NASA Maps 450 Million Galaxies in Full Color, Creating Cosmic Fossil Record
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: NASA’s SPHEREx telescope has successfully mapped 450 million galaxies in full color while collecting detailed spectral data, providing unprecedented insights into the origins of our universe.
📈 One key stat: The telescope detected over 450 million galaxies and 100 million stars in our Milky Way, creating an unprecedented cosmic database that will enable discoveries for decades.
💬 One key quote: The principal investigator, Jamie Bock, highlights the universality of these findings in light of the mission’s key questions on origins: “The mission coverage of 25 months would yield data sufficient to support decades of astronomical study and exploration.”
1️⃣ The big picture: NASA has achieved a remarkable milestone in space exploration with the SPHEREx mission, which has mapped 450 million galaxies in full color across the observable universe. This groundbreaking telescope uses advanced spectroscopy to separate infrared light into 102 distinct color bands, allowing for unprecedented detail in cosmic observations. The spacecraft operates at extremely low temperatures to detect distant celestial bodies with low infrared intensity. Scientists are particularly focused on studying galaxy distributions to better understand cosmic inflation and the earliest moments after the Big Bang.
2️⃣ Why is this good news: The comprehensive sky maps created by SPHEREx represent a treasure trove of astronomical data that will benefit scientists for generations to come. NASA has committed to providing free access to these star maps, democratizing this wealth of knowledge for researchers worldwide. The detailed spectral analysis of hundreds of millions of celestial bodies will help unlock mysteries about galaxy evolution, cosmic inflation, and even the chemistry that made life possible on Earth. This mission combines cutting-edge technology with humanity’s fundamental curiosity about our universe in ways that promise numerous scientific breakthroughs.
3️⃣ What’s next: The SPHEREx telescope will continue its full-sky survey, gathering more data on galaxy distribution patterns and variations in extragalactic background light. Scientists will use this information to explore inflation physics, galaxy evolution, and life-enabling processes. The collected data will form an astronomical treasury supporting decades of future research and discoveries.
