“Breathtaking” images of a stellar nursery in the Orion Nebula taken by the James Webb Space Telescope are revealing intricate details about how stars and planetary systems form.

The images, released Monday, shed light on an environment similar to our own solar system when it formed more than 4.5 billion years ago. Observing the Orion Nebula will help space scientists better understand what happened during the first million years of the Milky Way’s planetary evolution, said Western University astrophysicist Els Peeters in a news release.

“We are blown away by the breathtaking images of the Orion Nebula. We started this project in 2017, so we have been waiting more than five years to get these data,” Peeters said.

Is there a thread about the Perseverance Rover?? I looks for one but could not locate any. Here is news about the sedimentary rock they drilled out and seen potential organic signs in it.

Hubble Captures a Starry Scene​

A glittering multitude of stars in the globular cluster Terzan 4 fills this image from the NASA/ESA Hubble Space Telescope. Globular clusters are collections of stars bound together by their mutual gravitational attraction and can contain millions of individual stars. As this image shows, the heart of a globular cluster such as Terzan 4 is a densely packed, crowded field of stars – which makes for spectacular images!
The launch of Hubble in 1990 revolutionized the study of globular clusters. The individual stars in these dense crowds are almost impossible to distinguish from one another with ground-based telescopes. However, space telescopes can pick them apart. Astronomers took advantage of Hubble’s crystal-clear vision to study the stars that comprise globular clusters, discovering how these systems change over time.
This particular image came from Hubble observations designed to better understand the shape, density, age, and structure of globular clusters close to the center of the Milky Way. Unlike globular clusters elsewhere in the sky, those near the galaxy’s center have evaded detailed observation because of the clouds of gas and dust swirling around our galactic core. These clouds blot out starlight and complicate astronomical observations in a process astronomers refer to as ‘extinction.’
Astronomers took advantage of the sensitivity of two of Hubble’s instruments – the Advanced Camera for Surveys and Wide Field Camera 3 – to overcome the impact of extinction on Terzan 4. By combining Hubble imagery with sophisticated data processing, astronomers were able to determine the ages of galactic globular clusters to within a billion years – a relatively accurate measurement in astronomical terms!

Pretty cool.
