Intricacies of Helix Nebula Revealed with NASA’s Webb
Intricacies of Helix Nebula Revealed with NASA’s Webb - Lemmy.World
Webb captured a new close-up of an old favorite, the Helix Nebula. We’ve seen this region before with telescopes like Hubble and the retired Spitzer Space Telescope, but Webb zooms into this dying star with a deeper, more detailed view. https://science.nasa.gov/mission/webb/multimedia/images/#Engineering-And-Test-Images [https://science.nasa.gov/mission/webb/multimedia/images/#Engineering-And-Test-Images]

NASA’s James Webb Space Telescope has provided the first direct measurements of the chemical and physical properties of a potential moon-forming disk encircling a large exoplanet. The carbon-rich disk surrounding the world called CT Cha b, which is located 625 light-years away from Earth, is a possible construction yard for moons, although no moons are detected in the Webb data.

Expand your imagination 🍥 What appears to be a single galaxy is actually two that are very far apart! The closer galaxy lies in the center of the image, while the more distant galaxy appears to be wrapped around it in a phenomenon we call an “Einstein ring.” Einstein rings occur when light from a distant galaxy gets bent by the gravity of a massive closer-by object, in this case another galaxy. The light from the distant galaxy that would otherwise travel in a straight line follows the bend of gravitationally warped spacetime, brightening the light from behind the galaxy and acting as a sort of natural magnifying glass. Einstein predicted this effect in his theory of relativity. https://esawebb.org/images/potm2503a/ [https://esawebb.org/images/potm2503a/]
Arp 107 (MIRI Image)
Arp 107 (MIRI Image) - Lemmy.World
This image of Arp 107, shown by Webb’s MIRI (Mid-Infrared Instrument), reveals the supermassive black hole that lies in the center of the large spiral galaxy to the right. This black hole, which pulls much of the dust into lanes, also display’s Webb’s characteristic diffraction spikes, caused by the light that it emits interacting with the structure of the telescope itself. Perhaps the defining feature of the region, which MIRI reveals, are the millions of young stars that are forming, highlighted in blue. These stars are surrounded by dusty silicates and soot-like molecules known as polycyclic aromatic hydrocarbons. The small elliptical galaxy to the left, which has already gone through much of its star formation, is composed of many of these organic molecules. Credits Image NASA, ESA, CSA, STScI

One of the brightest nebulae in the night sky is Messier 42, the Orion Nebula, located south of Orion’s belt. At its core is the young Trapezium Cluster of stars, the most massive of which illuminate the surrounding gas and dust with their intense ultraviolet radiation fields, while protostars continue to form today in the OMC-1 molecular cloud behind. https://www.flickr.com/photos/nasawebbtelescope/53230009083/in/album-72177720305127361/ [https://www.flickr.com/photos/nasawebbtelescope/53230009083/in/album-72177720305127361/]
