Explanation:
Can dust be beautiful?
Yes, and it can also be useful.
The Taurus molecular cloud has several bright stars,
but it is the
dark dust that really
draws
attention.
The pervasive
dust
has waves and ripples and makes picturesque
dust
bunnies,
but perhaps more importantly, it marks regions where
interstellar gas is dense enough to
gravitationally contract to form stars.
In the image center is a light cloud lit by
neighboring stars that is home not only to a famous nebula,
but to a very young and massive famous star.
Both the star,
T Tauri, and the nebula,
Hind's Variable Nebula,
are seen to vary dramatically in brightness --
but not necessarily at the same time, adding to the mystery of this intriguing region.
T Tauri and
similar stars
are now generally recognized to be
Sun-like stars that are less than a few million years old
and so still in the early stages of
formation.
The featured image spans about four
degrees
not far from the
Pleiades star cluster,
while the featured dust field lies about 400
light-years away.
