用反透镜方法获得了z=0.4星系团0024+1654中多个长弧形的高红移源星系的独特图像。哈勃太空望远镜的深度B波段和I波段成像由于背景源的强烈引力透镜而能够实现高分辨率的弧线。因此，前景簇中的引力透镜被用来获得远处源的放大视图。震源的四个强烈透镜图像导致了独特的重建。每一个长弧形，当没有透镜时，导致相同的重建的源图像，显示出串珠的环状形态。光是光环的U光度就相当于一个正常星系的光度。这很可能是一个正在形成的星系。
A unique reconstruction of the image of a high-redshift source galaxy responsible for multiple long arcs in the z = 0.4 cluster 0024+1654 is obtained by inverse lensing. Deep B- and I-band imaging with the Hubble Space Telescope enables high resolution of the arcs due to strong gravitational lensing of the background source. The gravitational lens in the foreground cluster is thus used to obtain a magnified view of the distant source. Four strongly lensed images of the source lead to a unique reconstruction. Each of the long arcs, when unlensed, leads to the same reconstructed source image, exhibiting a beaded, ringlike morphology. The U luminosity of the ring alone is equivalent to that of a normal galaxy. This is likely a galaxy in formation.
