Hubble: Ain't dead, won't quit

The image shows what NASA calls globular cluster Terzan 2, which exists in the constellation Scorpio.

“Globular clusters are stable, tightly gravitationally bound clusters of tens of thousands to millions of stars found in a wide variety of galaxies. The intense gravitational attraction between the closely packed stars gives globular clusters a regular, spherical shape. As this image of Terzan 2 illustrates, the hearts of globular clusters are crowded with a multitude of glittering stars,” NASA explains.

The Advanced Camera for Surveys (ACS) is Hubble’s most used camera, but it wasn’t part of the telescope when it was originally launched, but was added to the observatory in March of 2022. The ACS wavelength range extends from the ultraviolet, through the visible spectrum, and out to the near-infrared. Hubble recently celebrated the 20th year of the ACS which has captured 125,000 photos in that time and are the source of numerous discoveries.

March of 2022 was slightly less than 20 years ago so I'll assume a bit of a typo on petapixel's part. Unless George Jetson's dad did the servicing, always 20 years in the future.

March 2002. STS-109, Columbia (RIP) 36 EVA hours.

Fun Fact... .the Shuttle and Hubble were designed to be compatible. In orbit servicing was always part of the Hubble plan.

I wonder what it would be like to live in the middle of one of those clusters, specifically the visual aspects, particularily in the night time sky.

We live in a kind of boring area of the MW...

And most of us exacerbate that by living too close to city lights. :-(

If we were able to move our entire Solar System and put it straight in the middle of a globular star cluster, like 47 Tucanae, our night sky would be teeming with many stars.

In the case of 47 Tucanae, which has millions of members, stars would still appear as points of light since, due to their distance, they would not have diameters that are easily resolved by the human eye. They would also be more than a thousand times brighter than Earth’s nighttime star, Sirius.

To live on an Earth in a globular cluster would mean that the cluster’s stars (if they were like our Sun) would combine to create a night sky at around 20 times brighter than Earth’s night sky at full Moon.

As a (lapsed) amateur astronomer I couldn't think of a worse night sky. That would be awful. Very many of the best things to see in the night sky are very faint and that sky would destroy any chance of seeing any of them.

We're in a pretty damn good (read: boring) part of the galaxy, which is a gift in many ways. That quote about not living in interesting times springs to mind.

When you don't cut too many corners and follow sound engineering, things tend to last way longer than expected.
