Dear Colleagues, please distribute widely!

Find below exciting news for Astrobiology 2017. This
conference will take place in the beautiful Chilean Patagonia in
Coyhaique (November 26-December 1, 2017).

GRANT OPPORTUNITIES FOR GRADUATE STUDENTS

We are pleased to announce that there are funds available to
partially support a number of graduate students to attend Astrobiology
2017 (lodging grants and registration waivers). To apply click
http://astrobiology2017.org/student-grants/, and follow the instructions
therein. The application deadline is June 5, 2017, and we expect to
announce the recipients on June 17. If we still have grants available
after this date, there will be a second call for applications that will
precede the regular registration deadline.

EARLY REGISTRATION DEADLINE EXTENDED

To allow for students applying for grants to still make the early
registration deadline, the deadline has been extended until June 19,
2017. Please note that other key dates have not changed.

ORAL CONTRIBUTIONS

Oral contributions will be received until July 28, 2017. Please
note that a link to the abstract submission form is sent to you after
the registration process is completed. The SOC will select oral papers
after their review. The notification of acceptance will be sent by
August 25, 2017.

TRAINING SCHOOL

A two day training school with lectures on basics of Astrobiology
will take place in Santiago during the FridaySaturday preceding the
conference (November 24-25), and it is open to early-career
participants. There is no extra cost for participants of the conference
but only a maximum of 80 participants can be accommodated. Interested
participants of the TS should reserve a seat during registration,
Reservations for the training school are on a first come-first served
basis, so we urge you to register as soon as possible to secure a place.
For more information on the training school, including the program,
please click http://astrobiology2017.org/training-school/.

HOTEL RESERVATIONS

The registration platform also allows you to reserve your hotel
room at the discounted rates for Astrobiology 2017. While some hotels
are more flexible, the discounted rates for others are guaranteed only
until May 30th, 2017, so please, plan accordingly.

INVITED SPEAKERS

We have 26 superb confirmed invited speakers. The updated list can
be found at:  http://astrobiology2017.org/speakers/

(11819) Millarca


At the last Asteroids, Comets and Meteors (ACM) conference held in Montevideo, Uruguay (2017), a special award was handed out to Dr. Millarca Valenzuela, a member of Astrobiology 2017 Local Organizing Committee. Dr. Valenzuela is a geologist, expert in meteorites and planetary sciences and the official curator of the Chilean repository of meteorites. She was one of the recipients of an asteroid named on her behalf due to the significant contributions she has done to the field.

The Asteroid called “(11819) Millarca” was discovered at Siding Spring Observatory on March 3, 1981. It has been observed 663 times, the last of them this March. (11819) Millarca’s distance to the Sun varies from 497.700.000 to 401.980.000 kilometers. It is 254,4 million of km from Earth, and it takes 5,21 years to orbit the Sun.

The size of (11819) Millarca is between 4 km and 9 km, comparable to the surface of the Chilean island Robinson Crusoe.

For more information of this asteroid visit the Minor Planet Center of IAU webpage.

Coyhaique_2-1200x800.jpg

The main attraction of this city lies in their geography and the geomorphology of the principal geological structure. This part of Chile is characterized by glacial relief, with abrupt topography and a hydrographic system enriched by lake basins and numerous glaciers that flow into the Pacific Ocean.

The Patagonian Andes comprise a relatively low mountain belt, which bears witness of processes spanning from late Paleozoic to present. The average height is 900[m] and the highest mountain call San Valentin has 3900[m] of altitude approximately. San Valentin is the highest peak in the Chilean Patagonia and is between the General Carrera lake and San Rafael Lake. The backbone of the Patagonian Andes is the Mesozoic to Cenozoic Southern Patagonian batholith (SPB) whose earliest components intrude into low grade metamorphic complexes that crop out West and East of the continuous batholithic belt.

Andean magmatism is well developed in the foreland in two region, one of these is where the city of Coyhaique is located (between ~41°S and 44°S), where Paleocegene and Miocene andesitic to rhyolitic sequences, Eocene alkaline basalts and the extensive Late Oligocene to Miocene mafic plateau flows associated with the Mesetas de Somun Cura and Canquel occur.

The surprising shape of this place is controlled by the main structural factors: the union of three tectonic plates and the subduction of the Ridge of Chile.

The subduction between South American plate and Nazca plate has two main periods, between late Paleozoic-early Mesozoic and Jurassic to Present. The union of these two plates plus the Antarctic plate is called Triple Junction.

After the collision of the Chilean Ridge with the South American plate, the Triple Junction has migrated from south to north and is currently located in the peninsula of Taitao, near ~47°S. From ~38°S southward, the modern volcanic arc overlaps with the >900 km long Liquiñe-Ofqui Fault system, which has had dextral displacement since at least the Early Miocene.

In short, Coyhaique and its surroundings show all the complex geological processes that gave rise to the forms we see today, surprising all those who visit this southern part of Chile.

Come and meet Coyhaique in #astrobio2017, you will be surprised!
