Explanation:
What do the famous
Eagle Nebula star pillars look like in X-ray light?
To find out, NASA's orbiting
Chandra X-ray Observatory
peered in and through these interstellar mountains of star formation.
It was found that in
M16 the
dust pillars themselves do not emit many
X-rays,
but a lot of small-but-bright X-ray sources became evident.
These sources are shown as bright dots on the
featured image which is a composite of exposures from
Chandra
(X-rays),
XMM (X-rays),
JWST
(infrared),
Spitzer
(infrared),
Hubble
(visible), and the
VLT
(visible).
What stars produce these X-rays remains a
topic of research, but some are
hypothesized to be hot,
recently-formed, low-mass stars, while others are
thought to be hot, older, high-mass stars.
These X-ray hot stars
are scattered around the frame -- the
previously identified
Evaporating Gaseous Globules (EGGS) seen in
visible light
are not currently hot enough to emit X-rays.
