Probably because the water in question is170 light years away around a white dwarf star, star GD61.
A new study published in Science magazine found that the debris left from the star’s collapse may have belonged to a small planet or asteroid that was made up of 26 precent water by volume.
This is important because it is the first time water has been found in a rocky, Earth-like planetary body in outside the Solar system. So it is a big discovery for xenobiologists searching for extra-terrestrial life. This assumes that life elsewhere requires water.
“The findings also may point to how water arrived on Earth. The scientist in the article said “[t]hese water-rich building blocks, and the terrestrial planets they build, may in fact be common.”
