(University of Nottingham) Astronomers at the University of Nottingham have identified a type of galaxy that could be the missing link in our understanding of galaxy evolution.

Using a powerful radio telescope to peer into the early universe, a team of California astronomers has obtained the first direct measurement of a nascent galaxy's magnetic field as it appeared 6.5 billion years ago.

The Milky Way contains a disk of "dark matter," according to new calculations by astronomers. They have used the results of a supercomputer simulation to deduce the presence of this disk.

(ESO) Astronomers from around the world combined data from ground- and space-based telescopes to paint a detailed portrait of the brightest explosion ever seen.

The observations reveal that the jets of the gamma-ray burst called GRB 080319B were aimed almost directly at the Earth.

(ESO) Astronomers have been able to study planet-forming discs around young Sun-like stars in unsurpassed detail, clearly revealing the motion and distribution of the gas in the inner parts of the disc.

This result, which possibly implies the presence of giant planets, relies on the use of a very clever method enabled by ESO's Very Large Telescope.

Astronomers have caught multiple massive galaxies in the act of merging about 4 billion years ago. This discovery, made possible by combining the power of the best ground- and space-based telescopes, uniquely supports the favoured theory of how galaxies form.

Astronomers were able for the first time to witness the appearance of a shell of dusty gas around a star that had just erupted, and follow its evolution for more than 100 days.

This provides the astronomers with a new way to estimate the distance of this object and obtain invaluable information on the operating mode of stellar vampires, dense stars that suck material from a companion.

(Astronomy & Astrophysics) Using observations from the Venus Express spacecraft, an international team of astronomers presents the first detection of hydroxyl in the atmosphere of Venus through its nightglow emission.

Observing atmospheric airglow is a major tool for inferring the composition and chemistry of the upper planetary atmospheres.

These results will be published in Astronomy & Astrophysics.
