Buried deep inside the dark cloud of gas and dust that fills the picture, this star gradually brightened 40-fold over the course of 2 years and has remained bright since 2015. The cause of such events is not clearly understood. This infrared image shows what we would see if our eyes were sensitive to wavelengths 3 times longer than visible light.
