New Space satellite pinpoints industrial emissions of methane emissions

Methane may not be as abundant in the atmosphere as carbon dioxide, but with a global warming potential many times greater than carbon dioxide, monitoring and controlling industrial emissions of this potent gas is imperative to helping combat climate change. GHGSat is a New Space initiative that draws on Copernicus Sentinel-5P data for mapping methane hotspots – and its Claire satellite has now collected more than 60 000 methane measurements of industrial facilities around the world.

Study: A plunge in incoming sunlight may have triggered “Snowball Earths”

Findings also suggest exoplanets lying within habitable zones may be susceptible to ice ages.

ExoMars finds new gas signatures in the martian atmosphere

ESA’s ExoMars Trace Gas Orbiter has spotted new gas signatures at Mars. These unlock new secrets about the martian atmosphere, and will enable a more accurate determination of whether there is methane, a gas associated with biological or geological activity, at the planet.

The ultimate RAVE: final data release published

How do the stars in our Milky Way move? For more than a decade RAVE, one of the first and largest systematic spectroscopic surveys, studied the motion of Milky Way stars. The RAVE collaboration now published the results for over half a million observations in its 6th and final data release. RAVE succeeded in measuring the velocities, temperatures, compositions and distances for different types of stars. The unique database enables scientists to systematically disentangle the structure and evolution history of our Galaxy.

RAVE observed nearly half a million stars of our Galaxy. The Sun is located at the centre of the coordinate system. The colours represent radial velocities: red are receding stars and stars depicted in blue are approaching.

Dead star emits never-before seen mix of radiation

ESA’s Integral helps unravel origin of Fast Radio Bursts A global collaboration of telescopes including ESA’s Integral high-energy space observatory has detected a unique mix of radiation bursting from a dead star in our galaxy — something that has never been seen before in this type of star, and may solve a long-standing cosmic mystery.
