Blog 1: We Are All So Small!

Posted on February 14, 2017 by terranojm

Space is such a fascinating thing. There is just so much out there beyond our planet: so much we know about and even more we don’t know about! Growing up in school, we all learned about the solar system. As a result, we concluded that maybe our world isn’t the center of the universe like we may have … Continue reading “Blog 1: We Are All So Small!” Continue reading →

The Fermi Paradox

Posted on April 30, 2016 by alecsolarsystem

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 […] Continue reading →

The Crab Nebula

Posted on April 10, 2016 by astr2110geoffren

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 […] Continue reading →

Supermassive Black Holes

Posted on April 10, 2016 by 2016spaceodyssey

Astronomers have recently discovered a supermassive black hole in a region of space that is sparsely populated.  The black hole is 17 billion times bigger than the Sun (by mass), making it one of the larger black holes ever discovered.  The strange part is that scientists had only ever found supermassive black holes at the […] Continue reading →

The Mystery of “Hot Jupiters”

Posted on April 6, 2016 by alecsolarsystem

Over the last decade, astronomers have discovered thousands of exoplanets, many of which have gone against our current understanding of planet formation. Most of these exoplanets orbit very close to their star, as these are the easiest to discover since they block out more light from their respective stars than planets orbiting farther out do. […] Continue reading →

Many Different Milky Ways

Posted on February 16, 2016 by briannagalgano

We know that there are many different types of light in the Universe. Each type gives us unique information about the object we are studying. The above picture from NASA contrasts the same celestial object, the Milky Way, in different wavelengths. Note that the further we deviate on either side (longer or shorter wavelength), the […] Continue reading →
