European-Extremely Large Telescope

The European Southern Observatory began construction of the European-Extremely Large Telescope (E-ELT) back in 2014. This telescope is on track to be the world’s largest optical and infrared telescope by the time it is completed in 2024, thus living up to its name. The E-ELT will include a main mirror that is 128 feet in … Continue reading “European-Extremely Large Telescope” Continue reading

Blog Post #3: The Great Attractor

Ever since Edwin Hubble’s groundbreaking observations, it has been known that the universe is expanding. According to his observations, galaxies farther away from us are moving faster than objects closer to us (at least in terms of relative velocities). However, according to more recent studies, the Milky Way and other galaxies near us seem to … Continue reading Blog Post #3: The Great Attractor Continue reading

First Galaxies Formed Today

…according to the cosmic calendar. The cosmic calendar is a visualization method to help comprehend the age of the universe. This calendar puts the beginning of the universe at the start of the first of January, and the end of December 31st at our current point in time.

Andromeda and the Size of the Universe

  In 2015, Hubble was able to take the most detailed image of Andromeda ever taken. The image had a pixel density of 69.536×22,230 pixels. The picture was taken using 7398 exposures. Images like this really put into light how vast the universe is. In the video, they focus in on a shot of the … Continue reading Andromeda and the Size of the Universe Continue reading

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

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

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

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
