New research provides evidence of strong early magnetic field around Earth

Deep within Earth, swirling liquid iron generates our planet’s protective magnetic field. This magnetic field is invisible but is vital for life on Earth’s surface: it shields the planet from harmful solar wind and cosmic rays from the sun. Given the importance of the magnetic field, scientists have been trying to figure out how the … Read more New research provides evidence of strong early magnetic field around Earth

Infrared detection of aliphatic organics on a cometary nucleus

An accurate refinement of the quality of the data on the surface composition of the nucleus of the comet 67P Churyumov Gerasimenko collected by the Italian spectrometer VIRTIS, on board the European space mission Rosetta, has allowed to identify, the first time for a comet, clear traces of aliphatic organic compounds, chains of carbon and … Read more Infrared detection of aliphatic organics on a cometary nucleus

Magnetic storms discovered to originate much closer to Earth than previously thought

Magnetic storms are the primary drivers of extreme space weather around our planet, visible as the northern and southern auroral lights. Despite their importance and potential hazards to space and ground infrastructure, the process that powers storms has not been understood yet because they are far too dynamic and complex to study with single satellites. … Read more Magnetic storms discovered to originate much closer to Earth than previously thought

Astronomers witness a “heat-wave” of thermal energy radiating outward from a high-mass protostar

Our Galaxy is populated with billions of bright stars that have masses equivalent from ten to many tens the mass of the Sun. Despite their short and turbulent existence, these stars play a paramount role in astrophysics. For example they forge metals and more heavier chemical elements and eject them into space at the end … Read more Astronomers witness a “heat-wave” of thermal energy radiating outward from a high-mass protostar

UBC researcher studies yeast to protect astronauts from space radiation

Corey Nislow is not an astronaut, but if humanity makes it to Mars safely, he will have played a vital role. In his lab at UBC, he’s working to develop drugs and other treatments that can protect space mission crews from the impact of cosmic radiation. “Outside Earth’s protective atmosphere, mission crew are exposed to … Read more UBC researcher studies yeast to protect astronauts from space radiation

CNRS: Mars’ water could disappear faster than expected

The small red planet is losing water more quickly than what theory as well as past observations would suggest. The gradual disappearance of water (H2O) occurs in the upper atmosphere of Mars: sunlight and chemistry disassociate water molecules into hydrogen and oxygen atoms that the weak gravity of Mars cannot prevent from escaping into space. … Read more CNRS: Mars’ water could disappear faster than expected

New map of Milky Way reveals giant wave of stellar nurseries

Astronomers at Harvard University have discovered a monolithic, wave-shaped gaseous structure – the largest ever seen in our galaxy – made up of interconnected stellar nurseries. Dubbed the “Radcliffe wave” in honor of the collaboration’s home base, the Radcliffe Institute for Advanced Study, the discovery transforms a 150-year-old vision of nearby stellar nurseries as an … Read more New map of Milky Way reveals giant wave of stellar nurseries

A repeating Fast Radio Burst from a spiral galaxy deepens the mystery of where these signals originate from

At this point in time, one of the greatest mysteries in astronomy is where short, dramatic bursts of radio light seen across the universe, known as Fast Radio Bursts (FRBs), are originating from. Although FRBs last for only a thousandth of a second, there are now hundreds of records of these enigmatic sources. However, from … Read more A repeating Fast Radio Burst from a spiral galaxy deepens the mystery of where these signals originate from

A thick crustal block revealed by reconstructions of early Mars highlands

The highlands of the southern hemisphere of the planet Mars are considered to be homogenous land whose origin dates back more than four billion years. A team of French and American planetary scientist led by Sylvain Bouley, (GEOPS – Université Paris-Saclay / CNRS), involving researchers from the University of Toulouse, the Paris Observatory, the University … Read more A thick crustal block revealed by reconstructions of early Mars highlands
