The Big Bang
The Big bang occured from a random vacuum fluctuation and eventualy that created matter and energy with it. Scientists theorize that this is the beggining of the universe -
Afterglow
The afterglow of the big bang occured around when the universe was 370,000 years old. It is defined as the stage at which matter started forming when all the energy cooled. It helps scientists know the true age of the universe today. -
Dark Ages
It was a time that existed before the very first stars and galaxies. It is supposed to be traced to our origins that brought the first stars and heavy elements that we have today. It also helps understand how old the universe is a bit better. -
Formation of stars
The formation of the first stars begun approximately 13.3 billion years ago. It happenend because all the energy from the big bang cooled to form numerous stars. Stars have significant importance in astronomy due to the nature of them and what they can create or destroy. -
Creation of galaxies
Gravity starts to pull cosmic gas together to form galaxies. These galaxies also form what astronomers call clusters. Galaxies are probably one of the most important topics in astronomy. Basically because they can tie into other topics as well including: Black holes, stars, planets, moons, etc. -
Birth of the Sun
The sun now forms from a cloud of gas in a spiral arm of the Milky Way. It is created through massive amounts of fusion. All this occured five billion years ago scientists say, the sun also helps us have an understanding of other stars. -
Today
13.8 Billion years after the big bang life on earth has flourished. The universe is also said to be expanding at a very fast rate. Scientists can now trace our origins with a better understanding of the universe thanks to todays technology. -

The Hypernova of Eta Carinae
Hypernova Eta Carinae is affecting our part of the galaxy. It is said that even gamma radiation from this explostion could effect our planet. This is just one of many disasters in space that scientists study, but we have not yet have seen an actual supernove since a couple hundred years ago. -
VY Canis Majoris
VY Canis Majoris, now believed to be the second biggest star ever, is a red hypergiant and explodes. In turn produces one of the largest supernovas that galaxy has ever seen. The biggest stars throughout history have changed periodically and scientists will probably find a star that is bigger than NML Cygni. -
Constellations
Constellations that we know today will eventually be out of site in the future and will be replaced by constellations that we have never seen before. Constellations have been studied through human history and have been used for many explanations or life events. -
The Saggatarius dwarf galaxy
The Saggatarius dwarf galaxy will eventually merge with our own galaxy. It is said that it has been orbiting around our galaxy for quite some time. Scientists can pinpoint how and when this will happen and have done the same for many other merging galaxies. -
The Andromeda Galaxy
The Andromeda Galaxy will merge with our galaxy in 3800000000 years. It is currently 2.5 million light years away from earth and is traveling at speeds up to 250,000 miles per hour. Scientists have said that the Andromeda might have merged with another galaxy a while ago. -
The Virgo Supercluster
100,000,000,000 years later a new supercluster will form. This cluster will be so old that it will converge into one big galaxy. Even our clutster is included in this massive object. Clusters in general have added new information on what seems to be an endless universe. -
The Black Hole era
10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years later in the future black holes and very small particles will be the only things left in the universe. That alone is a very significant scientific discovery. -
The Dark Era
The Dark Era of the universe will occur Beyond 10^100. This almost nothingness of the universe will be composed of photons, neutrinos, electrons and positrons. Nothing else will happen, well at least that we know of.
