In the 21st century, the understanding of the universe has vastly improved with nearly 6000 confirmed exoplanets discovered since 1990. Missions have explored various celestial bodies, revealing complex chemical compositions. Notably, Uranus and Neptune, the smallest gas giants, have not been closely studied since the Voyager 2 flyby in the late 1980s. These planets are similar to many of the discovered mini-Neptunes, which are speculated to potentially harbor life. The upcoming year 2034 presents an opportunity for future missions to study these unexplored worlds more closely.
In the 21st century, we have confirmed nearly 6000 exoplanets, compared to none in 1990, revealing a vast potential for life beyond Earth in the universe.
Uranus and Neptune, the smallest gas giants in our Solar System, remain unvisited since Voyager 2’s flyby in the late 1980s, warranting closer study.
