Planets rich in carbon may be waterless worlds
Planets rich in carbon, including so-called diamond planets, may lack oceans, according to NASA-funded theoretical research. Our sun is a carbon-poor star, and as result, our planet Earth is made up largely of silicates, not carbon. Stars with much more carbon than the sun, on the other hand, are predicted to make planets chock full …

And did L.A. even deserve one of these precious birds? The answer to the questions posed all the way along became crystal …
Cassini swings high above Saturn to take a portrait

The observation and resulting image mosaic were planned as one of three images for Cassini’s 2013 Scientist for a Day essay contest. The contest challenges students to …
Top 10 must-see list for new astronomers
It is very difficult to draw up a Top 10 list in any subject. In astronomy it is even more difficult due the the huge number of prospective candidates for the list. I have made it somewhat easier by restricting the list to things that beginners may view with relatively basic equipment. My list is …
