Researchers develop method of fabricating perovskite solar cells that is more efficient, costs less
A solar eclipse sheds light on physics
On 29 May 1919, a shadow dance took place over the Caribbean which was to make history: While the new moon covered the blazingly bright disk of the Sun, astronomers around Arthur Stanley Eddington measured ...
Fine-tuned molecular orientation is key to more efficient solar cells
Polymer solar cells are a hot area of research due to both their strong future potential and the significant challenges they pose. It is believed that thanks to lower production costs, they could become a ...
Using a sounding rocket to help calibrate NASA's SDO
Watching the sun is dangerous work for a telescope. Solar instruments in space naturally degrade over time, bombarded by a constant stream of solar particles that can cause a film of material to adhere to ...
Pacific quest: Solar pilot prepares for toughest leg
Strapped into a seat in a tiny one-man cabin, Swiss pilot Andre Borschberg will have to endure extraordinary conditions as he flies over the Pacific Ocean for five days and nights, powered only by the sun.
Toughest leg of Solar Impulse's global journey delayed
The most challenging leg of Solar Impulse 2's landmark flight around the world powered only by the sun was delayed on Tuesday due to concerns about the weather, organisers said.
How long will our spacecraft survive?
There are many hazards out there, eager to disrupt and dismantle the mighty machines we send out into space. How long can they survive to perform their important missions?
Image: Coronal loops over a sunspot group
The Atmospheric Imaging Assembly (AIA) instrument aboard NASA's Solar Dynamics Observatory (SDO) images the solar atmosphere in multiple wavelengths to link changes in the surface to interior changes. Its ...
How bad can solar storms get?
Our sun regularly pelts the Earth with all kinds of radiation and charged particles. How bad can these solar storms get?
Carbon nanotubes and inorganic nanoparticles enhance photosynthetic activity and stability
A new process has been developed for spontaneously incorporating and assembling carbon nanotubes (CNTs) and oxygen scavenging nanoparticles into chloroplasts, the part of plant cells that conduct photosynthesis ...
Engineering mechanical parts for space activity
For more than four decades, an unremarkable building in an industrial estate on the edge of Warrington, UK, has played a crucial role in the success of most European space missions with moving parts – which ...
Fire at giant Apple plant in Arizona quickly controlled
A fire at a huge plant owned by tech giant Apple Inc. in the Phoenix suburb of Mesa caused a section of the roof to collapse, but no one was hurt.
