A new Stellar Catalog

A new two-year long study done by the European Space Agency has created the most comprehensive survey of the universe ever recorded. The Gaia project has cataloged over 1.7 billion stars, 14,000 asteroids and numerous galaxies and galaxy clusters spread throughout the universe. What started out as a relatively small affair eventually exploded into a … Continue reading A new Stellar Catalog Continue reading Continue reading

The Fermi Bubbles

The Milky Way is a flat disk, and if you put into human perspective it’s about the same proportion of a stack of 4 DVD’s. Putting it… Read more “The Fermi Bubbles” Continue reading Continue reading

Missing Dark Matter

There is an understanding that about 80 percent of the mass in the universe is made up of material that we cannot observe, and that matter is called dark matter. Although there is no direct evidence of dark matter, it must be present to hold the elements of the universe together. Recently, it was discovered … Continue reading Missing Dark Matter Continue reading Continue reading

A Greedy, Gluttonous Galaxy

It’s no secret that the universe is growing. However, research leads us to believe that our own Milky Way Galaxy is growing as well. In fact, our galaxy exhibits cannibalistic behavior, absorbing material from the dwarf galaxies surrounding it. We know that the chemical makeup in the central bulge of our galaxy differs from the … Continue reading “A Greedy, Gluttonous Galaxy” Continue reading Continue reading

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 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 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. In this demonstration model, January 22nd (today!) … Continue reading First Galaxies Formed Today Continue reading Continue reading

Blog 1: We Are All So Small!

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 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 Continue reading
