ALPHA observes light spectrum of antimatter for first time

In a paper published today in the journal Nature, the ALPHA collaboration reports the first ever measurement on the optical spectrum of an antimatter atom. This achievement features technological developments that open up ...

Earth always has a second temporary moon, researchers claim

In the fall of 2006, observers at the Catalina Sky Survey in Arizona found an object orbiting the Earth. At first, it looked like a spent rocket stage -- it had a spectrum similar to the titanium white paint NASA uses on ...

The human eye can see 'invisible' infrared light

World record solar cell with 44.7% efficiency

German Fraunhofer Institute for Solar Energy Systems, Soitec, CEA-Leti and the Helmholtz Center Berlin announced today that they have achieved a new world record for the conversion of sunlight into electricity using a new ...

Mysterious objects at the edge of the electromagnetic spectrum

The human eye is crucial to astronomy. Without the ability to see, the luminous universe of stars, planets and galaxies would be closed to us, unknown forever. Nevertheless, astronomers cannot shake their fascination with ...

Team obtains the best measurement of neutron star size to date

An international research team led by members of the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI) has obtained new measurements of how big neutron stars are. To do so, they combined a general ...
