Enigmatic spiral galaxy NGC 1097 lies about45 million light-years away in the southern constellationFornax.The small companion galaxy, just below and left of center, that seemsto be wrapped in its spiral arms, is notNGC 1097′smost peculiar feature though.Instead, This very deep exposure shows hints of faint,mysteriousjets, most easily seen to extend well beyond the bright arms towardthe lower right.In fact, four faint jets are ultimatelyrecognizedin optical images of NGC 1097.The jetstrace an X centered on the galaxy’s nucleus, but could befossil trails left over from thecapture of a much smaller galaxy in the large spiral’s ancient past.A Seyfert galaxy,NGC 1097′s nucleus also harbors amassive blackhole

Is this a picture of Mars or Earth? Oddly enough, it is a picture ofMars.What may appear to some as aterrestrial coastlineis in fact a formation ofancient layered hills and wind-blown sand onMars. The above-pictured region spans about three kilometers inSchiaparelli Crater. What created the layers ofsedimentis still a topic of research. Viable hypotheses includeancient epochs ofdeposit either from running water or wind-blown sand. Winds andsandstorms have smoothed anderoded the structures more recently. The “water” that appears near the bottom isactually dark colored sand. The image was taken with theMars Global Surveyor spacecraft thatoperatedaround Mars from 1996-2006 and returned over 200,000 images

This was just one more breathtaking view from the International Space Station. The Sun, a crescent Earth, and the long arm of a solar panel wereall visible outside a window when theSpace ShuttleAtlantis visited the orbiting outpost last week.Reflections from the window andhexagonallens flaresfrom the camera are superposed.The spaceshuttle landed Friday after a successful 10 daymissionto expand and resupply theISS.NumberedSTS-129,the space shuttle mission returned astronautNicole Stottto Earth from her stay on the ISS as aFlight Engineer in theExpedition 2021 crews.
