A pair of Sydney PhD students helped sharpen the view of humanity's most powerful space observatory – without leaving Earth.

A new paper published in Nature has revealed an international team has identified three ultra-massive galaxies – nearly as massive as the Milky Way – already in place within the first billion years after the Big Bang.

Detailed observations of a low-mass galaxy known as Firefly Sparkle that formed when the Universe was around 600 million years old provides insights into early galaxy formation, according to international researchers.

At least one in a dozen stars show evidence of planetary ingestion according to a paper published in Nature.
