What Is The Big “Cosmic Question Mark” In Space That JWST Found?
- JWST captured the first cosmic question mark in 2023, near the star-forming region Herbig-Haro 46/47.
- A second question mark appeared in 2024 due to gravitational lensing by the massive cluster MACS-J0417.5-1154.
- NASA explains the lensing pattern shows two distant galaxies forming a question-mark shape as part of an early interaction.
- The 2023 and 2024 findings help scientists understand how galaxies grow through mergers over cosmic time.
- NASA notes that the question-mark shapes arise from distant, not nearby, objects in infrared imaging.
- The article notes the initial focus was on star formation, not the question-mark shape.
- The 2023 image highlighted Herbig-Haro 46/47 as the main point of interest near the question mark.
- Astronomers describe the 2024 lensing case as beginning of an interaction between galaxies.
- The article emphasizes that gravitational lensing can produce multiple images of distant objects.
