Now, astronomers studying the iron's decaying fingerprints in seafloor sediments have deduced that multiple supernovas probably exploded between 1.5 and 2.3 million years ago, and they think they know where in the sky the explosions could have occurred.
The distinctive shape of this background galaxy-- which is probably just forming-- has allowed astronomers to deduce that it has separate images at 4, 10, 11, and 12 o'clock, from the center of the cluster.
Coming back to the night sky, some astronomers originally thought that big clouds of dust, like the one shown in this new space photo, could hide enough light from some stars to keep the night sky dark.
Astronomers have tracked down the source of a gravitational wave and discovered the first observed kilonova: a nuclear furnace 100 million times brighter than the Sun producing thousands of times the entire mass of the Earth in heavy elements such as precious metals.
Prior to this result, there had been concerns among astronomers that such distant galaxies would not be detectable in this way, but A1689-zD1 was detected using only brief observations with ALMA.
