Astronomers hope that studying the aftermath of a deep space collision can help use better understand how our galaxy formed.
Astronomers aren’t sure what caused this massive space collision
This dust has clumped together to create multiple rocky pieces which astronomers call planetesimals. Think of planetesimals as rocky celestial objects that help form new planets. These objects crash into each other, exchanging materials, and sometimes grow larger than before, forming new planets entirely.NASA’s Spitzer Space Telescope
Using the data from the telescope, as well as data from other telescopes on the ground, Su and her team were able to estimate the size and shape of the collision’s aftermath.The star cluster NGC 1805 as imaged by the Hubble Space Telescope. Image source: ESA/Hubble & NASA, J. Kalirai
