ServiAstro is the website for public outreach on astronomy of the Astronomy and Meteorology Department (DAM) of the University of Barcelona.

It offers information about the past and future astronomical events visible from Catalonia. Also about the most important ones, no matter the geographical visibility. In some especially outstanding cases, such as planetary transits or Solar and Lunar eclipses, ServiAstro offers live webcasts which can be enjoyed anytime, thanks to our permanent galleries.

Furthermore, ServiAstro publish the public outreach activities carried out by the (DAM). Visitors will find a compilation of astronomical ephemerides, tools for astronomical calculations, news, answers to frequently asked questions and links to lots of other websites about astronomy, organized in sections.

Physics Photo Contest «International Year of light»

On 20 December 2013 the General Assembly of the United Nations proclaimed 2015 the International Year of Light and light-based technologies.

The "Catalan Society of Physics", a subsidiary of the "Institute of Catalan Studies", wants to join in the celebration with this call, with the aim of encouraging interest in optics and physics in our society, and to support the emergence of careers in these fields.

mąxim Bizarre nearby blast mimics Universe'smost ancient stars 11 July 2014,
ESA’s XMM-Newton observatory has helped to uncover how the Universe’s first stars ended their lives in giant explosions.
Astronomers studied the gamma-ray burst GRB130925A – a flash of very energetic radiation streaming from a star in a distant galaxy 5.6 billion light years from Earth – using space- and ground-based observatories.

mąxim NASA Spacecraft Observes Further Evidence of Dry Ice Gullies on Mars 10 July 2014,
Repeated high-resolution observations made by NASA’s Mars Reconnaissance Orbiter (MRO) indicate the gullies on Mars’ surface are primarily formed by the seasonal freezing of carbon dioxide, not liquid water.

mąxim NameExoWorlds: An IAU World wide Contest to name Exoplanets and their Host Stars 9 July 2014,
For the first time, in response to the public’s increased interest in being part of discoveries in astronomy, the International Astronomical Union (IAU) is organizing a worldwide contest to give popular names to selected exoplanets along with their host stars. The proposed names will be submitted by astronomy clubs and non-profit organisations interested in astronomy, and votes will be cast by the public from across the world through the web platform NameExoWorlds.

mąxim VLT Clears Up Dusty Mystery 9 July 2014,
A group of astronomers has been able to follow stardust being made in real time — during the aftermath of a supernova explosion. For the first time they show that these cosmic dust factories make their grains in a two-stage process, starting soon after the explosion, but continuing for years afterwards.

mąxim Farewell Lutetia! 7 July 2014,
This ethereal image shows a stunning sliver of large main-belt asteroid Lutetia from the viewpoint of ESA’s Rosetta spacecraft, taken as Rosetta passed by on its 10-year voyage towards comet 67P/Churyumov–Gerasimenko.

mąxim Ocean on Saturn Moon Could be as Salty as the Dead Sea 2 July 2014,
scientists analyzing data from NASA’s Cassini mission have firm evidence the ocean inside Saturn's largest moon, Titan, might be as salty as the Earth's Dead Sea.

mąxim Young sun'sviolent history solves meteorite mystery 1 July 2014
, Astronomers using ESA’s Herschel space observatory to probe the turbulent beginnings of a Sun-like star have found evidence of mighty stellar winds that could solve a puzzling meteorite mystery in our own back yard.

mąxim Nanda Rea receives the Zeldovich Medal 1 July 2014
, Dr. Nanda Rea, research scientist of the Institute of Space Sciences (CSIC) / Institute of Space Studies of Catalunya (IEEC), receives the Zeldovich Medal, awarded by the Committee on Space Research (COSPAR) and the Russian Academy of Sciences.

mąxim Discovery of Near Earth Asteroid 2014 LU14 with the Isaac Newton Telescope 1 July 2014,
LU14 is the first Near Earth Asteroid (NEA) discovered using the Isaac Newton Telescope and the first ever from La Palma. Having an absolute magnitude of H=18.6, the discovered NEA has an estimated size of about half a kilometer (assuming a mean albedo of 0.2), and will become better visible in July 2014 (estimated magnitude V=20).

mąxim Puzzling X rays point to dark matter 17 June
Astronomers using ESA and NASA high-energy observatories have discovered a tantalising clue that hints at an elusive ingredient of our Universe: dark matter.

mąxim New moleculas around old starss 17 June
Using ESA’s Herschel space observatory, astronomers have discovered that a molecule vital for creating water exists in the burning embers of dying Sun-like stars.

mąxim Gigantic Explosions Buried in Dust 14 June
Observations from the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time directly mapped out the molecular gas and dust in the host galaxies of gamma-ray bursts (GRBs) — the biggest explosions in the Universe.

mąxim Black Hole ‘Batteries’ Keep Blazars Going and Going 3 June
Astronomers studying two classes of black-hole-powered galaxies monitored by NASA's Fermi Gamma-ray Space Telescope have found evidence that they represent different sides of the same cosmic coin. By unraveling how these objects, called blazars, are distributed throughout the universe, the scientists suggest that apparently distinctive properties defining each class more likely reflect a change in the way the galaxies extract energy from their central black holes.

mąxim Astronomers Confounded By Massive Rocky World 2 June
Astronomers have discovered a rocky planet that weighs 17 times as much as Earth and is more than twice as large in size. This discovery has planet formation theorists challenged to explain how such a world could have formed.
