The instability at the beginning of the solar system

Scientists have unveiled a new theory that could help solve a galactic mystery of how our solar system evolved. Specifically, how did the gas giants - Jupiter, Saturn, Uranus and Neptune - end up where they are, orbiting the sun like they do?

More evidence that the building blocks of life on Earth came from meteorites

There is more evidence that the building blocks of life on Earth came from meteorites, according to researchers, who analysed three carbon-rich meteorites and found evidence of multiple compounds needed for DNA or RNA. Using state-of-the-art analytical techniques on the meteorites, they found guanine, adenine, uracil, cytosine, and thymine molecules which may have served as building blocks of life on Earth.

Classifying exoplanet atmospheres opens new field of study

An international team of researchers examined data for 25 exoplanets and found some links among the properties of the atmospheres, including the thermal profiles and chemical abundances in them. This marks the first time exoplanet atmospheres have been studied as populations, rather than individually.

A roadmap for deepening understanding of a puzzling universal process

A puzzling process called magnetic reconnection triggers explosive phenomena throughout the universe, creating solar flares and space storms that can take down mobile phone service and electrical power grids. Now scientists have detailed a roadmap for untangling a key aspect of this puzzle that could deepen insight into the workings of the cosmos.

Giant stars undergo dramatic weight loss program

Astronomers have found a slimmer type of red giant star for the first time. These stars have undergone dramatic weight loss, possibly due to a greedy companion. The discovery is an important step forward to understanding the life of stars in the Milky Way.

MAGIC telescopes observe nova explosion shining brightly in gamma rays at extremely high energy

The MAGIC telescopes have observed the nova RS Ophiuchi shining brightly in gamma rays at extremely high energy. The Gamma rays emanate from protons that are accelerated to very high energies in the shock front following the explosion. This suggests that novae are also a source of the ubiquitous cosmic radiation in the universe which consists mainly of protons rich in energy, which race through space at almost the speed of light.
