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

cyclopropenone – WIkipedia We report the first detection in space of propadienone, the linear isomer (l-H2C3O) of cyclopropenone (c-H2C3O). We also report the first detection of the isotopologue c-H213CCCO, and

Free organic volatiles and IOM thermal degradation products liberated by flash heating to ~610 °C of Bennu samples. Shown are total ion chromatograms obtained by pyrolysis analysis of Bennu (A–D)

Saturn’s moon Mimas, imaged by the Cassini spacecraft. A new study shows how such small ice moons could sustain a liquid ocean beneath an icy shell, and how that could

Close-up view of bacterial communities thriving at the vent site. The distance between the two green laser points is 9 cm, providing a scale for the dense microbial structures visible

Raman optical observations at 10× and 100× showing original halite hopper crystal and microbial movement within fluid inclusions entombed within the crystal structure. (A) Entire halite cubic crystal showing rectangular

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

ALMA Band 5 images of the HL Tau disk and the 321 GHz H2O line. The continuum (top left) and the JvM-corrected integrated intensity maps of the H2O line at

Schematic illustration of the favored Earth formation scenario implied by our results. Top: From left to right, we show the different formation stages of the Earth from a side-view of

(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
