Los Angeles Times : Gravitational lensing has revealed a galaxy that, despite being just 700 million years old, has a dust-to-gas ratio similar to that of the Milky Way, which is 13 billion years old. Darach Watson of the University of Copenhagen and his colleagues were able to examine the distant galaxy because its light gets amplified by passing through a massive galaxy cluster called Abell 1689 . Galaxies that formed early in the universe’s history had not been expected to have collected much dust because most early dust would have been reused to form new stars.
