Argentina 2020 Eclipse Expedition

Dec. 5 to 15, 2020


It is nature's most awe-inspiring spectacle. Engulfed as the Moon's shadow sweeps by, the world seems to turn upside down during totality. It's an emotional experience that can only be understood by those who experience it.

Tour leader Mike Simmons has chased eclipses since 1979. In 2006, Mike founded Astronomers Without Borders (AWB) to build relationships between people in different countries and cultures through the universal interest of astronomy. Mike has traveled the world meeting astronomy enthusiasts and educators connected by a passion to share our place in the Universe with others.

Now you can join Mike on these travels as OneSky Expeditions brings astronomy community members face-to-face. We’ll learn about each other’s cultures and what astronomy means to each of us. Our similarities far outweigh the differences. It's sightseeing and nature's grandest spectacle with an added dimension.

Itinerary days devoted to AWB programs:

We leave the tourist trail behind as we meet with fellow astronomers, educators, and fellow members of the worldwide astronomy community. While details are still shaping up, activities will likely include visiting schools to hand out eclipse glasses and give presentations, meeting amateur astronomers, observing the best objects of the southern skies , and more.


Mike Simmons, Eclipse Chaser, Astronomer, Educator

Renowned outreach astronomer, eclipse chaser, and Founder and Past President of Astronomers Without Borders (AWB) Mike Simmons will be leading your eclipse tour.  Mike has been sharing astronomy with the public for more than 40 years, and has been an total eclipse chaser since 1979. With a passion for sharing celestial and cultural experiences with others, Mike has chased eclipses to far-flung locations around the world, from China to Iran to a peak in the Andes of South America.


Interactions with locals during an eclipse trip showed Mike how astronomy is a universal interest that transcends cultural differences. In 2006, Mike founded Astronomers Without Borders to unite astronomy and space enthusiasts around the world through these common interests. During the International Year of Astronomy in 2009, Mike led 100 Hours of Astronomy, the largest global astronomy event ever. He is now widely recognized as a leader in astronomy activities worldwide.

Mike is also a writer and photographer, having contributed to Scientific American, Astronomy, and Sky and Telescope where he is a Contributing Editor. He regularly gives public talks, both in the US and abroad, on his experiences and his views on breaking down cultural, religious and political borders and improving international relations through astronomy.

The abundance of afterbirth and young pups here attracts the attention of several scavengers and predators, including the striking Killer Whales that are known to beach themselves along this coastline to capture prey, as well as Southern Giant Petrel and unique Snowy Sheathbill that forage through the remains. The rocky coastline may hold Imperial and Rock Shags alongside the commoner Neotropic Cormorants. 



Estancia San Lorenzo- Land of PenguinsSan Lorenzo is a sheep farm stretching over 5,000 hectares has a 4600-meter-long coastline on the San Matias Bay. On the property there is an awesome breeding colony of Magellanic penguins with approximately 200,000 penguins including both adults and juveniles.  Together with Magellanic penguins, San Lorenzo offers the possibility of observing elephant seals, guanacos, rheas, owls, cavies and a great diversity of birds. Eventually, also Right whales and orca can be sighted. The activities offered by Estancia San Lorenzo will bring you closer to nature. There are also places to spot fossilized giant oysters.


The Valdés Peninsula is renowned for its large population of marine wildlife but with over 180 different bird species migrating to the peninsula or living here throughout the year, it’s also one of the most important birding destinations in Argentina. Expect to see: South American, royal and sandwich terns, Black-browed albatross, Southern giant petrel, Blackish and American oystercatchers, Magellanic penguin, Brown skua, Variable hawk, Great egret, Turkey vulture & Burrowing parrot.


Return back to Hotel in Puerto Madryn in the evening. YENE HUE HOTEL – BL 



Breakfast at the Hotel. The whale watching trip starts from a small village called Puerto Piramids. Going along the coast on both sides, the first stop is at La Lobería (sea lion colony), which is closer to Puerto Pirámides and has got 2000 specimens of whales. Sail along the coast allows us to watch many cormorant colonies. They build their nests against the cliff and there they also breed and raise their babies. Cruise also offers opportunity to observe and photograph other specimens of the coastal bird fauna.  The engines are stopped when the ship gets far from the coast, silence interrupted only by the sounds of penguins, seagulls, gulls and cormorants. Something silvery and white jumps next to the ship and the strong sound of a body splashing the sea are heard. To complete this feast some dolphins always show up to jump and play in complete freedom along the Whales. Enjoy lunch at the village before returning to Puerto Madryn.YENE HUE HOTEL – BL
