McGruff It
A veteran space telescope is still sending beautiful images near the end
McGruff's findings
Executive assessment
The image-viewing action is strong, but the article needs a dated update. Lead with NASA’s October 23 account of Swift’s completed mission (science.nasa.gov), then send readers to Chandra’s October 8 composite-image release (chandra.si.edu) and its wavelength-by-wavelength downloads (chandra.si.edu). The enduring story is both Swift’s scientific longevity and what its ultraviolet observations add to images made with other telescopes. ([science.nasa.gov](science.nasa.gov))
Key discoveries
- Swift entered safe mode after reaching roughly 171 miles (275 kilometers) on October 20; its operations team then commanded an end to operations in preparation for reentry. ([science.nasa.gov](https://science.nasa.gov/blogs/swift/2026/10/23/nasas-swift-mission-ends-ahead-of-re-entry/))
- Swift was designed for a two-year primary mission but remained scientifically productive for more than ten times that long. NASA credits it with observations of more than 2,000 gamma-ray bursts and data contributing to about 7,000 papers.
- The Small Magellanic Cloud composite includes Swift ultraviolet data alongside X-ray, infrared and optical observations from other facilities. Its pictured colors identify different data layers, not a single visible-light exposure. ([chandra.si.edu](https://chandra.si.edu/photo/2026/swift/more.html))
- For NGC 1097, Chandra supplies the X-ray layer associated with hot material near the central black hole; Swift supplies ultraviolet data, and optical observations show the galaxy’s visible structure. The release offers each layer separately.
Practical takeaways
- Update the article to say that Swift has stopped observing, not merely that reentry is approaching. Date the update explicitly: final observation October 20; NASA announcement October 23. ([science.nasa.gov](https://science.nasa.gov/missions/swift/nasas-swift-mission-ends/))
- Keep the image action, but call the October 8 release a collection of multi-observatory composites rather than photographs Swift alone recently sent back.
- For NGC 1097, invite readers to open the optical, ultraviolet and X-ray versions separately, then compare them with the composite.
- Explain that the image colors are assigned to different wavelengths; the X-ray and ultraviolet layers are not what a person would see with their eyes. ([chandra.si.edu](https://chandra.si.edu/photo/false_color.html?utm_source=openai))
Conflicting evidence
- The article’s present-tense claim that Swift continues to produce views is outdated as of October 26, 2026. NASA says Swift made its final observation on October 20 and that its operations have ended; reentry is expected in the next few weeks. ([science.nasa.gov](https://science.nasa.gov/missions/swift/nasas-swift-mission-ends/))
- The October 8 image release should not be described as four newly captured Swift photographs. These are composites assembled from multiple observatories’ data. Chandra lists observations for the Small Magellanic Cloud from 2012–2014 and for NGC 1097 from 2001–2025. ([chandra.si.edu](https://chandra.si.edu/photo/2026/swift/))
- Chandra’s release gives two approximate distances for NGC 1097: about 48 million light-years in its description and about 45 million in its fast facts. Avoid implying either figure is exact.
