Successful launch of LISA Path-finder
Successful launch of LISA Path-finder
After the successful lift-off of the Vega rocket in French Guiana, the LISA Pathfinder satellite uncoupled from its booster rocket at approximately 7.00 a.m. this morning. The satellite will spend the next 9 months floating in space. There it will enable scientists to test key measurement techniques for the detection of gravitational waves, which Albert Einstein predicted about 100 years ago in his general theory of relativity.

Plate tectonics thanks to plumes?
Plate tectonics thanks to plumes?
It is common knowledge that the Earth's rigid upper layer called lithosphere is composed of moving plates. But just what mechanism first set plate tectonics into motion still remains a mystery. A team of researchers led by ETH professor Taras Gerya has now come up with one possible answer by using simulations.

“It's scarcely possible to grasp intuitively”
“It’s scarcely possible to grasp intuitively”
In November 1915, Albert Einstein presented four seminal publications that laid the foundation for the general theory of relativity. A symposium at ETH Zurich celebrates its 100th anniversary from 12 to 14 November. ETH News: Hans-Rudolf Ott, you are one of the organisers of the symposium on 100 years of the general theory of relativity.

Surprising Discovery of Oxygen in Comet
Surprising Discovery of Oxygen in Comet
The biggest surprise so far in the chemical analysis of Comet Churyumov-Gerasimenko's atmosphere is the high proportion of oxygen molecules. While such molecules are common in the earth's atmosphere, their presence on comets had originally been ruled out. Early on in the mission of the ROSINA mass spectrometer, in September of last year, researchers from the Center for Space and Habitability (CSH) at the University of Bern made an unexpected discovery when analyzing the comet's gases: Between the expected peak values of sulfur and methanol, clear traces of oxygen (O2) molecules were detected.

Looking at the earliest galaxies
Looking at the earliest galaxies
22.10.15 - An international team of astronomers led by EPFL have discovered over 250 of the universe's earliest galaxies. This sample includes the faintest and smallest of the first-generation dwarf galaxies to be discovered, and offers important clues about the nature of the early universe.

Mysterious structures observed
Mysterious structures observed
A research team has observed structures racing out from the centre of a young star's debris disk at high speeds. It is still unclear what causes the phenomenon. "We were speechless when we saw the image for the first time in the control room at the observatory in Chile," remembers Christian Thalmann of the Institute for Astronomy at ETH Zurich, who is also a member of the National Centre of Competence in Research PlanetS and a Marie Curie fellow.

An army of tiny robots that tracks galaxies
An army of tiny robots that tracks galaxies
30.09.15 - Why is the universe expanding at an increasing rate? Scientists will attempt to gain a better understanding of this phenomenon by mapping the distribution of galaxies in the universe.

SwissCube's longevity marks its success
Launched more than five years ago, the small Swiss satellite designed by EPFL and several other Universities of Applied Sciences, will soon have orbited the Earth 30'000 times.

Detecting extraterrestrial life through motion
Detecting extraterrestrial life through motion
EPFL scientists have developed an extremely sensitive device that can detect life forms by sensing the slightest motion. The chemistry-free system can be used to rapidly test antibiotics or even to search for life on other planets. Looking for life on other planets is not straightforward. It usually relies on chemical detection, which might be limited or even completely irrelevant to alien biology.
