Lake Vostok: Life in one of the most Inhospitable Places on Earth:

Located on the seemingly inhospitable continent of Antarctica (a place with the lowest recorded temperature on the Earth at -89 degrees Celsius), lies a subglacial lake that is 160 miles wide and 30 miles across. This lake has been dubbed Lake Vostok. It is believed that the lake formed some 20 million years ago. Isolated from the rest of the world for at LEAST 100 000 years, Lake Vostok was one of the last untouched places on this globe.

The lake presents itself as an analog for the study of both extremophilic microbial life (and possibly larger organisms) and evolutionary isolation. This inhospitable environment parallels some environments that we think might exist elsewhere in the solar system – either in the subsurface of Mars or on icy moons like Enceladus or even Europa. Ultimately, the search for life on other planets could start here on Earth at Lake Vostok.

Life and Moons in our Solar System: Europa

Most of us know about the 8 planets in our solar system (formerly 9 planets…poor Pluto). But you may not know too much about these planet’s moons. Some of these moons are strikingly similar to our own moon, but there are many that are vastly different and incredibly diverse. One such moon is Europa…

If One of Jupiter"s Moons Replaced Our Own...

Life is messy. It is turbulent and chaotic. However, in a world that is constantly evolving, there are a few things that we can rely on -- things that help keep life stable and keep us all sane. First, there is the Sun. It rises each day, giving us the light and energy that we need to survive, and then slowly slips behind the horizon (like clockwork).

The same is true of the Moon. Each night, it silently creeps through the sky; acting as a beacon of light in an increasingly dark world. Then, the sun peeks back up on the horizon, causing the moon"s presence to become less apparent for several hours -- until the cycle starts anew. One thing is for sure.. the moon is much more than a hunk of rock.. it"s a familiar, friendly figure. But what if the Moon wasn"t our moon? Furthermore, what would it be like if the Moon was replaced by another celestial body?

Astronomy Picture of the Day: 12/14/13 - Close Encounters of the Moon Kind

As Jupiter danced with the Moon on July 15 of last year, European observers had the spectacular chance to watch Jupiter pass behind the lunar disk. Cristian Fattinnanzi managed to capture this beautiful picture -- taken through light cloud cover over Montecassiano, Italy -- as the gas giant reemerged (with its four Galilean moons in tow).

The Galilean moons are names as such because Galileo discovered them while making his observations of our largest planet. The moons, pictured left to right, are Callisto, Ganymede, Io, and Europa; with Jupiter as the centerpiece.

Tidal Stresses - How Gravity Heats Things Up

Our planet is able to sustain warmth because of its atmosphere and its proximity to the Sun. However, as you may know, most of the other planets aren"t so lucky; nearly all of them have rather frigid temperatures.

For example, take a look at moons like Enceladus or Europa. These moons (of Saturn and Jupiter, respectively) are known as "icy moons." As a result of the extreme temperatures, which are hundreds of degrees below zero, both moons have a thick layer of ice many kilometers deep; however, we know that liquid water still exists on them. How can this be?

Drops of Jupiter

Earth is quite picturesque from a few thousand miles away. It is equipped with beautiful hues of green that are spread between large gaps of rolling seas of blue, and of course, there are large collections of fluffy white clouds that dance across the face of the planet. The images taken from this vantage point remind us that Earth is quite stunning. Out of the rest of the planets in our solar system, only one other planet (Jupiter) has the variety of colors that we are accustomed to seeing when viewing space-based images of our home planet. In all other cases, the bland, colorless worlds are a stark reminder that our planet is very much alive. Ultimately, Earth"s colors signify its abundance of life. However, in Jupiter"s atmosphere, the intense colors signify something entirely different...



So what do these colors mean? How does Jupiter stack up against our own planet?
