Graphene

2023-05-25T20:14:08+00:00

Graphene Carbon foils are used in space plasma instruments to detect ions, neutral atoms, or electrons (Allegrini et al. 2016, Journal of Geophysical Research). They are extremely thin (of the order of a hundred atomic layers) and supported by fine grids over areas as large as tens of square centimeters. While they enable detection and characterization of the plasma particles, they also degrade measurements (e.g., time-of-flight to determine the speed of the particles) due to effects such as angular scattering and energy straggling. These unwanted effects usually scale with foil thickness and that is why we try to use the [...]

The Interior of Enceladus Looks Really Great for Supporting Life

2023-05-25T18:50:21+00:00

When NASA’s Voyager spacecraft visited Saturn’s moon Enceladus, they found a body with young, reflective, icy surface features. Some parts of the surface were older and marked with craters, but the rest had clearly been resurfaced. It was clear evidence that Enceladus was geologically active. The moon is also close to Saturn’s E-ring, and scientists think Enceladus might be the source of the material in that ring, further indicating geological activity. Read more at UNIVERSE TODAY
