Is liquid water necessary for life to form? If judging strictly from the only life we know, of course. However, humanity’s exploration of the universe has just begun, and we can’t say for sure what lies beyond Earth. Other worlds within our solar system have organic compounds that life could possibly evolve from. In particular, … Continue reading Methane-Based Life → Continue reading → Continue reading
What are exomoons? Well, we have already studied exoplanets (short for extra-solar planets) which are planets that are not from our star system. Accordingly, exo-moons are moons that orbit planets that orbit stars that aren’t the Sun. Sounds pretty cool, right? Well exomoons get even more interesting. In fact, exomoons are currently the subject of…
As we’ve seen in our study of the Jovian planets, the actual planets themselves aren’t the only important space-related object that provides useful and insightful information. Every Jovian planet has some sort of celestial object orbiting or surrounding it, especially the moons surrounding Jupiter. Discovered by Galileo Galilei way back in 1610 (on January 10th), … Continue reading Jupiter’s Eclectic Moons → Continue reading → Continue reading
Ok, this image may be a little deceiving. If you haven’t guessed already, I’m going to write a little about tidal heating. Tidal heating has nothing to do with making the tides on Earth catch on fire, I just thought that was a beautiful image and it made for a good pun. Tidal heating is … Continue reading A Different Kind Of Tide → Continue reading → Continue reading
Europa, a moon of the planet Jupiter, was discovered in 1610 by Galileo Galilei and Simon Marius. It is a little smaller than Earth’s moon, and it has one of the smoothest surfaces in the solar system. The surface is made up of water ice with long, linear lines fracturing it. The low number of … Continue reading Europa → Continue reading → Continue reading
Io is one of the closest and most prominent of Jupiter’s moons. Surprisingly, Io has the most volcanic activity of any of the worlds in our solar system. Usually, people think of moons as large barren rocks (similar to our own) however, Io breaks that mold. Because Io has such a large amount of volcanoes, … Continue reading Io → Continue reading → Continue reading
Galileo Galilei discovered many “luminous objects” in 1610 that were orbiting Jupiter. Thought to be stars, it was discovered that they were moons: Io, Europa, Ganymede and Callisto. Ganymede is the largest moon in the Solar System and is even larger than the planet Mercury. It is the only satellite in the Solar System known to possess a … Continue reading A Moon Above the Rest: Jupiter’s Moon Ganymede → Continue reading → Continue reading
The planet Mars was named after Mars, who to the Romans was the God of War. Its two moons, Phobos and Deimos, carry the names of the Greek Gods of fear (from which we get phobia) and terror, respectively. However, despite the naming scheme that seems to be inspired by Death Metal, Phobos and Deimos … Continue reading The Star-Crossed Fates of Phobos and Deimos → Continue reading → Continue reading
It makes sense that the tide comes in as the Moon approaches that side of the Earth. The gravitational pull attracts the water away from the Earth. It would seem them that logically a low tide would happen at a location farthest from the Moon. But that is not the case. image link In the … Continue reading Antipodal Tides Continue reading → Continue reading
SaltstraumenVideo Blocks The strait at Saltstraumen is one of the most interesting straits on the planet, and it has to do with more than just its notable beauty. Saltstraumen is the location of one of the strongest tidal currents in the world. When the tides come in and out from the large bodies of water … Continue reading “Current” Events on Tides → Continue reading → Continue reading
