Comets? Asteroids? Or what?
One of the most basic questions driving Astronomy and Space Exploration is: Where did the water […]

Mosaic image showing Saturn backlit by the Sun, one of the most beautiful photographs sent back by Cassini. Image Credit: NASA/JPL-Caltech/Space Science Institute
The origin of Saturn’s rings has been one of the most interesting puzzles in planetary science, and now new data from the Cassini spacecraft is helping to fill in the pieces, showing […]
An artist’s impression of Eris, the most massive dwarf planet known to date, with an aphelion of 97 AU from the Sun. Could bigger Super-Earth-type planets be orbiting even farther out? Image Credit: ESO/L. Calçada and Nick Risinger
Just like the proverbial cat with nine lives, the notion of an unseen planet orbiting […]
The discovery images of 2012 VP113. Three images of the night sky, each taken about two hours apart, were combined into one. The first image was artificially colored red, the second green, and the third blue. 2012 VP113 moved between each image as seen by the red, green, and blue dots. The background stars […]
A Hubble Space Telescope image of Pluto and some of its moons. The New Horizons mission is just a year away from providing us with photographs that will greatly surpass the best images of Pluto that Hubble could ever capture. Image Credit: NASA, ESA, H. Weaver (JHU/APL), A. Stern (SwRI), and the HST Pluto […]
