When talking about the extraordinary natural landscapes of the Canary Islands, many still do not think of their skies and that these islands constitute an exceptional astronomical viewpoint in the world. With the aim of training professionals to help interpret the cultural and natural heritage of the Canarian sky, the IAC has launched the accreditation course for the first Starlight Guides.
More than 1,235 exoplanets await exploration outside the solar system, according to scientists who run NASA's Kepler space telescope. This graph, created by Jasson Rowe of NASA's Ames Research Center, shows the candidate stars ordered by size, with transiting exoplanets ahead of them.
American astronomers have discovered that the small, faint stars known as "red dwarfs" are much more prolific than previously thought, to the point that the total number of stars in the universe could be three times higher than estimated.
NASA's space telescopes have captured, 62 million light-years from Earth, a collision of two galaxies that began 100 million years ago and is still continuing. The image published by the space agency has been obtained by combining those taken by the cameras of the Chandra X-ray Observatory, the Hubble Space Telescope and Spitzer.
With a mass equivalent to 256 times that of our Sun, the star R136a1 is twice as large as any that has been seen before. This stellar "heavyweight" has been detected thanks to a combination of instruments from the Very Large Telescope of the European Southern Observatory (ESO).
Using the NASA and ESA Hubble Space Telescope, a team of German astronomers has succeeded in observing and measuring a cluster of young stars in the Milky Way moving at a uniform speed of 4.5 kilometers per second.
The European Southern Observatory (ESO) has released one of the most accurate and detailed portraits ever obtained of the nearby galaxy Messier 83, considered the "little sister" of the Milky Way. The image, captured with the HAWK-I instrument of ESO's Very Large Telescope (VLT) at the Paranal Observatory (Chile), shows the galaxy in infrared light and confirms the incredible power of this camera.
At the dawn of the universe, the galaxies in which stars were created contained between three and ten times more molecular gas than their current counterparts, according to a study led by researchers from the Max Planck Institute (Germany) and published today by Nature. The discovery, in which the Spanish astronomer Santiago Garcia-Burillo of the National Astronomical Observatory has participated, explains the high rate of star creation in young galaxies.
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.
