Stargazers' Calendar April 2012
Don't Miss The Night Sky's Highlights
April night sky offers many hours of delight for all stargazers.
Surely you don't want to miss the oldest known meteor shower, or the best Saturn has to offer...
Lets take a look at some stargazing highlights this month...
Hot Flow Anomalies Are Amazing Phenomenon On Venus
Hot flow anomalies release so much energy that the solar wind is deflected, and can even move back toward the Sun.
Thatís a lot of energy when you consider that the solar wind is supersonic, traveling faster than the speed of sound and the HFA is strong enough
to make it turn around.
As the solar wind flows around Venus, it creates similar space weather effects as it does near Earth, but rememeber that Venus has no protective
magnetic field, so the explosion happens right above the surface of the planet!
New Kepler Explorer:
View The 1,790 Distant Planetary Systems - For Free!
Armchair explorers of the cosmos can now have at their fingertips the nearly 2,000 distant planetary systems discovered by NASA's Kepler Mission.
Now available for free from the iTunes App Store, Kepler Explorer was developed through the OpenLab initiative at UC Santa Cruz,
which brought together faculty and students in astrophysics, art, and technology for a summer institute last year.
Bright Star In The Constellation Lyra Is Cooler Than The Human Body
The coldest class of stars have temperatures as cool as the human body.
Astronomers hunted these dark orbs, termed Y dwarfs, for more than a decade without success.
When viewed with a visible-light telescope, they are nearly impossible to see.
The Wandering Stars
In ancient civilizations, people pondered the meanings of the stars, watching for clues to their survival: the beginning of planting and
harvesting times, the seasons, and even portents of danger.
They soon noticed that certain stars didn't stay in place, but wandered amongst the fixed star field.
