REMINDER

The Asteroid Arrives Tonight
The largest close-approaching asteroid on record-will sweep closest to Earth tonight November 8, 2011 at 5:28 p.m. CST (23:28 UTC).

About a quarter mile wide (400 meters)-round and dark-2005 YU55

will be 198,000 miles (319,000 kilometers) from Earth’s surface.

It will be closer than the orbit of the moon.

What will it look like? Will you see it as it sweeps past?

*********************************************************************************************************

HOWEVER
This asteroid will come within 200,000 miles

(319,000 kilometers)

from Earth,

and although it is a large asteroid, it is small in contrast

to the Earth or moon.

Thus it will be faint – too faint to see with the eye alone.

You will need at least a 6-inch telescope to see it.

That said, this post provides two charts from Sky & Telescope magazine that should help you find the asteroid, if you do have telescopic aid.

I include here a static image of Jupiter and it's soundscape,

and a stunning sky time-lapse.
 

JUPITER NASA-VOYAGER SPACE SOUNDS (1990) BRAIN/MIND RESEARCH
Fascinating recording of Jupiter sounds (electromagnetic "voices") by NASA-Voyager. The complex interactions of charged electromagnetic particles

from the solar wind , planetary magnetosphere etc. create vibration "soundscapes". Jupiter is mostly composed of hydrogen and helium. The entire planet is made of gas, with no solid surface under the atmosphere. The pressures and temperatures deep in Jupiter are so high that gases form a gradual transition into liquids which are gradually compressed into a metallic "plasma" in which the molecules have been stripped of their outer electrons. The winds of Jupiter are a thousand metres per second relative to the rotating interior. Jupiter's magnetic field is four thousand times stronger than Earth's, and is tipped by 11° degrees of axis spin. This causes the magnetic field to wobble, which has a profound effect on trapped electronically charged particles. This plasma of charged particles is accelerated beyond the magnetosphere of Jupiter to speeds of tens of thousands of kilometres per second.

It is these magnetic particle vibrations which

generate some of the sound you hear on the recording.
