... G. Hill . ... In this paper I outline the FORTRAN programs available at the DAO to process and synthesize spectra, loosely described under the generic name REDUCE . ... The rationale behind the various reduction and analytic software is outlined, as well as the way the programs are controlled, e.g., menu, questions and answers, keywords and values, or the cursor. ...

Where On Earth Will The Sun Rise Earliest . ... This imaginary circle around the earth at 66є 33' north latitude where the Sun is split in half by the horizon at noon during the winter solstice is called the Arctic Circle . ... So we are looking for a point on earth that is on or just barely west of the International Date Line (it has to be Saturday, January 1—not Friday, December 31) and on or just barely north of the Antarctic Circle, where the Sun rises from its brief arc below the horizon. ...

One of the most important questions in astronomy today is the source of the ionising photons that caused a predominantly neutral Early Universe to evolve into the ionised one we see today. ... Although the global star formation history of the early universe is strongly constrained by current observations, we actually know little about the nature of star formation at this time (as given by the specific star formation rate). ...

... Using the DRAO Synthesis Telescope (Landecker et al. 2000), the Canadian Galactic Plane Survey ( CGPS ; Taylor et al. 2002) has captured a multitude of HISA features, the majority of which are invisible in prior surveys at lower resolution. ... Since the HISA gas temperature must be less than the background brightness temperature, all the H I shown in this poster has T ~ 100 K. Figure 1 provides panoramic views of the cold H I visible as HISA in the CGPS. ... GIFs: HISA + CO | HISA only | ...

NASA For 2015, International Year of Light, Chandra X-ray Observatory released new pics like this one of Whirlpool Galaxy M51. ... This feature makes the outer Solar System body a very special place, one of the very promising locaNASA tions where non-Earth life A liquid water ocean under the icy surface of Jupiter's moon Europa forms may actually exist. may be 60 miles deep. ... But, in order to determine if Earth's water came from a comet, we need to know if it has the same flavor. ...

... Radio-quiet, optically red ROSAT PSPC X-ray sources brighter than 1 ] 10~13 ergs cm~2 s~1 were searched for red (O[E [2.0, O № 20) counterparts in the Automated Plate-measuring Machine catalog of Palomar Sky Survey objects. ... The fraction of X-ray sources that may be red quasars, however, is much larger : D5% of the initial X-ray selected sample, D15% of the unidentiпed sources with APM colors, and D20% of X-ray bright objects with APM colors that will primarily be AGNs. ... 1998). ...
