Tangled magnetic fields power cosmic particle accelerators
SLAC scientists find a new way to explain how a black hole's plasma jets boost particles to the highest energies observed in the universe. The results could also prove useful for fusion and accelerator research on Earth. Menlo Park, Calif. Magnetic field lines tangled like spaghetti in a bowl might be behind the most powerful particle accelerators in the universe.

Unprecedented Views of the Birth of Planets
Unprecedented Views of the Birth of Planets
Hitherto unknown structures in belts of dust and gas around young stars are providing new insights into the birth of planets along with compelling fodder for research. They were discovered by an international team of astronomers that studied 20 of these so-called protoplanetary discs in a months-long observing campaign.

Rosetta witnesses birth of baby bow shock around comet
Rosetta witnesses birth of baby bow shock around comet
ESA ESA Science Rosetta A new study reveals that, contrary to first impressions, Rosetta did detect signs of an infant bow shock at the comet it explored for two years - the first ever seen forming anywhere in the Solar System. From 2014 to 2016, ESA's Rosetta spacecraft studied Comet 67P/Churyumov-Gerasimenko and its surroundings from near and far.

The Epoch of Planet Formation, Times Twenty
Astronomers have cataloged nearly 4,000 exoplanets in orbit around distant stars. Though the discovery of these newfound worlds has taught us much, there is still a great deal we do not know about the birth of planets and the precise cosmic recipes that spawn the wide array of planetary bodies we have already uncovered, including so-called hot Jupiters, massive rocky worlds, icy dwarf planets, and - hopefully someday soon - distant analogs of Earth.

Taming turbulence: Seeking to make complex simulations a breeze
For News Media FOR IMMEDIATE RELEASE × An improved model for how shear-flow turbulence changes in different systems will more easily address previously intractable problems for understanding phenomena such as star formation and the dynamics of galaxies without the need for expensive supercomputers.

Slow flow for glaciers thinning in Asia
Slow flow for glaciers thinning in Asia
ESA Observing the Earth Space for our climate ESA > Our Activities > Observing the Earth > Space for our climate 10 December 2018 Providing water for drinking, irrigation and power, glaciers in the world's highest mountains are a lifeline for more than a billion people. As climate change takes a grip and glaciers lose mass, one might think that, lubricated by more meltwater, they flow more quickly.

Humans may be reversing the climate clock, by 50 million years
For News Media EMBARGOED UNTIL 12/10/18 at 3 p.m. ET × Our future on Earth may also be our past. In a study published Monday (Dec. 10, 2018) in the Proceedings of the National Academy of Sciences, researchers show that humans are reversing a long-term cooling trend tracing back at least 50 million years.

Largest ever black hole merger detected
Largest ever black hole merger detected
Gravitational waves have been detected after the largest collision of black holes ever observed. The collision took place roughly five billion years ago and produced gravitational waves that were observed on Earth by extremely sensitive detectors on 29 July 2017. The gravitational waves - tiny ripples in space-time that are produced by violent cosmic events - showed that the black holes weighed more than 50 and 34 times the mass of our Sun and collided to produce a single object over 80 times the mass of our star.

Australia leads project to revolutionise astronomy
Australia leads project to revolutionise astronomy
Australian scientists will lead the design phase of a multimillion-dollar project for a new system on one of the world's most powerful ground-based optical telescopes that will produce images up to three times sharper than the Hubble Space Telescope. Two partners in the Australian Astronomical Optics (AAO) consortium - The Australian National University (ANU, AAO-Stromlo) and Macquarie University (AAO-MQ) - will design the new $AU32-million adaptive-optics system, called MAVIS, for one of the 8-metre Unit Telescopes at the European Southern Observatory's Very Large Telescope in Chile.

Pollution : New ammonia emission sources detected from space
Pollution : New ammonia emission sources detected from space
Paris, December 5, 2018 Researchers from the CNRS 1 and the Université Libre de Bruxelles (ULB) have prepared the first global map of the distribution of atmospheric ammonia (NH3) by analyzing measurements taken by satellites between 2008 and 2016. The IASI interferometer developed by the CNES allowed them to catalog more than 200 ammonia sources, two-thirds of which had never been identified before.

Bringing balance to the Universe
A new toy model proposes a way to unify dark energy and dark matter in our Universe. Normal matter is the basic building block of humans, plants, and the solar system, but yet only comprises 5% of all the matter in the Universe. The other 95% is typically invisible, other than when its presence is inferred via gravitational effects.

Scientists detect biggest known black-hole collision
Scientists detect biggest known black-hole collision
An international team of scientists have detected ripples in space and time, known as gravitational waves, from the biggest known black-hole collision that formed a new black hole about 80 times larger than the Sun - and from another three black-hole mergers. ANU is playing a lead role in Australia's involvement with the gravitational wave discovery through a partnership in the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO), which is based in the United States.

Study witnesses first moments of star dying in finest detail
An international research team including The Australian National University (ANU) has used the Kepler space telescope in coordination with ground-based telescopes to witness the first moments of a star dying in unprecedented detail. The astronomers witnessed the star dying a long time ago in a galaxy far, far away, as part of a project that aims to solve the mystery of how stars explode.
