Ganymede (Jupiter III)

Ganymede is the largest moon of Jupiter. It also happens to be the largest moon in our Solar System. Bigger than planet Mercury actually. It was discovered by Simon Marius in 1610, who named it Ganymede, after Zeus' cup-bearer. Its diameter is 5,268.2 km and it takes 7 days and 3 hours for it to orbit Jupiter. Ganymede's distance from Big J is 1.070 million km. Ganymede's core is iron-rich and liquid, it also has an internal ocean, [...]

Io

If you've ever wondered where the actual hell could be located (if it were real), I'm here to tell you it would be in our Solar System. On Jupiter's moon Io, actually. It was named Io (which means "moon" in ancient greek) after one of Zeus' lovers. This little guy is packed with about 400 active volcanoes. In fact, it is the most active (volcanically) body in our Solar System. A total badass! It's a bit bigger [...]

Let’s mine the Moon

The Moon. My favorite cosmic object. What do we know about the Moon? Quite a lot in fact. We know that the Moon - Earth’s only natural satellite - was formed about 4.5 billion years ago as a result of collision between Earth and Theia. Theia was this gigantic Mars-sized object. Some call those “planetoids”. The Moon orbits the Earth, has a 29.5-day cycle, shows the same side to us (hence the conspiracy theories about the dark side of [...]

Zero Gravity and Disease

How Does Zero Gravity React With Diseases? Zero gravity can be defined as the complete absence of sensation of weight in an environment. It usually happens when there are no contact forces on objects such as a human body. Zero Gravity and Diseases Being in a zero-gravity environment for an extended period can have many negative impacts on the human body. This phenomenon cannot be used to treat a specific medical condition, the environment itself can lead to the [...]

Europa (Jupiter II)

Europa is one of 79 and the 4th largest moon of Jupiter. It was discovered by Simon Marius in 1609, who named it "Europa", after a princess from Greek Mythology. Its diameter is 3121.6km, just a bit smaller than Earth's moon. It takes roughly 3.5 days for Europa to orbit Jupiter. Europa's distance from Jupiter is about 670.900km.  Scientists believe that Europa has an iron core and an atmosphere (mostly oxygen). The surface is smooth and icy. Under [...]

The Moon (Luna)

The Moon(or Luna) is Earth's only natural satellite. It was created as a result of collision between Earth and Mars-sized protoplanet Teia 4.53 billion years ago. It's 384399 km away from Earth and moves away from our planet at a rate of 3.8 cm per year. The Moon's gravity is 1/6 of Earth's and it has no atmosphere. In 2009 NASA announced that they have found water on the moon. The Moon's cycle is 29 days, 12 hours, [...]

Abandon ship, or fix it?

Should we fix earth or just colonize another planet? As NASA and Elon Musk continue to spend top dollar on space exploration, talks of living on planets outside our earth are filtering into the air. In fact, Elon Musk said that the cost of moving to Mars with a free return ticket would be around $500,000 or lesser in the future. Ok, but, what happens if we are successful men those planets? Where do we start from? How do [...]
