New SDSS-III sky survey is now available on WikiSky

We have added sky images from latest data release of Sloan Digital Sky Survey – SDSS-III DR8

The release contains all of the imaging data taken by the SDSS imaging camera, now covering 1/3 of the whole sky (over 14,000 square degrees out of 41,253 square degrees of whole sky)
In addition all existing images from previous data releases have been rebuilt with higher quality. The imaging survey contains about a million fields 3 mega pixels each, that totals to 3 Terra pixels of imaging data.
Latest release is available as “SDSS-III DR8″ from “DSS” menu on front page. It also replaces DR7 survey for default “SDSS” survey id in direct link, i.e. Previous DR7 is available using “SDSS7″ survey id: as We still working on some image defects cleanup. New update will be available shortly.

We’ve received several requests from our users for ability to invert colors of sky map images for printing purpose. You can now find “Negative” checkbox on our snapshot tool page.

Due to constantly growing visitors traffic to our resource and growing amount of data available on sky-map our existing servers reached its capacities and require a serious upgrade. We have opened fundraiser campaign. Please read this page for details. We would appreciate any help. Thank you!

  3. Considering your visitors data exhibited at the bottom of this page, 743 all time simultaneous visitors on 3/7/2011, I question the wisdom of spending $14K to upgrade your servers. Is it possible to show a map like the one for cpu usage on pcs? How many simultaneous visitors will the new servers support? Just curious.

    Those numbers are blog visitors only, that is less than 1 percent of total sky map visitors. Our servers handle up to 25000 requests per minute. About 5-10% of those requests require expensive in terms of CPU cycles real-time image projection generation. At rush hours CPU graph is solid at 100% on all servers. New servers will handle up to 100K requests per minute plus additional space will allow us to add more data and services.

  5. Hi there just wanted to give you a quick heads up. The words in your content seem to be running off the screen in Ie. I’m not sure if this is a formatting issue or something to do with internet browser compatibility but I thought I’d post to let you know. The design and style look great though! Hope you get the problem fixed soon. Cheers

    I think everything posted was very reasonable. But, think about this, what if you
    were to write a awesome headline? I mean, I don’t want
    to tell you how to run your website, but what if you
    added something that grabbed a person’s attention? I mean New SDSS-III sky survey is now available on WikiSky |

    SKY-MAP.ORG / WIKISKY is a little vanilla. You might look at Yahoo’s front page and note how they create post headlines to grab people to open the links.

    You might add a video or a picture or two to get readers excited about
    what you’ve written. In my opinion, it might bring your blog a little livelier.
