DEEP IN THE SOUTHERN SKY, close to the celestial pole,
we find the small and mostly overlooked constellation
Chamaeleon. Named after the family of lizards that,
famously, can vary their color to blend into the background,
this aptly named stellar grouping also hides in plain sight. Its
brightest stars are only of 4th magnitude, so perhaps that's

roundings and does little to call attention to itself. Look for
the little lizard due south of 1.7-magnitude Beta (β) Carinae.
A real chameleon has a long tongue (up to twice its body
length) that it flicks out at high speeds to capture its prey -
insects, such as flies. So, it's definitely no coincidence that
celestial cartographers made sure that Musca, the Fly, is one
of its neighboring constellations. ¢
