 Exploring life on Mars in the Gobi desert
Lanzhou (XNA) May 21, 2019
"Mars ain't the kind of place to raise your kids," as an Elton John hit goes.
However, a Mars simulation base in the middle of China's Gobi desert might be the perfect place to introduce young, budding astronauts to what life would be like on the red planet.
Surrounded by barren hills and red soil in northwest China's Gansu Province, "Mars Base One" allows visitors to explore a varie

Gas insulation could be protecting an ocean inside Pluto
Sapporo, Japan (SPX) May 21, 2019
A gassy insulating layer beneath the icy surfaces of distant celestial objects could mean there are more oceans in the universe than previously thought.
Computer simulations provide compelling evidence that an insulating layer of gas hydrates could keep a subsurface ocean from freezing beneath Pluto's icy exterior, according to a study published in the journal Nature Geoscience.

Juno Finds Changes in Jupiter's Magnetic Field
Pasadena CA (JPL) May 21, 2019
NASA's Juno mission to Jupiter made the first definitive detection beyond our world of an internal magnetic field that changes over time, a phenomenon called secular variation. Juno determined the gas giant's secular variation is most likely driven by the planet's deep atmospheric winds.
The discovery will help scientists further understand Jupiter's interior structure - including atmosphe

Giant impact caused difference between moon's hemispheres
Washington DC (SPX) May 21, 2019
The stark difference between the Moon's heavily-cratered farside and the lower-lying open basins of the Earth-facing nearside has puzzled scientists for decades. Now, new evidence about the Moon's crust suggests the differences were caused by a wayward dwarf planet colliding with the Moon in the early history of the solar system.
