The Milky Way is a barred spiral galaxy, which means it has a central bulge surrounded by spiral arms.

SDSS J1150+1122 is the largest known galaxy in the observable universe, with a diameter of approximately 2.3 million light-years.

The Sagittarius Dwarf Galaxy is the closest galaxy to the Milky Way, located approximately 16,000 light-years away.

A nebula is a cloud of gas and dust in space, often associated with the birth or death of stars.

The Orion Nebula is one of the brightest and most famous nebulae in the night sky, located in the constellation Orion.

Star formation is the process by which stars are born from the collapse of a cloud of gas and dust in a nebula.

Galaxies are much larger than nebulae and contain billions or trillions of stars, while nebulae are smaller and typically contain gas, dust, and young stars.

The Hubble Sequence is a classification system for galaxies based on their visual appearance and morphological characteristics.

Elliptical galaxies are the most common type of galaxy in the universe, characterized by their smooth, round or elliptical shape.

TON 618 is the largest known black hole in the universe, with a mass approximately 66 billion times that of the sun.

Gaia BH1 is the closest known black hole to Earth, located approximately 1,600 light-years away.

The event horizon of a black hole is the boundary beyond which nothing, not even light, can escape due to the immense gravitational pull.

Sagittarius A* is the name of the supermassive black hole at the center of the Milky Way.

The Event Horizon Telescope Image is the first image of a black hole ever captured, obtained by the Event Horizon Telescope collaboration in 2019.
