Star Classification
... Star Classification The first people to combine a camera with a spectroscope were the father and son team of John and Henry Draper in the 1870s. Their work was carried on by Edward C. Pickering who, by 1918, had listed the spectra of over 200000 stars. Using details about luminosity and composition, ...

... Niedzielski et al. (2007). Briefly, we observe with the HET in its queue-scheduling mode and use the HRS at the R=60,000 resolution with the gas cell (I2 ) inserted in the optical path. In our target selection, we avoid bright objects, which are accessible to smaller telescopes. Consequently, more t ...

Are We Alone in the Universe?
... ✤ Now we know of nearly 2,000! Some estimates put the number of Earth-like planets in habitable zones at 20% of all stars! ✤ 400 billion stars in the Milky Way x 20% = 80 billion potentially habitable planets! Statistically, the answer is: There have to be other life forms out there ...
