Blog 5: Eris

Eris is a trans-Neptunian object and is the second-largest dwarf planet in the solar system. It was discovered in 2005. It is .28 % the mass of Earth. Eris has one large moon, Dsymonia.It is about  96 AU away from the sun. Its orbital period is 559 Years. Its surface has methane ice. This shows […] Continue reading

Interesting facts about Pluto and our path to exploring it

Dr. Alan Stern is most known for his role as the principal investigator of the New Horizons mission to explore Pluto and the Kuiper Belt. Recently, Dr. Stern spoke at Purdue University on October 10, 2019, discussing and examining the topic of “What If We Return to Pluto?” During this discussion, he detailed many interesting […] Continue reading

Detecting Extrasolar Planets

Extrasolar planets can be difficult to detect because they are tiny, far away, and dim, but the Doppler Method provides an indirect way to find them. This method involves looking for alternating blueshifts and redshifts in the star’s spectrum, which reveal a star’s motion around its center of mass. This motion could reveal the presence […] Continue reading

Kepler-16b – The Existence of Tatooine

Kepler-16b was discovered when looking for exoplanets using the transit method from the Kepler mission of 2011. While looking at this data two stars were discovered to be in orbiting each other due to the dip in brightness of the system when they eclipsed. What was strange was even when they were not eclipsing each […] Continue reading

Jupiter’s Magnetosphere

Jupiter’s magnetosphere is by far the strongest. This is because of how thick its layer of metallic hydrogen is and its high-speed rotation rate. Its strength is 20,000 times stronger than Earth’s. It’s so large that it begins to avert the solar wind almost 3 million kilometers before it even reaches Jupiter. Jupiter’s magnetosphere in…Continue reading » Continue reading

Jovian Layers

The formation of our solar system helps explain the composition of the Jovian planets. Past the frost line, hydrogen compounds condensed into ices. The four jovian planets started as icy planetismals, but Jupiter and Saturn captured much more hydrogen and helium gas than Uranus and Neptune during solar system formation. This is probably because Jupiter […] Continue reading

Black Holes: A great mystery of the universe

Black holes are one of the greatest mysteries of our universe. However, using just a few concepts that we have learned in class, we can understand the basic constructs of black holes. A black hole is the result of a single point in space containing extreme mass (this point is called a singularity). Similar to […] Continue reading

Blog 6: Planet Nine

Planet Nine is a hypothetical planet on the edge of the solar system. Its gravity would explain the weird orbit of objects beyond Neptune. It is predicted to be 5 times the size of Earth. It is assumed to be about 400- AU The Scientists who created this hypothesis believe that the star formed much […] Continue reading

blog post 06

In 2019, researchers captured the first image of a black hole. They were able to do this by having all the major radio telescopes on Earth act together to simulate a radio telescope that was the size of Earth. Before this, we could only see indirect evidence of the existence of black holes. This particular […] Continue reading

Hot Jupiters: Migration and Orbital Changes

Hot Jupiters are gas giants that have orbital periods that are very close to their stars; often less than 10 days. Usually this means they are less than 0.1AU away from their stars which is one tenth the distance between earth and the sun. While scientists originally did not think giant planets could exist this […] Continue reading
