Cup of Tea anyone?

The constellation of Sagittarius is rich with interesting objects. Not to mention it is also where a big Black Hole lives! Don't worry, we're not going to be pulled in and even if we are, we wouldn't actually know anything until it's too late!

So what makes this part of the sky so interesting? Part of the constellation is a group of stars that form the shape of a teapot.

Along the spout of the teapot, if you can imagine steam coming out as it boils, you will find 4 distinct different nebula.

Today, we are going to take a look at the Trifid and Lagoon nebula.

Let's start with the Lagoon Nebula (M8). This is an emission nebula and is approximately 5000 or so light years from where you are currently standing. Within this emission nebula, new stars are forming and lighting up the surrounding gases by ionizing the photons. This amazing nebula gives off colors of both red and blue. Using a filter, you will notice more nebulosity of varying red shades.

If you point your telescope towards this object, you will see what looks like an open cluster of stars. If your seeing this, you are in the right place!

Just above the Lagoon Nebula lies the Trifid Nebula (M20). Similar to the Lagoon Nebula, it too is an emission nebula made up of ionized gases. Specifically what is known as H II or H2. This nebula gained its name because of the shape. The word trifid means divided into 3. What makes this nebula so interesting is that just above it is a reflection nebula. The near by stars light are reflecting off interstellar dust giving it a bright blue glow.

The area of space within the Trifid Nebula is also an open cluster of stars. Interestingly enough, the nebula also has something called a dark nebula. This dark nebula obscures the light from out perspective which is what makes the emission nebula look like it is divided into 3 sections.

This area of space is a constant birthing ground of new stars and upon closer inspection, you can see the stellar nurseries of the stars forming with what look like columns.

There are more things in this area of the sky including the Eagle Nebula, home to the pillars of creation and the Omega Nebula, a massive star making factory!

If you would like to see some of these objects in space, why not join the LGSCV on a night out and look at cool things in the sky!

Don't forget to bring yourself a nice cup of tea!
