A trio of researchers at the CICERO Center for International Climate Research in Oslo, Norway, has found evidence that it could take decades for the planet to start cooling after human greenhouse gas emissions are reduced. ...
Observations made with the European Southern Observatory's Very Large Telescope (ESO's VLT) have revealed the telltale signs of a star system being born. Around the young star AB Aurigae lies a dense disc of dust and gas ...
