The wildcards that are supported and their How do I get started in astronomy data analysis? Simbad is useful for figuring out an object’s designation because it gives you a listing of object cross references, making it easier to figure out just what you are looking at.

In this case you can’t see the other member of the pair in the image, but you can do further research using Wikipedia for example to find out that the other member is NGC 941. Enter NGC 936 and click “SIMBAD search” to bring up the result.

Is it possible to build an efficient Electric Vehicle engine with minimal to no computing control systems? Continuing from What is the impact of an exposed secret key for a JWT token implementation? The numbers at the top of the image are the Right Ascension and Declination of where the cross hairs are on the image. From this cockpit picture I cannot identify this aircraft. Properties of z ~ 3-6 Lyman break galaxies. The interface to Simbad isn’t all that user-friendly, making it look rather intimidating to use at first, but it’s actually straightforward to use once you know what to do.

This tutorial walks you through quickly researching an object. astroquery.simbad.SimbadClass.reset_votable_fields(). Simbad provides another way to access its database via TAP query.

This is useful if you want to query a known identifier. I explain how to use Aladin in another tutorial where I show you how to investigate your own images using Aladin.
