| Top 10 New Discoveries in Space |
Space has always been a subject of fascination for humans. Since the beginning of civilization, we have looked up at the stars and wondered what lies beyond. With the advancement of technology and exploration, we have made remarkable discoveries in space. In this article, we will discuss the top 10 new discoveries in space.

1. Gravitational Waves
One of the most significant discoveries of our time is the detection of gravitational waves. In 2015, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected ripples in the fabric of space-time caused by the merger of two black holes. This discovery confirmed Einstein's theory of relativity and opened up new avenues for studying the universe.

2. Proxima b
In 2016, astronomers discovered an Earth-like planet orbiting the nearest star to our solar system, Proxima Centauri. The planet, named Proxima b, is in the habitable zone of the star, which means that it has the potential to support life.

3. Trappist-1 System
In 2017, NASA announced the discovery of seven Earth-sized planets orbiting a red dwarf star, Trappist-1. Three of these planets are in the habitable zone, making them prime candidates for hosting life. This discovery has renewed our hope of finding life beyond our solar system.

4. Oumuamua
In 2017, astronomers detected an interstellar object passing through our solar system. Named Oumuamua, the object was the first known visitor from another star system. Its unusual shape and trajectory have sparked debates among scientists about its origins and nature.

5. Dark Matter
Scientists have long theorized about the existence of dark matter, a mysterious substance that makes up most of the matter in the universe. In 2018, the European Space Agency's Gaia mission provided the most detailed map of the Milky Way galaxy, which revealed the distribution of dark matter in our galaxy.

6. Fast Radio Bursts
Fast radio bursts are intense bursts of radio waves that last only a few milliseconds. In 2019, astronomers detected the first fast radio burst originating from a galaxy 500 million light-years away. These bursts are still a mystery, but they could be signals from extraterrestrial civilizations.

7. Black Hole Image
In 2019, astronomers captured the first-ever image of a black hole. The image was captured by the Event Horizon Telescope, which is a network of eight radio telescopes around the world. The black hole in the image is located in the center of the galaxy M87 and has a mass of 6.5 billion times that of the sun.

8. Phosphine on Venus
In 2020, scientists detected the presence of phosphine gas in the atmosphere of Venus. Phosphine is a potential sign of life, and its presence on Venus has sparked new interest in exploring the planet for signs of life.

9. Martian Water
- Scientists have long suspected that there is water on Mars, and in 2020, they finally found concrete evidence. NASA's Mars Reconnaissance Orbiter detected a lake of liquid water under the south pole of Mars. This discovery has significant implications for the search for life on the red planet.
. ______________________________ .
10. Supermassive Black Hole Collision
In 2020, scientists detected the collision of two supermassive black holes, each with a mass of over 800 million suns. The collision resulted in the formation of an even larger black hole, which is now one of the most massive objects in the universe.
