Discovery of two new satellites of Pluto

Article Abstract:

The discovery of two additional moons around Pluto, named P1 and P2, makes Pluto the first Kuiper belt object known to have multiple satellites, the first satellite of Pluto being Charon. They are much smaller than Charon, with P1's diameter estimated to be ranging from 60 to 165 km, and P2 is 20% smaller than P1, and they appear to be moving in circular orbits in the same orbital plane as Charon.

A warm layer in Venus' cryosphere and high-altitude measurements of HF, HCl, [H.sub.2]O and HDO

Article Abstract:

The detection of an extensive layer of warm air on Venus at altitudes 90-120 km on the night side (cryosphere) that is attributed to adiabatic heating during air subsidence is reported.
