Binary Stars

A binary star is a star system of two stars that orbit around the central point, called the barycenter. In conversation, binary stars are sometimes casually referred to as double stars. Binary star systems or multiple star systems (3+ stars in orbit in the same system) are actually way more common than you might think.Continue reading “Binary Stars” Continue reading

The Danger of a Coronal Mass Ejection

A Coronal Mass Ejection (CME) is essentially a powerful expulsion of plasma and accompanying magnetic field from the solar corona, or the sort of aura of plasma that surrounds our Sun. While they have an extremely cool name, and seem pretty neat, they could actually have a pretty significant impact on humanity. The Sun has an incrediblyContinue reading “The Danger of a Coronal Mass Ejection” Continue reading

Spectroscopy and Stars

While it may seem impossible to be able to identify the types of elements that stars billions of light years away are made of, scientists discovered a way to do exactly that. In the 1850s, Kirchhoff and Bunsen managed to identify what the black lines in light spectra meant, and it allowed them to identifyContinue reading “Spectroscopy and Stars” Continue reading

Celestial Navigation in Disney’s Moana

Celestial Navigation was essential for Polynesian voyagers, and the Disney Film Moana does a very good job of depicting legitimate techniques. During the film’s production, Disney created a group of experts on the matter, including Polynesian elders and locals, called the Oceanic Story Trust. Their goal was to advise on cultural accuracy. Thousands of yearsContinue reading “Celestial Navigation in Disney’s Moana” Continue reading

Celestial Navigation

People have been using the stars to navigate for most of humankind. Six hundred years BC a philosopher called Thales of Miletos taught people to use the Little Bear constellation to navigate. What’s crazy is that those are the same stars that we say today! Despite there being other stars to navigate, the most common […] Continue reading

The Gravity of Neutron Stars

Apart from black holes, neutron stars are the densest objects in the universe – excluding some other weird stuff. These unique and very dense things can form after a star goes supernova and collapses. If the star is massive enough, the collapse will force protons and electrons to smash into each other to form neutrons.Continue reading “The Gravity of Neutron Stars” Continue reading

The Western Zodiac’s Origins

One of the most interesting aspects of Astronomy for me specifically is the element of spirituality or philosophy it tends to invoke. To witness the majesty and scale of universe evokes such wonder that, if you’ll allow some hyperbole, can at times be akin to a religious experience. I comment this not to say thatContinue reading “The Western Zodiac’s Origins” Continue reading
