The location will be centred in the interface. In the Aladin interface, you can search for both the popular name of an object (like "cartwheel galaxy") or known co-ordinates. Let's start our universal tour by searching for one of the most visually stunning galaxies out there, the Cartwheel Galaxy. Here we can scan the entire sky for hidden galaxies, and even decipher information about their stellar populations and evolution. Online view in Aladin Lite of the Cartwheel Galaxy in GALEX UV wavelengths.Īladin Lite is one of the greatest online tools available to look at our universe through the eyes of many different telescopes. In some cases human eyes will only ever look at what the computers have deemed is interesting! Massive amounts of data are hosted online, just waiting to be admired, for free. In the 21st century we have access to information any time, anywhere via the internet.Īutomatic telescopes and surveys now provide us with so much data we require machines to help us analyse it. Only a few decades ago astronomers had to tediously examine photographic plates after a long, cold and lonely night of observing. In just our observable universe we estimate there are over 2 trillion galaxies! I'm going to show you, though, how I get my fix of wonder by looking at galaxies that only a select few people will ever have seen, until now. A downside to this is that we don't always have that "hands-on" experience of looking at every square inch of the universe while we study it. In astronomy today, much of our work is handling enormous amounts of data by writing and running programs to work with images of the sky. ![]()
