... nitriles as the main compound in photochemical hazes, especially on warm sub-Neptune type worlds, but a lack of observed methane (CH4) on such planets has hindered this line of investigation. Not only that, but the first exoplanet...
... small bodies made largely of ice. Indeed both Pluto and MakeMake are already known to be covered in frozen methane. Preliminary estimates of the moon indicate that it is in a circular orbit around MakeMake and thus completes a circuit around...
... are expected to arrive on the Red Planet on October 19, 2016.The TGO will then map the sources of methane and other gases on Mars, while also acting as a communications relay satellite. The lander will test landing...
... theory. Not only that, but the multi-hued appearance of Pluto’s surface is indicative of water, nitrogen and methane ices littering the planet and their discovery bolster the case for a thick ice shell. "Those...
... rates required to produce the ancient valleys. Other combinations of gases such SO2 (sulphur dioxide) and CH4 (methane) are also theorised, but although they might ‘fix’ one problem, disadvantages also creep in. SO2 for...
... and 80 days to get to Mars and eventually in as little as 30 days. The system consists of a spaceship that is refuelled with methane and oxygen in Earth orbit and also on Mars after landing there. He explained that to achieve the target...
