This composite image is based on observations from the New Horizons Ralph/LEISA instrument made at 6:25 a.m. EDT on July 14, 2015, when New Horizons was 50,000 miles (81,000 kilometers) from Charon. The spatial resolution is 3 miles (5km) per pixel. The LEISA data were downlinked October 1 4, 2015, and processed into a map of Charon s 2.2 micron ammonia-ice absorption band. ... The ammonia absorption map from LEISA is shown in green on the LORRI image. ...

... Over the last decade the uninterrupted, high-resolution coverage of the Sun both from the excellent range of telescopes aboard many spacecraft and from ground-based instruments has led to a wealth of observations of small-scale dynamic events observed from the chromosphere to the transition region and corona. ... SoHO observations have further characterized many transient features, such as bi-directional jets, blinkers, coronal jets, and bright points. ...

... GSAOI Home . ... Science . ... Despite vast increase in our understanding of the evolutionary nature of planetary nebulae (PNe) during the last three decades, a central question remains: where is the missing mass? Theoretical evolutionary tracks predict that all stars with masses in the range 1.4-8 M Sun should become PNe. ... Clearly, much of the mass of the planetary nebula shell must remain un-ionized, and much of it may be in molecular form. ... The Magellanic Cloud PNe are ideal for this. ...
