Comet likely last seen when Neanderthals walked Earth could soon dazzle in the night sky [url=https://e-stock.by/product/chekhol-dlya-telefona-spigen-ultra-hybrid-zero-one-magfit-dlya-iphone-15-pro-acs07216-ser-11/]Чехол для телефона Spigen Ultra Hybrid Zero One (MagFit) для iPhone 15 Pro ACS07216 (серый/разноцветный) купить в Бресте[/url] A recently discovered comet, known as C/2023 A3 Tsuchinshan–ATLAS, will make its closest approach of Earth on Saturday. Sky-gazers won’t want to miss the event since it may be the last time the comet will be seen in the night sky for another 80,000 years. The comet successfully reached perihelion, its closest point to the sun in its orbital path around the parent star, on September 27, and was visible for those in the Southern Hemisphere in September and early October. Now, the icy body is on its way out of the inner solar system and will be visible to those in the Northern Hemisphere in mid-October through early November, according to NASA. On Saturday, the comet will come within about 44 million miles (nearly 71 million kilometers) of Earth. The comet is making its first documented flyby of our planet, according to NASA. With its 80,000-year orbit, the celestial body would have been last seen from Earth at the time of the Neanderthals. Those looking to catch a glimpse of the once-in-a-lifetime event will want to look in the western part of the night sky, shortly after sunset, according to EarthSky. The comet will look like a bright fireball in the dark sky with a long, extended tail. Bill Cooke, lead of NASA’s Meteoroid Environment Office at the Marshall Space Flight Center in Huntsville, Alabama, recommends a pair of binoculars for enhanced viewing of the comet. “It’s not going to zing across the sky like a meteor. It will just appear to hang there, and it will slowly change position from night to night,” Cooke said. “If you can see (the comet) with your unaided eye, (using) the binoculars will knock your socks off.”

Automatic takeoffs are coming for passenger jets and they’re going to redraw the map of the sky [url=https://krmp9.cc]kra10.cc[/url] In late 1965, at what’s now London Heathrow airport, a commercial flight coming from Paris made history by being the first to land automatically. The plane – A Trident 1C operated by BEA, which would later become British Airways – was equipped with a newly developed extension of the autopilot (a system to help guide the plane’s path without manual control) known as “autoland.” Today, automatic landing systems are installed on most commercial aircraft and improve the safety of landings in difficult weather or poor visibility. Now, nearly 60 years later, the world’s third largest aircraft manufacturer, Brazil’s Embraer, is introducing a similar technology, but for takeoffs. Called “E2 Enhanced Take Off System,” after the family of aircraft it’s designed for, the technology would not only improve safety by reducing pilot workload, but it would also improve range and takeoff weight, allowing the planes that use it to travel farther, according to Embraer. “The system is better than the pilots,” says Patrice London, principal performance engineer at Embraer, who has worked on the project for over a decade. ”That’s because it performs in the same way all the time. If you do 1,000 takeoffs, you will get 1,000 of exactly the same takeoff.” Embraer, London adds, has already started flight testing, with the aim to get it approved by aviation authorities in 2025, before introducing it from select airports.
