| Tycho crater...the most explosive location on the lunar surface |
Guys...you are well aware of Tycho crater on the moon right? Yeahhhhhh that is not all about it...It has helped something to come onto the tv screens now. The thing is astronomers used it as mirror to see the planet Venus's transit around the Sun. We cannot directly focus our telescopes to the Sun due to its heat intensity. So the telescope is being focused at this crater Tycho which helps by capturing reflected sunlight and isolate the sunlight portion falling onto the Venus. So this is all the concept behind the scene. So now this whole technique has got so many applications like it can help us study the planet's physical and chemical atmosphere. Secondly the spectroscopy study is made possible by an arsenal of Hubble instruments, the Advanced
Camera for Surveys, Wide Field Camera 3, and Space Telescope Imaging
Spectrograph. The whole experiment will be carried out for 7 hours during the transit to get accurate wholesome observations.
I was really wondering why they are so focused at Venus's transit while there are hell lot more things to focus upon...may be now you are too ;-) Let me tell ya folks one thing...next transit will be at 2117...amazed? but its true...as we know the most important of the astronomical events occur very rare and this is one such!! So wishing the Hubble space telescope team a very good luck for this event, signing off for today.....
Yours Astro baby Pranu :-)
