How to represent on a map something that we cannot see? This is the question astronomers ask themselves when studying the dark matter in the Universe. This matter does not emit light or enough electromagnetic radiation to be detected with our technical means, however we can know it through its effects on visible matter.
A team of astronomers has detected for the first time around a nascent solar system an extensive cloud of water vapor cool enough to form comets that could deposit oceans on dry planets. It lies within the planet-forming disk surrounding the star TW Hydrae, 176 light-years away in the constellation Hydra, and contains volumes of water equivalent to thousands of Earth's oceans.
The 2011 Nobel Prize in Physics has recognized the work of three physicists - Saul Perlmutter (USA), Brian P. Schmidt (Australia) and Adam G. Riess (USA) - who discovered that the Universe is expanding at a rate each time accelerated by observing distant supernovae.
NASA's Johannes Kepler satellite has discovered a planet like Luke Skywalker's hometown in the Stars Wars movie, Tatooine. Baptized as 16-b, it has the same characteristics as the film: cold temperature, gaseous atmosphere and desert climate. It is also circumbinary, that is, it revolves around two stars.
A new technique consisting of joining radio telescopes from all over the world that work together, focusing simultaneously on the same source and simulating a single gigantic telescope has made it possible to obtain high-resolution images of distant galaxies.
Thanks to the Gran Telescopio Canarias (GTC), a pioneering study led by the researcher from the Instituto de Astrofísica de Canarias (IAC) Carlos M. Gutiérrez has identified three compact groups of galaxies located about five billion light years from Earth.
In 2004, physicists Andre Geim and Konstantin Novoselov synthesized graphene in the laboratory. Just seven years later, this material of extraordinary resistance could have been found in space by a team of Spanish astrophysicists.
Two teams of astronomers led by scientists from the Californa Institute of Technology (Caltech) have discovered the largest and most distant reservoir of water ever detected in the Universe. The mass of water found would be equivalent to several billion times that of all that exists on Earth.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
