NASA's James Webb Space Telescope has detected methane gas on the dwarf planet Makemake, suggesting the presence of a thin atmosphere or geological activity, making it only the second trans-Neptunian object after Pluto with confirmed gas. Future observations are needed to determine the exact mechanism behind this volatile activity.

Astronomers have discovered a new trans-Neptunian object, 2017 OF201, which has a vast orbit and potential dwarf planet size, suggesting more hidden bodies exist beyond Neptune in the Kuiper Belt. The discovery challenges previous assumptions about the emptiness of this region and highlights the power of open science in astronomical research.

Astronomers in Japan have discovered a distant object named Ammonite beyond Neptune, which is part of a group called Sednoids that have elongated orbits. This discovery challenges the hypothesis of a ninth planet influencing these objects, suggesting a more complex history of the solar system. Ammonite's orbit and characteristics provide insights into the early solar system and its evolution.

Scientists are racing to send a spacecraft to Sedna, a distant dwarf planet on an elongated orbit that will be closest to the Sun in 2076, to study its composition and origins before it moves away again. Due to the extreme distance, innovative propulsion methods like solar sails or fusion drives are being considered, but both face significant technical challenges. A successful mission could provide valuable insights into the early Solar System and potentially extraterrestrial material, but timing and technological development are critical.
