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Although the moon’s tectonic plates are no longer active, the moon does experience “moonquakes” not due to tectonic plates.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 […] Continue reading

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… Continue reading

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 […] Continue reading

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 […] Continue reading

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 […] Continue reading

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 […] Continue reading

What if Earth stopped spinning?

*Warning: rather long documentary!* I’ll sum up the documentary, but suggest you watch if you have time. In essence, a slowing Earth result in an orbit where the length of the day is equal to the entire year. Long exposure to the sun, and long exposure to space at night would result in extreme temperature […] Continue reading

The Formation of the Universe

This video is one of the coolest things I’ve watched in a while. We’ve talked a lot in class about the formation of the universe and while it all seems to make sense, the scale (of both size and time) are not easy to wrap your head around. What makes this video so cool is […] Continue reading
