X-57 Electric Plane (nicknamed Maxwell). NASA has announced an experimental electric airplane called the X-57, which could reduce flight times and carbon emissions for passenger planes in the future. The plane, which will test the space agency’s new propulsion technology, is nicknamed after James Clerk Maxwell, the 19th century Scottish physicist who worked in the field of electromagnetism. The space agency’s Scalable Convergent Electric Propulsion Technology Operations Research project plans to build the plane by modifying the existing Italian-designed Tecnam P2006T twin-engine light aircraft. The X-57 will use a long skinny wing embedded with 14 electric motors. Twelve of the motors will be positioned on the leading edge of the plane for take offs and landings, while the larger motor on each wing tip will be used while at cruise altitude. It will be powered only by batteries, eliminating carbon emissions altogether. NASA hopes to demonstrate that X-57 technology could benefit travellers by reducing journey times, aircraft noise and fuel usage, as well as reducing operational costs for small airplanes by as much as 40%. While fuel-powered planes typically need to fly slower in order to get the best fuel efficiency, electric propulsion could help to tackle this problem, according to the space agency. X-57 is part of NASA’s decade-long New Aviation Horizons initiative, which will see it develop as many as five larger X-Planes with the aim of eventually producing them commercially.

Anticrepuscular rays are spectacular optical phenomena that are quite rare and they require the viewer to have his or her back to the sun or sunset point. They are columns of sunlit air streaming through gaps in clouds. Yet while the former seem to converge from the sun, anticrepuscular rays converge toward the antisolar point, the point in the sky directly opposite the sun, creating some stunning effects. (Source)
Well-preserved remains of a 12,400-year-old puppy from the extinct Pleistocene canid species have been discovered near the Tumat village in the Sakha Republic of Russia. Scientists believe the puppy was an ancient pet — one of man’s first best friends. How they plan to bring the animal back to life.
