Moonquakes
Although the moon’s tectonic plates are no longer active, the moon does experience “moonquakes” not due to tectonic plates. There are four types of “moonquakes”, which can generally be explained by non-tectonic factors: tidal forces, meteoric impacts, and “the expansion of the frigid crust when first illuminated by the morning sun after two weeks of … Continue reading Moonquakes → Continue reading

Our Place in the Universe
When Carl Sagan requested that NASA redirect its Voyager 1 camera towards Earth from the edge of the Solar System, he knew that it would be of little scientific value. The image taken, “Pale Blue Dot” proved to be one of the most iconic and powerful space photographs ever taken. The sheer magnitude of space […]

Hot off the Press: Enceladus’ Heated Core
Recent findings suggest that Enceladus, the sixth-largest of Saturn’s 62 satellites, may have heats of up to 190 degrees Celsius in its interior. NASA’s Cassini Spacecraft encountered dust particles near Saturn which originated from Enceladus. Instruments on the spacecraft found that the particles were high in silicon, but lacking in metals like sodium and magnesium. The University of … Continue reading Hot off the Press: Enceladus’ Heated Core → Continue reading

Stonehenge: A Place of Death
Stonehenge, found in England’s Salisbury plain, is thought by many to be a calendar of sorts that tracked the movement of the Sun. But through my research I found out a few things about Stonehenge that would surprise anyone. First of all, Stonehenge took 3 million man hours to create and was built over the…

Potential Ocean Underneath Jupiter’s Surface
Scientists using the Hubble Space Telescope have found out that there is an ocean beneath the surface of Jupiter’s largest moon, Ganymede. According to NASA officials, this ocean that is buried under a thick crust of ice may hold more water than the collective amount of water on Earth. Scientists think the ocean is 10 […]

Signs of Warm Water Found on Enceladus
NASA’s spacecraft, Cassini, has made an astonishing discovery about one of Saturn’s moons, Enceladus. This spacecraft has entered Saturn’s orbit and is sending information to the space center about Saturn and its moons. The purpose of sending this spacecraft was to make an effort of finding another celestial body that have habitable traits similar to […]

The K-T Extinction: Asteroids and Atmospheres
Let’s talk about the dinosaurs. Everyone has heard the story: Dinosaurs roamed the Earth ages ago until an asteroid hit and caused all of them to go extinct. There was a huge amount of dust thrown up into the atmosphere which blocked out the Sun and caused plants to die. This set off a chain […]

It’s All in the Rocks
As many people know, rocks are broken up into three main categories: igneous, metamorphic, and sedimentary. However, the formation processes that govern why one would find a certain type in a certain place is very important to exploration of activity of a terrestrial world. Let’s start with igneous rocks. These are rocks that cool directly […]
