Not all of these quizes are relevant, but some of them are helpful.
They're also a bit short.

Apod 2.2

This nebula, NGC 6164, was created by a rare O-type star, which was 40 times larger than the sun. The star in the center of this image is only 3 million years old. When the star's age doubles, it will explode and create a supernova explosion. The blue halo surrounding the star is caused by an earlier phase of the O star in the center.

APOD 2.3

This is a picture of some cosmic clouds inside the emission nebula IC 1805. The clouds have been modified and shaped by winds and radiation from stars in the star cluster Melotte 15, which is about 1.5 million years old. This nebula is 7,500 light years away from Earth.

Apod 2.1

This is a picture of a cosmic cloud inside the van den Bergh Catalog of stars surrounded by reflection nebulae. The blue color of the cloud is caused by the same process that gives Earth its blue skies. The catalog that contains this cloud is around 5 light years across.

Apod 1.8

This picture takes place inside of the Orion Nebula, which is approximately three-million years old. The cluster of four bright-blue stars in the center of this image is called The Trapezium. The circular shape the stars create has a radius of almost one and half light years. Recent studies lead to the idea that in its earlier years, the Orion Nebula formed a black hole that was 100 times more massive than our sun. If this study is confirmed, the Orion Nebula will house the closest black hole to Earth, which is 1500 light years away.

Apod 1.7

This is a picture of the horsehead nebula,also known as Barnard 33, which is part of Orion. It is part of a large molecular cloud. The nebula's odd shape was first recorded in the 1800s. The dark parts of the nebula are caused by dust and the reddish glow originates from hydrogen gas that has been ionzed by the star Sigma Orionis.
