Here are the Editor's Picks articles for the Astronomy Site! These are the top ten articles that your Astronomy Editor feels are most important for you to read. Enjoy!
1. Copernicus - His Life
The day job of Nicolaus Copernicus, the reluctant revolutionary, was canon of a cathedral. The last resting place of this man who turned astronomy on its head was unmarked. How did his student astronomy books help to identify his remains four and a half centuries later?
2. Copernicus - the Revolution
In the 16th century everyone knew that Earth was the center of the cosmos. But this made it impossible to predict the motions of heavenly bodies, even if they moved in elaborate circles within circles. Copernicus turned the idea on its head and put the Sun at the center. A revolution had begun!
3. Meteor or Meteorite & Other Posers
What's the difference between a meteor, a meteorite and a meteoroid? Is one of them the same as a shooting star? And what about asteroids and planetoids - which one is a minor planet? If any of these terms have puzzled you, here is a guide to help you out.
4. Pluto Is a Dwarf Planet
Some people are still upset that Pluto isn't considered a planet any more. But was it ever really a planet?
5. Eris and Pluto - They're not Twins
For nearly ninety years Pluto was our ninth planet. Then in 2006, much to the annoyance of some, it was no longer a planet, but a dwarf planet. What happened? Eris happened. Some call Eris and Pluto twin planets, but they aren't twins. Eris has a secret.
6. Astronomy Humor
Here’s a collection of astronomy jokes for kids, adults and geeks of all ages. Laughter helps to keep us young and healthy, so see if anything tickles your fancy. (And how *does* the Man in the Moon cut his hair?)
7. Quasar Facts for Kids
Quasars are the brightest and most distant objects in the universe. And when we see them we are looking into the past, to a time even before our Sun and Solar System existed.
8. Northern Lights Planetarium
Tromsø, far to the north of Norway, attracts summer visitors to see the midnight sun and winter visitors to see the aurora borealis. The Northern Lights Planetarium is the northermost planetarium in the world. It's worth a visit at anytime, but extra welcome if it's too cloudy to see the sky.
9. Jupiter's Galilean Moons
Four moons circling Jupiter. It was a sensation when Galileo discovered them in the early 17th century - and they're still sensational! One is bigger than a planet. Another seethes with volcanic activity and has mountains taller than Everest. And which one has ocean that could harbor life?
10. Volcanoes - Fire and Ice
A volcano can produce a fiery sky with ash and deadly gases. The biggest one on Earth is Mauna Loa, but it's dwarfed by Olympus Mons on Mars which is three times the height of Everest. There are many volcanoes in the Solar System, including ice volcanoes.
