APOD: APOD Turns Eighteen (2013 Jun 16)

[Guest]

Happy 18th Birthday Astronomy Picture of the Day! You have been my home page ever since discovering you 16 years ago. My thanks to all who work so very hard in bringing APOD into my home. You are greatly appreciated. I have learned so much and have been able to see our universe through your eyes. Here's to experiencing glorious outer space and all its treasures together for many years to come!

[suzy Q]

Thank you everyone for bringing people all over the world together as one in this beautiful multi-verse, universe.

I sat at my desk at the Climate and Radiation Branch, searched for 'Astronomy' in Alta Vista and there you were. (circa June 20, 1995)

Still the best damn page on the 'Net —

BIG SHOUT OUT FOR YOUR BIRTHDAY!!! HERE IS TO YOUR NEXT EIGHTEEN, TOM.

How can one picture a day amount to over a billion picture in 18 years? You must miscalculate the number!
There's several orders of magnitude difference!

[NGC3314]

Wow - eighteen years! 1995 seems so long ago.

I am humbled to see that images credited to me, taken with equipment ranging from HST down to a 35mm camera using actual film, have shown up over the years something like 50 times (many in the early days when there was not the stiff and skilled "amateur" competition of today).

Keep it up, APOD folks, contributors, and Universe which is endlessly fascinating at all wavelengths!

Uh oh, one of your cronies? I dread the day we have a second Art running around the forum creating positive feedback loops with the first.

Hyppo Birdie Two Ewe APOD!!! )

You are my home page and so the first image I see when I open my laptop, you have awed me for years and I have seen every picture back to first one.

Some I return to fairly often, like the scale of the Universe video, the Everest 360 degree picture, and also the comparison images of the stars showing the Sun as a speck compared to Arcturus...

So, I wish you many many happy returns and hope to see many thousand more images from my beloved APOD...

Thank you Thank you Thank you for the fun and mind blowing images!!!

Love, Isabelle in Victoria Canada

Happy Birthday APOD, and thank you to everyone who has helped make APOD my first click of the day for over 13 years. Long may it show us the fabulous, awe-inspiring nature of our Universe. Hip! Hip! ...

[NWF]

APOD has been one of my daily essential pages for many years. Congratulations, well done, and while I might not be around in another 18 years, I certainly hope APOD will be.

Also, If you consider that many if not most of the images displayed as APOD's are either mosaics of numerous stitched images like the MARS panoramas and galactic center of over 2000 images

or stacked images like the analemma which combine 36 images

Click to view full size image

These types of images greatly increase the total image count though they are presented as a single image

Happiest of Birthdays APOD! Thank you for all the morning coffee breaks, all the science, all the humor, and, mostly, the innumerable things I know now that I did not know when you were 1!
