his landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth. Called the Cosmic Cliffs, Webb’s seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest “peaks” in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image. The blistering, ultraviolet radiation from the young stars is sculpting the nebula’s wall by slowly eroding it away. Dramatic pillars tower above the glowing wall of gas, resisting this radiation. The “steam” that appears to rise from the celestial “mountains” is actually hot, ionized gas and hot dust streaming away from the nebula due to the relentless radiation. Webb reveals emerging stellar nurseries and individual stars that are completely hidden in visible-light pictures. Because of Webb’s sensitivity to infrared light, it can peer through cosmic dust to see these objects. Protostellar jets, which emerge clearly in this image, shoot out from some of these young stars. The youngest sources appear as red dots in the dark, dusty region of the cloud. Objects in the earliest, rapid phases of star formation are difficult to capture, but Webb’s extreme sensitivity, spatial resolution, and imaging capability can chronicle these elusive events. https://www.nasa.gov/image-feature/g...-of-star-birth Last edited by GasoLane; 14-07-2022 at 05:48 PM.

Be careful what you might find out there.
A few months ago didn't they put some radio signal out into deep space looking for signs of life. And they sent drawn images of humans or something. Hey America, did you ask the rest of the world what they thought about that? I don't want some alien finding that and thinking we're any easy target, puny humans and we end up with a War of the Worlds scenario.

Happened to catch a little bit of discussion about this mission on the ABC radio last night when I popped out to pick up the daughter (I normally listen to triple m but can't stand the AFL drivel so listen to the ABC when that happens). There was a lady astronomer on there talking about the photos that were captured and how the light captured was generated by those starts between 13 and 14 billion years ago....not that much longer after the 'big bang'.
Mind boggling to think about that. She also said there's a good chance that some of those very starts have already burnt themselves out and don't exist anymore. Jaydee, you'll be very concerned that, in her view, given the immense size of the universe, it's hard to believe that earth contains the only living organisms! Be careful they are out there!

No doubt FGX50, too hard to comprehend that we're the only ones in all those universes out there.

I thought that the earth was flat & all of these stars were inside the "dome".

To even fathom the size of the universe is impossible. The Milky Way is around 100,000 light years across (pretty sure we’re a smaller galaxy). Look at how many galaxies are in those photos, the distance that picture covers, I’m not sure there’s a number to cover it.
The universe is expanding faster than the speed of light, so right now there are new galaxies being born that we will never be able to see. And one day there will be a civilisation somewhere that won’t know of other stars and galaxies as the universe will be expanding so fast their light will never reach them. We’re definitely lucky to exist when we do. |

Then there’s the prospect of that life being so much more intelligent than us that we would be no more than poorly trained circus animals to them. For all we know we may already have been observed and ignored. |

Yep, 99% of scientists couldn’t give a stuff about politics. They just want to advance humanity. May that never change.

Hypothetically, which country would be ideally suited to make "first contact"? Assuming that it hasn't already happened.
