UY Scuti, the biggest known star, viewed through a telescope!

  • #1

Main Question or Discussion Point

I have been appointed the project manager at Rutherfurd Observatory, and was thus granted access to use the primary telescope. I spent 2 days trying to locate UY Scuti and finally, I've did it!

For those who don't know what UY Scuti, it's the biggest known star in the universe. If it were to be replaced with the Sun in our solar system, it'd extend beyond the boundary of Saturn.

Here's a cheeky peek at our big-boy UY Scuti (the brightest star in the middle):

That's a pretty bold claim, since we know next to nothing about our own Milky Way galaxy, let alone the millions of other galaxies which are visible.

I am NOT saying that UY Scuti is the largest star in the entire universe, I am saying that UY Scuti is the largest star discovered yet. It has a median radius of 1,708 solar radii, or approximately 7.94 AU.

Fun fact: The majority of the star's volume is composed of a gas that is less dense than most of the Earth's atmosphere.
