The Solar System is located in the Milky Way Galaxy, a barred spiral galaxy with a diameter of about 100,000 light-years.

The Milky Way Galaxy is a barred spiral galaxy, which means it has a central bulge, a disk, and spiral arms.

The Milky Way Galaxy is estimated to contain between 100 and 400 billion stars.

The Milky Way Galaxy is located in the Virgo Supercluster, which is one of the largest superclusters in the Universe.

The estimated age of the Universe is 13.8 billion years, based on measurements of the cosmic microwave background radiation.

The Big Bang Theory is the prevailing cosmological model for the Universe from the earliest known periods through its present expansion and cooling.

The shape of the Universe is currently believed to be flat, meaning that parallel lines remain parallel and the angles of a triangle add up to 180 degrees.

The Heat Death is the hypothetical state of the Universe in which the Universe has reached its maximum entropy and there is no free energy left for work to be done.

The Hercules-Corona Borealis Great Wall is the largest known structure in the Universe, stretching for over 10 billion light-years.

The Andromeda Galaxy is the closest major galaxy to the Milky Way Galaxy, located about 2.5 million light-years away.

The Local Group is a group of galaxies that contains the Milky Way Galaxy and the Andromeda Galaxy, among others.

The Local Group is estimated to contain between 30 and 100 galaxies, with the Milky Way Galaxy and the Andromeda Galaxy being the two largest.

The Local Group is located in the Virgo Supercluster, which is one of the largest superclusters in the Universe.

The observable Universe is estimated to be about 93 billion light-years in diameter.

The Big Bang Theory is the prevailing cosmological model for the Universe from the earliest known periods through its present expansion and cooling.
