An international group of researchers led by Arnaud Belloche (MPIfR, Bonn, Germany) reports the first identification of isopropanol in interstellar space, a substance which is used as a sanitizer on Earth. Iso-propanol is the largest alcohol detected so far, demonstrating the increasing complexity of members of one of the most abundant classes of molecule that can be found in space...

Liquid water is an important prerequisite for life to develop on a planet. As researchers from the University of Bern, the University of Zurich and the National Centre of Competence in Research (NCCR) PlanetS report in a new study, liquid water could also exist for billions of years on planets that are very different from Earth. This calls our currently Earth-centred idea of potentially habitable planets into question.

Life on ...

For the past year, NASA’s Curiosity Mars rover has been traveling through a transition zone from a clay-rich region to one filled with a salty mineral called sulfate. While the science team targeted the clay-rich region and the sulfate-laden one for evidence each can offer about Mars’ watery past, the transition zone is proving to be scientifically fascinating as well...

Researchers have shown in a single model the full story of how gas travels in the center of the Milky Way — from being blown off by stars to falling into the black hole.

Looks can be deceiving. The light from an incandescent bulb seems steady, but it flickers 120 times per second. Because the brain only perceives an average of the information it receives, this flickering is blurred and the perception of constant illumination is a mere illusion.

While light cannot escape a black hole, the bright glow of rapidly orbiting gas (recall the images of M87’s black hole and Sgr A) has its own unique flicker. In a recent paper, published in Astrophysical Journal Letters, Lena Murchikova, William D...
