A century of galaxy discrimination revealed by giant European astronomy survey
A huge European astronomy survey, whose results are released today (21 December 2017), has revealed that the view of the Universe provided by traditional optical telescopes is seriously biased. The Herschel ATLAS (H-ATLAS) was a survey carried out by an international team led by researchers at Cardiff University with European Herschel Space Observatory in the far-infrared waveband, which consists of electromagnetic waves with wavelengths 200 times greater than optical light.

Sunlight holds the key to planet’s shine
Scientists have discovered how the sun's influence on the remote planet Uranus changes its brightness in the sky. Changes in solar activity influence the colour and formation of clouds around the planet, researchers at Oxford and Reading universities found. The icy planet is second furthest from the sun in the solar system and takes 84 Earth years to complete a full orbit - one Uranian year.

Mars: Not as dry as it seems
Image shows modern Mars (left) dry and barren, compared with the same scene over 3.5 billion years ago covered in water (right). The rocks of the surface were slowly reacting with the water, sequestering it into the Martian mantle leading to the dry, inhospitable scene shown on the left. Image credit: Jon Wade When searching for life, scientists first look for an element key to sustaining it: fresh water.

Massive primordial galaxies found nestling in vast halo of dark matter
Two giant galaxies seen when the universe was only 780 million years old, or about 5% of its current age, have been identified by an international team involving UCL scientists using the Atacama Large Millimeter/submillimeter Array (ALMA). The latest observations push back the epoch of massive-galaxy formation and reveal that these uncommonly large galaxies are nestled inside an even larger cosmic structure, a halo of dark matter several trillion times bigger than the sun.

Can citizen scientists locate the world’s seagrass?
Citizen scientists have the potential to secure a future for seagrass meadows by collecting new data about the meadows globally, according to the lead author of a new study and a scientific adviser for BBC's Blue Planet II . Led by Cardiff University's Sustainable Places Research Institute along with Swansea University and James Cook University in Australia, the study suggests that citizen scientists may be key to helping answer global questions about seagrass meadows, their location, health, reproductive status and associated fauna.

Hunt for dark matter is narrowed by new University of Sussex research
Hunt for dark matter is narrowed by new University of Sussex research Scientists at the University of Sussex have disproved the existence of a specific type of axion - an important candidate 'dark matter' particle - across a wide range of its possible masses. The data were collected by an international consortium, the Neutron Electric Dipole Moment (nEDM) Collaboration, whose experiment is based at the Paul Scherrer Institut in Switzerland.

Vitamin D linked to better live birth rates in women undergoing assisted reproduction treatment
An international team of astronomers have discovered, for the first time, observational evidence in how some features at the surface of the hot massive supergiant star 'Zeta Puppis' induce the formation of fundamental structures in its wind. In contrast to cool low-mass stars like the Sun, hot massive stars are scarce, possess extremely strong winds, and catastrophically end their lives as supernovae that stir up and enrich the interstellar medium with chemical elements involved in the creation of new stars and even planets like Earth.

Call for Europe-wide screening of babies for heart defects
For the first time, scientists have directly detected gravitational waves - ripples in space and time - in addition to light from the spectacular collision of two neutron stars. This is the first time that astronomers have been able to study the same event with both gravitational waves and light. The discovery was made using the U.S.-based Laser Interferometer Gravitational-Wave Observatory (LIGO); the Europe-based Virgo detector, and some 70 groundand space-based observatories.

First coast-to-coast land motion map of Scotland derived from satellite radar images
The first country-wide map of relative land motion has been created by a team at the University of Nottingham. Using hundreds of satellite radar images the team, working with Geomatic Ventures Limited (GVL), an innovative University spin-out company, created a complete map of mainland Scotland. The map covers a two-year period from 2015 to 2017 and was created using Intermittent Small Baseline (ISBAS) analysis, a novel satellite remote sensing technique.

New research uncovers 90 million years of history of Martian volcano
Analysis of Martian meteorites has uncovered 90 million years' worth of new information about one of the red planet's volcanoes - and helped pinpoint which volcano the meteorites came from. Geologists based in the UK and the USA have used advanced mass spectrometry techniques to learn more about the origins of six meteorites known as 'nakhlites' - pieces of Martian terrain which were blasted from the face of the red planet by an impact event 11 million years ago, then drifted through space before landing on Earth.
