Tardigrades: Unusual Astronauts
Tardigrades, or water bears, are microscopic organisms that have been studied for years for their extreme resilience to potentially harmful conditions. They require a thin layer of water to do anything- eating, moving, reproducing, etc. They are found all over the Earth, however, including in some of the driest environments on the planet. They are […]

Europa’s Oceans & Aliens
In September of last year, the Hubble Space telescope observed what is believed to be plumes of water erupting from the surface of Jupiter’s moon, Europa. The surface of Europa is covered in a layer of ice of unknown thickness, and it is widely believed that there could be vast oceans of liquid water underneath […]

Nuclear Fusion Powering Earth
The core of the Sun is at such extreme temperature and pressure that in that core hydrogen atoms are constantly fusing into helium and giving off massive amounts of energy. The Sun fuses about 4.25 million metric tonnes of hydrogen every second, which provides a power generation of 3.8 x 10^26 watts. By contrast, the […]

The Oort Cloud
The Oort Cloud is a theorized “shell” of comets and other objects that are on the edge of our Solar System. It is much harder to observe than other objects in and around our solar system like the Kuiper Belt, so it’s existence is only theorized, but it is the best way for us to […]

Uranus’ Seasons
Typically when we think of seasons we think of those we experience on Earth, lasting around 3 months, and having unique characteristics as far as temperature and weather go. Things are a bit different on Uranus, due to a huge impact that the planet experienced billions of years ago. This impact knocked the axis of […]
