It Takes the Right Amount of Carbon
It Takes the Right Amount of Carbon
The element carbon and its compounds form the basics for life on Earth. Short-duration flash-heating events in the solar nebula prior to the formation of planets in our solar system were responsible for supplying the Earth with a presumably ideal amount of carbon for life and evolution. This shows a carbon chemistry model developed by Heidelberg University researchers.

The volatile processes that shaped Earth
Based on observations of newly-forming stars, scientists know that the solar system began as a disc of dust and gas surrounding the centrally-growing sun. The gas condensed to solids which accumulated into larger rocky bodies like asteroids and mini-planets. Over a period of 100 million years these mini-planets collided with one another and gradually accumulated into the planets we see today, including the Earth.

Searching for distant worlds with a flying telescope
Searching for distant worlds with a flying telescope
Media releases, information for representatives of the media Media Relations (E) Researchers from the University of Bern, using an observatory on board a jumbo jet, have observed how the extrasolar Planet GJ 1214b is passing in front of its star, causing a kind of mini-eclipse. The first measurements of this kind with the observatory called SOFIA (short for Stratospheric Observatory for Infra-red Astronomy) prove that the flying observatory is well-suited to the observation of exoplanets.

IceCube helps demystify strange radio bursts from deep space
IceCube is a neutrino detector composed of 5,160 optical modules embedded in a gigaton of crystal-clear ice a mile beneath the geographic South Pole. Photo courtesy of National Science Foundation For a decade, astronomers have puzzled over ephemeral but incredibly powerful radio bursts from space. The phenomena, known as fast radio bursts or FRBs, were first detected in 2007 by astronomers scouring archival data from Australia's Parkes Telescope, a 64-meter diameter dish best known for its role receiving live televison images from the Apollo 11 moon landing in 1969.

Finds GPs are unwilling to refer patients for bowel cancer checks
Physicists have described how observations of gravitational waves limit the possible explanations for the formation of black holes outside of our galaxy; either they are spinning more slowly than black holes in our own galaxy or they spin rapidly but are ‘tumbled around' with spins randomly oriented to their orbit.

Fast Radio Bursts May Be Firing Off Every Second
Fast Radio Bursts May Be Firing Off Every Second
When fast radio bursts, or FRBs, were first detected in 2001, astronomers had never seen anything like them before. Since then, astronomers have found a couple of dozen FRBs, but they still don't know what causes these rapid and powerful bursts of radio emission. For the first time, two astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) have estimated how many FRBs should occur over the entire observable universe.

Size matters in the detection of exoplanet atmospheres
Size matters in the detection of exoplanet atmospheres
A group-analysis of 30 exoplanets orbiting distant stars suggests that size, not mass, is a key factor in whether a planet's atmosphere can be detected according to a UCL-led team of European researchers. The largest population-study of exoplanets to date successfully detected atmospheres around 16 'hot Jupiters', and found that water vapour was present in every case.

Bidding farewell to Cassini mission that explored Saturn
Bidding farewell to Cassini mission that explored Saturn
Scientists led the development of two scientific sensors on NASA's spacecraft Cassini. "It's an extraordinarily difficult mission, but one with extraordinary rewards: giving us a glimpse into how our solar system formed and how it operates today. Watching a mission come to an end is always bittersweet, but we're proud to have been a part of something so successful that will continue to inform our understanding of our universe." Los Alamos National Laboratory played part in two major discoveries and powered the spacecraft during its 20-year flight Los Alamos, N.M., Sept.

Discovery of boron on Mars adds to evidence for habitability
The discovery of boron on Mars gives scientists more clues about whether life could have ever existed on the planet. "Because borates may play an important role in making RNA-one of the building blocks of life-finding boron on Mars further opens the possibility that life could have once arisen on the planet," said Patrick Gasda.

Does the organic material of comets predate our Solar System ?
Does the organic material of comets predate our Solar System ?
The Rosetta space probe discovered a large amount of organic material in the nucleus of comet “Chury.” In an article published by MNRAS on August 31, 2017, two French researchers advance the theory that this matter has its origin in interstellar space and predates the birth of the Solar System. The ESA's Rosetta mission, which ended in September 2016, found that organic matter made up 40% (by mass) of the nucleus of comet 67P Churyumov-Gerasimenko, a.k.a.
