Image: Hubble captures infant stars transforming a nebula

This NASA/ESA Hubble Space Telescope image presents a visually striking collection of interstellar gas and dust. Named RCW 7, the nebula is located just over 5,300 light-years from Earth in the constellation Puppis.

'Two-for-one' fission aims to improve solar cell efficiency

Singlet fission occurs when an organic molecule absorbs one photon of light, then splits that light's energy in two—a doubling effect that has the potential to improve the light-harvesting efficiency in solar cells, assuming ...

An alternative way to manipulate quantum states

Researchers at ETH Zurich have shown that quantum states of single electron spins can be controlled by currents of electrons whose spins are evenly aligned. In the future, this method could be used in electronic circuit elements.

Too young to be so cool: Lessons from three neutron stars

ESA's XMM-Newton and NASA's Chandra spacecraft have detected three young neutron stars that are unusually cold for their age. By comparing their properties to different neutron star models, scientists conclude that the oddballs' ...
