For example, astronomers have been trying to explain why some recently discovered distant, but young, galaxies contain massive amounts of dust.

Using the Very Large Array of the National Radio Astronomy Observatory in the US, the team observed radio emission from hydrogen in a distant galaxy and found that it would have contained billions of young, massive stars surrounded by clouds of hydrogen gas.

«The fact that we see young galaxies in the distant universe that have already shut down star formation is remarkable.»

«Not only did we detect radio signals emitted by distant galaxies when the Universe was three billion years younger, but their gas reservoirs turned out to be unexpectedly large, about 10 times larger than the mass of hydrogen in our Milky Way.

But around the same time studies of very distant galaxies, which we see as they were when the Universe was very young, were setting constraints on the amount of baryonic matter in the Universe (New Scientist, Science, 30 April).

Astronomers have discovered five full - sized galaxies in the extremely distant — and therefore extremely young — universe.

An international team studying gas clouds in a distant galaxy has found that the temperature of the gas matches almost exactly what models predicted for the young cosmos.

Quasars are young galaxies powered by massive black holes, extremely bright, extremely distant, and thus highly redshifted.

These extremely young, extremely distant galaxies blast out as much light as the entire Milky Way, all from a core that is a millionth the Milky Way's diameter.

The most important targets include the most distant (i.e., the youngest) galaxies as they emerged in the early Universe.

Gillian Wilson, professor of physics and astronomy at UC Riverside, added, «Fascinatingly, however, the study found that the percentage of galaxies which had stopped forming stars in those young, distant clusters, was much lower than the percentage found in much older, nearby clusters.

This estimate takes into account the fact that the ultraviolet irradiance of the Sun was considerably larger in the distant past, as confirmed by astronomical measurements of younger Sun - like stars in the nearby galaxy.

But direct evidence of a supernova's dust ‐ making capabilities has been slim up to now, and could not account for the copious amount of dust detected in young, distant galaxies.
