A new report by the United Nations Environment Programme states that even in the most optimistic scenario, warming will peak at around 1.8 degrees. Returning below the threshold set in the Paris Agreement is only possible through immediate cuts

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.

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.

Methane: The Hidden Problem of Natural Gas

SwRI is studying how Saturn's largest moon maintains its dense atmosphere. Scientists think Titan's core is covered in layers of ice and a subsurface liquid ocean. New experiments show that nitrogen and methane gases produced by organic matter in the core seep to the surface, regularly renewing the atmosphere. Credit: Southwest Research Institute

New research suggests that nitrogen and methane seep from Titan's rocky core to the surface, helping to maintain its dense atmosphere. The findings could shed light on the planet's internal chemistry.

In the study, the scientists examined collisions that occur between the molecules. Collisions of atoms have been studied in the past, but atoms - according to classical physics - are spherical, while molecules have an elongated structure. The structure of a colliding body affects the way it will move after the collision. Will elongated molecules behave differently from spherical atoms? And is knowing their shape enough to predict the outcome of the collision? Illustration: pixabay.com.
