The Large Magellanic Cloud (LMC) is the southern sky’s greatest celestial wonder. It is the Milky Way’s biggest satellite galaxy, just 160,000 light-years distant, The LMC is an easy naked-eye object even from mildly light-polluted areas,  It  lies primarily in the far-southern constellation Dorado the Swordfish, but some of it spills over into the neighboring constellation Mensa the Table Mountain, which lies even farther south.

A quasi-star is a hypothetical type of extremely massive and luminous star that may have existed early in the history of the Universe. Unlike modern stars, which are powered by nuclear fusion in their cores, a quasi-star's energy would come from material falling into a black hole at its core

The Cartwheel Galaxy is a lenticular ring galaxy about 500 million light-years away in the constellation Sculptor. It has a D₂₅ isophotal diameter of 44.23 kiloparsecs, and a mass of about 2.9–4.8 × 10⁹ solar masses; its outer ring has a circular velocity of 217 km/s. It was discovered by Fritz Zwicky in 1941.

Supernova; The Conclusion of Supermassive Stars

As a massive star burns through its fuel and begins to cool, the outward forces of pressure drop. When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds. This collapse produces the explosion we call a supernova.

A planetary nebula is a region of cosmic gas and dust formed from the cast-off outer layers of a dying star. Despite their name, the planetary nebula has nothing to do with planets.

The Milky Way is a spiral galaxy consisting of several hundred billion stars, Our solar system is located on the inner edge of a spiral arm, That is 25,000 light-years from the centre of the galaxy, which is in the direction of the constellation Sagittarius.

The Milky Way galaxy is just one of the billions of galaxies in the universe.
The universe is a vast expanse of space that contains all of everything in existence. It contains all of the galaxies, stars, and planets. The exact size of the universe is unknown but the scientists believe the universe is still expanding outward.
