但卻充斥在恆星和星系的背景上。共19年37,000張哈伯影像，透過公民科學志工和人工智慧演算法來完成，發現1,701條以前未被發現的小行星蹤跡。圖片來源：Pablo García Martín (UAM)、Elizabeth Wheatley (STScI)


研究人員表示看到如此多的候選小行星感到驚訝，而這些跡象表示這個族群存在，現在正透過使用哈伯檔案獲得的隨機小行星族群樣本來證實這一點，這對於深入了解太陽系的演化模型非常重要，並且為小行星帶的形成和演化提供了新的見解。這些較小的小行星可能是過去碰撞中大型小行星的碎片，或者當它們在數十億年前形成時，沒有任何機制使它們可以如同滾雪球般逐漸增大。

Asteroid Photobomb! Space Rocks Invade Hubble Galaxy View

"This parallax effect is somewhat similar to the effect you see from a moving car, in which trees by the side of the road appear to be passing by much more rapidly than background objects at much larger distances," STScI officials explained in the same statement. "The motion of Earth around the sun, and the motion of the asteroids along their orbits, are other contributing factors to the apparent skewing of asteroid paths."

Each asteroid was found manually by "blinking" images (quickly moving between different images of the same field of view) to look for asteroid motion. The arcs of the asteroid motions are distinct from separate arcs of blue light, which represent distorted images of galaxies that are behind the cluster. (The light from these galaxies is bent by dark matter, scientists said.)
