1 00:00:00,500 --> 00:00:04,604 If all of our astrophysical objects or anything that we’re looking at 2 00:00:04,838 --> 00:00:07,640 were made up of one element, this would just be so easy. 3 00:00:09,142 --> 00:00:09,809 But we don’t. 4 00:00:10,310 --> 00:00:13,279 So we have to do experiments on Earth like this 5 00:00:13,279 --> 00:00:14,381 to prove 6 00:00:14,748 --> 00:00:17,650 what we’re looking at looks like what we are thinking we’re looking at. 7 00:00:17,717 --> 00:00:21,388 So, in here is argon. 8 00:00:21,388 --> 00:00:22,689 If we turn it on here ... 9 00:00:23,857 --> 00:00:25,825 it glows this really pretty purple 10 00:00:25,825 --> 00:00:28,928 and then, if we look at it with a spectroscope, 11 00:00:30,296 --> 00:00:33,466 it shows us a very specific fingerprint 12 00:00:33,600 --> 00:00:35,135 to argon. |
