Some of the smallest moons in the solar system hide in the rings of the giant planets. But when it comes to a system of rings as dirty and dark as Uranus, it can be harder to find these moonlets than it is at Saturn.
Since arriving at Jupiter on July 4, the Juno spacecraft has had a chance to see some of the giant planet's fireworks up close and personal.
It has been brought to the Daily Gazette's attention that on Monday night, Swarthmore student P. Siphi was working late on an astronomy project in the observatory, when they picked up a strange transmission that overrode the music that they were ...
Using statistical analysis and scientific computing, Astronomers at Western University have charted a path that most likely pinpoints the very origins of comet 67P/Churyumov-Gerasimenko, which is vital information in discovering what kind of material ...
X-rays from the radio galaxy 3C31 (blue), located 240 million light-years from Earth in the constellation of Pisces, allow Astronomers to probe the density, temperature, and pressure of this galaxy, long known to be a powerful emitter of radio waves.
This unique property not only ensures a spectacular sight when viewed through a sophisticated instrument attached to a telescope such as Hubble's Advanced Camera for Surveys (ACS), but gives Astronomers a cosmic laboratory in which to study the ...
On Monday, beginning at 6:30 p.m. Craig Nance, Superintendent of McDonald Observatory at the University of Texas, will be the special guest lecturer for the Tallahassee Astronomical Society's (TAS) monthly meeting at the Challenger Learning Center.
