Galactic Dust Clouds Are Shining in Scattered Hα Light
Bright emission nebulae, or HII regions, around hot stars are readily seen in Hα light. However, the all-pervasive faint Hα emission has only recently been detected and mapped over the whole sky. Mostly the Hα emission observed along a line of sight is produced by ionised gas in situ. There are, however, cases where all or most of the Hα radiation is due to scattering by electrons or dust parti...
متن کاملShining a Light on Fish at Night: An Overview of Fish and Fisheries in the Dark of Night, and in Deep and Polar Seas
—In aquatic environments, what one observes during the day can differ substantially by night.

Teleosts and elasmobranchs have evolved unique sensory and behavioral modalities for living in darkness. ...

متن کاملClouds in the Polar Night of Mars: Modeling and Observations with the Mars Climate Sounder
Introduction: Polar “cold spots” – regions of unusually low brightness temperature – affect the Martian climate by reducing the outgoing heat flux, which is balanced by the latent heat of CO2 sublimation. Since the Viking era, their cause has remained uncertain. Using radiometric observations from the Mars Climate Sounder (MCS) during southern winter, we previously reported that transient cold ...
