Is the Hubble Telescope Outdated? His most recent and incredible image shocks everyone

The Hubble Space Telescope it is still in orbit to serve the scientific purposes of scholars around the world and, despite its venerable age, proves to be still a jewel of technology, capable of extensively competing with next-generation colleague James Webb Space Telescope.

The protagonist of the very recent Hubble shot that we propose today is the globular cluster NGC 6638, located in the constellation of Sagittarius. What immediately catches the eye, without too many words, is the surprising and vast amount of bright stars that cover the entire frame.

Even scientists have had a hard time counting the bright dots in the box, but as reported on the NASA website this is an image that encompasses tens of thousands of stars at the edges, and over a million stars in the central condensed area. The data was acquired by the inevitable Hubble astronomical instruments such as the Wide Field Camera 3 and the Advanced Camera for Surverys.

Globular clusters are found in almost all galaxies. They are the largest and most massive type of star clusters and tend to be very old and rather dense. We learned from the Hubble telescope that the typical distance between stars in a globular cluster is about one light year. But in the central core of a cluster, where the density is higher, much shorter distances can be reached, even at a third of a light year between one star and another. To give an example: Proxima Centauri (the closest star to the Sun) would be 13 times closer than it currently is!

It is thanks to Hubble’s decades-long observations that we are able to say more about the globular clusters, and about many other things concerning our universe. We can therefore say without a shadow of a doubt that the Hubble telescope is anything but obsolete and uselesseven if more and more often it begins to show severe ailments.
