Did you get a chance to watch the IYA Live Telescope Today? Our target was the extremely compact and bright globular cluster, M80 in the constellation of Scorpius. What a treat! Of course, if you didn’t get a chance to watch it live, we made sure to capture a quick video for you to share….
Messier 80 (also known as M80 or NGC 6093) is a globular cluster in the constellation Scorpius. It was discovered by Charles Messier in 1781.
M80 is located midway between Alpha Scorpii (Antares) and Beta Scorpii in a field in the Milky Way that is rich in nebulae. It can be viewed with modest amateur telescopes as a mottled ball of light. With an apparent diameter of about 10′ and at an estimated distance of 32,600 light-years, M80’s spatial diameter is about 95 light-years and contains several hundred thousand stars. It is among the more densely populated globular clusters in the Milky Way Galaxy. M80 contains a relatively large amount of blue stragglers, stars that appear to be much younger than the cluster itself. It is thought these stars have lost part of their outer layers due to close encounters with other cluster members or perhaps the result of collisions between stars in the dense cluster. Images from the Hubble Space Telescope have shown districts of very high blue straggler densities, suggesting that the center of the cluster is likely to have a very high capture and collision rate.
On May 21, 1860, a nova was discovered in M80 that attained a magnitude of +7.0. The nova, variable star designation T Scorpii, reached an absolute magnitude of -8.5, briefly outshining the entire cluster.
As always, you can join us whenever the skies are clear and dark in Central Victoria by clicking on the live remote cam link under the IYA telescope logo to your right. Have a great time!

Considering the great distance and extreme compactness of M 80, I think your televised view turned out rather well, similar to the view in a 4-6 inch telescope on a dark, steady night.
