The Gemini Observatory is based in Hawaii and Chile, and divides its sites up into Gemini North and Gemini South. The latter recently received an upgrade called the Gemini Planet Imager (GPI), and it's used for finding planets. While there are many other tools out there used for similar purposes, the GPI is special given that its high-contrast output makes it good for finding young planets near bright stars, and 51 Eridani B (HD 29391) is the first one it's found.

According to Sci-News, the planet is "roughly twice the mass of Jupiter," and believe it or not, that's significant because of how small it is. They go on to note that most Super-Jupiters that have been discovered are in the range of five to thirteen times as massive as Jupiter.

James Graham is a professor at the University of California, Berkeley, and he's also a co-author of the Science Magazine published paper documenting the discovery. In a press release from the university, he's quoted as saying that “this is exactly the kind of planet we envisioned discovering when we designed GPI ... We wanted to find planets when they’re young so we can figure out the formation process.”

As he mentions, this planet is really young. It's only been around for twenty million years, and while that might sound like a long time, when taking into consideration that our own solar system is roughly 4.5 billion years old, it becomes even more obvious how wild this find really is. Just for some perspective, dinosaurs had gone extinct long before the 51 Eridani system had started forming.
