NASA has released one of the most detailed maps of dark matter ever created, captured by the powerful James Webb Space Telescope. The new map suggests that dark matter acts as a hidden cosmic framework — an invisible structure upon which galaxies, stars, and even planets are built.

Researchers from Durham University say the discovery could help scientists better understand how the Milky Way formed, and ultimately how Earth and life itself became possible. Because dark matter cannot be seen directly, scientists detected it by observing how its gravity bends light from distant galaxies — a phenomenon known as gravitational lensing.

The map covers a region of sky 2.5 times larger than the full moon and includes nearly 800,000 galaxies — far more than previous observations. Scientists describe dark matter as the “true architect” of the universe, shaping visible matter over billions of years.

With future missions like ESA’s Euclid telescope and NASA’s upcoming Roman Space Telescope, researchers aim to map dark matter across the entire universe, bringing us closer to solving one of cosmology’s greatest mysteries.

00:00NASA has revealed one of the most detailed maps of dark matter yet.
00:06Taken by the James Webb Space Telescope,
00:09the map suggests the elusive substance acts as a hidden framework
00:14on which entire galaxies are built.
00:17According to researchers from Durham University,
00:20this could help to unravel the mystery of the formation of our Milky Way
00:25as well as planet Earth.
00:27Dark matter is described as the glue that holds the universe together.
00:33However, because it's invisible,
00:36understanding exactly what it is or what is, does, has proved difficult.
00:44Scientists have previously suggested that when the universe began,
00:49dark matter and normal matter were sparsely distributed.
00:53Dark matter clumped together first before pulling in normal matter,
00:59creating regions where stars and galaxies began to form.
01:04By prompting this formation,
01:07dark matter also played a role in creating the conditions for planets to form,
01:13eventually allowing life to appear.
01:17To prove this is the case,
01:19the research team turned to NASA's James Webb,
01:23the largest and most powerful telescope ever launched to space.
01:28This allowed them to map dark matter with unprecedented precision.
01:34Because dark matter is invisible,
01:37the team looked for it by observing how its mass curves space itself,
01:43which in turn bends the light traveling to Earth from distant galaxies.
01:48The map shows that dark matter interacts with the rest of the universe through gravity,
01:55seen by the degree of overlap between maps of dark and normal matter.
02:02By revealing dark matter with unprecedented precision,
02:06our map shows how an invisible component of the universe has structured visible matter
02:13to the point of enabling the emergence of galaxies, stars, and ultimately life itself,
02:21explained Dr. Gavin Leroy Kothor of the study.
02:25This map reveals the invisible but essential role of dark matter,
02:32the true architect of the universe,
02:35which gradually organizes the structures we observe through our telescopes.
02:40In total, the area covered by the map is a section of sky about 2.5 times larger than the
02:49full moon.
02:50In the constellation Sexton's,
02:54it includes nearly 800,000 galaxies,
02:58about 10 times more than Webb's predecessor, Hubble, was able to observe.
03:04Dr. Diana Scognomiglio,
03:07co-author of the study from NASA's Jet Propulsion Laboratory,
03:12said,
03:13This is the largest dark matter map we've made with Webb,
03:17and it's twice as sharp as any dark matter map made by other observatories.
03:24Previously, we were looking at a blurry picture of dark matter.
03:29Now we're seeing the invisible scaffolding of the universe in stunning detail,
03:34thanks to Webb's incredible resolution.
03:37The team now plans to map dark matter through the entire universe,
03:42using the European Space Agency's Euclid telescope,
03:47alongside NASA's upcoming Nancy Gray's Roman Space Telescope.
03:52The sky is to Being
03:52to be invisible.
