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). ...

... I will touch upon the following points: ґ fast evolution of the sizes of quiescent (elliptical) galaxies between z = 2 and z = 1; ґ prolonged star formation histories of dwarf spheroidal galaxies in the Local Group; ґ apparent lack of external sources of cold gas accretion for the nearby spiral galaxies; ґ old stellar ages and magnesium overabundance of the large-scale disks of nearby lenticular galaxies. ... This discovery has challenged the recognized scenarios of elliptical galaxy evolution. ...
