The Picture of the day

"Termes d’astrofÝsica" a brief terminological compilation that offers solutions to denominate in catalan the terms of this field

Elaborated by: Jordi Miralda (DAM), online edition: UB Language Services.

UB Science Festival

On 22 May 2015, the University of Barcelona opens its door to citizens to celebrate the UB Science Festival.

Throughout the day, UB campuses organise different science dissemination activities





mÓxim The Dreadful Beauty of Medusa, 21 May
Astronomers using ESO’s Very Large Telescope in Chile have captured the most detailed image ever taken of the Medusa Nebula. As the star at the heart of this nebula made its transition into retirement, it shed its outer layers into space, forming this colourful cloud. The image foreshadows the final fate of the Sun, which will eventually also become an object of this kind

mÓxim The Dark Side of Star Clusters, 13 May
Observations with ESO’s Very Large Telescope in Chile have discovered a new class of “dark” globular star clusters around the giant galaxy Centaurus A. These mysterious objects look similar to normal clusters, but contain much more mass and may either harbour unexpected amounts of dark matter, or contain massive black holes — neither of which was expected nor is understood.

mÓxim Outreach talk: "Quiet Blak Holes hidden in Binary Systems" ,
Speaker: Marc Ribˇ
Date/Time: wednesday 13 May / 20:00
Place: Seu de l'Agrupaciˇ Astron˛mica Sabadell, C/ Prat de la Riba, s/n (Parc Catalunya), Sabadell

mÓxim Fresh Evidence for How Water Reached Earth Found in Asteroid Debris, 8 May
Water delivery via asteroids or comets is likely taking place in many other planetary systems, just as it happened on Earth, according to new research. The findings add further support to the possibility that water can be delivered to Earth-like planets via such bodies to create a suitable environment for the formation of life.

mÓxim Saturn Moon's Activity Could Be 'Curtain Eruptions', 7 May
New research using data from NASA's Cassini mission suggests most of the eruptions from Saturn's moon Enceladus might be diffuse curtains rather than discrete jets. Many features that appear to be individual jets of material erupting along the length of prominent fractures in the moon's south polar region might be phantoms created by an optical illusion, according to the new study.


mÓxim NASA’s New Horizons Detects Surface Features, Possible Polar Cap on Pluto, 30 April
For the first time, images from NASA’s New Horizons spacecraft are revealing bright and dark regions on the surface of faraway Pluto – the primary target of the New Horizons close flyby in mid-July.

mÓxim Saturn's sponge-like moon Hiperion, 29 April
The subject of this image bears a remarkable resemblance to a porous sea sponge, floating in the inky black surroundings of the deep sea.
Indeed, the cold, hostile and lonely environment of deep water is not too far removed from deep space, the actual setting for this image in which one of Saturn’s outer moons, Hyperion, can be seen in incredible detail. This image was taken by Cassini when the spacecraft performed a flyby of the small moon on 26 September 2005.

mÓxim 20 Exoworlds available for naming proposals, 27 April
The NameExoWorlds contest, organised by the IAU and Zooniverse, is now entering its next stage. The 20 most popular ExoWorlds have been made available for naming proposals from registered clubs and non-profit organisations.

mÓxim The Treasures of Hubble, 24 April
Today is the 25th anniversary of the launch of the Hubble Space Telescope. Astronomers at the European Space Astronomy Centre (ESAC) in Madrid, yesterday wished long life to Hubble and explained that more than half of current discoveries with the telescope are based on observations stored in the astronomical library of the ESAC.

mÓxim First Near Earth Asteroids Discovered from La Palma, 15 April
In 2014 the Isaac Newton Telescope became the first telescope in La Palma to discover and secure five Near Earth Asteroids (NEAs) as part of the EURONEAR project and as a result of the allocation of several override programmes awarded by the time allocation committees.

mÓxim Dark Energy Survey: mapping the dark matter of the Universe, 15 April
Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world's most powerful digital cameras, are the largest contiguous maps created at this level of detail and will improve our understanding of dark matter's role in the formation of galaxies. Analysis of the clumpiness of the dark matter in the maps will also allow scientists to probe the nature of the mysterious dark energy, believed to be causing the expansion of the universe to speed up.

mÓxim First Signs of Self-interacting Dark Matter?, 15 april
For the first time dark matter may have been observed interacting with other dark matter in a way other than through the force of gravity. Observations of colliding galaxies made with ESO’s Very Large Telescope and the NASA/ESA Hubble Space Telescope have picked up the first intriguing hints about the nature of this mysterious component of the Universe.

mÓxim Calling all Photographers,
For the launch of Sentinel-2A, ESA is inviting you to take part in a photo contest focusing on the theme of ‘colour vision’. Enter for a chance to win a trip to ESA’s operations centre for the satellite’s launch event.

mÓxim NASA host briefings on historic mission to Pluto,
NASA Television will air media briefings at 1 p.m. EDT and 2:30 p.m. on Tuesday, April 14, to discuss plans and related upcoming activities about the agency’s historic New Horizons spacecraft flyby of Pluto this summer.
Briefers will describe the mission’s goals, scientific objectives and encounter plans, including the types of images and other data that can be expected and when.

mÓxim Complex Organic Molecules Discovered in Infant Star System,
For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disc surrounding a young star. The discovery, made with the Atacama Large Millimeter/submillimeter Array (ALMA), reaffirms that the conditions that spawned the Earth and Sun are not unique in the Universe.

mÓxim NASA Extends Campaign for Public to Name Features on Pluto The public has until Friday, April 24 to help name new features on Pluto and its orbiting satellites as they are discovered by NASA’s New Horizons mission.

mÓxim Total Lunar Eclipse 4 April,
At 12:00 TU occurred a Total Lunar Eclipse visible from Asia, Australia, Pacific, America.

mÓxim Hershel and Planck find missing clue to galaxy cluster formation 1 April,
By combining observations of the distant Universe made with ESA’s Herschel and Planck space observatories, cosmologists have discovered what could be the precursors of the vast clusters of galaxies that we see today.
