The Andromeda Galaxy

The Andromeda Galaxy is one of the only galaxies visible without the aid of a telescope on Earth. It is a spiral galaxy, and it got its name because it is located in the constellation Andromeda. It is approximately 2,480,000 light years from Earth and has a diameter of approximately 200,000 light years. The first […] Continue reading

The Andromeda Galaxy

Learn more about the future of our galaxy Most people know that we live in the Milky Way galaxy, however many people do not know that we also live close to another galaxy called the Andromeda Galaxy. While we learned about this galaxy in class, I thought that it was interesting to learn that the […] Continue reading

Blog 3 – The Great Collision

Right now, everything in our universe is getting further and further away from us. Except for one thing. That one thing is Andromeda, the closest galaxy to our Milky Way. Instead of getting further away, Andromeda is actually getting closer and closer. Right now, we are getting closer at a rate of 300 kilometers per … Continue reading Blog 3 – The Great Collision Continue reading

Putting the speed of light into perspective

The theory of special relativity tells us that there is an absolute speed limit in the universe, that being the speed of light. At a speed of about 300,000 km/s, light takes only one second to travel to the Moon from Earth and eight minutes to travel to the Sun from Earth. This speed is … Continue reading “Putting the speed of light into perspective” Continue reading

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

Consequences of a Constant Speed of Light

I find it fascinating that what we see in the night sky is an image from the past.  Since nothing moves faster than the speed of light it is impossible to know what is going on at this exact moment on places other than the Earth and the Moon.  Hypothetically, the Sun could suddenly explode […] Continue reading

The Vast Size and Scale of the Universe

Recently I saw this link on Facebook and I decided to check it out. I had no idea what I was in for. We have been talking about our galaxy and our nearest neighbor, The Andromeda Galaxy, a lot in class and this picture just released by NASA gives us a better idea of what exactly […] Continue reading
