Ice in Ceres' shadowed craters linked to tilt history



Pasadena CA (JPL) Mar 23, 2017
Dwarf planet Ceres may be hundreds of millions of miles from Jupiter, and even farther from Saturn, but the tremendous influence of gravity from these gas giants has an appreciable effect on Ceres' orientation. In a new study, researchers from NASA's Dawn mission calculate that the axial tilt of Ceres - the angle at which it spins as it journeys around the sun - varies widely over the course of about 24,500 years. Astronomers consider this to be a surprisingly short period of time for such dramatic devi ... read more

Mars Volcano, Earth's Dinosaurs Went Extinct About the Same Time
Pasadena CA (JPL) Mar 21, 2017
New NASA research reveals that the giant Martian volcano Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity. The last volcanic activity there ceased about 50 million years ago - around the time of Earth's Cretaceous-Paleogene extinction, when large numbers of our planet's plant and animal species (including dinosaurs) went extinct. ... more

Newly formed stars are surrounded by a disc of dense gas and dust. This is called the protoplanetary disc, as material sticks together within it to form planets. Stars of different shapes and sizes are all born in huge star-forming regions. Scientists know that when a protoplanetary disc around a relatively small star is very close to a massive star, the larger star can evaporate parts of the pr ... more
