The Largest Structure in the Observable Universe

The largest known structure in the universe has been discovered by an international team of astronomers. The large quasar group (LQG -a portion shown above)) is so large that it would take a vehicle traveling at the speed of light some 4 billion years to cross it.

"While it is difficult to fathom the scale of this LQG, we can say quite definitely it is the largest structure ever seen in the entire universe," said Dr Clowes of University of Central Lancashire’s Jeremiah Horrocks Institute. “This is hugely exciting – not least because it runs counter to our current understanding of the scale of the universe. Even travelling at the speed of light, it would take 4 billion years to cross. This is significant not just because of its size but also because it challenges the Cosmological Principle, which has been widely accepted since Einstein. Our team has been looking at similar cases which add further weight to this challenge and we will be continuing to investigate these fascinating phenomena.”

Fat or flat: Getting galaxies into shape

Australian astronomers have discovered what makes some spiral galaxies fat and bulging while others are flat discs—and it’s all about how fast they spin.

The research, led by the International Centre for Radio Astronomy Research (ICRAR) in Perth, found that fast-rotating spiral galaxies are flat and thin while equally sized galaxies that rotate slowly are fatter.

The study was published today in the prestigious Astrophysical Journal and was part of “The Evolving Universe” research theme of the ARC Centre of Excellence for All-sky Astrophysics (CAASTRO).

Mystery Solved: How Huge Young Stars Hang On to Gas

After decades of wondering why young massive stars don’t blow away the gas surrounding them, astronomers have finally found a process that explains how these stellar youngsters hang on to their gassy envelopes.

This star type — more than 10 times the mass of the sun and most active in ultraviolet light — begins shining as a gigantic gas cloud collapses, fusing hydrogen into helium and igniting the star’s nuclear engine. The new research shows that this gas accretion continues even as the star shines, counteracting the stellar radiation that “pushes” against the gas.
