Camelopardalis Constellation: A Cascade of Stars

The Giraffe has few bright naked-eye landmarks, but binoculars uncover a striking chain of stars. A compact cluster, a spiral galaxy and the remnants of a stellar eruption add different physical stories behind the apparent pattern.

Cetus Constellation: A Changing Star With a Long Tail

Cetus contains Mira, a star whose brightness changes over months, and the active spiral galaxy M77. Ultraviolet observations revealed a long trail of material behind Mira, showing how a familiar stellar point can hold a much larger story.

Aries Constellation: A Giant Star and a Distorted Spiral

Aries holds a bright stellar landmark and a distant spiral with an uneven shape. Hamal reveals an orbiting planet through small changes in its light; NGC 772 shows how a neighbouring galaxy can alter an entire spiral arm.

Pegasus Constellation: An Autumn Square, a Surprise Planet

Pegasus is easy to approach through four stars forming a large square. The same sky region leads toward a dense star cluster, a distant galaxy and the Sun-like star whose unexpected planet helped transform astronomy.
