Oh, joy.

Astrophysicists have discovered a stellar “superflare” on a star observed by NASA’s Kepler space telescope with wave patterns similar to those that have been observed in the Sun’s solar flares. (Superflares are flares that are thousands of times more powerful than those ever recorded on the Sun, and are frequently observed on some stars.)

The scientists found the evidence in the star KIC9655129 in the Milky Way. They suggest there are similarities between the superflare on KIC9655129 and the Sun’s solar flares, so the underlying physics of the flares might be the same.

Following two failed landings at sea, the next Falcon 9 rocket will attempt to touch down at Cape Canaveral.

After SpaceX’s Falcon 9 rocket returns to flight later this month, the company will try to land the first stage booster back on solid ground, according to NASA officials. If successful, it would mark not only the first successful landing and recovery of the company’s flagship rocket, but also the first terrestrial rocket landing for SpaceX after two failed landing attempts at sea.

The launch—which could come as soon as December 15, though a flight plan has not been confirmed by the U.S. Air Force—marks a big next step for SpaceX. The mission will be the company’s first since a June launch in which an unmanned Falcon 9 bound for the International Space Station broke apart mid-flight. The landing attempt will also follow the successful launch and landing of a reusable rocket by rival spaceflight company Blue Origin last week.

Researchers at Linköping University’s Laboratory of Organic Electronics, Sweden, have developed power paper — a new material with an outstanding ability to store energy. The material consists of nanocellulose and a conductive polymer. The results have been published in Advanced Science.

One sheet, 15 centimetres in diameter and a few tenths of a millimetre thick can store as much as 1 F, which is similar to the supercapacitors currently on the market. The material can be recharged hundreds of times and each charge only takes a few seconds.

It’s a dream product in a world where the increased use of renewable energy requires new methods for energy storage — from summer to winter, from a windy day to a calm one, from a sunny day to one with heavy cloud cover.
