A flysch is a sequence of sedimentary rocks that is deposited in a deep marine facies in the foreland basin of a developing orogen. Flysch is typically deposited during an early stage of the orogenesis. When the orogen evolves the foreland basin becomes shallower and molasse is deposited on top of the flysch. It is therefore called a syn-orogenic sediment (deposited contemporaneously with mountain building).

In the town of Zumaia along the Basque coast, northern Spain, are two beaches that contain a geologic treasure that contains millions of years of the Earth’s history.

The Itzurun and Santiago beaches are hotspots for geologists because it houses one of the longest continuous rock strata in the world called a ‘flysch.” This flysch in Zumaia was found to have formed over a period of over 100 million years by the crashing of the waves against the cliffs. The result is an abrasion platform with alternate hard layers (limestone and sandstone) and soft layers (clay and loam). The flysch extends eastward and westward from Zumaia, stretching a total of 8 kilometers to the towns of Deba and Getaria.

Apart from the impressive rock formations, Zumaia also harbors important fossil evidences. The Cretaceous-Paleogene boundary, a rock layer that marks the end of the Mesozoic era and the extinction of non-avian dinosaurs, is found in Itzurun beach. Fossils of ammonites, ancient molluscs resemblant of the nautilus, are also found in the rock layer.

Bring home the Universe!

Introducing the new and official Hey there, Universe online store! (powered by Amazon)

I have went through the entirety of the science-“cosm” on Amazon and have hand-picked a select few items that are featured here. Most notably, I want to introduce my followers to a list of my favorite science books, most of which are considered “popular science”, but some are also good reads for beginners, as well as experts who are interested in topics from other subjects.

Along with the books—which have been categorized into “Astrobiology, Biology, Astronomy, Physics, Geology”—I have also picked out some of my favorite apparel items on Amazon as well as gifts, toys, decors, for all of us who want to bring home the universe. 

I will try to promote this shop as little as possible (potentially 2 or 3 times a week), not every other hour, so don’t fret! The shop is run by me but all the transactions will be handled through Amazon. Feel free to give me a feedback on the store, or if you’re interested in seeing any specific item in the list. 

Lastly, if you are a college student (it’s back-to-school time again!), I would definitely recommend getting Amazon Prime! I’m sure you’ve heard of it by now, you get FREE Two-Day Shipping for one year just for signing up for Amazon Student. Click here to sign up today!

Howdy! The imagery on your page is stunning, so I wanted to tip my cap. I'm a fellow science enthusiast, sans all the advanced degrees. I studied political science and English, but I'm a compulsive reader of all things outer space. Hence, my blog is dedicated to the poetry and politics of spaceflight. Your following Armchair Cosmology is much appreciated. Keep up the great work and good luck on your ambition to become an astrobiologist.

Thank you!

Dear followers, please follow Armchair Cosmology for— yours truly— a poetic encounter with the world of space exploration, scientific bureaucracy, and as always, wonders of the universe. 

Welcome to the Tumblr science community, Armchair Cosmology!

The Youngness Paradox | The Daily Galaxy
According to MIT’s  Alan Guth , originator of the inflationary universe theory, our Universe is a product of eternal inflation —eternal into the future, but not into the past. An eternally inflating Universe produces an infinite number of pocket universes , which in turn are producing more new universes.  The old, mature universes are vastly outnumbered by universes that have just barely begun to evolve. Guth called it the “Youngness Paradox.”
Guth says that “the synchronous gauge probability distribution strongly implies that there is no civilization in the visible Universe more advanced than us. We would conclude, therefore, that it is extraordinarily improbable that there is a civilization in our pocket Universe that is at least one second more advanced than we are. Perhaps this argument explains why SETI has not found any signals from alien civilizations.”

In Guth’s view, “nature gets a lot of tries — the Universe is an experiment that’s repeated over and over again, each time with slightly different physical laws, or even vastly different physical laws,” says MIT physics professor Robert Jaffe.

Biologist warn of early stages of Earth’s sixth mass extinction event | ScienceDaily

The planet’s current biodiversity, the product of 3.5 billion years of evolutionary trial and error, is the highest in the history of life. But it may be reaching a tipping point. Scientists caution that the loss and decline of animals is contributing to what appears to be the early days of the planet’s sixth mass biological extinction event. Since 1500, more than 320 terrestrial vertebrates have become extinct. Populations of the remaining species show a 25 percent average decline in abundance. The situation is similarly dire for invertebrate animal life.
