The world's first commercial satellite dedicated to monitoring carbon dioxide from orbit will launch later this year. It will be put up by the Canadian company GHGSat, which already flies six spacecraft tracking methane emissions. The new platform will use the same shortwave infrared sensor but be tuned to CO₂'s specific light signature in the atmosphere. The satellite will have a resolution at ground level of 25m, meaning it will be able to see major individual sources...

A newly discovered comet will make its closest approach to our planet on Wednesday. Astronomers say the object's journey toward us took around 50,000 years. Photographs captured by astronomers show a distinct green hue around the body of the comet. But those expecting a brilliant streak of emerald in the sky will be disappointed. Its brightness is right at the threshold of what is visible to the naked eye. "You might have seen these reports saying we're going to get this bright green object lighting up the sky,"...
