A Quote by Sir Martin Rees, Astronomer Royal of Great Britain



Telescopes are in some ways like time machines...
They reveal galaxies so far away that their light has taken billions of years to reach us. We in astronomy have an advantage in studying the universe, in that we can actually see the past. We owe our existence to stars, because they make the atoms of which we are formed. So if you are romantic you can say we are literally starstuff. If you're less romantic you can say we're the nuclear waste from the fuel that makes stars shine. We've made so many advances in our understanding. A few centuries ago, the pioneer navigators learnt the size and shape of our Earth, and the layout of the continents. We are now just learning the dimensions and ingredients of our entire cosmoc, and can at last make some sense of our cosmic habitat.

Tragic loss - in memory of Neil Armstrong!


In memory of a legend who passes away today. I decided to write this post for Neil Armstrong (82). For a man who is so famous, that his name is still studied, and will be studied in the future, by children all over the world. A man who in everybody's eyes is a hero and the frontier of space exploration, lived such a normal and simple life. Thought I should share some interesting facts about him (Courtesy:TOI)

1. After flying combat missions during the Korean War, he became a test pilot and joined Nasa's astronaut program in 1962. 

2. As he stepped on the moon's dusty surface, Armstrong said: "That's one small step for a man, one giant leap for mankind." obviously we all knew this about him from our good old text books.

3. Armstrong's pulse was measured at 150 beats per minute as he guided the lunar lander to the moon's surface, Nasa said. Asked about his experience on the moon, he told CBS: "It's an interesting place to be. I recommend it." 

4. In 2005 Armstrong was upset to learn that his barber had sold clippings of his hair to a collector for $3,000. The man who bought the hair refused to return it, saying he was adding it to his collection of locks from Abraham Lincoln, Napoleon, Marilyn Monroe, Albert Einstein and others. 

5. Despite his quiet nature, Armstrong once appeared in a television commercial for the US automaker Chrysler. He said he made the ad because of Chrysler's engineering history and his desire to help the company out of financial troubles.

I meant to upload this video (http://youtu.be/gkCxJ4hUhv8) on youtube for a very long time, but I lazy'ed it until today. Maybe it was meant to be for this day. I thought I should atleast do this much for a man who did so much for Mankind. RIP Neil Armstrong. You will be remembered.

One crazy fact about Curiosity's landing on Mars!

Definitely a major milestone in Space exploration. Let me start here by congratulating NASA.

Just in case you did not know:
1. It takes 14 minutes for the signal from the Rover to reach Earth.
2. It takes approximately 7 minutes for the Rover to land on Mars after it touches the Mars atmosphere.

Here goes the crazy fact: By the time, we, on Earth, get the signal from the rover that it has touched the Mars atmosphere, the rover has already landed safely or got destructed somewhere!!

Everything was automatic, with no chance for course correction. With more than 500,000 lines of code and Zero margin of error... Absolutely phenomenal !!

Check out some cool videos on the NASA website:

Moon, like never seen before

Great to be back to write about one of the most photographed object in the night sky... our good old Moon. This video that I saw on space.com is stunning.. so stunning that I HAD to post it..

Staring at the moon for hours together when I was a kid..beautiful! Looking through my telescope at the craters and the shadow formations, imagining the mountains..awesome! But nothing matches what you will see in this video. The more I look at this video.. the more I want to look at it. Okay, enough said, have at it...
 Now here is the best part.. This is no Artists imagination... its all real, up close videos and images taken by Nasa's LRO. Be on the look out for more of these, astro enthusiasts.

UARS set for a glorious self destruction

As UARS (Upper Atmosphere Research Satellite) reaches its end of a productive 6 years of research, the world awaits its glorious self destruction as it enters earth's atmosphere on Sep 23rd 2011. It is supposed to enter the Earths atmosphere US time on the 23rd but the exact location is still unknown. As it burns itself while entering the atmosphere, scientists say, it can glow as bright as Venus. Hope to get a glimpse of this historic event.


As Sep 23rd is getting close, NASA is getting a clearer picture as to where this doomed satellite will enter earths atmosphere. Feel free to visit this page for the latest info. http://www.nasa.gov/mission_pages/uars/index.html

Below you can see an Artists image of how it might look from up above.
I am from Southern California and maybe I am too optimistic, but wish it enters on the west coast and falls in the Pacific Ocean. Its will be a beautiful site to see.


Fingers crossed.

My first Astro image.

For an amateur astronomer, it’s an Amazing feeling to take my first astro image! I have been trying to take a picture of the moon for quite some time now. Finally I have some success. Believe me guys it’s a treat.

It took me a few months to figure out what the problem was. It was a focal length issue and the webcam image sensor was not able to reach the focal point of my Zhumell 10 inch. I took out the image sensor from the webcam and placed it half way into the eyepiece hole. Luckily, the hole was big enough to accommodate the image circuitry. I taped this arrangement inside the eyepiece to avoid any disturbances. With little adjustments to the eyepiece focusing...BAM! I had the image of the moon.

So for guys who are trying to take a picture of the moon with a webcam and you see that your image is blurry no matter what you do.. You know it’s a focal length issue. Just try to do what I did above and you should be able to get a view. I used wxAstrocapture to record an AVI file and then used Registax 6 to process the image. I know that there are tons of images of the moon out there... but for me this image will always be special.
My first astro image! A processed file.




Specifications of the instruments used:
A Zhumell 10 inch dobsonian (No equitorial mount)
A logitech webcam (CCD sensor, non moded)
and A laptop :)

Many more images to follow...

Meteor Lights Up Georgia Sky

A Man-Size Meteor From Comet Lit Up Georgia Sky yesterday...
The 6-foot-wide (1.8-meter) space rock barrelled into Earth's atmosphere at 10:47 p.m. EDT on May 20 (0247 GMT on May 21), about 66 miles (106 kilometers) above the city of Macon, Ga. Two NASA all-sky cameras, both located in northwest Georgia, tracked the resulting meteor and captured it on video.

Just a thought though!

All of this is cool.. But we have advanced so much in space technology that NASA should be able to build a "go getter" space shuttle that goes outside of earths atmosphere, breaks down the meteor and gets a part of the meteor safely down to earth. I am sure that there would have been an era of space history lost when the meteor burned down to ashes, when it entered earths atmosphere.

Yesh.
