茶杯座所在的星系距离地球约11亿光年，2007年市民科学家利用斯隆数字天空调查(Sloan Digital Sky Survey)数据：在Galaxy Zoo项目的可见光图像中首次发现了茶杯座星系。
Fancy a cup of cosmic tea? This one isn’t as calming as the ones on Earth. In a galaxy hosting a structure nicknamed the “Teacup,” a galactic storm is raging.
The source of the cosmic squall is a supermassive black hole buried at the center of the galaxy, officially known as SDSS 1430+1339. As matter in the central regions of the galaxy is pulled toward the black hole, it is energized by the strong gravity and magnetic fields near the black hole. The infalling material produces more radiation than all the stars in the host galaxy. This kind of actively growing black hole is known as a quasar.
Located about 1.1 billion light years from Earth, the Teacup’s host galaxy was originally discovered in visible light images by citizen scientists in 2007 as part of the Galaxy Zoo project, using data from the Sloan Digital Sky Survey.
