In pursuit of Ultima Thule in Senegal

On January 1, 2019, the American space probe New Horizons flew over the Thule Ultima asteroid. Located far beyond the planets of the Solar System, it is the most distant object ever explored by a human-made spacecraft.

A few months before the flight, American, Senegalese and French astronomers gathered in Senegal to prepare this unprecedented meeting more than 6 billion kilometers from Earth. An exceptional NASA mission made in Africa, with the participation of the team members of the African Initiative for Planetary and Space Sciences, to make a success of the meeting with Ultima Thule.

The film shot during the NASA Mission to Senegal in August 2018, with the support of MESRI (Senegal), ASPA, CNES, IRD and Uranoscope de France, is available online at the following link: https://youtu.be/Ow3O4bjxRm8

With “Vigie-Cratère”, become an impact crater hunter

Participate in the search for new impact craters thanks to the Vigie-Cratère participatory science program! This innovative platform, open to all, allows us to explore the relief of our planet to identify discrete or invisible circular structures on satellite imagery. This citizen science program, available in French and English, allows as many people as possible to learn more about impact processes and to help scientists better reconstruct the history of collisions with the Earth.

NASA mission in Senegal – A source of inspiration for young Senegalese scientists


Introductory words by David Baratoux (translation from French speech)
In presence of Maram KAIRE (ASPA), Heath Bailey (USA Embassy in Dakar), Laurent Perez-Vidal (French Embassy), and the public of the “Théâtre de Verdure” of the French Institute in Dakar

As we will discover tonight, the space exploration of our Solar System, the planetary and space sciences are areas that are not restricted to a few nations around the world.

These sciences are first of all a source of inspiration and motivation for young people who face the learning of mathematics, physics, chemistry, biology, or engineering sciences. Exploring the solar system leads to combine the learning of these fundamental disciplines, essential for innovation, with a huge part of dream, and also of excitement in front of the first images of new worlds, as we will discover one tonight. Participating in this adventure of space exploration of our solar system can play a role in education from primary school to university.

IAU symposium 356 – Nuclear Activity in Galaxies Across Cosmic Time

This is the second announcement of the IAU symposium 356 on ‘Nuclear
Activity in Galaxies Across Cosmic Time’, to be held in Addis Ababa in
Ethiopia, from October 7 – 11, 2019. We apologise if you received this
information multiple times. Please take a note that deadline for
abstract submission is next Tuesday 30 of April.

This is only the third symposium to be held in Africa in the past 100
years of the IAU. Currently many African countries are putting huge
efforts in developing astronomy and space science for their long-term
socioeconomic benefits. Therefore, beside revising the physics behind
AGN, another important aim of the IAU 356 symposium is to contribute to
the development of astronomy in Ethiopia and Africa in general. Please
help us in achieving these aims, by coming to the meeting and sharing
your knowledge and experience, and by
forwarding this information in your research centres and within your

Many thanks in advance, and we are looking forward to host you in

Best wishes, and have a nice day,

Mirjana Mpovic
on behalf of organisers

Second announcement
IAU symposium 356:
Nuclear Activity in Galaxies Across Cosmic Time
7 – 11 October 2019, Addis Ababa, Ethiopia


With this conference we would like to achieve two main goals. First, we
want to provide a general overview of recent findings and progress in
observations, simulations, and theory of AGN from the local universe up
to high redshifts. This includes the following questions:

1. What have we learnt from AGN multiwavelength studies and what can we
expect from future instruments such as eROSITA, JWST, Euclid, CTA, SKA,
E-ELT, Athena, etc.?

2. What is the current status of the unification model of AGN? What are
the components distinguishing type-1 and type-2 AGN?

3. What do we know about AGN host galaxies? What is the effect of AGN on
their host galaxy and how important is AGN feedback compared with
stellar feedback in the context of preserving (or not) SMBH scaling
relationships at low and high redshift?

4. What is the status of AGN theory and numerical simulations regarding
AGN triggering, including mergers and secular processes, AGN disks, AGN
outflows and the shutting off of AGN activity?

5. How well we understand the origin of jets and their impact on galaxy
evolution? What evidences do we have for AGN positive and negative
feedback across cosmic time? In what kind of environments AGN reside?

6. How precisely can we measure BH mass at different redshifts?

7. What are the properties of highest-redshift AGN? What do we know
about AGN evolution?
Secondly, we aim at strengthening the development of science in Ethiopia
and Africa and opening new space for collaborations between Africa and
other parts of the globe for the benefit of all.

– Multiwavelength AGN surveys: past, present, and future
– AGN types and unification
– Variability
– Active black holes and their host galaxies
– Triggering, feedback and shutting off AGN activity

Dear observer of the moon,

Thank to all of those who already registered for the On the Moon Again event. In less than 100 days, we will be numerous around the world to release our telescopes to share the beauty of the Moon with passersby. A map of all observers and educational content will be available by June on the on the Moon again website.

300 participants in 40 different countries have already registered. We hope that Africa will be widely represented !

Take the lead on your local On the Moon again event and communicate as you like about it (social networks, local newspapers, municipality, associations, …).

Feel free to use the flyer below (click to download a pdf version in french or english).


For your information, a photo contest will be organized to reward the most beautiful photos illustrating this event. Among the lots, we can announce that a lunar meteorite and several telescopes will be to win. More information will be sent by July.

Good spring to all!
The team On the Moon Again
