Coming Soon: Altair, one of the only stars apart from the Sun which has been directly imaged.

Tomorrow or more likely Monday Tueday, I'll return to the Star of the Week. This time I'll be writing about Altair, another member of the Summer Triangle. This star is of special interest because it has been directly imaged. This means that there is a picture of the surface of the star, not just some point in the sky. This was done with an instrument operated by my university which I hope to use in my own research! It turns out, moreover, that Altair is not a sphere. It spins so fast that it bulges.
