There may be, but the jury is out at this point.

How do humans know if they haven't explored the universe yet? At present, it is only the observation of the "observable universe".

The universe is a vast and mysterious existence, containing countless galaxies. There are many galaxies that have been discovered, and some of the important ones include the following types:1
Elliptical galaxies: Elliptical galaxies usually appear elliptical or nearly spherical in shape and do not have a distinct spiral structure. The interior of their galaxies is mostly made up of aging stars, and one of the most well-known elliptical galaxies is the Andromeda Galaxy.
2.Spiral galaxies: Spiral galaxies often have a distinct structure of spiral arms that rotate around the central core region.
The Milky Way galaxy in which we live is a typical spiral galaxy. And the Andromeda galaxy (also known as M31) is another famous spiral galaxy. 3.
Irregular galaxies: Irregular galaxies are galaxies that do not have a well-defined symmetrical structure, usually caused by the irregular distribution of interstellar matter. The distribution of stars and interstellar matter in these galaxies is relatively chaotic.
The Great Magellanic Galaxy is a typical irregular star Void Orange System. 4.Ellipse-spiral galaxies:
This type of galaxy is somewhere between elliptical and spiral galaxies, and has the characteristics of the central core region of elliptical cluster galaxies and some spiral structures. They are a relatively rare type of astral system, but they still exist in the universe. In addition, there are other special types of galaxies, such as starburst galaxies, active galactic nuclei, and galaxy clusters.
A galaxy cluster is a huge structure formed by the gravitational pull of many galaxies on each other, containing thousands of galaxies. It is important to note that the galaxies we know so far are only the tip of the iceberg, and there are still tens of billions of galaxies in the universe waiting to be explored. Future scientific research will continue to reveal more galaxies and their properties, expanding our understanding of the universe.

1. Common galaxies are divided into the following types: elliptical galaxies, hat galaxies, spiral galaxies, lenticular galaxies and irregular galaxies. The Milky Way is a typical spiral galaxy, and our solar system is on the spiral arm of Orion, the third vortex of the Milky Way.
2. At present, there are as many as 125 billion galaxies that can be observed by humans, and there are many that we cannot observe at present.
3. It is understood that the Laniakea Supercluster, where our Milky Way is located, contains about 100,000 galaxies, with a range of about 100 million parsecs (100 million light-years).
4. Galaxies, also known as cosmic islands, are derived from the Greek word galaxias). In a broad sense, galaxies refer to the operating systems composed of countless galaxies and dust. Referring to the Milky Way, it is a large galaxy containing stars, gas, cosmic dust, and dark silver matter, and is bound by gravity.
5. Typical galaxies, ranging from dwarf galaxies with only tens of millions of stars to elliptical galaxies with trillions of stars, all orbit around the center of mass. With the exception of individual stars and thin interstellar matter, most galaxies have a large number of star systems, star clusters, and a variety of different nebulae.
There are about 5 billion extragalactic galaxies that have been discovered, and together with our own Milky Way, collectively known as total galaxies, represent all the cosmic ranges that humans have come into contact with so far. But the universe itself is infinite and expanding, so there should be an infinite number of extragalactic galaxies that we don't yet know. There is no exact number of how many galaxies there are in the universe, some say more than 80 billion, some say more than 100 billion, some say 1000 200 billion. >>>More
Towards the end of the 18th century, Messier completed the Messier Catalogue, which included 103 bright nebulae. Soon after, William Herzell completed a catalogue of up to 5,000 nebulae. In 1845, Lord Ross built a new telescope capable of distinguishing between elliptical and spiral galaxies, and he also found some independent points in these nebulae, providing evidence for Kant's earlier claims. >>>More
It is generally believed to be a spiral galaxy.
Spiral galaxies are the most numerous and beautiful galaxies ever observed. Its shape resembles a whirlpool in a river, hence its name. >>>More
A spaceship, or spaceship, is a single-use spacecraft that transports astronauts and supplies to space and back safely. There are also space shuttles that have flown many times. It transports astronauts to live on the space station for a short period of time and perform certain jobs. >>>More
