Not sleepy today? Go out and look south. There is a nice conjunction of Moon and Mars. along with Jupiter and Saturn nearby. Not every day you get to see this …
Check out Tvashtar volcano on Io seen spewing molten material into space, as seen from New Horizons probe in 2007. Io experiences massive tidal forces from Jupiter’s gravity and this kind of volcanic eruption is not uncommon for Jovian moons. For a sense of scale, the volcanic plume is about 330 Km in altitude. New Horizon was built by John Hopkins Applied Phyisics Lab for a mission to Pluto. This photo was taken when it flew past Jupiter for a slingshot course correction towards Pluto.
A partial solar eclipse is going to occur on Oct 3rd, 2014 and unfortunately will not be visible from India. Skywtchers in the United States Mexico and Canada are going to be able to witness this event. The maximum of the eclipse is expected at 9:45pm UTC
The eclipse will make a good photo shoot event with Venus in the background
A total Lunar Eclipse will occur on Oct 8th 2014.The penumbral phase begins at 8:15:33 UTC during broad daylight in India. Moonrise in Delhi will occur at 5:14 IST ( 11:44 UTC ) when the moon will be phase past the U3 umbral-penumbral contact. That means that the maximum extent of the eclipse would be over by the time the moon is visible. However stargazers in India may be able to see the partial phase which will extend into the sunset. The moon will finally come out of the umbral shadow at 7:03 pm ( 13:33 UTC )
Mark your calendars folks, its surya-grahana time in India again. Come July 2009 the moon will eclipse the sun as seen from India, Bhutan,Bangladesh,China, Japan and the Marshall Islands. Its going to be the longest solar eclipse for over a century and guess what, this time the path of totality passes through India. This eclipse pass over India comes after almost a decade. The last two eclipses happened in 1999 and 1995.
The eclipse begins on the 22nd of July 2009 at around 5:30 am IST in India and spends almost two hours passing the subcontinent. The path of totality will pass through central India passing over Surat, Ujjain, Baroda, Bhopal, Patna, Darjeeling, and Dibrugarh in the far east. Rest assured the Bohemians will be out there somewhere chasing the eclipse.!!!!

Eclipse Safety : Observing Eclipse Do”s and Don”ts
Before we go on I must warn you to NEVER EVER look at the sun especially the PARTIAL PHASE through unprotected eyes or homebrewn filtering mechanisms.
The use of homebrewn filters is recommended to seasoned astronomers only who understand the risks involved! There are however very simple ways to observe an eclipse without putting your eyes in harm”s way
One of the simplest method to observe the sun safely is through a pinhole projection camera. This can be used for viewing the partial phases of the eclipse. During totality however, it is perfectly safe to watch the eclipse naked eye.
To learn how to make a pinhole camera CLICK HERE
Alternatively you may use a solar filter
The first thing you must remember is that the human eye has no nerve endings, so if you burn your retina, it will not hurt. 😛 , which is all the more reason that caution is advised while observing the sun
It is never safe to look at a partial or annular eclipse, or the partial phases of a total solar eclipse, without the proper equipment and techniques. Even when 99% of the Sun”s surface (the photosphere) is obscured during the partial phases of a solar eclipse. This is primarily because nearing totality the ambient light levels become so less that our pupils dilate and the iris tries to allow in more light into the eye.
During the partial phase any surge in sunlight, like the one seen during a diamond ring formation can cause excessive solar radiation entering the eye and causing a burn on the retina.
In spite of these precautions, the total phase of an eclipse can and should be viewed without any filters whatsoever. The naked eye view of totality is not only completely safe, it is truly breathtaking
