What Is A Blue Giant Star? (Explained!)

A blue giant star is a stellar body that is in the process of using its last remaining supplies of hydrogen. Thanks to its vast mass, a blue giant generates significantly more energy than other stars – R136a1, for example, generates more energy over four seconds than our Sun does in an entire year.

What Is A Kellner Eyepiece? (Explained!)

The Kellner eyepiece was designed in 1849 and has been a mainstay in the optics market ever since. It is considered to be the best of the beginner lenses. If you’re new to telescopes and want to bring stargazing into your hobby umbrella, you can’t do much better than to start with a Kellner. A … Read more

What Is The Black Eye Galaxy? (Explained!)

The Black Eye Galaxy is a barred spiral galaxy that lies 17 million light-years away from Earth. It gained fame after its discovery in 1779 for its unique “eye-like” appearance caused by a dust band that partially covers the galaxy’s nucleus. And the unique nature of this formation doesn’t end there. Continue reading to find … Read more

Pulsars vs Magnetars (How Are They Different?)

Pulsars and Magnetars are both the remnants of a dead star, specifically those that die after a supernova explosion. The main difference between the two is that magnetars have a magnetic field roughly 1000 times stronger than pulsars.  There are also other differences such as their difference in lifespan, the strength of rays that they … Read more

Supernova vs Hypernova (How Are They Different?)

Both hypernova and supernova explosions occur once nuclear fusion is unable to convert hydrogen into helium, forcing stars to collapse and produce these bright grandiose showcases. The main difference between a supernova and hypernova is that hypernova’s tend to be 5 – 50 times more powerful, caused when a star 30+ solar masses explodes and … Read more

Red Giant vs Red Supergiant (How Are They Different?)

Betelgeuse

Red giants and Red supergiants are both the final forms before stars become the dead remnant stars, where the smaller red giants become white dwarfs and the larger red supergiants will experience a supernova explosion, becoming either a neutron star or a black hole once the explosion settles down.  Continue reading for a more detailed … Read more
