Cosmic web orchestrates the progression of galaxies
Cosmic web orchestrates the progression of galaxies
The shape of galaxies and how they evolve depend on a web of cosmological filaments that run across the Universe. According to a recent study headed by EPFL's Laboratory of Astrophysics, this cosmic web plays a much bigger role than previously thought. Across the Universe, galaxies are distributed along what's called the cosmic web, a complex network of filaments made up of ordinary and dark matter.

The upside-down orbits of a multi-planetary system
The upside-down orbits of a multi-planetary system
Astronomers led by the UNIGE have discovered exoplanets that orbit in planes at 90 degrees from each other. When planets form, they usually continue their orbital evolution in the equatorial plane of their star. However, an international team, led by astronomers from the University of Geneva , Switzerland, has discovered that the exoplanets of a star in the constellation Pisces orbit in planes perpendicular to each other, with the innermost planet the only one still orbiting in the equatorial plane.

The planet does not fall far from the star
The planet does not fall far from the star
A compositional link between planets and their respective host star has long been assumed in astronomy. For the first time now, a team of scientists, with the participation of researchers of the National Centre of Competence in Research (NCCR) PlanetS from the University of Bern and the University of Zürich, deliver empirical evidence to support the assumption - and partly contradict it at the same time.

Did Venus, Earth's twin sister, ever have oceans?
Did Venus, Earth’s twin sister, ever have oceans?
Astrophysicists led by the UNIGE and the NCCR PlanetS have investigated the past of Venus to find out whether Earth's sister planet once had oceans. The planet Venus can be seen as the Earth's evil twin. At first sight, it is of comparable mass and size as our home planet, similarly consists mostly of rocky material, holds some water and has an atmosphere.

Very old Universe reveals new galaxies
Very old Universe reveals new galaxies
Scientists serendipitously discover two heavily dust-enshrouded galaxies that formed when the Universe was only 5% of its present age. While investigating the data of young, distant galaxies observed with the Atacama Large Millimeter/submillimeter Array, Yoshinobu Fudamoto from Waseda University and the National Astronomical Observatory of Japan noticed unexpected emissions coming from seemingly empty regions in space that, a global research team confirmed, came actually from two hitherto undiscovered galaxies heavily obscured by cosmic dust.

Surprise: the Milky Way is not homogeneous
Surprise: the Milky Way is not homogeneous
Astronomers from the UNIGE have observed the composition of the gases in our galaxy and have shown that, contrary to the models established until now, they are not homogeneously mixed. In order to better understand the history and evolution of the Milky Way, astronomers are studying the composition of the gases and metals that make up an important part of our galaxy.

Researchers from IRSOL and IAC solve twenty-year-old paradox in solar physics
Researchers from IRSOL and IAC solve twenty-year-old paradox in solar physics
In 1998, the journal Nature published a seminal letter concluding that a mysterious signal, which had been recently discovered analysing the polarization of sunlight, implies that the solar chromosphere (a very important layer of the solar atmosphere) is practically unmagnetised, in sharp contradiction with common wisdom.

Small force, big effect: How the planets could influence the sun
Small force, big effect: How the planets could influence the sun
A new theory supports the controversial hypothesis that the planets affect solar activity. It puts forward a mechanism by which the very small influence of the planets could exert its rhythm on such a large system as the Sun. If the theory is confirmed, it could possibly be used to predict solar activity more accurately.

On eternal imbalance
On eternal imbalance
Some physical systems, especially in the quantum world, do not reach a stable equilibrium even after a long time. An ETH researcher has now found an elegant explanation for this phenomenon. If you put a bottle of beer in a big bathtub full of ice-cold water, it won't be long before you can enjoy a cold beer.

Advancing to the core thanks to marsquakes
Advancing to the core thanks to marsquakes
Researchers at ETH Zurich and the University of Zurich have been able to use seismic data to look inside Mars for the first time. Marsquakes recorded by NASA's InSight lander provided information about the structure of the planet's crust, mantle and core. We know that Earth is made up of layers: a thin crust of light, solid rock surrounds a thick mantle of heavy, viscous rock, which in turn envelopes a core consisting mainly of iron and nickel.
