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.
