Until now, most astronomers agreed that space has no top or bottom; in other words, the universe is expanding in all directions. But physicists Nodland and Ralston have challenged this principle.
Scientists from NASA's Cassini mission have captured thermal images from NASA's Mimas and Tethys satellites that are reminiscent of the Pacman or Pacman icon, the classic video game created in the 1980s. The photographs show the hottest areas of both bodies in yellow and have been published in Icarus magazine.
Every year around this time, the Earth is visited by a swarm of meteors that is called Leonidas. In 2012, NASA announced that the maximum peak of the Leonid Meteor Shower will be reached in the early morning of November 16-17, with some especially bright stars to be seen at sunrise. The Moon will be in a waxing phase and will set shortly after sunset.
A European team of astronomers has discovered a new planet orbiting a sun at the exact distance that would allow a climate similar to Earth's and that, therefore, could host liquid water on its surface and life. The star, named HD 40397, is a quiet old dwarf star 44 light-years from the solar system.
More than a hundred scientists, some Spanish, have teamed up to detect the elusive extragalactic background light or EBL (extragalactic background light). It is the set of photons generated by all the stars and black holes in the universe, and from which the oldest stellar emissions can be deduced. The study was made with data from the Fermi gamma-ray space telescope.
Using a nine-gigapixel image obtained by the VISTA infrared scanning telescope at the Paranal Observatory, an international team of astronomers has created the largest catalog to date of the center of the Milky Way, which includes 84 million stars, that is, ten times more than any previous image.
A huge black hole could be being ejected from its galaxy at several million kilometers per hour, according to a study carried out by scientists from the Smithsonian Institute of Astrophysics (USA). These findings also verify the existence of gravitational waves predicted by Einstein's theory of relativity.
A group of European astronomers has just discovered a planet of similar mass to Earth orbiting a star in the Alpha Centauri system, which is also the closest of these characteristics ever discovered. To achieve this finding, the researchers used the HARPS instrument installed at the La Silla Observatory of the European Southern Observatory (ESO).
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.
