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
Red giants and our Sun are both in different phases of being a star, with the yellow dwarf Sun in its main sequence phase active and red giants nearer to their final phase. Red giants are 100 – 1000 times bigger than our sun and more luminous whilst the Sun is hotter and has a … Read more
The main differences between a type 1 and type 2 supernovae is that the first type is formed when a white dwarf explodes and leaves behind no hydrogen emissions whilst the other occurs when a larger star between 8 – 50 solar masses explodes, leaving behind hydrogen emissions. As both types are still supernova explosions, … Read more
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 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
Supernovae and neutron stars are interconnected as one precedes the other. Supernova explosions are simply the phase just before a neutron star is formed. The main differences between the two are that supernovae are over 100 times hotter, they’re many time larger in size and can also create black holes depending on the solar mass … Read more
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 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
Black holes and our Sun are completely different in many ways from the temperature they exude, where the sun is 6000°C and black holes nearly absolute zero, the significant discrepancy in density, luminosity along with different ways they affect the surrounding space around them. Black holes are formed after a star dies with anything that … Read more
One day on Venus is equal to around 243 Earth days! That’s longer than its year, which is only 225 Earth days. This slow rotation has baffled scientists for decades, though there are some theories as to what may be the cause of this phenomenon. One is the planet’s extremely dense atmosphere; the other is … Read more
