NASA scientists study Aerogel for building habitats on Mars
Raising crops on Mars is far easier in science fiction than it will be in real life: The Red Planet is an inhospitable world. Among other challenges, subzero temperatures mean water can persist on the surface only as ice, and the planet’s atmosphere offers little protection to plants (or people) from the Sun’s radiation. ![]() Scientists are exploring how aerogel, a translucent, Styrofoam-like material, could be used as a building material on Mars. Aerogel retains heat; structures built with it could raise temperatures enough to melt water ice on the Martian surface.

NASA’s Juno spacecraft discovers Changes in Magnetic Field of Jupiter
The discovery will help scientists further understand Jupiter’s interior structure – including atmospheric dynamics – as well as changes in Earth’s magnetic field. A paper on the discovery was published today in the journal Nature Astronomy. ![]() This still from an animation illustrates Jupiter’s magnetic field at a single moment in time. The Great Blue Spot, an-invisible-to-the-eye concentration of magnetic field near the equator, stands out as a particularly strong feature.

NASA’s Dawn mission study shows Dwarf Planet Ceres could have had an OceanWritten by Elyssia Widjaja
The Dawn team found that Ceres’ crust is a mixture of ice, salts and hydrated materials that were subjected to past and possibly recent geologic activity, and that this crust represents most of that ancient ocean. ![]() This photo shows dwarf planet Ceres as seen by NASA’s Dawn. The map overlaid at right gives scientists hints about Ceres’ internal structure from gravity measurements.

NASA and NOAA study shows warmer weather increasing Carbon Emissions from Alaska TundraWritten by Ellen Gray
More carbon dioxide released to the atmosphere will accelerate climate warming, which, in turn, could lead to the release of even more carbon dioxide from these soils. A new paper led by Roisin Commane, an atmospheric researcher at Harvard University in Cambridge, Massachusetts, finds the amount of carbon dioxide emitted from northern tundra areas between October and December each year has increased 70 percent since 1975. ![]() Winter sun setting over the tundra polygons in northern Alaska in November 2015. As winter sets in and snow settles, the soils take time to freeze completely and continue to emit carbon dioxide long into the new year.

NASA Study suggests decreased Hydroxyl levels maybe the cause of recent Methane increasesWritten by Alan Buis
The second most important human-produced greenhouse gas after carbon dioxide, methane is colorless, odorless and can be hard to track. The gas has a wide range of sources, from decomposing biological material to leaks in natural gas pipelines. ![]() Rice paddy fields in India. Agriculture is one source of global methane emissions.
