In the Night Sky

Night Skies in August

 

Much has been happening in the science world at NASA toward the end of July. Everyday much is discovered and much is being done.

Cassini is preparing to send  the last details of Saturn before its last flight into yore. Every day we hope to uncover more of the past.

Whilst all this is happening, Juno is sending back more and more information to help us understand our Universe.

Closer to us there is a partial eclipse of the moon on the 7th. of August and a full solar eclipse on the 21st. of August. Sadly though, we will be able to view the partial lunar eclipse but not the solar eclipse. The American are estatic; this eclipse will be visible in totality within a band across the United States and only partially visible in other countries.

 

As there is not much time left of our winter season, before the rains and clouds hit us again; let us make use of as many dark nights as we can.

Clear star-filled nights to you all!
