If you are looking for a website to find all the details of the Universe in which we live, you cannot miss the existing one in legacysurvey.
DESI Legacy Imaging Surveys is producing a catalog of models from a data set of optical and infrared images, comprising 14,000 degrees of extragalactic sky visible from the Northern Hemisphere in three optical bands and four infrared bands.
The result can be seen in this link, where we can lose ourselves among an immense amount of content with a coverage of the sky approximately delimited by -18 to +84 in celestial coordinates and | b | > 18 in galactic coordinates
To achieve this goal, DESI Legacy Imaging Surveys is carrying out 3 imaging projects on different telescopes.
Data Release 9 (DR9) is Legacy Surveys’ ninth public data release. It is the seventh public release of image and catalog data and the fourth release of BASS and MzLS data.
It is important to note that DR9 does not contain significant new observations, but builds on DR8 by improving the reduction techniques and procedures used. Legacy Surveys images are first zoomed through the NOIRLab Community Pipeline before being processed, so what we see on the web is a processed result, not what the telescopes see directly.
The Legacy Survey Sky Viewer The one I’ve linked to before is generally intuitive, but here are some additional features to get the most out of it:
– Every time we reload the page, jump to a new random NGC galaxy. – We can jump to a new random galaxy by entering a blank string in the Jump to object search box. – When clicking on the map, a pop-up window will appear with a few different options. One particularly useful option is Link Here, which redirects the browser to a URL that should reproduce what we are viewing, in the correct position, zoom, and layer, with the correct overlays enabled. RA, Dec coordinates, you can enter a RA, Dec number and zoom to see what we want. – If we select a layer and then select a second layer, we can go back to the previous layer using the space bar.
An excellent website to better know where we are.
