Survival Sweet Spot
Earth is a perfect amalgamation of all the conditions necessary for live to thrive. I always hear that the other terrestrials cannot sustain life, but never exactly sure how unsuitable they were. I mean if there was only one thing wrong with them, who’s to say we wouldn’t be able to invent a solution inContinue reading “Survival Sweet Spot” Continue reading
Mars, Water trapped in Rocks
An Artist’s Rendition of what Mars may have looked like 4 billion years ago As we have discussed in class, Mars looks very different today than it did billions of years ago. One notable difference is that Mars may have liquid water, as we see evidence of this in canyons and dried river beds inContinue reading “Mars, Water trapped in Rocks” Continue reading

Middle Man Mars
The terrestrial worlds are known to be Mercury, Venus, Earth, the moon, and Mars. While they all have some similarities to one another, like rocky surfaces and much smaller sizes than relative to the remaining planets in the solar system, they also have many differences. Venus and Earth are alike in ways that the otherContinue reading “Middle Man Mars” Continue reading
Retrograde Motion
Those in the realm of astrology are more than familiar with Mercury retrograde. During these unsettling periods, Mercury’s influence over matters of transportation and communication is altered which causes many unfortunate issues to arise. That is, of course, astrology’s interpretation of retrograde motion. In astronomy, retrograde motion simply describes the reversed direction planets seem toContinue reading “Retrograde Motion” Continue reading

Why Does Titan Have an Atmosphere?
It’s pretty perplexing as to why Saturn’s moon, Titan, has such a thick atmosphere but a planet like Mars does not. Since the most widely accepted explanation of why Mars has such a thin atmosphere is it losing its magnetosphere as its core cooled and does not contain nearly as much metallic iron has theContinue reading “Why Does Titan Have an Atmosphere?” Continue reading

A new possibility of life on Mars?
A photograph taken by the Mars Reconnaissance Orbiter (MRO) in 2011 has recently been released, showing what appears to be a sizable underground cavern on the slopes of Pavonis Mons, a Martian mountain standing 46,000 feet tall, higher than Mount Everest. The possibility of underground caves on Mars is exciting for (at least) two reasons:Continue reading “A new possibility of life on Mars?” Continue reading
How did mountains form on Venus?
Venus is often described as Earth’s sister planet. Both planets have similar size and densities, indicating somewhat similar core compositions. The primary difference between the two is orbital distance from the sun. Venus, like Earth, is covered with geological features including volcanoes and mountains. We know how mountains formed on Earth – tectonic plates. MountainsContinue reading “How did mountains form on Venus?” Continue reading
