A team of scientists from the Australian National University (ANU) has discovered the oldest known star so far, with an age of about 13,600 years, relegating to second place the other longest-lived star that dates back to 13.2 billion years. . The study has been published in the journal Nature.
The discovery of water on other planets is of the utmost importance to science. Now, thanks to ESA's Herschel space observatory, water vapor has been found for the first time in an object in the asteroid belt, the dwarf planet Ceres.
Improvements in technical equipment and scientific knowledge mean that we can increasingly measure everything around us with more precision. And not only that, because according to the data announced at the last annual meeting of the American Astronomical Society, an international group of researchers has managed to measure with a precision of 1% the distance to galaxies located more than 6,000 million light years from the Land. In other words, with unprecedented precision.
'In theory they should exist in the universe, but no one had been able to find one. However, now a team of Spanish researchers has located the first binary system formed by a black hole and a 'spinning top' star, as has just been published in the scientific journal Nature.
The Hubble telescope does not stop providing information about the history of the universe. In one of his latest images, he has obtained the best photo of some of the most distant and oldest galaxies, some 12,000 million light years away, thanks to the fact that the Abell 2744 cluster or 'Pandora cluster' has functioned as a kind of natural telescope gigantic.
An international team of astronomers has just discovered a very Earth-like planet orbiting a red dwarf star about 200 light-years from us. According to scientific calculations, it has a weight very similar to that of the Earth, but its diameter is 60% greater, which indicates that it must have a very thick gaseous atmosphere.
During the first days of each year, one of the most spectacular astronomical events occurs in the Northern Hemisphere, the Quadrantid Meteor Shower. This year 2014 will also be especially bright thanks to the fact that the Moon is in its new phase and the visualization of the comet remains will not be disturbed by its light.
