Planets
The chemical composition of the Earth's core is still poorly understood, despite more than 60 years of research
New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 & 2 observations made decades ago
The dust that coats much of the surface of Mars originates largely from a single thousand-kilometer-long geological formation
In 1996, shortly after arriving at Jupiter, Galileo made a surprising discovery: Ganymede had its own magnetic field
New mathematical calculations reveal that Mercury's crust is thinner than anyone thought
Researchers identified biosignatures about 1,300 feet below ground in the Frasassi Caves in central Italy
The simulations are necessary to establish models of the atmospheres of far-distant worlds, models that can be used to look for signs of life outside the solar system
Investigating exoplanet atmospheres can provide new insight into how and where planets form around a star
Researchers use multiple, miniature instruments to directly detect and analyze life in the Canadian high Arctic, one of the closest analogs to Mars on Earth
A recent NASA study suggests that there may be another explanation for patterns in disks of dust and gas around young stars
