The Pelican Nebula is an emission nebula that spans 10 light years and forms the shape of a pelicans head. This closeup of the nebula was formed by compiling data from emmission spectra data from sulfur hydrogen and oxygen atoms to red green and blue. The dark regions are cold clouds of dust and gas whose shapes were formed by the radiation of young stars. The two jets erupting from the nebula are signs of proto stars forming in the nebula

This gassy nebula located 6,500 lightyears away towards Cassiopeia, is an area with lots of new star formation. The Dust in this nebula is so thick, that it had to be imaged with infared and scientifically recolored. The red areas are areas of heated gas, while the green and white areas are locations of much higher density. The collision of these different regions of gas form pillars of hot, dense gas; which is prefect for star formation. W5 is shown in this image, and when viewed along side IC 1805 they are called the heart and soul nebula.

M83 is a Spiral galaxy 12 million lightyears away, in the Hydra constilation. This compound image was formed by combining images previously found on the Hubble Legacy Archive. The unique combination of dust and young stars in its spirals has led to this galaxy receiving the nickname 'The southern Pinwheel' for its resemblance to a pinwheel. The blue areas are regions of young stars, and the red regions are areas of star formation. Not only is the center full of old stars, but when viewed in the x-ray spectrum it is very bright, which means it is also full of neutron stars and black holes.
This image is of the NGC 3628 Galaxy is of its side. This galaxy is 35 million light years away. Affectionately referred to as the Hamburger Galaxy, it can be seen in the Leo constellation. The flairs that can be seen at any of the wider points of the galaxy were likely caused by gravitational interaction with other galaxies. The outside portion of this system consists almost entirely of young blue stars, as can be seen by the color of the outermost star cloud. This image was taken using deep space image technologies.

Went outside for like 6 hours and looked at the sky, saw a lot of stars and constellations aquila pagasus andromida, other near by stuff. triangle. Looked at the sky and found the meaning of life, but i forgot it. I wish there was more to look at in the fall sky, looking forward to the winter sky though! Hopefully it'll be as cool as it is every year!
