Comet Records From 1240 Accurately Date When a Byzantine Princess Died

Rome was the world’s first mega-empire. At its height it stretched from Western Europe to the Middle East, and over 50 million souls lived within its borders. Some historians think that number could’ve been way higher, up to 100 million.

Rome got its start in the mid-8th century BC. It took centuries for that small city to grow into the Roman Empire, which reached its peak around AD 100. A well-known cliche reminds us how long that took.

But the Roman Empire also took centuries to fracture and dissolve.

Geologists Have Found the Earth’s Missing Tectonic Plate

Northern Canada has been keeping a secret from the rest of the world. It’s home to “Resurrection,” a tectonic plate that has been much theorized but never found until now. A team of researchers used what amounts to a CAT scan of northern Canada and the mantle underneath it to find the missing plate.

Finding it could lead to better hazard prediction and also to finding mineral and hydrocarbon deposits. But better than that, it’s helping scientists piece together Earth’s history.

A History of the Magellanic Clouds and How They Got Their Names

The Magellanic Clouds are a pair of dwarf galaxies that are bound to the Milky Way. The Milky Way is slowly consuming them in Borg-like fashion, starting with the gas halo that surrounds both Clouds. They’re visible in the southern sky, and for centuries people have gazed up at them. They’re named after the Portuguese explorer Ferdinand Magellan, in our current times.

But they weren’t always called that.

Remembering Don Arabian, the ‘Mad Genius’ Behind NASA’s Apollo Engineering Team

One of the truly unsung heroes of the Apollo program has passed away at age 95. Donald D. Arabian, Chief of the Apollo Test Division, headed the Mission Evaluation Room (MER), which was responsible for solving in-flight problems during the Apollo missions to the Moon.  

His nickname was “Mad Don,” and anyone who had the privilege of meeting him or working with him described Arabian as “one of a kind,” “colorful,” and “completely and totally unforgettable.” But in the book “Apollo: Race to the Moon” authors Charles Murray and Catherine Bly Cox designated Arabian as one of four people responsible for the success of the Apollo Program.

Martian Features Were Carved by Glaciers, not Flowing Rivers

Orbiters are giving us a chance to study the surface of Mars closely, and some of the features that pop to prominence are dry river channels. There are over 10,000 of them. But a new study suggests that glaciers on ancient Mars are responsible for many of them.

According to the study, those glaciers and the water flowing under them are resonsible for carving out some of those riverbeds, rather than free-flowing rivers.

Five Space and Astronomy Activities to do at Home During the Coronavirus Outbreak

We’re in uncharted territory as the world faces the Coronavirus (COVID-19) pandemic. While the medical community is on the front lines of dealing with this, as well as others who provide critical services in our communities, the best thing many of us can do is to stay home (and wash our hands).

If you’re looking for ways to keep occupied, keep your kids in learning-mode while school is canceled, and expand your horizons — all at the same time — luckily there are lots of space and astronomy-related activities you can do at home and online. We’ve compiled a few of our favorites, including this first one, one that just became available yesterday.

3 Billion Years Ago, the World Might Have Been a Waterworld, With No Continents At All

Evidence from an ancient section of the Earth’s crust suggest that Earth was once a water-world, some three billion years ago. If true, it’ll mean scientists need to reconsider some thinking around exoplanets and habitability. They’ll also need to reconsider their understanding of how life began on our planet.

Who was Aristotle?

Philosopher, polymath, educator, synthesist, founder. These are just some of the words used to describe Aristotle, the 4th century BCE Greek luminary who (along with Plato) is known as the “father of Western philosophy.” With subjects ranging from physics, biology, and astronomy to logic, ethics, politics, and metaphysics, there is scarcely any field of study or subject that he did not have a significant and lasting impact on.

In fact, within the realm of astronomy and physics, Artistotle would be one of the leading authorities whose work would be considered canon for over two thousand years after his death. From Classical Antiquity to the Roman Empire to the Middle Ages and the Rennaissance, Aristotle would be considered the authoritative source on countless subjects.
