This NASA/ESA Hubble Space Telescope image of NGC 7722, a lenticular galaxy located about 187 million light-years away, features concentric rings of dust and gas that appear to swirl around its bright nucleus.

This new Hubble image, released on Jan. 30, 2026, is the sharpest taken of NGC 7722, a lenticular galaxy located about 187 million light-years away in the constellation Pegasus. A lenticular, meaning “lens-shaped,” galaxy is a type whose classification sits between more familiar spiral galaxies and elliptical galaxies. It is also less common than spirals and ellipticals — partly because these galaxies have a somewhat ambiguous appearance, making it hard to determine if it is a spiral, an elliptical, or something in between.

在这张由NASA/ESA哈勃太空望远镜拍摄的NGC 7722图像中，同心分布的尘埃与气体环似乎正围绕着明亮的核心旋转。NGC 7722是一个距离地球约1.87亿光年的透镜状星系。

这张发布于2026年1月30日的哈勃新图像，是迄今为止对NGC 7722拍摄得最清晰的画面。NGC 7722是一个位于飞马座、距离地球约1.87亿光年的透镜状星系。透镜状星系（意为“透镜形状”）的分类介于我们更为熟悉的螺旋星系与椭圆星系之间。与螺旋星系和椭圆星系相比，这类星系较为罕见——部分原因在于它们的外观有些模棱两可，让人难以断定它究竟是螺旋星系、椭圆星系，还是介于两者之间的天体。
