Sphere of Colour


The most common
feature is the presence of spicules,
long thin fingers of luminous gas
which appear like the blades
of a huge field of fiery grass
growing upwards from the photosphere below.

Spicules
rise to the top of the chromosphere
and then sink back down again
over the course of about 10 minutes.

Similarly,
there are horizontal wisps of gas
called fibrils,
which last about twice as long as spicules.

Filaments
(and prominences,
which are filaments viewed from the side)
underlie many coronal mass ejections
and hence are important
to the prediction of space weather.

Solar prominences rise
up through the chromosphere
from the photosphere,
sometimes reaching
altitudes of 150,000 km.
These gigantic plumes
of gas
are the most spectacular
of solar phenomena,
aside from the less frequent
solar flares.
The chromosphere
(literally, "sphere of colour")
is the second of the three main layers
in the Sun's atmosphere
and is roughly 2,000 kilometres
deep.
It sits
just above
the photosphere
and just below
the solar transition region.
