Scientists from Western Sydney University and CSIRO found dancing ghosts deep in the cosmos as part of the first deep sky search utilising CSIRO's ASKAP (Australian Square Kilometre Array Pathfinder) radio telescope.

Winds from two active supermassive black holes at a distance of approximately a billion light-years are producing them, according to scientists.

PKS 2130-538 is the name given to them, and nothing is known about them.

While the 'ghosts' and the two radio galaxies assumed to be responsible for their creation have been spotted previously, none have been caught in such detail.&nbsp;

As a result, the finding was claimed to have been accepted for publication in the Australian Astronomical Society's publications (PASA).

He says that it is one of several that have been provided after extensive research.

Ray Norris, of Western Sydney University and CSIRO, the study's principal author, stated that it came as a complete surprise to the EMU team.&nbsp;

The most well-known radio sources are active supermassive black holes at galaxies' cores.

This is because material is channelled around the perimeter of the event horizon via magnetic field lines and blasted away from the poles in the form of radio-loud jets as these black holes consume stuff.&nbsp;

Never seen before: Dancing 'cosmic ghosts' discovered by astronomers

The experts at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia's&nbsp;national science agency, have created a&nbsp;new atlas of the universe.

Experts at the agency have&nbsp;mapped three million galaxies with more details and in a&nbsp;record time of 300 hours, in comparison to previous mappings which have taken years.

The report claims the scientists at the agency were able to create a new atlas of the universe with almost three million galaxies in forms of pictures revealing twice the detail of the previous images. The data around this new discovery is publically available and can help fellow scientists to study "everything from star formation to how galaxies and their super-massive black hole evolve and interact," the lead author Dr David McConnell said.

"We expect to find tens of millions of new galaxies in future surveys," he added.

This has been possible due to the&nbsp;Australian Square Kilometre Array Pathfinder (Askap) which is a collection of 36 dish antennas that work in coordination to capture panoramic views of the sky.

Spread across an area of 6km&nbsp;(3.7 miles)&nbsp;at the CSIRO's Murchison observatory about 700km north of Perth (Australia),&nbsp;this telescope combines signals from the smaller dishes and then creates&nbsp;high-resolution images for the scientists to study. The whole process is, however, costing a fraction of what a large dish usually costs, CSIRO claimed.

For the first time, Askap conducted an&nbsp;all-sky survey and covered 83 per cent of the sky. Using the technology, scientists were able to combine&nbsp;903 high-resolution and&nbsp;detailed images. The scientists hope to find answers to the structuring and evolution of the Earth.

Australian scientists create 'a new atlas' by mapping millions of galaxies

Thousands were expected to rally in Sydney on Wednesday to demand urgent climate action from Australia's government, as <a href="https://www.wionews.com/world/sydneysiders-urged-to-stay-indoors-as-australian-bushfire-smoke-blankets-city-263900">bushfire smoke</a> choking the city caused health problems to spike.

Smoke alarms rang out across Australia's biggest city Tuesday with thick haze from bushfires burning along the country's east coast forced buildings to be evacuated, school children to be kept indoors, and ferries to be cancelled.

Sydney has endured weeks bathed in<a href="https://www.wionews.com/world/climate-protests-kick-off-in-smoke-covered-sydney-265149"> toxic smoke</a> as hundreds of blazes have raged across the countryside, with hospitals recording a 25 per cent increase in the number of people visiting emergency departments last week.

The devastating fires have focused attention on&nbsp;<a href="https://www.wionews.com/videos/climate-change-takes-a-toll-on-sydney-264029">climate change</a>, with scientists saying the blazes have come earlier and with more intensity than usual due to global warming and a prolonged drought.

At least 5,000 people were expected at Wednesday's protest, according to organiser Chloe Rafferty, who said the bushfires and smoke haze had created anger at the conservative government's inaction on curbing emissions.

"I think the wider public can see that we are not expecting the climate crisis in the future but we are facing the climate crisis now," she told AFP.

"People are experiencing it in their day-to-day lives."

As well as a rise in people visiting hospitals with smoke-related health symptoms, the number of emergency calls for ambulances spiked 30 per cent last week.&nbsp;

"For most people, smoke causes mild symptoms like sore eyes, nose, and throat," top health department official Richard Broome said.

"However, people with conditions like asthma, emphysema, and angina are at greater risk because the smoke can trigger their symptoms."

Smoke from bushfires is one of the biggest contributors to <a href="https://www.wionews.com/world/australia-bushfires-record-air-pollution-numbers-recorded-in-new-south-wales-sydney-chokes-263757">air pollution in Australia</a>, releasing fine particles that can lodge deep within people's lungs and cause "severe" health impacts over time, according to scientist Mick Meyer from government-funded scientific research agency CSIRO.

"The impact of smoke on people remote from the fires may, on occasion, substantially exceed the direct injury to people within the fire zone," he wrote in The Conversation.

"But we currently lack the operational tools to understand the extent of these impacts or to manage them."

Six people have been killed and more than 700 houses destroyed&nbsp;in bushfires this fire season.

Though the human toll has been far lower than the deadliest fire season in 2009 when almost 200 people died the scale of this year's devastation has been widely described as unprecedented.

Three million hectares (7.4 million acres) of land has been burnt the size of some small countries and vast swathes of koala habitat scorched.

Official data shows 2019 is on track to be one of the hottest and driest years on record in Australia.
