ESA sets clock by distant spinning stars
ESA sets clock by distant spinning stars
ESA's technical centre in the Netherlands has begun running a pulsar-based clock. The 'PulChron' system measures the passing of time using millisecond-frequency radio pulses from multiple fast-spinning neutron stars. Operating since the end of November, this pulsar-based timing system is hosted in the Galileo Timing and Geodetic Validation Facility of ESA's ESTEC establishment, at Noordwijk in the Netherlands, and relies on ongoing observations by a five-strong array of radio telescopes across Europe.

Young star caught forming around another star
A small star has been observed forming out of the dust surrounding a larger star, in a similar way to how planets are born. Astronomers were observing the formation of a massive young star, called MM 1a, when they discovered an unexpected object nearby. MM 1a is surrounded by rotating disc of gas and dust.

University apprenticeship scheme awarded
Researchers from the LIGO and Virgo Collaborations have announced gravitational wave observations of four new binary black holes and released their first catalogue of gravitational wave events. Since the detectors first started operation in September 2015 , the LIGO and Virgo Collaborations, which include researchers from the University of Birmingham, have completed two observation runs.

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.

Fake plastic atoms
Fake plastic atoms
ESA > Our Activities > Human Spaceflight > International Space Station Our world is made of atoms and molecules, but even with the most powerful microscopes we can only see snapshots, never how they move and interact with each other. To model how atoms behave, researchers have been using plastic particles in weightlessness and the latest batch of results are returning to Earth with ESA astronaut Alexander Gerst in a Soyuz spacecraft on Thursday.

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.

Starburst galaxies and blast injuries: News from the College
Here's a batch of fresh news and announcements from across Imperial. From new insights into star formation, to an annual blast injury conference, here is some quick-read news from across the College. Extreme starburst galaxies Current theories predict a maximum amount of stars that a galaxy can produce each year.

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.
