Closest image of sun by "Solar Orbiter" ( till now).

"The Solar Orbiter",which was launched on 10 February,2020 by European Space Agency and NASA took the closest ever image of sun. The most detailed images of sun ever.

These images reveals a unique phenomena of sun called "Campfires"."Campfires" are actually tiny solar flares. The image of campfire was taken by an Extreme Ultraviolet Imager (EUI) of Solar Orbiter. The space craft was nearly at the middle of sun and earth (77 million km from sun).

Exceptionally well detailed image of sunspot captured from world largest solar observatory.

This high resolution (till now) image of sun showing a spot was captured by the U.S National Science Foundation's Daniel K. Ynouye Solar Telescope. According to Dr. Thomas Rimmele, Associate Director at National Solar Observatory " The sunspot image achieves a spatial resolution about 2.5 times higher than ever previously achieved, showing magnetic structures as small as 20 kilometres on the surface of the sun".

The sunspot is spread across 10000 miles was taken on 28 January,2020. The spot is just a tiny fraction of the sun yet a planet like earth would fit perfectly. For more detail: Click here

Single device that can collect energy from sun and outer space simultaneously.

Courtesy:Linda Cicero, Stanford News Stanford scientists has demonstrated for the first time that heat from the sun and coldness from outer space can be collected simultaneously. The above image shows the apparatus,a double-layered rooftop panel.The top layer uses the standard semiconductor materials that go into energy-harvesting solar cells, the novel materials on the bottom layer perform the cooling task.
