Planet Formation Survives Even in Extreme Ultraviolet Radiation, Webb Telescope Reveals
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: The James Webb Space Telescope has discovered that the essential building blocks for planet formation can survive in environments flooded with intense ultraviolet radiation, expanding our understanding of where planets can form in our galaxy.
📈 One key stat: The protoplanetary disk around star XUE 1 contains enough solid material to potentially form at least 10 Mercury-sized planets, showing planet formation can occur even in harsh radiation environments.
💬 One key quote: “These findings support the idea that planets form around stars even when the natal disk is exposed to strong external radiation,” said Eric Feigelson, distinguished senior scholar and professor of astronomy and astrophysics and of statistics at Penn State.
1️⃣ The big picture: Astronomers using the James Webb Space Telescope have discovered that planets can form even in cosmic environments bathed in extreme ultraviolet radiation. The research team examined a protoplanetary disk around the young star XUE 1 in the Lobster Nebula, located about 5,500 light-years away. This region contains more than 20 massive stars emitting intense radiation that previously was thought to potentially disrupt planet formation. Using advanced thermochemical models with Webb observations, researchers identified the composition of dust grains and various molecules crucial for planet formation despite these harsh conditions.
2️⃣ Why is this good news: This discovery significantly expands our understanding of where planetary systems can develop throughout our galaxy. Scientists can now look for planets in regions previously considered too hostile for their formation. The research reveals nature’s remarkable resilience, as these planet-forming disks adapt to survive even when bombarded with powerful radiation that erodes their outer regions. The compact disk structure detected around XUE 1 demonstrates an evolutionary strategy where planet formation continues in the protected inner regions. This breakthrough helps explain why astronomers are finding that planetary systems are very common around other stars throughout diverse cosmic environments.
3️⃣ What’s next: The study of XUE 1 serves as a foundation for future observational campaigns with both space and ground-based telescopes. Researchers plan to build a more comprehensive picture of planet formation across different cosmic environments. The James Webb Space Telescope will continue to probe the intricacies of planet formation in challenging environments throughout our galaxy.
