Tesla CEO Elon Musk has made bold claims about the company's upcoming electric pickup. Now Ford, maker of America's most popular pickup truck, is already pushing back with a demonstration of what its planned electric F-150 could be capable of doing.Ford released video of a prototype electric F-150 towing a line of freight train cars weighing, according to Ford, over 1 million pounds. The truck, driven by F-150 chief engineer Linda Zhang, pulled the train for 1,000 feet.After that was done, Ford added train cars carrying 42 F-150 pickups -- one for every year that the Ford F-series has been the bestselling truck in America -- and Zhang pulled the train again. With the trucks, the train weight rose to 1.25 million pounds, according to Ford.Ford pointed out that this was a "one-time short event demonstration," in which the prototype was "towing far beyond any production truck's published capacity." Ford has not yet announced how much the production version of the truck will be capable of towing over long distances during day-to-day use.Ford did not say what sort of battery power, electric motors or gear ratios the prototype truck was using.In a podcast interview in June, 1198

The Delta Aquariid meteor shower puts on one long summer show in July and August, but it will peak at the end of July.The meter shower began July 12 and is active until August 23. A new moon on Wednesday and Thursday will provide optimal dark skies for spotting meteors. But the peak actually began Sunday, and the best chance to see them without the moon in the way will be the first week of August.The best time to see them will be about 3 a.m. ET, but the meteor shower will also be viewable when the sky is darkest in the overnight hours until the first light of dawn.Expect to see about 20 meteors per hour during the peak, traveling at 25 miles per second.The Delta Aquariid meteors are more faint than others, and they're more apparent in the Southern Hemisphere, according to 796

The Hubble Telescope can sure find some scary images of deep space in a video released by NASA on Monday. The images were of the twin galaxies AM 2026-424, which is a mere 724 million light-years away from Earth. That means the light we are seeing on Earth was emitted 724 million years ago.From Earth, the colliding galaxies appear to form the shape of a face, with two "eyes," which make up the core of the galaxies."Each 'eye' is the bright core of a galaxy, one of which slammed into another. The outline of the face is a ring of young blue stars. Other clumps of new stars form a nose and mouth," NASA said in a statement.""Although galaxy collisions are common—especially back in the young universe—most of them are not head-on smashups, like the collision that likely created this Arp-Madore system," NASA added. "The violent encounter gives the system an arresting 'ring' structure for only a short amount of time, about 100 million years. The crash pulled and stretched the galaxies' disks of gas, dust, and stars outward. This action formed the ring of intense star formation that shapes the nose and face." 1129
