Scientists get best measure of star-forming material in early galaxy clusters
Astronomers have combined observations from several of the world’s most powerful telescopes to carry out one of the largest studies yet of molecular gas — the raw material which fuels star formation throughout the universe — in three of the most distant clusters of galaxies ever found, detected as they appeared when the Universe was only four billion years old.
Large number of dwarf galaxies discovered in the early universe
Researchers have found a large population of distant dwarf galaxies that could reveal important details about a productive period of star formation in the universe billions of years ago. It is believed that dwarf galaxies played a significant role during the so-called reionisation era in transforming the dark early universe into one that is bright, ionised and transparent.
Relationship revealed between chemicals found on comets
A new study reveals similarities and relationships between certain types of chemicals found on 30 different comets, which vary widely in their overall composition compared to one another. The research is part of ongoing investigations into these primordial bodies, which contain material largely unchanged from the solar system’s birth some 4.6 billion years ago.
