Published in the Publications of the Astronomical
Society of Japan on June 27, 2025, this
international study marks the first direct
detection of both solid and gaseous sulfur in the
interstellar medium, using data from the Japan-led
XRISM (X-ray Imaging and Spectroscopy Mission)
satellite.

Why Sulfur Matters Beyond Earth

Sulfur plays a pivotal role not only in
astrophysics but also in planetary science and
biology. On Earth, sulfur is essential to
liferCoit is a component of amino acids, proteins,
and enzymes. In space, understanding where
sulfur resides helps scientists refine models
of planet formation, habitability, and
astrochemistry.

Tracking sulfur through its different cosmic
environments may also help explain the delivery
of volatile elements to young planets via
meteorites and comets. The fact that sulfur can
switch states so easilyrCofrom gas to solid and
back againrComakes it a highly dynamic tracer of
chemical processes across varying densities and
temperatures in the galaxy.

I've often wondered why the elements condense into nearly pure
agregates. Why do you get nearly pure sulfur precipitating around
volcanic vents when a lot of elements are are in the gas? Why do veins
of gold form in granite? Why can diamonds form in the crust of the
earth? When a star explodes you just get stellar dust clouds and the
elements start forming larger particles. You get molten conglomerates
like the early earth and the elements seem to find each other and you
get veins of gold and gold nuggets forming with the quartz crystals.
Why isn't everything just a big mess?
