Speed of light and distance
It is a nearly universal maxim of science fiction that faster than light (FTL) travel must exist. Let us take a look at why this is universally necessary for the sake of a good story by comparing the size and scope of both our real universe and a few fictional universes to how long traversalContinue reading “Speed of light and distance” Continue reading
The Revolutionary Hubble Legacy Field
This past spring I interned at a company that developed educational documentaries about interesting topics such as nature, history, and space. The owner of this company had a history of creating planetarium footage, and he managed a successful YouTube channel called SpaceRip. This channel compiles fascinating footage of our solar system and explains many ofContinue reading “The Revolutionary Hubble Legacy Field” Continue reading
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

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
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
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

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
