Time passes slowly deep into a gravitational field. Gravity i reduced if you move further into the Earth, but nevertheless the core of the Earth is 2.5 years younger than the crust. (Ill: NASA)

Earth as a 'time machine' is more efficient than calculated by Feynman

2016.04.21The core of the Earth is years younger than the surface. We knew that from Einsteins general theory of relativity, but a thorough recalculation shows that the original value calculated by Richard Feynman i 1962 needs correction. Instead of a few days, the difference amounts to 2,5 years. Ulrik Uggerhøj from IFA and collaborators show this in a new paper.

Are humans the new supercomputer?

2016.04.14Today, people of all backgrounds can contribute to solving serious scientific problems by playing computer games. A research group from IFA has extended the limits of quantum physics calculations. The results of game based research was published in Nature 14 April 2016.

This is how it is being a planet too close to it's star. The atmosphere will boil away from the plaent and into space. Drawing: Peter Devine.

Don't come too close to the stars if you are a super-Earth

2016.04.11Coming too close to the fire will get your fingers burnt. This old adage is also valid for exoplanets orbiting remote stars. Mia S. Lundkvist and a group of astronomers, of which many are affiliated with the Stellar Astrophysics Centre at Aarhus University, Denmark, have shown that it is also true in the real world. In the newly published paper titled "Hot super-Earths stripped by their host stars" in Nature Communications the researchers explain their methods and results.

The sugar of life found on comet 67/P

2016.04.11The fundamental building blocks of life seem to be 'easily' found in the Universe. Thanks to data transmitted from the comet lander Philae during it's short active period on comet 67/P, researchers from Aarhus University have participated in finding results that may change our fundamental understanding of the origin of life on Earth.(Article in Danish).
