Orbits of ancient stars prompt rethink on Milky Way evolution

Australian telescopes and European satellite combine to reveal unexpected motions among the Galaxy’s rarest objects

Theories on how the Milky Way formed are set to be rewritten following discoveries about the behaviour of some of its oldest stars.

An investigation into the orbits of the Galaxy’s metal-poor stars – assumed to be among the most ancient in existence – has found that some of them travel in previously unpredicted patterns.

Astronomers see ‘cosmic ring of fire’, 11 billion years ago

Unusual galaxy set to prompt rethink on how structures in the Universe form

Full paper, Full video, and images available. Details below.

Astronomers have captured an image of a super-rare type of galaxy – described as a “cosmic ring of fire” – as it existed 11 billion years ago.

The galaxy, which has roughly the mass of the Milky Way, is circular with a hole in the middle, rather like a titanic doughnut. Its discovery, announced in the journal Nature Astronomy, is set to shake up theories about the earliest formation of galactic structures and how they evolve.

Hungry galaxies grow fat on the flesh of their neighbours

Modelling shows big galaxies get bigger by merging with smaller ones

Galaxies grow large by eating their smaller neighbours, new research reveals.

Exactly how massive galaxies attain their size is poorly understood, not least because they swell over billions of years. But now a combination of observation and modelling from researchers led by Dr Anshu Gupta from Australia’s ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) has provided a vital clue.

Baby blue-tongues are born smart

Australian research finds little lizards learn very quickly.

Young Australian eastern blue-tongue lizards (Tiliqua scincoides) are every bit as clever as adults, researchers have found.

Life is hard for baby blue-tongues. As soon as they are born, they are on their own, with neither parental support nor protection. Adults of the species can grow to 600 millimetres long and enjoy the benefits of thick scales and a powerful bite, but the young are much smaller and thus more vulnerable to predation.

And that means they have to box clever if they are to survive.

The L’Oréal Foundation and the UNESCO recognise five exceptional women scientists with the 2011 For Women In Science awards

Australian professor Jillian Banfield honoured as the 2011 Laureate for North America

November 11, 2010: Professor Ahmed Zewail, President of the L’Oréal-UNESCO For Women in Science Awards Jury, today announced the five Laureates of the 2011 program.  Each year, five outstanding women scientists – one per region – are honoured for the contributions of their research, the strength of their commitments and their impact on society.  With the Marie Curie Nobel Centenary being celebrated in 2011, this year the For Women in Science program has a particularly strong resonance, placing women and chemistry at the heart of science today.

The awards ceremony will take place on March 3, 2011 at UNESCO Headquarters in Paris.  Each Laureate will receive US$100,000 in recognition of her contributions to science.
