Science and sensation in microgravity
... flying laboratories in a state of microgravity, which gives freedom from, for example, hydrostatic pressure, convection, Archimedes’ principle, sedimentation and amplifying capillarity, wettability, and the effects of surface tension (purification...

How to grow plants in a spacecraft
...of the atmosphere, creating an unusual atmospheric composition and difficulty in watering (with or without support). There is no air convection in outer space, so if the growing station is not sufficiently ventilated any gas emitted by the plant will...

Was early Mars warmed by cirrus cloud cover?
... ground. For their models, the duo, Ramses M. Ramirez and James F. Kasting, construct a single-column radiative-convective climate model and test different (ice) crystal sizes, cloud thicknesses, and cloud fractions to simulate differing...

Earth's magnetic north pole is on the move and its going fast
... big giant magnet is the main reason humans populate the planet the way we do today. The swirling convective currents of molten iron in the Earth’s outer core throws out a protective shield, that protects life from...

Storm-plagued exoplanet revealed in detail with GRAVITY
... from the interior, with rays of warm light swirling through stormy patches of dark clouds,” says Lacour. “Convection moves around the clouds of silicate and iron particles, which disaggregate and rain down into the...

Energetic eruption helps astronomers peer deep within Jupiter's atmosphere
... the eruption in detail. This led us to confirm the current theory that energetic plumes are triggered by moist convection at the base of water clouds, which are located deep in the atmosphere. The plumes bring up ammonia gas...
