Hubble images shed new light on planetary nebulae

Researchers from Green Bank Observatory and the Rochester Institute of Technology shed new light on nebula formation process

On top is an image of the Butterfly Nebula (NGC 6302) captured by the Hubble Space Telescope in 2019 and released in 2020. Further analysis by researchers produced the RGB image on the bottom, which shows extinction due to dust, as inferred from the relative strength of two hydrogen emission lines, as red; emission from nitrogen, relative to hydrogen, as green; and emission from iron as blue.

Images of two iconic planetary nebulae taken by the Hubble Space Telescope are revealing new information about how they develop their dramatic features. Researchers from Rochester Institute of Technology and Green Bank Observatory presented new findings about the Butterfly Nebula (NGC 6302) and the Jewel Bug Nebula (NGC 7027) at the 237th meeting of the American Astronomical Society on Friday, January 15th.

GBT Image Contest Rules

Purpose 

This contest is designed to increase the number of compelling, high-quality radio astronomy visuals available for a wide range of education and public outreach programs. Any type of data-based visuals can be submitted including but not limited to; radio/composite emission images, animations, data visualizations, 3D models. All visuals submitted should contain and showcase radio data obtained with the Green Bank Telescope but they can display other multi-wavelength data as well. Entries submitted to this contest will be used by the Green Bank Observatory (GBO) Education and Public Outreach department in social media posts, the GBO Image Gallery, and made available for use by scientists, students, teachers, the general public, the media, and EPO professionals. 

Green Bank Observatory will award monetary prizes for First Place, Second Place, Third Place, and Honorable Mention:

  • First Prize – $1,000
  • Second Prize – $500
  • Third Prize – $250
  • Honorable Mention – $100 each

Entry Rules  

  • Any type of data based visuals can be submitted, including but not limited to: radio/composite emission images, animations, data visualizations, 3D models.
  • All visuals submitted should contain and showcase radio data obtained with the Green Bank Telescope  but they can display other multi-wavelength data as well.
  • Participants are allowed to submit more than one visual, but need to use a new form for each submission. Participants cannot win more than one prize.
  • Employees of AUI/NRAO/GBO and family members of employees are not eligible to receive prize money.
  • Deadline for submission: March 15, 2021

For still image files, include:

  1. JPEG, PNG, or TIFF file
  2. Minimum of 18in x 24in (46cm x 61cm) @ 300dpi
  3. GBT data file used to create image
  4. Detailed description of the image (e.g. spectral bands, spectral color assignments, instruments, facility, subject name, date, distance, spatial coordinate frame, spatial reference dimension, spatial scale)
  5. Public-friendly description of the image that relays the importance of the radio data shown as well as any other contextual information. 

For Animation/Video files, include:

  1. MP4, GIF, AVI, or MOV file
  2. Minimum of 1920x1080px resolution
  3. Detailed description of the science being shown (e.g. spectral bands, instruments, facility, subject name, date)
  4. Detailed description of how the animation/video was created and any associated FITS files.
  5. Public-friendly description of the animation or video that relays the importance of the radio data shown as well as any other contextual information. 

Judging 

  1. Green Bank Observatory will appoint a panel of judges to select the winning visuals.
  2. The judges come from a range of disciplines; they will be considering images according to the following criteria: aesthetics, artistic merit, originality, and scientific accuracy. See Judging Criteria for more details.
  3. Where there is reasonable doubt about whether a visual meets the entry criteria of the competition, the organizers reserve the right to disqualify the visual.  Wherever possible, the entrant(s) will be given the opportunity to answer queries from the judges before a final decision on disqualification is made.

Copyright and use of images 

In consideration of your entry to this context being accepted, you grant to Green Bank Observatory and AUI the unconditional right to let us distribute, remix, adapt, and build upon your work, even commercially, as long as they credit you for the original creation (CC BY Creative Commons License). You represent and warrant that you are the exclusive holder of any and all rights to the work and that no other individual or entity may claim any rights, title, and/or interest in the work. You additionally warrant that you have all necessary rights required to grant GBO/AUI the unconditional and unlimited use and exploitation of the work. You also warrant that you have sufficient permission of any recognizable persons appearing in the image to be able to grant rights to GBO/AUI.

Release

By participating, you release GBO, AUI, contest judges and staff members, their parent companies, affiliates, subsidiaries and their agents, respective officers, directors, employees, volunteers, and agents from any and all liability or responsibility for any claim arising in connection with participation in the Contest or any prize awarded.

Acceptance

By submission of the work to the Contest, you agree and accept all Contest terms and conditions, and the Release. By entering, you agree to be bound by these Contest rules and procedures, the terms and conditions on use of images, and the decisions of the sponsors and judges, which are final and binding on all matters. This Contest is void where prohibited and is subject to all applicable federal, state and local laws.

Judging Criteria   

Aesthetics and Originality: Does the visual show a unique way of presenting the radio data to the public? Is the visual appealing to look at, impactful, and does it draw in the viewer to learn more about the data being visualized? 

Artistic Merit: Does the visual show effective use of design elements to focus attention via placement and use of color, tone, or line; contrast; dynamics of form and shape; balance; unity of elements; and use of space? Is an overall level of skill demonstrated in the application and handling of the visualization technique and media?

Scientific accuracy: The visual is produced to convey a specific message or idea from the data. How well does the visual tell the story identified in the scientific and public statements? Is the data represented accurately. Pictorial manipulation or distortion of scientific data is sometimes necessary or even preferred, but it should be done clearly, with purpose and knowledge (described in the scientific statement). It should not be misleading or cause confusion. Does the visual do an effective job at representing and highlighting the radio data?

How are galaxies able to keep forming stars and planets? Astronomers from Texas Christian University are using the Green Bank Telescope to reveal more about this process, studying high-velocity clouds that are being pulled into our Milky Way galaxy by its gravitational pull.
