What is galaxy decor?

Galaxy decor is any decorative item with swirling colorful lights inspired by the cosmos, outer space, and starry nights. This type of decor brings a calming presence to any room and will stimulate your senses. You may find purple, blue, pink, black, and white lights in galaxy decor.

Galaxy-themed decor can come in many different forms, including connect-and-go lights and DIY craft options such as a “galaxy in a jar” or putting together a “galaxy wall.” It’s a decor category so expansive that there's really no end to how creative you can get with galaxy designs – many of which are so simple you can do them yourself.
