SUNSET:

The editors of Sky & Telescope make every effort to provide accurate information, but errors do sometimes slip through. We correct all mistakes online as well as printing corrections in the magazine. So if you see something questionable in the magazine, check below to see if it's a known problem.
This article lists all known errors in issues of Sky & Telescope for 2022. See also the errata listings for other years.
April 2022
Page 10: In “Nearest Supermassive Black Hole Pair Discovered,” François Schweizer and team identified the galaxy’s double nucleus, and showed that one of them hosts an active supermassive black hole, in 2018. Karina Voggel and colleagues significantly improved the mass measurements for both black holes in 2022.
Page 55: The nebula sharing the frame with the Horsehead Nebula in the photo is NGC 2023.
Page 56: An astrophotographer reduces the effective noise by half each time they multiply the number of images by four.
May 2022
Page 30: The image of NGC 4725 was taken with a 4-inch f/6.5 refractor.
June 2022
Page 59: In the “Select Targets for Beginning Sketchers” sidebar, the Owl Cluster is NGC 457.
July 2022
Page 25: The name Little Gem refers to the planetary nebula NGC 6818, not NGC 6445.
Page 52: The Hubble Space Telescope captured the top image of Saturn on July 4, 2020.
August 2022
Page 64: The image at the top right of is M8.
SEPTEMBER 2022
Page 11: The team that applied its own analysis techniques to the LIGO, VIRGO, and KAGRA collaboration data and found 10 new candidates is from the Institute for Advance Study.
Page 50: The predicted minima of Algol on August 31st was 20:39. And the published Algol predictions for September 2022 were actually those for September 2023. The correct predictions are listed below:
| Date in September | Universal Time |
| 3 | 17:28 |
| 6 | 14:16 |
| 9 | 11:05 |
| 12 | 7:53 |
| 15 | 4:42 |
| 18 | 1:31 |
| 20 | 22:19 |
| 23 | 19:08 |
| 26 | 15:57 |
| 29 | 12:45 |
Page 52: In “A Lingering Jovian Mystery,” the observations of Io’s flash in 1983 from Mauna Kea matched those from Palomar Mountain.
Page 52: The graph contains errors in the vertical scale. It should display increasing increments of 0.5. See the corrected graph below.

Page 74: In the illustration of Earth, the continents should have been rotated 23.4° clockwise, aligning Earth’s equator with the Celestial equator. A corrected illustration appears here.

The inaugural Sky & Telescope article of "Beginner's Space - What is the Ecliptic?" already has a serious error: the Earth is drawn incorrectly! Even in this artful depiction, it's clear that the orientation of the continents should be rotated clockwise by 23.4°.
In the equatorial-azimuthal projection used there, the Geographic North Pole of the Earth (which of course projects to the North celestial pole) should emanate from above central Canada, not from above eastern Canada, as drawn in the article. Similarly, the Celestial equator (not the Ecliptic) should be drawn as the projection of the Earth's equator (as correctly described in the article), which of course runs across the top of South America.
Let's hope not too many new readers are confused!
