|Shedding light on the science of auroral breakups
Posted: 08 Feb 2019 06:56 AM PST
Scientists have quantitatively confirmed how energetic an auroral breakup can be. Using a combination of cutting-edge ground-based technology and new space-borne observations, they have demonstrated the essential role of an auroral breakup in ionizing the deep atmosphere. The research furthers our understanding of one of the most visually stunning natural phenomena.

3.5 billion years ago Earth hosted life, but was it barely surviving, or thriving? A new study led by researchers at the Earth-Life Science Institute of Tokyo Tech provides new answers to this question. Microbial metabolism is recorded in billions of years of sulfur isotope ratios that agree with this study’s predictions, suggesting life throve in the ancient oceans. Using this data, scientists can more deeply link the geochemical record with cellular states and ecology.

A team of scientists has visualized meteorite components at resolution powers much higher than ever before. Their efforts resulted in a much better look at — and enhanced understanding of — substances inside carbonaceous chondrites, the organic-containing meteorites that land on Earth. These substances include hydrogen, carbon, nitrogen and water, all of which are needed for life.

|Liberal sprinkling of salt discovered around a young star
Posted: 07 Feb 2019 08:49 AM PST
New ALMA observations show there is ordinary table salt in a not-so-ordinary location: 1,500 light-years from Earth in the disk surrounding a massive young star. Though salts have been found in the atmospheres of old, dying stars, this is the first time they have been seen around young stars in stellar nurseries. The detection of this salt-encrusted disk may help astronomers study the chemistry of star formation as well as identify other similar protostars hidden inside dense cocoons of dust and gas.
