New observations from 2019 (Prop 15953/Joel Kastner) reveal [Fe II] emission, shown here in pink, along the edges of the biopolar outflows of this young planetary nebula. I created this image specifically to clearly detail this discovery, deliberately arranging filters and assigning colors that would draw one's eyes to the new emission line data.

Hat tip to Bruce Balick for his original idea of removing the stars in the [Fe II] data. Through a strange series of emails I ended up "stealing" this idea, but he seemed happy about it when confession time came.

Data from the following proposals were used to create this image:
WFC3 ERO: Planetary Nebula
Young and Rapidly Evolving: a Panchromatic WFC3 Imaging Study of the Planetary Nebulae NGC 7027 and NGC 6302

Note that stars were manually removed from the F164N/[Fe II] data.

Red screen: F164N ([Fe II])
Red: F673N
Yellow-Green: F658N
Blue: F373N

North is 35.20° clockwise from up.

Gazing into deep this dusty maelstrom using near-infrared filters, Hubble reveals many stars and star-forming activities that might otherwise be obscured by dust. Strongly red spots indicate [Fe II] emission. There are only a few tiny splotches of those. Make of that what you will.

Another collisional mess from Julianne Dalcanton's voluminous interacting galaxies program. The weird galaxies to the right are supposed to look like a Star Trek ship, but I'm not sure I see it. Definitely one of those things that goes away after more than a glance. At this point I think it looks like someone tossing a pizza dough.

A close up view of a section of NGC 7023, also known as the Iris Nebula. Off the top frame, the star HD 200775 shines brightly, illuminating the nebula with blue light. This view includes near-infrared light, revealing the reddened light of stars attenuated by their dusty environment. Red and brown hues represent light shining through dust, while blue represents light reflecting from dust and gas.

Data from the following proposal were used to create this image:
The Exciting Wavelength of Extended Red Emission

Red: ACS/WFC F850LP
Green: ACS/WFC F625W
Blue: ACS/WFC F475W

North is 169.96° clockwise from up.

Mindlessly trying to waste some time lately by browsing for anything classified as a reflection nebula in the archive lately. This one is apparently a preplanetary nebula with the typical bipolar structure. Interestingly, the knots and linear formations seem fuzzier than other preplanetary nebulas I've processed. Not sure what that means if anything.

Data from the following proposal were used to create this image:
When does Bipolarity Impose itself on the Extreme Mass Outflows from AGB Stars? An ACS SNAPshot Survey

I removed the occulting finger by using the content-aware fill tool (smart data cloning).

Red: ACS/HRC F814W
Green: Pseudo
Blue: ACS/HRC F606W

North is up.
