Why Two Types of Planets?

FIGURE 8.5 from The Cosmic Perspective (taken from Quizlet) When looking at a diagram of our solar system, one likely notices that there are two visually distinct categories of planets. The smaller, rocky planets—Mercury, Venus, Earth, and Mars—are known as the terrestrial (Earth-like) planets, and the larger, more gaseous planets—Jupiter, Saturn, Uranus, and Neptune—are known […] Continue reading

Geology of Mars

Mars has a fascinating geology that is very comparable to Earth in many ways and also shows its very dynamic history. A well known geological feature on Mars is Olympus Mons, the largest volcano in the solar system, which stands at a height of approximately 16 miles and spans 374 miles in diameter. To compare, […] Continue reading

Geology of the Moon and Mercury – Blog 4

After writing my last blog post about atmospheres and the greenhouse effect, when learning that the atmospheres of the Moon and Mercury cause them to be considered practically airless and have no weather, I became heavily intrigued. What makes the Moon and Mercury so different from the other planets in our solar system? Thus, I […] Continue reading

Atmospheres and the Greenhouse Effect – Cameron Klein

When I used to think of planets, the planets’ atmospheres were typically the last things that would cross my mind. However, a planet’s atmosphere is a defining feature of it’s qualities. To start off, what even is an atmosphere? An atmosphere is a layer of gas that surrounds a planet (or planetary body) that is […] Continue reading

Blog 8 – The History of Venus

When asked to picture Venus, many of us picture a hot, volcanic, inhabitable place — and we would be correct. However, science suggests that it may not have always been this way. A study of five different climate simulations of Venus found that in each of these scenarios, the planet could have supported liquid water […] Continue reading

Blog #6: Detecting Extrasolar Planets

The photo above features the transit method of detecting extrasolar planets. Detecting extrasolar planets is a very delicate and challenging task for scientists. The distances between stars and relative sizes of stars compared to planets make it extremely hard to pick them out. Stars are also typically a billion times brighter than planets. There are […] Continue reading

The Loneliness of Rovers

Throughout this semester in ASTR2110, I have been reminded about how small we are compared to the universe. While this can be both a deflating and motivating perspective on our approach to astronomical study, I think it is undeniable that the rovers on Mars are unimaginably lonely during their stints on the red planet. I […] Continue reading

The Atmosphere as we know it

The atmosphere is split into four different layers: the troposphere, the stratosphere, the thermosphere, and the exosphere. The troposphere is the lowest layer and is where greenhouse gasses absorb the infrared light and where storms occur. The stratosphere absorbs solar ultraviolet light by ozone, Earth is the only planet to have this layer. The thermosphere […] Continue reading

A Climate in Crisis

For this post, I’d like to increase my understanding of global warming because the book introduced to me the major process behind it. First off, I’d like to acknowledge that the climate crisis truly is one of the most difficult things we have globe have faced. We began on this Earth as a species tossed […] Continue reading

We Come in Peace! (If you can Find Us)

It’s a common theme for me within this class to fixate on the possibility of life beyond Earth, and I’m glad to do that once again with today’s blog post. I want to respond to the book’s claim that life on Mars is an “extraordinary claim”. While it’s true the bold assertion like the one […] Continue reading
