The Royal Observatory in Greenwich (United Kingdom) has awarded the prizes for the best astronomical photographs of 2014. The snapshots collect impressive moments from our solar system, the sky or the great space. In this year's edition, around 1,700 photographers, both professional and amateur, from 50 different countries have participated.
Thanks to data from NASA's Hubble Space Telescope, a team of astronomers has discovered that a dwarf galaxy is home to a supermassive black hole with a mass equivalent to 21 million suns, making it the smallest known galaxy to host a so massive object. This galaxy, which has a mass of 140 million solar masses, is approximately 54 million light years from Earth.
A team of experts from NASA's Chandra Observatory has discovered that a planet is aging the star it orbits as it is weakening its magnetic field. The planet in question is WASP-18b, located about 330 light years from Earth.
Scientists already have an answer to the question of what caused the last Ice Age on Earth and the consequent extinction of a wide variety of species. The culprit, according to a study by the University of Chicago (USA) is nothing more than an asteroid that impacted our planet about 12.8 billion years ago.
The Gaia space probe of the European Space Agency (ESA) has discovered, on its journey through the sky, its first stellar explosion in another galaxy. The event has been dubbed "Gaia14aaa" and it occurred in a distant galaxy some 500 million light years away.
The temperature of WISE J0304-2705, a peculiar celestial object similar to a planet, located between 33 and 55 light years away, could have reached that of some stars in its early evolutionary stages, while at present it is barely that of boiling water .
Although it does not pose a threat to us or to the satellites that surround the Earth, the proximity of an asteroid to our planet, not in vain will “brush” the Earth, makes the event worth taking into account.
