Unlocking the secrets of the universe’s brightest galaxies

27 September 2015 Astronomy Now

Submillimetre galaxies (SMGs) are the brightest galaxies in the universe, yet invisible to the naked eye. But look through an infrared telescope, and they light up the sky. They are probably 12 or 13 billion years old, and what makes them so luminous is that they form stars very quickly — 1000 times faster than our Milky Way.

Citizen scientists discover gravitational lenses via Space Warps project

26 September 2015 Astronomy Now

Around 37,000 citizen scientists combed through 430,000 images to help an international team of researchers to discover 29 new gravitational lens candidates through Space Warps — an online classification system which guides citizen scientists to become lens hunters, giving the public a chance to make their own scientific discoveries.

‘Stealth dark matter’ theory may explain universe’s missing mass

25 September 2015 Astronomy Now

A Lawrence Livermore National Laboratory team has combined theoretical and computational physics techniques using the Laboratory’s 2-petaflop Vulcan supercomputer to devise a new model of dark matter. They found that dark matter is “stealthy” today, but would have been easy to detect in the extremely high-temperature plasma conditions that pervaded the early universe.

Secrets behind Pluto’s pastels far from being answered

24 September 2015 Stephen Clark

Geologists said Thursday they are bewildered by images from NASA’s New Horizons spacecraft baring unseen landscapes on Pluto with unexpected “snakeskin” textures, colourful chasms routing through ancient landforms, and vivid new views of apparent glacial flows.
