Eris and the Kuiper belt

A team of researchers used observations from the Webb Space Telescope (in white) to detect methane gas at Make-Make. Sharp emission peaks near 3.3 microns reveal methane in a gaseous state above the surface of Make-Make. A continuum model (in light blue) has been added for comparison. Gas emission peaks are identified where the observed spectrum rises above the continuum. An artist's impression of the surface of Make-Make is shown in the background. Credit: Courtesy of S.

Webb Telescope Discovers Gas for the First Time on Distant Dwarf Planet Makemake

The discovery makes Make-Make only the second trans-Neptunian body, after Pluto, to have gas detected. The researchers suggest that it may have a thin atmosphere or be geologically active.
The newly discovered trans-Neptunian object, 2017 OF201, hints at more hidden bodies beyond Neptune.

Astronomers have discovered a mysterious new world at the edge of the solar system.

Trans-Neptunian object 2017 OF201, with a diameter of about 700 km and an extreme orbit of about 25,000 years, may be considered a dwarf planet – and hints at the existence of dozens of other hidden bodies beyond Neptune
Many objects have been discovered at the edge of the solar system. Figure: Avi Blizovsky using FLEX-1

Astronomers discover mysterious new objects beyond the edge of the solar system

Observations made with the Subaru Telescope in Hawaii have revealed new objects in the outer region of the Solar System, pointing to a large, unknown population beyond the Kuiper Belt.

A dwarf planet has been discovered far beyond Pluto's orbit
