Compass and Scale Image of Merging Star Clusters in 30 Doradus
30 Doradus, 30 Dor, Tarantula Nebula
170,000 light-years (52,000 parsecs)
The image was created from Hubble data from proposal 11360: R. O'Connell (University of Virginia), B. Balick (University of Washington), H. Bond (STScI), D. Calzetti (University of Massachusetts), M. Carollo (Swiss Federal Institute of Technology, Zurich), M. Disney (University of Wales, College of Cardiff), M. Dopita (Australian National University), J. Frogel (Ohio State University Research Foundation), D. Hall (University of Hawaii), J. Holtzman (New Mexico State University), P. McCarthy (Carnegie Institution of Washington), F. Paresce (European Southern Observatory, Germany), A. Saha (NOAO/AURA), J. Silk (University of Oxford), A. Walker (NOAO/CTIO), B. Whitmore (STScI), R. Windhorst (Arizona State University), and E.

The members of the science team are: E. Sabbi and D.J. Lennon (ESA/STScI), M. Gieles (University of Cambridge, UK), S.E. de Mink (STScI/JHU), N.R. Walborn, J. Anderson, A. Bellini, N. Panagia, and R. van der Marel (STScI), and J. Maíz Apellániz (Instituto de Astrofísica de Andalucía, CISC, Spain).
F336W (U), F438W (B), F555W (V), F656N (H-alpha), and F814W (I)
The images are composites of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Five filters were used to sample broad and narrow wavelength ranges for the UVIS image. The colors result from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
WFC3/UVIS image of 30 Dor
Blue: F336W (U) + F438W (B)
Green: F555W (V)
Red: F814W (I)
Orange/red: F656N (H-alpha)
