Proof: graphene can convert sunlight to electricity

Graphene has an excellent ability to convert solar radiation into energy. Now we can see how the material works and why it has the potential to massively boost the efficiency of solar cells.

Different supernovae formed our early Solar System

The first chapter about the creation of our Solar System is now ready to be written. The cloud of molecules from which the Solar System arose consisted of several generations of stardust, say researchers after analysing a meteorite.

New photos of beautiful nebula

The Danish telescope at the La Silla Observatory in Chile has captured a striking image of the star-forming nebula NGC 6559. See the beautiful picture and some of the other pictures from the telescope here.

New centre to unravel mystery of solar energy storage

A new research centre has been given five years to develop new techniques for storing solar energy.

Peak tourist year for northern lights

This year marks the solar maximum, the peak in the 11 year cycle of solar activity and the possibility of spectacular auroral displays. And tourists keep coming.

Robots will soon replace the tractor

Drone-like helicopters and field robots that can automatically detect weeds are only a couple of years away, say researchers.

Light can reveal salmon fillet

Spectroscopic analyses may be used to reveal how fresh salmon fillet is.

Scientists reinvent light

A new method enables scientists to create large, inexpensive and flexible surfaces that can emit light in the same way as an OLED TV screen. This could result in luminous clothes, glowing wallpaper and even radiant cereal packets.

Newly discovered planetary system alters our view of planet formation

New data from NASA’s Kepler mission has revealed what was thought to be difficult: a planetary system that orbits around two stars. We need to modify our theories, says Danish astronomer.

Big Bang mission relies on Danish technology

Danish researchers will supply crucial technology for a new mission to find evidence for the Big Bang theory. The mission requires technology that can measure distances of five million kilometres with the precision of a picometre – that's 0,00000000001cm.
