Abstract The total number of true, likely and possible planetary nebulae (PN) now known in the Milky Way is nearly 3000, double the number known a decade ago. The new discoveries are a legacy of the recent availability of wide field, narrowband imaging surveys, primarily in the light of H-alpha. In this paper, we summarise the various PN discovery techniques, and give an overview of the many types of objects which mimic PN and which appear as contaminants in both Galactic and extragalactic… 
Planetary nebulae and their mimics: The MASH-MEN Project
Abstract The total number of true, likely and possible planetary nebulae (PN) now known in the Milky Way is about 3000, approximately twice the number known a decade ago. The new discoveries are a
Planetary nebulae seen with TESS: Discovery of new binary central star candidates from Cycle 1
Context. It has become clear in recent years that binarity plays a crucial role in many aspects of planetary nebulae (PNe), particularly with regard to the striking morphologies they exhibit. To
New Galactic Planetary nebulae selected by radio and multiwavelength characteristics
We have used the Cornish radio catalogue combined with the use of multi-wavelength data to identify 62 new Planetary Nebula (PN) candidates close to the Galactic mid-plane. Of this sample 11 have
New planetary nebulae with ISM interaction discovered with IPHAS
Abstract The low surface brightness usually associated with nebulae mixing with the ISM has long been a substantial obstacle in the observation and statistical study of these interactions. Thanks to
Searching for Faint Planetary Nebulae Using the Digital Sky Survey
Abstract Recent Hα surveys such as SHS and IPHAS have improved the completeness of the Galactic planetary nebula (PN) census. We now know of ∼3000 PNe in the Galaxy, but this is far short of most
Planetary nebulae in the UWISH2 survey
Near-infrared imaging in the 1 ? 0 S(1) emission line of molecular hydrogen is able to detect planetary nebulae (PNe) that are hidden from optical emission line surveys. We present images of 307
Are planetary nebulae derived from multiple evolutionary scenarios?
Abstract Our understanding of planetary nebulae has been significantly enhanced as a result of several recent large surveys (Parker et al., these proceedings). These new discoveries suggest that the
Planetary nebula IC 5148 and its ionized halo
Context. Many round or roundish planetary nebulae (PNe) show multiple shells and halo structures during their evolutionary stage near the maximum temperature of their central star. Controversial
Multiwavelength diagnostic properties of Galactic planetary nebulae detected by the GLIMPSE-I
We uniformly analyse 136 optically detected planetary nebulae (PNe) and candidates from the GLIMPSE-I in order to develop robust, multiwavelength, classification criteria to augment existing
The binary fraction of planetary nebula central stars I. A high-precision, I-band excess search
We still do not know what causes aspherical planetary nebula (PN) morphologies. A plausible hypothesis is that they are due to the presence of a close stellar or substellar companion. So far, only

The local planetary nebula (PN) census is dominated by extremely evolved examples, and until recently, was incomplete. New discoveries from the AAO/UKST H$\alpha$ Survey and SHASSA, have partially
Ionized haloes in planetary nebulae: new discoveries, literature compilation and basic statistical properties
We present a comprehensive observational study of haloes around planetary nebulae (PNe). Deep Hα+[N ii] and/or [O iii] narrow-band images have been obtained for 35 PNe, and faint extended haloes have

Accurate emission line fluxes from planetary nebulae (PNe) provide important constraints on the nature of the final phases of stellar evolution. Large, evolved PNe may trace the latest stages of PN

Planetary nebulae (PNs) are circumstellar gas ejected during an intense mass-losing phase in the lives of asymptotic giant branch stars. PNs have a stunning variety of shapes, most of which are not
