Looking at the night sky, one s thoughts might be drawn to astrochemistry. What molecules inhabit the vast spaces between the stars? Would we see the same molecules that surround us here on Earth? Or would some of them be more exotic something rarely observed or even unknown?
Recent research by a multinational team led by Prof. Robert Ko?os from the Institute of Physical Chemistry of the Polish Academy of Sciences has revealed an unusual molecule obtained and detected for the first time in laboratory conditions and also paved a smooth path to produce and further study another. Now that they can be seen and studied, they may prove worthy of wide ....

A monumental particle accelerator in the Cygnus Cocoon

At the heart of Cygnus, one of the most beautiful constellations of the summer sky, beats a source of high-energy cosmic ray particles: the Cygnus Cocoon. An international group of scientists at the HAWC observatory has gathered evidence that this vast astronomical structure is the most powerful of our galaxy s natural particle accelerators known of up to now. ....

LOS ALAMOS, N.M., March 11, 2021 A long-time question in astrophysics appears to finally be answered, thanks to a collection of large, high-tech water tanks on a mountainside in Mexico. The High-Altitude Water Cherenkov (HAWC) data shows that the highest-energy cosmic rays come not from supernovae, but from star clusters. ....

How the habitability of exoplanets is influenced by their rocks

The conditions on Earth are ideal for life. Most places on our planet are neither too hot nor too cold and offer liquid water. These and other requirements for life, however, delicately depend on the right composition of the atmosphere. Too little or too much of certain gases - like carbon dioxide - and Earth could become a ball of ice or turn into a pressure cooker. When scientists look for potentially habitable planets, a key component is therefore their atmosphere. ....

Scientists using NASA s Hubble Space Telescope have found evidence that a planet orbiting a distant star may have lost its atmosphere but gained a second one through volcanic activity.
The planet, GJ 1132 b, is hypothesized to have begun as a gaseous world with a thick hydrogen blanket of atmosphere. Starting out at several times the diameter of Earth, this so-called sub-Neptune is believed to have quickly lost its primordial hydrogen and helium atmosphere due to the intense radiation of the hot, young star it orbits. In a short period of time, such a planet would be stripped down to a bare core about the size of Earth. That s when things got interesting. ....
