A Golden Age of Collaborations

Join the webinar on 31st may 2022, 14:00 CEST

Astronomy is one of the few sciences where non-professional scientists equipped only with modest means can acquire data that opens new discoveries. In recent years professional astronomers have become more aware of the immense potential offered by professional and amateur collaborations, and a vast number of citizen science projects have flourished. These projects engage not only amateur astronomers, but also the general public who can actively participate in the scientific endeavour.

In this webinar, Ricardo Hueso will review some success stories in professional and amateur collaborations in planetary science including the ever-expanding field of exoplanets. A look forward to new missions and large telescopes in the next decade indicates that the golden age of Pro-Am collaborations in Solar System astronomy is far from its end, and that new projects will largely benefit from collaborations with the public. The Europlanet Society and Europlanet 2024 RI promote many of these collaborations through various of their different programs including the access to the Europlanet Telescope Network.

The webinar is led by Ricardo Hueso (Europlanet Society Executive Board)

Our friends from amateur astronomy in Portugal celebrate their "7th Concentration of Telescopes" on May 28 and 29. For some time now, and with the aim of strengthening ties, we have been talking about developing joint activities and participating in them as a single Iberian group. This is a good opportunity to strengthen this type of relationship under the sky and promote knowledge and coexistence among astronomers.

In addition to the outreach talks and scheduled cultural activities, the strong part of the meeting is the concentration of telescopes, so it is an excellent opportunity to attend with your own teams. There are also scheduled workshops on solar observation, photometry, telescope collimation and a used material fair.

These Conferences have the recognition of the Portuguese NOC of the IAU.

In this edition, a part of the program is reserved for Spanish associations, (Astronomical Association of Plasencia (Mintaka), Astróbriga of Ciudad Rodrigo and OSAE of Salamanca), in addition to the Federation itself.

Pro-Am Comet Community (Hybrid) Workshop

First Announcement and Call for Applications and Abstracts

10 – 12 June 2022, Prague




1: Call for a Medium-size and a Fast mission opportunity in ESA's Science Programme

The ESA Director of Science solicits the scientific community in ESA's Member States for proposals for both a "Fast" mission opportunity (to be launched in the 2030-2031 timeframe) and for a Medium mission opportunity (to be launched around 2037).  The new long-term scientific plan - Voyage 2050 - for the Science Programme of the European Space Agency (ESA), has been issued in June 2021, following a broad consultation of the scientific community and a peer review process, with final recommendations issued by an independent scientific Senior Committee. The plan includes three Large (L) missions in selected science themes (Moons of the Giant Planets, From Temperate Exoplanets to the Milky Way, and New Physical Probes of the Early Universe) and a set of Medium (M) and Fast (F) missions. The definition of the F and M space missions is based on a competitive, peer-reviewed selection process. Even though the Voyage 2050 plan identifies a set of possible themes for the Medium missions, proposals in all fields of space science will be considered, with no prejudice.

Full details can be found at:

2: Call for Membership in the Expert Committee for the Large mission covering the science theme “Moons of the Giant Planets”

The Director of Science at the European Space Agency (ESA) has issued a Call for Membership in the Expert Committee for the Large mission covering the science theme “Moons of the Giant Planets” that will support the initial definition of space mission concepts to fulfil the goals set for the “Moons of the Giant Planets” science theme.  This is the first scientific theme identified in the new long-term scientific plan (Voyage 2050) for the ESA Science Programme for the large mission following Athena and LISA. “Moons of the Giant Planets” addresses issues such as habitability, biosignatures, prebiotic chemistry, etc., to be implemented through a planetary probe to one of the moons of either Jupiter or Saturn.

Deadline for receipt of applications is 18 January 2022

The official magazine of Europlanet, the European community for planetary science.



This first issue has a strong focus on Mars, including European contributions to current missions, experimental research in labs and in the field, and outreach initiatives to engage the next generation. We look back at the origins of Europlanet and its links to the Cassini-Huygens mission at the beginning of this century. We also have updates on the Winchcombe meteorite and on several new partnerships to support planetary science.

Please check out Issue 1 and share with your networks to help us spread the word.

The second issue highlights some of the exciting science supported by Europlanet's transnational access program, including an experimental project to recreate Martian flows in the lab, field campaigns in Botswana and Greenland, and virtual access to facilities in Korea.


On May 15, a virtual workshop on the Europlanet Telescope Network (ETN) and access to the network by amateur astronomers was held. The workshop was jointly organized by the Europlanet 2024 RI, the Europlanet Society Regional Hub of Spain and Portugal, the Spanish Astronomy Society (SEA) and the Federation of Astronomical Associations of Spain (FAAE) with the additional collaboration of Calar Alto Observatory in Spain. The workshop had the active participation of some 70 people from Spain, Portugal, France and also from Latin America.
The information sessions, dissemination, practical application writing workshop and colloquium, were completed with a night of live remote observation with one of the ETN telescopes, the 1.23m telescope at Calar Alto observatory, during which observations were counducted of two comets, (C2021A1 and C2017K2), the transit of the exoplanet WASP-14b, and Saturn and its satellites covering examples of different topics open to the ETN program within the Pro-Am framework.

Recorded sessions


During the development of the night session, with observation objectives previously proposed by some of the participants, the raw data was shown, (without calibrating), as it was being generated which, in addition to its undoubted formative and didactic nature, has made this practical session much more enjoyable and highlights the potential of using telescopes, which are generally not available to amateur astronomers, when they become accessible to them.

Many amateur astronomers, who have extensive experience in astronomical data observations and analysis, can make valuable contributions to Pro-Am collaborations from telescopes in the ETN network.

However, one of the difficulties they may encounter is little or no experience in the subtleties of writing proposals for access to these resources. The main objective of this workshop has been to counteract this disadvantage and has dedicated the second of its sessions to this, in which the public information of the proposals approved so far has been analyzed and examples of studies that can be carried out by fans have been shown. with the telescopes of the network, highlighting the scientific contribution of these observations. Likewise, both the open call and the financing application form and the information that must be reflected in it under the appropriate approach to be accepted have been explained in detail.
A good example of the possibilities of the project are the results obtained during the practical session with the Calar Alto telescope, (in the picture above).
