second partial solar eclipse is expected on Sept. 21, however, it will likely only be visible in Australia, the Pacific, the Atlantic, and Antarctica.
