Doctor Who is not COMPLETELY fictional

Image from wikipedia.com This article covers arguably one of my favorite topics to swoon over-Doctor Who.  I will be completely honest in saying that my intense interest in studying the solar system and beyond came pretty much single-handedly from watching Doctor Who (and maybe a teensy bit by my mom making me watch old Star […] Continue reading Continue reading

Some pretty extreme(“ophiles”)

Image from wikipedia.com That above picture is of a water bear, one of multiple really cool extremophiles discussed in this article.  The article makes a really cool comment about how we are lucky that water bears, and the same probably holds true for other extremophiles as well, are so small.  Otherwise, it is likely that […] Continue reading Continue reading

Io’s crazy volcanoes!

photo from space.com So, we all know that Io is notoriously the volcanic moon of Jupiter, but apparently a couple of years ago it randomly got…MORE volcanic? According to this article, in August of 2013 three large eruptions occurred on Io.  To put it in perspective, this is the number of large eruptions that we […] Continue reading Continue reading

A trip to Venus?

video from phys.org It seems like all of the talk in the field of space travel these days has been too focused on a trip to one single location…Mars.  But noticing while studying these past few chapters that Venus is actually a bit closer to Earth than Mars, that brought up a question in my […] Continue reading Continue reading

Weight is just a number!

picture from storejpg.com Weight IS just a number-it’s simply the product of the mass of an object and the force put on that object due to gravity!  Since the number is dependent on gravity, it’s totally logical that, since the force of gravity from the Sun is different in different locations in the Solar system […] Continue reading Continue reading

The first navigational tool

Image from kaloujm.com People have been using the sky as their source of navigation for years, and one of the first tools made for the purpose of aiding in navigation (that wasn’t a body part!) was the kamal.  The exact date is unsure, but it’s estimated that this tool came into use around the fifth […] Continue reading Continue reading

During this time Kepler developed his three laws of planetary motion, […] Continue reading Continue reading

The oldest recorded solar eclipse!

After talking about solar eclipses in class yesterday, I got super nerd-ily excited about reading more about them!  A quick wikipedia search (since that is totally acceptable and awesome!) links to tons more wikipedia pages that list the exact date, time, type, location, and path width, among other details.  The oldest recorded one listed on […] Continue reading Continue reading

William Herschel believes in ghosts!

picture from: www.redorbit.com One of my favorite moments in the Neil deGrasse Tyson-hosted show Cosmos: A Spacetime Odyssey takes place in the first moments of one of the first few episodes.  It “flashes back” to the early 1800’s, showing a cartoon involving the famous astronomer William Herschel and his young son, John, walking along the […] Continue reading Continue reading
