Trip to Space

Average and Massive Main Sequence Stars

Come visit our sun! It lives in the main-sequence stage in its life. Scientists expect that it will live for 5 billion more years until it will turn into a red giant. The sun is only an average main-sequence star, meaning it is smaller than a massive main-sequence star.

Red Giants and Supergiants

This is a picture of a red super giant called Betelgeuse. On your trip, you will be able to see this star. This red super giant came from a massive main sequence star. After this, it will shed off all of its layers and turn into a supernova. You'd better hurry if you want to see this star as it is now!!

White Dwafs

White dwarfs are the leftover centers of an older star. These stars do not have any hydrogen left, because they are the leftovers, so they can not generate energy. They will shine for billions of years before dying out. So, even if we traveled by the speed of light, we would not be able to actually see one. We can only see it from afar.

Globular and Open Clusters

Clusters are groups of stars that, from afar, look like they are grouped together in clusters of stars. When you get closer to the clusters, you realize that they actually aren't very close together. A globular cluster can contain up to 1 million stars and looks like a tight ball. An open cluster does not look as tight as a globular cluster, but in comparison to the whole universe, they are close together. On your trip, you will not be dodging stars because they are all spread out closer and farther away from you.

Supernovas and Neutron Stars

A supernova is a giant explosion where a massive star collapses and throws its outer layers into space. Sometimes, these explosions can be so powerful and bright that they are brighter than an entire galaxy for several days.

Neutron Stars are stars that have collapsed under gravity to the point where electrons and protons have smashed together to form neutrons.
