Odd radio circles in space may come from black holes at their centres

While the purpose of this image was to focus on the bright star at the center for alignment evaluation, Webb's optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up. At this stage of Webb?s mirror alignment, known as ?fine phasing,? each of the primary mirror segments have been adjusted to produce one unified image of the same star using only the NIRCam instrument. This image of the star, which is called 2MASS J17554042+6551277, uses a red filter to optimize visual contrast.

Artist Jorge Ma?es Rubio, part of ESA?s future-oriented Advanced Concepts Team (ACT), has designed a place of contemplation to serve a future lunar settlement. It would be built on the sunlit rim of 21-km diameter Shackleton Crater, which is bathed much of the time in sunlight while overlooking a 4.2 km-deep interior mired in perpetual shadow.

This illustration shows the distant Comet Bernardinelli-Bernstein as it might look in the outer Solar System. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It is the most distant comet to be discovered on its incoming path.

First truly isolated black hole detected in interstellar space
