Star formation is often best manifested by bright H II regions.These are regions of hydrogen which have been ionized by ultraviolet photons which are emitted from massive stars (typically stars more than 20 times the mass of the Sun). ... A narrowband filter image centered on this wavelength will then readily reveal these H II regions and hence the current sites of star formation in a galaxy, The luminous blobs that can be seen here are all H II regions . ...

The night after the John Glenn program, I pitched the terraforming idea to my students. I asked them if they'd like to terraform Mars as a big class project; I wanted to throw the idea to them and see how they would react. Already I had a vision of splitting the class into several groups and having each group take charge of a portion of the project. ... Following my initial idea on how to conduct the project, I split the class into six groups, each student choosing his or her group. ...

... One of the strangest new findings in Earth 's atmosphere are the flashes found high above the thunderstorm clouds. Although the clouds themselves are at low altitudes to be important for ionospheric physics, the flashes can reach altitudes of about 90 km, i.e., the ionospheric E-region, and can thus be relevant also for space physics. The flashes seem to occur all around the world at a rate of at least one flash per minute. ... air glow flash . ... Space Physics Text Book ...
