Cyclopropenylidene Detected

Using high sensitivity spectroscopic observations from the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected a small cyclic molecule called cyclopropenylidene (C3H2) in the atmosphere of Titan, the largest moon of Saturn. This composite image shows an infrared view of Titan. In this image blue represents wavelengths centered at 1.3 …

Ancient Magnetosphere

Solar storms strip a planet’s atmosphere over time, and only a strong magnetosphere would be able to provide maximum protection. Lunar samples gathered by NASA’s Apollo missions recently revealed that the Moon had its own global magnetosphere, lasting from about 4.25 to 2.5 billion years ago. According to new research, …

MAVEN Detects Metal Ions in Martian Atmosphere

NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) mission has made the first detection of the continuous presence of iron, magnesium, and sodium ions in the electrically charged upper atmosphere (ionosphere) of the Red Planet. MAVEN is exploring Mars’ upper atmosphere in detail to understand how Mars changed from a wet …
