Rosetta’s Trajectory

This photo found on NASA’s Solar Exploration page diagrams the trajectory for the European Space Agency’s mission Rosetta’s exploration of the comet 67P/Churyumov-Gerasimenko. Launched in 2004, Rosetta has since flown-by Earth three times, Mars, and two asteroids, and is scheduled to arrive at the comet later this year.  It’s so how cool scientist are ale […] Continue reading Continue reading

Observing the Night Sky

The website Sky and Telescope is very cool! It shows an easy to understand layout of what planets, stars, etc. you will be viewing in the night sky and where they will be moving throughout the night and week. It also gives you categories of different celestial objects you can try to search for in […] Continue reading Continue reading

Orion Nebula

Nebulae have always been one of my favorite parts of the universe. I like how this video goes into detail about what makes up the Orion Nebula. It’s so hard to believe that we have the technology to discover so much about something so far away. It’s hard to imagine that the four main stars […] Continue reading Continue reading

Formation of the Solar System

I have always been a fan of Stephen Hawking. In this video, he does a great job of explaining the formation of the solar system beginning with the origins of the universe. From the Big Bang and how the explosion of an ancient star spread out all the elements generated from its life and death […] Continue reading Continue reading

Spectroscopy

I always wondered how we were able to determine what chemicals are present in other stars in outer space. This video excellently and concisely teaches the basics behind studying this in terms of spectroscopy. Naturally, light is important in our viewing of the stars, but I never considered that the way different elements bend light […] Continue reading Continue reading

Tides

This video is a cool, informative, easy understand animation of how the gravitational pull between the Earth and the Moon affect tides. It clearly and concisely describes how tidal forces cause high tides twice per day even though the moon is only overhead once per day and why the gravity is weaker at a greater […] Continue reading Continue reading

Historical Astronomers in Context

Tycho Brahe Born December 14, 1546; Died October 24, 1601 Brahe’s contributions to astronomy were based on observations he was able to make despite not having access to a telescope.  He was able to map put planetary motion, which helped in the development of the current model of the solar system.  He had observed a […] Continue reading Continue reading

Neil Armstrong

Admittedly, I had pinned this image on my Pinterest a while back. I think it is so fascinating and really puts the whole scale of our world and the universe into perspective. Neil Armstrong had the insane privilege to view the Earth in a way the no other human, animal, insect has been able to. […] Continue reading Continue reading
