Mars Icebreaker Life Mission

The European Space Agency’s Mars Express orbiter captured this view of Mars’ south polar ice cap Feb. 25, 2015. Three years later, the spacecraft detected a signal from the area to the right of the ice cap that scientists interpreted as an underground lake. Credit: ESA/DLR/FU Berlin, CC BY-SA 3.0 IGO

Analytical predictions for the astrometric effect of a moon with varying mass and distance to HD 206893 B. GRAVITY could in principle detect moons lower than a Neptune mass at larger periods. The fit of the GRAVITY data is shown as a green point assuming the mass and period as upper limits in our tentative detection. The orange area shows the plausible parameter space where a moon could be located, and still be potentially detectable with GRAVITY assuming an astrometric accuracy of 10 µas (see section 3.3). -- astro-ph.EP

(a) TEM image (mass thickness contrast) of a FIB-prepared cross section showing a deposited porous magnesium silicate layer on a silicon wafer. The layer has a variable thickness and a very high porosity. The thickness of the prepared TEM sample in beam direction is about 100 nm. The metal coating is protecting the surface during the FIB sample preparation. (b) and (c) Magnified view of the porous and foam-like structure of the film. Brighter areas represent less solid material in the beam direction. Areas with pore diameters over 100 nm are scarce, and most pores measure less than 20 nm. -- Heriot-Watt University

Illustration of the behaviour of the CARMENES visible channel CRX for the mid-M dwarf EV Lac. Top Left: Variation of RV as a function of wavelength (spacing is logarithmic). The CRX-index is the slope of RV vs log(λ) for each spectrum. A total of 10 CARMENES spectra are shown covering approximately one stellar rotation. The upper and lower boundaries are the fits to the most positive and negative RV values. Top right: The CRX-gradient, illustrating the CRX-index as a function of mean RV. Bottom Left and Bottom Right: CRX vs rotation phase and RV vs rotation phase illustrating the anti-correlation of CRX-index (i.e. the negative CRX-gradient shown in the top right panel). The plotted points in each panel are colour coded according to stellar rotation phase. -- astro-ph.EP
