Science fiction tells us that black holes could act as portals to different dimensions in space or that they could be a vehicle for time travel. These mystical entities indeed warp spacetime, a large part of the reason being the influence of their gargantuan mass on their surroundings which will slow down time the closer … Read more
The main differences between Venus and Europa is that Venus is the hottest and brightest planet in our solar system and the 6th biggest planet whereas Europa is the most luminous moon in our solar system, orbits Jupiter and is the 6th largest moon in our solar system to boot. There are a variety of … Read more
The United States of America is the third largest country – by surface area – in the world. Still, while this land mass possesses an area of almost 10 million square kilometers, it falls short of the moon’s surface area. But what if we take the crust thickness into account? How does that affect the … Read more
The main differences between Mars and Europa would be that Mars is a normal terrestrial planet that orbits the Sun whilst Europa is the smallest of the Galilean moons that orbits Jupiter, Mars has 2 moons whilst Europa has 0 and Europa is colder on average with temperatures around -160°C whereas Mars averages -60°C on … Read more
Russia is smaller than Pluto, as the surface area covered by Russia is roughly 17.1 million km² whereas Pluto’s surface area is estimated to be slightly more (particularly after the New Horizons mission) with an overall surface area of 17.6 million km². In the past before the New Horizon mission, Pluto was estimated to be slightly smaller with a … Read more
Every planet in the solar system is speeding around our Sun at unfathomable speeds. Some planets travel much faster than others; it’s all to do with the gravitational force of the Sun and the velocity required to prevent them from falling into the hot mass of our central star. As a result the speeds at … Read more
We know there is gold on the moon thanks to the rock samples brought back to Earth during the Apollo missions. Knowing how much gold exists is more challenging because it’s buried deep below the surface, and current technology limits our ability to mine this precious metal. Continue reading to discover how much gold could … Read more
Australia is the sixth largest country on Earth and has an impressive diameter that stretches further than the moon’s width at 4,000km compared to the Moon’s diameter of 3474.8km. But this doesn’t mean Australia is bigger than the moon because its land mass is flat compared to the moon’s rounded body as its surface is … Read more
Mars does get closer to the Sun thanks to an elliptical orbit which provides it with both perihelion and aphelion phases. A number of factors affect the orbit of Mars, most significantly, the gravitational pull of the Sun and Jupiter. Continue reading to discover how and when Mars moves closer to the Sun, plus the … Read more
Supernovas and white holes are two of the most exciting phenomena in our universe, but the latter’s existence is only theoretical. Scientists have observed several supernova explosions, the brightest ones in the universe, but they have yet to observe any signs of a white hole. Continue reading to discover each of these entities and how … Read more
