New images of Comet 67P/Churyumov-Gerasimenko show that the target of ESA's Rosetta probe is no ordinary comet.
Comet 67P/Churyumov-Gerasimenko, was imaged on 14 July 2014 by OSIRIS, Rosetta's scientific imaging system, from a distance of approximately 12 000 km (image on the right).
The image suggests that the comet may consist of two parts: one segment seems to be rather elongated, while the other appears more bulbous.(learn more)

The International Astronomical Union has unveiled a worldwide contest, NameExoWorlds, which gives the public a role in naming planets and their host stars beyond the solar system. This contest is creating some controversy. Nonetheless, it is an interesting contest for teachers to work with their students. (learn more)

The little-known cloud of cosmic gas and dust called Gum 15 is the birthplace and home of hot young stars. Beautiful and deadly, these stars mould the appearance of their mother nebula and, as they progress into adulthood, will eventually also be the death of her. (learn more)

Recently initiatives that capitalise on the public’s interest in space and astronomy have proliferated, some putting a price tag on naming space objects and their features, such as Mars craters. The International Astronomical Union (IAU) would like to emphasise that such initiatives go against the spirit of free and equal access to space, as well as against internationally recognised standards. Hence no purchased names can ever be used on official maps and globes. The IAU encourages the public to become involved in the naming process of space objects and their features by following the officially recognised (and free) methods.(read more)

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in northern Chile have today announced the discovery of an unexpected clump of carbon monoxide gas in the dusty disc around the star Beta Pictoris. This is a surprise, as such gas is expected to be rapidly destroyed by starlight. Something — probably frequent collisions between small, icy objects such as comets — must be causing the gas to be continuously replenished. The new results are published today in the journal Science.(read more)

The NASA/ESA Hubble Space Telescope has photographed the never-before-seen break-up of an asteroid, which has fragmented into as many as ten smaller pieces. Although fragile comet nuclei have been seen to fall apart as they approach the Sun, nothing like the breakup of this asteroid, P/2013 R3, has ever been observed before in the asteroid belt.(read more)
A new innovative instrument called MUSE (Multi Unit Spectroscopic Explorer) has been successfully installed on ESO’s Very Large Telescope (VLT) at the Paranal Observatory in northern Chile. MUSE has observed distant galaxies, bright stars and other test targets during the first period of very successful observations. (read more)
This year ESA is once again organising a summer workshop for secondary school teachers of Science, Technology, Engineering and Mathematics (STEM) related subjects. The workshop will be held at ESA’s European Space Research and Technology Centre (ESTEC), located in Noordwijk, the Netherlands, from 21 - 25 July 2014. (learn more)
This new Hubble image shows spiral galaxy ESO 137-001, framed against a bright background as it moves through the heart of galaxy cluster Abell 3627. This cluster is violently ripping the spiral’s entrails out into space, leaving bright blue streaks as telltale clues to this cosmic crime. (read more)
The University of Huelva has released (see above) images of the high-speed impact of a wayward space rock on the surface of the moon last year triggered the brightest lunar explosion ever seen, scientists say.
Video footage of the record-breaking meteorite strike on the moon, which occurred on Sept. 11, 2013 and was unveiled today (Feb. 24), shows a long flash that was almost as bright as the North Star Polaris. That means the boulder-sized meteorite's lunar crash could have been visible to anyone on Earth who happened to be staring up at the moon at 8:07 p.m. GMT, weather permitting.
The following video is a simulation of the chain of events that leaded to the impact.

his new Hubble image is the best-ever view of a cosmic creepy-crawly known as the Tarantula Nebula, a region full of star clusters, glowing gas, and dark dust. Astronomers are exploring and mapping this nebula as part of the Hubble Tarantula Treasury Project, in a bid to try to understand its starry anatomy.(read more)
This image of Abell 2744 is the first to come from Hubble's Frontier Fields observing programme, which is using the magnifying power of enormous galaxy clusters to peer deep into the distant Universe. Abell 2744, nicknamed Pandora's Cluster, is thought to have a very violent history, having formed from a cosmic pile-up of multiple galaxy clusters. (read more)

Striking new observations with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope capture, for the first time, the remains of a recent supernova brimming with freshly formed dust. If enough of this dust makes the perilous transition into interstellar space, it could explain how many galaxies acquired their dusty, dusky appearance. (read more)
At the end of the EAAE Winter School held in Enontekio, Finland, the EAAE General Assembly has elected, on December 30th, the members of the Executive Council
The new Executive Council da EAAE has the following composition:
Alexandre Costa (Portugal) - President
Veselka Radeva (Bulgaria) - Vice-President
Alan Pickwick (UK) - Treasurer
Cristina Pallici di Suni (Italy) - Secretary
Miguel Neta (Portugal) - Editor/Webmaster
Ederlinda Viñuales (Spain) - Member of the board
Irma Hannula (Finland) - Member of the board
Janet Hilton (UK) - Member of the board
Sakari Ekko (Finland) - Member of the board
By proposal of the new EAAE President the former President Rosa Maria Ros was nominated Honorary President, an honour only given to Richard West (former Director of ESO) and Ferdinand Wagner (President of the EAAE between 2002 and 2009) in the past.
The EAAE General Assembly also decided which would be the active Working Groups for the next three years and selected their Chairpersons from people that have an historical relation in the work with these working groups.
The Working Groups Coordination was established as follows:
Ederlinda Viñuales (Spain) - Chairperson of WG1 - School Projects
Luana Fogli (Italy) - Chairperson of WG2 - Teacher's Network
Rosa Maria Ros (Spain) - Chairperson of WG3 - Teacher Summer Schools
The General Assembly wished the best of luck to all the new members in promoting the education of Astronomy in Europe.

In March of 2015, NASA's Dawn mission will arrive at the dwarf planet Ceres, the first of the smaller class of planets to be discovered and the closest to Earth. Ceres, which orbits the Sun in the asteroid belt between Mars and Jupiter, is a unique body in the Solar System, bearing many similarities to Jupiter's moon Europa and Saturn's moon Enceladus, both considered to bepotential sources for harboring life.

Perth, Australia (SPX) Dec 27, 2013 - Astronomers led by a Curtin University researcher have discovered a new population of exploding stars that "switch off" their radio transmissions before collapsing into a Black Hole. These exploding stars use all of their energy to emit one last strong beam of highly energetic radiation - known as a gamma-ray burst - before they die.(learn more)
