According to a scientific journal named Nature, there are unknown planets lurking within our Solar System. These hidden celestial bodies could range in size from Mars to even larger than Earth. The existence of these undiscovered planets was inferred through the observation of unusual field patterns in objects near the Kuiper Belt, which is a region beyond Neptune that contains icy bodies. The researchers believe that these anomalies are caused by the gravitational pull of massive hidden planets.

In addition to this intriguing discovery, there have been more than 20 other space-related findings that have come to light recently.

These discoveries include the identification of a distant galaxy, billions of light-years away, that spontaneously produced new stars at a surprising rate. Another significant finding includes the detection of water vapor in the atmosphere of an exoplanet that resides within a habitable zone, meaning it could potentially support life.

Furthermore, scientists have also made progress in understanding the origins of fast radio bursts (FRBs), which are mysterious cosmic signals that last only a few milliseconds.

They determined that magnetars, highly magnetized neutron stars, might be responsible for these bursts. Additionally, researchers have studied the phenomenon of stellar streams, which are remnants of smaller galaxies that were absorbed by the Milky Way. These streams are composed of stars and can help scientists reconstruct the evolution of galaxies.

In conclusion, ongoing advancements and discoveries in space exploration continue to captivate and astound scientists and enthusiasts alike. The potential existence of unknown planets within our Solar System, along with other recent revelations, highlight the vastness and complexity of our universe. These findings contribute to our understanding of celestial phenomena and uncover the mysteries that surround us, making it an exciting time in the field of space exploration.
