Primitive meteorites formed in less turbulent solar nebula, researchers suggest
Chondritic meteorites (chondrites) are some of the oldest rocks in our solar system, forming 4.5 billion years ago. Therefore, their primitive composition means that they offer a window into the origins of planet formation, ...
ALMA observations explore the nuclear structure of a dusty star-forming galaxy
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have observed a dusty star-forming galaxy known as SPT 0538−50. Results of the observational campaign, presented Dec. 4 on the arXiv pre-print server, ...
Observations suggest sun-like stars emit superflares once per century
There is no question that the sun is a temperamental star, as this year's unusually strong solar storms show. Some of them led to remarkable auroras even at low latitudes. But can our star become even more furious?
