The Fermi Paradox
As Arthur C. Clarke once famously said, “Two possibilities exist. Either we are alone in the universe or we are not. Both are equally terrifying.” This quote is relates in a very basic way to the Fermi Paradox. The paradox is that through the Drake Equation and the sheer size of the universe, there should […]

What’s Next?
Wow. In these last few months, we have gone over the entire cosmic calendar. The last topic of the class, life elsewhere in the universe, covered stuff that hasn’t even happened on this calendar yet. In this class, I really believe I’ve learned a lot of material, rather than memorizing a lot. Studying for this upcoming… More What’s Next?

A ~Record~ of Life on Earth
Before sending the Voyager spacecraft off into space in 1977, Carl Sagan and his team insisted on including a “bottle” to send off into the “cosmic ocean.” This message to potential intelligent life in the universe is contained in the Voyager record, a 12 inch golden record meant to encapsulate life on Earth. The record […]

The Chicxulub crater is a crater buried underneath the Yucatan Peninsula which is suspected to be the location of the impact of the meteor which wiped out the dinosaurs. The crater is more than 180km in diameter and 20km in depth. Estimates place the size of the impacting meteor to be at least 10km in […]

The Crab Nebula
When a star dies, it goes supernova and shoots everything that it was once made of across space. The explosion that formed the Crab Nebula was first documented by the Chinese in 1054 AD. Though, you didn’t need to be an astronomer to recognize the explosion or its resulting nebula. The Crab Nebula was visible for […]

North Korean Space Program’s Latest Breakthrough in Propulsion Technology!
Look out NASA, there’s a new kid on the block, and he’s got a shiny new toy.

The Demise of Pluto
Left: Pluto Demoted, Right: Size Comparison The discovery of Pluto had scientists ecstatic. Far out in the distance was this tiny, freezing, icy planet with moons! Then it was official: Pluto must be added to the list of planets. It’s round, orbits the Sun and has a posse of moons, what more could we need? […]

What’s in a Name?
The Hubble telescopes famous successor was not always called the James Webb Space Telescope (JWST). The telescope, initially dubbed the Next Generation Space Telescope, was rechristened in 2002 to pay homage to the celebrated James Webb, NASA’s second administrator. Webb ran NASA from 1961-1968, a time when the emergent agency was still trying to define […]

Let’s Talk About Carl Sagan (Remix)
“If you wish to make an apple pie from scratch, you must first invent the universe.” These are the only words I really remember of Carl Sagan’s Cosmos series when I watched it in high school physics class. However, Carl Sagan left a much greater legacy than his musings on apple pie. Carl Sagan inspired an […]
