Most previous observations suggested a flat spectrum from the near-IR to the optical, corresponding to a low-scale-height, high-molecular-weight atmosphere. My ob- servations are in general agreement with these findings, keeping the "door open" for a H2O-rich atmosphere for GJ 1214b, which ...
of infrared radiation with that of radiation at visual wavelengths, investigators are able to derive the diameter of the asteroid. Other remote-sensing techniques—for example, polarimetry, radar, and adaptive optics (techniques for minimizing the distorting effects of Earth’s atmosphere)—also are ...

This photo of Comet Hartley 2 from the November 2010 flyby performed by NASA's Deep Impact spacecraft shows jets containing water vapor ejecting from the core. From the European Space Agency:Did Earth’s oceans come from comets? This illustration shows the orbit of comet Hartley 2 ...
2018). The mission concept is to send an atmospheric probe that skims Venus atmosphere below the homopause to collect samples of Venus atmosphere, that are then analysed by a miniaturised quadrupole ion trap mass spectrometer (QITMS) once the probe is outside of Venus’ atmosphere. The goal ...
The GRS spectra are analyzed to determine the Venus elemental composition from the spectral signature of individual major, minor, and trace radioactive elements. As a test of such an instrument, a Schlumberger Litho Scanneroil well logging tool was used in a series of experiments at NASA's ...
