Blog #7: Sara Seager Ted Talk

I watched the 2015 Ted Talk from Sara Seager (of the Seager Equation) called The Search for Planets Beyond our Solar System. She sets out to introduce what we currently know about our solar galaxy and extra solar planets. She presents a few interesting artist conceptions of the various exoplanets we know of (mainly from […] Continue reading

My Journey toward Astronomy

As the course ASTR 2110 – Solar System calls to the end, I would like to write something about myself. I applied to Vanderbilt University in biomedical engineering, which was a very different subject from physics & astronomy. I started to be enthusiastic about physics and astronomy in childhood when staring into the infinite space […] Continue reading

Arecibo Message

Arecibo message is a radio message that carries information about humans to globular star cluster M13. It was famous for the coding of the message. The message included 1679 binaries, and two prime factors — 23 & 73. When aliens receive the message, they will easily put the signal to the 23 x 73 matrix […] Continue reading

All Things Must Come to an End

I’ll admit, at first when I had to go out observing I wasn’t thrilled at the idea of leaving my cozy dorm to walk a good 15 minutes to stare at the night sky. However when I got there and really had a chance to stop and really look at the sky and see the […] Continue reading

You Live There?

Before humans and animals and even plants dominated the Earth, it was full of prokaryotic life. Extremophiles are types of prokaryotes that can not only survive, but thrive in extreme environments. There are several types of extremophiles. Acidophiles: like acidic environments, (pH levels of 3 and below) Alkaliphiles: alkaline environments, and like pH levels 9 […] Continue reading

Using Fungus in Space?

There are a lot of barriers to humans living in space. But two of the problems may have an innovative solution involving fungus. A major problem is radiation. Once you get farther away from Earth, Earth’s atmosphere and magnetic field can no longer pro… Continue reading

Where Are the Aliens?

Based on various calculations and estimations made by scientists all over the world, there is a very high probability that aliens (i.e. life elsewhere in the universe) exist. However, we have never encountered any tangible or irrefutable evidence of aliens. This contradiction is called the Fermi Paradox. One possible explanation for this paradox is that […] Continue reading

Extremophiles

The word extremophile comes from the Latin words extremus (meaning extreme) and philia (meaning love). An extremophile is an organism with the ability to survive, or even thrive, in an environment that we as humans would consider extreme. These organisms are some of the oldest species to exist on Earth. Some of them date back […] Continue reading

What if life existed in every solar system?

The Drake equation investigates the likelihood of intelligent, communicating life existing on other worlds in our galaxy. But what if life could easily exist on other worlds, and there was life in every solar system around us? What could this potentially mean for us? First, we must consider the fact that the closest star to […] Continue reading

The Golden Record: A Message Sent to the Cosmos

In 1977, the Voyager I and Voyager II spacecrafts were launched into space to study the outer solar system. After conducting flybys of the planets in the outer solar systems, the Voyager spacecrafts continued to travel away from Earth, and will eventually travel out of our solar system. With this knowledge, golden records were placed […] Continue reading
