Space is vast. In fact, vast enough to contains many million, billions, and trillions of galaxies and other celestial objects. So the ultimate question is, how do scientists keep track of all of the celestial bodies? How do we know that the Andromeda galaxy is coming toward us if we can’t tell if it is… 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

Just Because You’re Bulkier, Doesn’t Mean You Pull More

We’ve all seen and learned about the cosmos and the stars up above. We learned that the Earth revolves around the Sun because the Sun’s force on the Earth is greater than any of the other major celestial bodies near this. However, something that many people forget is that this process is facilitated by Newton’s Universal… Continue Reading → Continue reading

Red, White, and Blue: The Star Life Cycle

We’ve talked a bit about black body radiation and how some stars appear more reddish or bluish, or maybe even just white. But how  and why do stars appear as more reddish or bluish, and why are some stars larger than others? What makes Red Giants and White Dwarfs special? Well, it all has to … Continue reading Red, White, and Blue: The Star Life Cycle Continue reading
