The Subaru Telescope has made an exciting discovery: a small body beyond Pluto, with implications for the formation, evolution, and current structure of the outer solar system.
In the outer reaches of our solar system, far beyond the orbit of Pluto, lies Sedna, one of the most mysterious objects ever discovered. This reddish dwarf planet follows such an extreme orbit that it takes more than 11,000 ...
New evidence suggests that billions of years ago, a star may have passed very close to our solar system. As a result, thousands of smaller celestial bodies in the outer solar system outside Neptune's orbit were deflected ...
The Kuiper Belt, the vast region at the edge of our solar system populated by countless icy objects, is a treasure trove of scientific discoveries. The detection and characterization of Kuiper Belt Objects (KBOs), sometimes ...
A 7.6-meter (25-foot) whale died on a beach in northern France on Monday, hours after being discovered washed up and alive but wounded, authorities said.
Astronomers have searched for extraterrestrial civilizations in planetary systems for sixty years, to no avail. In the paper published by International Journal of Astrobiology, Cambridge University Press, and titled "Migrating ...
The solar system has eight planets. In 2006, astronomers reclassified Pluto as a dwarf planet, the same class that contains Eris, Sedna, Quaoar, Ceres and perhaps many more solar system small bodies. These are defined approximately ...
Object 90377 Sedna—a distant trans-Neptunian object known best for its highly elliptical, 11,390-year long orbit—is currently on its way toward perihelion (its closest approach to the sun) in 2076. After that, Sedna will ...
A team of astronomers, including associate professor Chad Trujillo of Northern Arizona University's Department of Astronomy and Planetary Science, have confirmed a planetoid that is almost four times farther from the Sun ...
Beyond the orbit of Neptune, a diverse collection of thousands of dwarf planets and other relatively small objects dwells in a region called the Kuiper Belt. These often-pristine leftovers from our solar system's days of ...
