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 Universitť 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.

Galileo satellites prove Einstein’s Relativity Theory to highest accuracy yet
ESA Navigation EGNOS Galileo Evolution NAVISP 4 December 2018 Europe's Galileo satellite navigation system - already serving users globally - has now provided a historic service to the physics community worldwide, enabling the most accurate measurement ever made of how shifts in gravity alter the passing of time, a key element of Einstein's Theory of General Relativity.

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
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.

Scientists inch closer to revealing mysteries of Red Planet
The 300-million-mile journey that culminated in NASA's InSight landing on Mars this week represents a major scientific coup for all involved, including mission participants from the University of Bristol. The £635m lander, which came to rest on Mars on Monday, will study the makeup and dimensions of the Red Planet's core.

Marsquakes’ mission successfully lands on Red Planet
A mission to Mars which carries instruments co-designed by Oxford scientists, has successfully landed and will soon begin the first study of the heart of the planet. The NASA InSight mission landed shortly after 19:50 GMT on Monday, 26 November. InSight will study the inside of Mars to learn how planets, moons and meteorites with rocky surfaces, including the Earth and its Moon, formed.

Study brings new climate models of small star TRAPPIST 1’s seven intriguing worlds
Not all stars are like the sun, so not all planetary systems can be studied with the same expectations. New research from a University of Washington-led team of astronomers gives updated climate models for the seven planets around the star TRAPPIST-1. The work also could help astronomers more effectively study planets around stars unlike our sun, and better use the limited, expensive resources of the James Webb Space Telescope , now expected to launch in 2021.

Finding rules in the chaos that could help reveal secrets of the Big Bang
New research has revealed that non-equilibrium quantum systems do obey universal laws, a discovery that can bring us closer to revealing the secrets of the Big Bang. Researchers from the University of Nottingham joined teams at the Technical University of Vienna and the University Heidenberg to undertake It shows that when quantum particles whirl around they obey universal laws, meaning what is true for one quantum system is also true for others.
