Instead of just trying to slap solar panels to an existing plane, an airframe should ideally be designed from the ground up as a balancing act between a range of factors. These include weight ...

A team of scientists has unveiled the existence of an interstellar tunnel near our solar system, which could be a gateway to other stars.

The solar system drifts inside an immense, low-density cavity known as the Local Hot Bubble (LHB). This region, spanning at least 1,000 light-years, radiates X-rays due to its searing million-degree ...

"We were quite surprised," Dones continued. "Spirals are seen in Saturn's rings, disks around young stars and galaxies. The ...

We’ve previously covered solar plane entered into the Hackaday prize as well as an actual seafaring solar powered unmanned sail boat that crossed the North Atlantic.

The solar-powered plane was a technological feat in 2015, but wasn't scalable, said Climate Impulse engineer and co-pilot Raphael Dinelli. Limited in range, that plane had to make more than a ...

One of the plane's solar panels is visible on the left side of the photo, while what appears to be its open payload bay is visible along the top edge. The vehicle has been in orbit for well over a ...

Once again, the Solar Orbiter has flown close to Venus. This time, however, the probe was deflected in such a way that it is now leaving the orbital plane. After a particularly close flyby of ...
