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.

Hubble confirms largest comet nucleus ever seen

The nucleus is about 50 times larger than found at the heart of most known comets. Its mass is estimated to be a staggering 500 trillion tons, a hundred thousand times greater than the mass of a typical comet found much closer to the Sun.

Astronomers capture surprising changes in Neptune's temperatures

An international team of astronomers have used ground-based telescopes, including the European Southern Observatory's Very Large Telescope, to track Neptune's atmospheric temperatures over a 17-year period. They found a surprising drop in Neptune's global temperatures followed by a dramatic warming at its south pole.

Astronomers discover a new type of freak stars covered in helium burning ashes

While normal stars have surfaces composed of hydrogen and helium, the newly discovered stars have their surfaces covered with carbon and oxygen, the ashes of He-burning - a very exotic composition for a star. The situation becomes more puzzling because the new stars have temperatures and radii that indicate they are still burning helium in their cores.

10 new gravitational waves found in LIGO-Virgo's O3a data

Astrophysicists re-examined LIGO-Virgo's O3a data and found 10 additional black hole mergers, all outside the detection threshold of the original analysis. The new mergers hint at exotic astrophysical scenarios that, for now, are only possible to study using gravitational wave astronomy.
