We present IRAC and MIPS images and photometry of a sample of previously known planetary nebulae (PNe) from the Surveying the Agents of a Galaxy's Evolution (SAGE) survey of the Large Magellanic Cloud (LMC) performed with the Spitzer Space Telescope. Of the 233 known PNe in the survey field, 185 objects were detected in at least two of the IRAC bands, and 161 detected in the MIPS 24 ЮМm images. ... We also explore the potential value of IR PNe luminosity functions (LFs) in the LMC. ...

... Time-series of high resolution spectra have been obtained during three nights and several important events were detected. Observations contained several chromospheric lines, allowing to investigate simultaneously the response of the chromosphere at different heights. A detailed analysis of the H alpha line behaviour, in particular, has revealed prominece clouds and plage-like regions in this star. ... Promience clouds are seen to lie below the co-rotation radius. ...

A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ...
