Pluto: from planet to dwarf planet
Pluto is one of the six dwarf planets that we have currently identified in our solar system, and it was the first object discovered in the Kuiper belt. It was discovered in 1930 and was initially declared to be the ninth planet. However, when other objects were discovered in the Kuiper belt (like the dwarf […] Continue reading

Space Junk
Now that humanity has reached a stage where we can send equipment and spacecraft to space quite frequently, there is a concern about the build-up of debris around the Earth. The Department of Defense keeps surveillance of more than 27,000 pieces of rogue debris that are orbiting within the near-Earth environment. These pieces of “space […] Continue reading
Mini Saturn Orbiting Saturn?
Perhaps the moon in Figure 1 looks like a miniature version of Saturn. Maybe even an empanada. Saturn’s innermost moon Pan was first identified in 1990 in a photograph captured by the Voyager 2 spacecraft (which flew in 1981). Pan has an average diameter of 17.6 miles and orbits about 83,000 miles apart from Saturn. […] Continue reading
Asteroid Mining
Rocky asteroids contain metals that are commonly used on Earth. What if there was a way to mine those metals from asteroids and bring them back to Earth? The potential gains seem promising, as even a small asteroid can contain enough industrial metals … Continue reading
Blog 6: Asteroids
On this Tuesday, April 5th, an asteroid the size of a house flew by the Earth. This asteroid flew by 79,000 miles away from us, which is actually pretty close. That distance is around 1/3 the distance between us and the Moon. Although there is always some panic that an asteroid could hit Earth, this […] Continue reading
Blog 5: Pluto
Pluto is a very weird, and unknown “mass”. Since being alive, our generation has known Pluto as the 9th planet of the solar system, and now as a giant rock, or dwarf planet. Despite this, Pluto has some very cool features that aren’t seen other places in the solar system, such as Ice Volcanos. Although […] Continue reading
Amateur Astronomer Discovers Jupiter’s 80th Moon
Amateur Astronomer Kai Ly used images from the Canada-France-Hawaii telescope taken in 2003 to identify a previously undiscovered Satellite orbiting Jupiter, the first planetary moon discovered by an amateur astronomer. The telescope used was the 3.6 meter Canada-France-Hawaii Telescope located on Mauna Kea. Ly used an image captured in February 2003 to identify a set […] Continue reading
Kepler-186f
Kepler-186f is an extrasolar planet that was discovered on July 23, 2015. It was the first rocky planet about the size of Earth found in the habitable zone. The habitable zone is an area around a star where the temperature is good for liquid water. Oth… Continue reading
You Can’t Sit With us
The famous used to be planet kicked out by none other than Neil deGrasse Tyson is now considered a dwarf planet, ever since 2006. Pluto was reclassified because it didn’t meet the three criteria the IUA uses to define a full sized planet Criteria Must orbit a star It must be big enough to have […] Continue reading
The Evolution of Earth’s Atmosphere
So many of Earth’s features today, from our blue sky to life itself, depend on the atmosphere surrounding the planet, but it has taken billions of years to evolve to where it is today. This post will explore the evolution and progression of Earth’s atmosphere as well as the processes that led to these changes. […] Continue reading
