 Context examples 

This image from NASA's Spitzer Space Telescope shows the Perseus Molecular Cloud, a massive collection of gas and dust that stretches over 500 light-years across.

(Spitzer Studies a Stellar Playground With a Long History, NASA)

The giant galaxy is located in the northern constellation Perseus.

(Hubble Surveys Gigantic Galaxy, NASA)

The Perseids are named after the Perseus constellation, as that is where they appear to originate from in the northeastern night sky.

(Perseid Meteor Shower Provides Opening Act for Solar Eclipse, VOA News)

The researchers used NASA’s Chandra X-ray Observatory to study a cold front located in the Perseus galaxy cluster that extends for about two million light-years, or about 10 billion billion miles.

(Scientists Surprised by Relentless Cosmic Cold Front, NASA)

After analyzing data from a radio survey conducted on a dust cloud in the Perseus constellation, two researchers from UC Berkeley and the Harvard-Smithsonian Astrophysical Observatory have concluded all sun-like stars are probably born with a companion.

(Our Sun Could Have Been Born With an Evil Twin Called "Nemesis", The Titi Tudorancea Bulletin)

As the cold front travels through the galaxy cluster, it passes through a harsh environment of sound waves and turbulence caused by outbursts from the supermassive black hole at the center of Perseus.

(Scientists Surprised by Relentless Cosmic Cold Front, NASA)

Infrared radiation from warm dust generates much of the glow seen here from the Perseus Molecular Cloud.

(Spitzer Studies a Stellar Playground With a Long History, NASA)

Perseus is the same cluster where astronomers discovered sound waves with a note of B-flat 57 octaves below middle-C plus a giant wave about twice the width of the Milky Way galaxy.

(Scientists Surprised by Relentless Cosmic Cold Front, NASA)

One of the most surprising aspects of this new research is that the cold front in Perseus remains sharp, even after billions of years.

(Scientists Surprised by Relentless Cosmic Cold Front, NASA)

While cold fronts in the Earth's atmosphere are driven by rotation of the planet, those in the atmospheres of galaxy clusters like Perseus are caused by collisions between the cluster and other clusters of galaxies.
