This source is hiding behind our Galaxy at a distance of ~18 Mpc, located at a galactic latitide of 0 degrees. ... As we look towards longer wavelengths, 60 micron, to try and penetrate the Galactic Plane, we still see confusion from galactic sources. ... If the image seems some what confusing that is because the MOST is a continuum radio telescope and when it looks in the direction of our Galaxy it detects radiation from sources within our Galaxy and from sources that may lie behind our Galaxy. ...

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. ...

NGC 5128 is the closest example of a giant early type (elliptical or S0) galaxy. Although often dubbed as a peculiar elliptical galaxy since it has a dust lane with recent star formation and an active galactic nucleus, the majority of early type galaxies have similar structures as revealed by recent surveys. ...

. Multi-epoch observations of the ЮВ Pictoris b exoplanet. The planet was imaged in 2003 (left image) in the L' band (3.8 ЮМm) in the plane of the circumstellar disk surrounding the star (not seen here). It was detected again October 2009 (middle) when it had moved to the other side of the star. The new observations made March 2010 at 2.18 ЮМm are shown in the right panel. The planet has moved yet again relative to its position measured in 2009. Astronomy Astrophysics
