Astronomers have made significant discoveries, including the farthest galaxy GN Z11, which is 13.3 billion years old and 32 billion light years away due to the universe's expansion. They also found the faintest satellite galaxy, Virgo One, orbiting the Milky Way. Additionally, the youngest exoplanet, K-233-B, was discovered, providing insights into planetary life cycles. These findings were made using advanced telescopes like Hubble, Subaru, and Kepler, and published in leading scientific journals.
