There’s also the possibility of seeing 10 to 12 meteors that aren’t associated with any of these showers, according to Lunsford. kraken36 https://kra--36---cc.ru Both the Alpha Capricornids and Southern Delta Aquariids become visible annually when Earth passes through debris fields left by two Jupiter-family comets: 169P/NEAT (Alpha Capricornids) and P2008/Y12 (Southern Delta Aquariids). Cook also noted that, each year, “we’re passing closer to the core of the material that produces (the Alpha Capricornids) shower and in 200 years, it’ll be the strongest shower that’s visible from Earth. It’ll actually produce more than 1,000 (meteor streaks) an hour, which is quite a bit stronger than it is now.” For those interested in contributing to astronomers’ understanding of meteors, this week presents the perfect opportunity to count how many meteors you see in the night sky and report them to places like the American Meteor Society. Upcoming Meteor Showers Here are the other meteor showers to anticipate in 2025 and their peak dates, according to the American Meteor Society and EarthSky. Perseids: August 12-13 Draconids: October 8-9 Orionids: October 22-23 Southern Taurids: November 3-4 Northern Taurids: November 8-9 Leonids: November 16-17 Geminids: December 12-13 Ursids: December 21-22 Related article Lunar and solar eclipses in 2025 Two eclipse events will occur as summer ends. 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 Earth passes exactly between the sun and the moon, throwing the latter into shadow and making it appear darker or dimmed. When the moon sits in the darkest part of Earth’s shadow, the sun’s rays bend around Earth and refract light on the moon’s surface, which gives it a reddish hue, according to London’s Natural History Museum. Some people call the result a “blood moon.” Two weeks after the total lunar eclipse, a partial solar eclipse will be visible in parts of Australia, the Atlantic, the Pacific and Antarctica on September 21. Solar eclipses occur when the moon moves between the sun and Earth, blocking part of the sun’s surface from view, according to NASA. This creates a crescent shape — as if something took a “bite” out of the sun.

• 02/08/2025 - 12:57 Гость It all started back in March, when dozens of surfers at beaches outside Gulf St Vincent, about an hour south of state capital Adelaide, reported experiencing a sore throat, dry cough and blurred vision after emerging from the sea. a href=https://trip-scan.org tripskan /a Shortly after, a mysterious yellow foam appeared in the surf. Then, dead marine animals started washing up. Scientists at the University of Technology Sydney soon confirmed the culprit: a buildup of a tiny planktonic algae called Karenia mikimotoi. And it was spreading. https://trip-scan.org трипскан In early May, the government of Kangaroo Island, a popular eco-tourism destination, said the algal bloom had reached its coastline. A storm at the end of May pushed the algae down the coast into the Coorong lagoon. By July, it had reached the beaches of Adelaide. Diverse algae are essential to healthy marine ecosystems, converting carbon dioxide into oxygen and benefiting organisms all the way up the food chain, from sea sponges and crabs to whales. But too much of one specific type of algae can be toxic, causing a harmful algal bloom, also sometimes known as a red tide. While Karenia mikimotoi does not cause long-term harm to humans, it can damage the gills of fish and shellfish, preventing them from breathing. Algal blooms can also cause discoloration in the water and block sunlight from coming in, harming ecosystems. The Great Southern Reef is a haven for “really unique” biodiversity, said Bennett, a researcher at the University of Tasmania, who coined the name for the interconnected reef system which spans Australia’s south coast. About 70% of the species that live there are endemic to the area, he said, meaning they are found nowhere else in the world. “For these species, once they’re gone, they’re gone.”
