Remarkable events

màxim Planet Found in Habitable Zone Around Nearest Star, 25/08/2016
Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us — and it may also be the closest possible abode for life outside the Solar System.

màxim One second more in 2016, 6/07/2016,
The International Earth Rotation and Reference System Service (IERS), announced that on 31 December 2016 will add a second to our clock time (UTC) to adjust it with the Solar Time (UT). This Time difference corresponds to the variability of the terrestrial rotation.

màxim Juno in orbit around Jupiter, 05/07/2016
After an almost five-year journey to the solar system’s largest planet, NASA's Juno spacecraft successfully entered Jupiter’s orbit during a 35-minute engine burn. Confirmation that the burn had completed was received on Earth at 8:53 p.m. PDT (11:53 p.m. EDT) Monday, July 4.

màxim Gaia data release set for 14 September, 04/07/2016
ESA's billion-star surveyor Gaia, launched on 19 December 2013, and in routine science operations since 25 July 2014, will release the first mission data on 14 September 2016.
transit Mercu6en.jpg TransitMercuri090516
On 9th May a transit of Mercury will be visible from Catalonia. The transit will begin at midday and will end with the sunset.Transits of Mercury cannot be seen with the naked eye. You need a telescope for a good observation.

màxim LIGO Detected Gravitational Waves from Black Holes, 12 February 2016
On September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC), the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA both measured ripples in the fabric of spacetime – gravitational waves – arriving at the Earth from a cataclysmic event in the distant universe.
