The main differences between Dobsonian telescopes and refractor telescopes are that Dobsonian telescopes utilise mounts that only move up, down left and right at any given time while refractors can move in every direction depending on the mount used and premium refractive telescopes are often better than Dobsonian telescopes for astrophotography. For a more detailed … Read more
India is a good deal smaller than Jupiter’s moon, Europa, when landmass is considered coming in at around 3.28 million square kilometers, whereas Europa has 30.9 million square kilometers of land covered in a thick blanket of ice. As for volume India’s is 154.5 million cubic kilometers compared to Europa’s 15.9 billion cubic kilometers. For … Read more
Black holes are mysterious objects that can form when massive stars collapse. While they are usually solitary, there is a possibility for two black holes to orbit each other in a phenomenon known as a binary black hole system. Here, two companion black holes interact with each other through gravity and form an orbit. Continue … Read more
Australia is a good deal smaller than Jupiter’s moon, Europa, when landmass is considered coming in at around 7.6 million square kilometers, whereas Europa has 30.9 million square kilometers of land covered in a thick blanket of ice. In regards to volume Australia’s is 304 million cubic kilometers which is much smaller when compared to … Read more
China is a good deal smaller than Jupiter’s moon, Europa, when landmass is considered coming in at around 9.7 million square kilometers, whereas Europa has 30.9 million square kilometers of land covered in a thick blanket of ice. As for volume China’s is 462 million cubic kilometers which is much smaller than Europa’s 15.9 billion … Read more
Brazil is the fifth largest country on Earth, whilst Ganymede is the largest moon in our solar system. As a result Brazil is a flat land mass with a surface area of 8.5 million square kilometers and a volume of 340 million sq. kilometers while Ganymede is a spherical body with a surface area of … Read more
It is a widely accepted fact that all the planets in our solar system have cores made up of iron, nickel, and other metallic elements. These cores are essential in keeping the planets in their orbits and providing them with gravity. Continue reading to discover why planets have cores, whether or not they all contain … Read more
When we look into the night sky, we see a white moon, maybe yellow, and sometimes blue. But have you ever seen an orange moon? While a “blood moon” can appear as an orange hue, there are other reasons why you might spot this unusual-colored celestial body in the night sky. Continue reading to discover … Read more
Planets can orbit black holes, just as they can orbit any other large mass in space. However, sustaining life on one of these exoplanets would be challenging without the Sun’s energy, and it would have to exist within particular conditions for the theory to be feasible. Discover the conditions in which a planet (or even … Read more
The main reason why moons are not considered planets, even if they look very similar to them and in some cases are even larger than one, would be down to how planets are defined in currently. For a moon to be considered a planet, it must not only orbit a star and be in hydrostatic equilibrium … Read more
