The X-ray Imaging and Spectroscopy Mission (XRISM) spacecraft has delivered an "unprecedented tally of elemental sulfur spread between the stars," according to NASA.
00:00Sulfur. It's the fifth most common element on Earth.
00:05It also helped make our early world habitable and allows life to function now.
00:10But scientists have a lot of questions about where it hides in interstellar space.
00:17Using the CRISM satellite, astronomers have now x-rayed our galaxy's sulfur in unprecedented detail.
00:27Out in the vastness of space is the interstellar medium, the gas and dust between the stars.
00:36Scientists see lots of sulfur as gas in molecular clouds, cold, dense patches of the medium where stars and planets are born.
00:46But this type of sulfur tends to disappear quickly. Where does it go?
00:52To find out, scientists picked a region of gas and dust that wasn't too thin or too thick.
01:00Then they picked a bright x-ray source behind the patch so that the light would pass through it on its way to CRISM.
01:08This is like getting an x-ray here on Earth, but instead of the light being absorbed by tissue and bone, it's absorbed by different elements, like sulfur.
01:17CRISM showed scientists that sulfur in the interstellar medium can be found as both a gas and as a solid, and possibly mixed with iron.
01:26This aligns with studies of meteorites and may help explain how sulfur moves through the cosmos.
01:32It's also the first direct measurement of sulfur in both solid and gas phases.
01:38Thanks to CRISM, we're a step closer to understanding how life on our planet came to be.
01:47What is the arc �là?
01:48I'm looking for stains on arcs of precision.
01:52There isn't a gap between justiles and lemurя, but the factvir PHYF menos is the best is to to moral.
01:54I'm looking for muscle mass plus fancaries.
01:56Here is how if asthma looks for a few of course.
02:00Especially overnight and this isn't overwhelming or the obvious there can Kolleginnen אפsy.
02:02I'm looking for themes because you're looking for the smell of the temperature.
02:04It's probably a much bigger than the sun here that theenges are numbered the brushes.
02:07I'm looking for the Hay Auswira Center.
02:09I'm looking for� hundreds of巧 Illinois, I ain't paying attention.
02:11It's definitely a number of mining azt and this is showing that it's bulletiness.
