Science Behind the News: Impacts on Jupiter

submitted by: nsf

The impact of comets on the surface of Jupiter are a fairly common experience. At the University of Central Florida, astronomers Joseph Harrington and Csaba Palotai are leading a project that studies precisely how these impacts happen, and also provides valuable information about what might happen if such a comet struck Earth.

Science Behind the News: Extrasolar Planets

submitted by: nsf

Extrasolar planets, or exoplanets, are planets that orbit stars other than our sun. Astronomers like Dr. William Welsh at San Diego State University primarily use two methods to detect these distant planets: Doppler and Transit methods.

Science Nation - Super Stars

submitted by: nsf
Who are the biggest super stars in the universe? For Adam Burrows, an astrophysics professor at Princeton University, it's not who, but "what," and they are far from Hollywood, or even earth, for that matter. Burrows would tell you biggest super stars are the stars that die in a massive explosion called a "supernova." With support from the National Science Foundation, Burrows investigates supernovae and he has recently created 3D computer simulations showing the actual moment of a star's...

SDSU Geological Sciences Webinar - Gary Peterson

submitted by: tcarrasc
The Enigmatic Satellites of Saturn Gary Peterson Professor Emeritus Department of Geological Sciences San Diego State University Saturn, everyone's favorite planet, is the second-largest of the outer giant gas planets and has the lowest density (0.7) of any planet. The others gas planets are about 1.5. In addition, Saturn has the largest satellite (Titan) in the Solar System. Titan is about the same size as Mercury of the inner Solar System. How can this be? It is suggested that...

Resonance: Radio, Wineglasses, Opera Singers and Cycles

submitted by: RayTomes
Resonance is the quality of transmitting even tiny signals between systems that are tuned to the same frequency. Given that cycles of common period are found pervading many different disciplines, perhaps an explanation may be found in resonance. An example is the 160 minute (and associated 80 minute cycle) cycle, found in biological systems, outer planetary spacings, the rotation rates of planets, asteroids and binary stars, solar oscillation and flux and galactic cores. A cosmic pervading...

Harmonic Cloud Patterns on Jupiter

submitted by: RayTomes

Regularly spaced clouds appear in Jupiter's belts, sometimes white spots and sometimes swirling waves. A polar projection of Jupiter, made by NASA from the 2000 flyby, allows accurate testing of the hypothesis that these waves form as predicted by the Harmonics Theory. It is found that expected strong harmonics 12, 24 and 72 are present.
