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.
A team of German astronomers has found a Jupiter-like exoplanet orbiting a star of extragalactic origin that the Milky Way "devoured", in an act of galactic cannibalism, between six and nine billion years ago.
NASA's Fermi Gamma-ray Space Telescope has revealed the existence of a huge and hitherto unknown structure in the center of the Milky Way. They are two bubbles of 25,000 light years each that extend north and south of the galaxy.
This is the conclusion reached by a team of astronomers from the University of California, Berkeley, after studying 166 stars of type G (like the Sun) and type K, less than 80 light years away from our planet, with help from the Keck telescopes of Hawaii.
NASA's Solar Dynamic Observatory (SDO) has captured for the first time the transit of the Moon in front of the Sun from a probe in space. The image, obtained 36,000 kilometers from Earth, shows a spectacular "partial eclipse of the Sun".
To weigh a star located billions of kilometers away, neither scales nor scales work. But astrophysicist David Kipping of Harvard University has discovered that it is possible to calculate the exact weight of a star using a moon.
After completing its main mission of composing a map of the sky in infrared light, the WISE space telescope has reached the end point of its internal coolant supply, essential for its mission. Despite this assuming that WISE is starting to "heat up", NASA has decided that the mission will continue. The telescope will now focus on our closest neighbors: asteroids and comets.
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.
