Australian astronomers have been awarded time on the European Southern Observatory’s Very Large Telescope (VLT).
It will enable them to lead international teams of astronomers to perform deep observations of the Milky Way’s galactic cousins and reveal the physics of star formation and galaxy evolution in some of the most massive structures in the Universe.
The projects are led by Jesse van de Sande from the University of Sydney, and by Barbara Catinella and Luca Cortese from the International Centre for Radio Astronomy Research at the University of Western Australia. The VLT is in the Atacama Desert of northern Chile, one of the driest places in the world.

They’re using Webb to look for the first stars, the first galaxies, baby planets, massive black holes.
Over the past 30 years, Hubble has transformed science and culture, revealing a Universe of 200 billion galaxies. Webb will see further, solving today’s mysteries and creating new ones.
On Tuesday morning Joe Biden will release ‘the first picture’ then NASA will release a suite of images early Wednesday morning from the James Webb Space Telescope, the successor to Hubble.
Nearly 40 researchers across Australia are eagerly awaiting data from web for their projects. Many of them are available to talk on Tuesday about what they hope to see with Webb and about their reaction to the first pictures.
Much of the Webb data is flowing back to Earth through Tidbinbilla, and some comes from an instrument designed by Peter Tuthill at the University of Sydney. He is relieved and excited. “This is a day I have been looking forward to for a big part of my career. Everything about the Webb is so over-the-top audacious – from the titanic articulated mirror down to its orbit out in the cold voids of interplanetary space.”
Cognition is influenced by siblings, researchers find.
Autistic children with autistic siblings have better
cognition than those who are the only family member with the condition, researchers
Importantly, the outcome does not depend on birth order.
Although previous studies have identified that having
autistic siblings leads to better cognition for individual children with the
condition, it was assumed that the order in which the children were born was a
Filtering out social bots can help critical response teams see what’s
happening in real time
Researchers have created an algorithm that distinguishes
between misinformation and genuine conversations on Twitter, by detecting
messages churned out by social bots.
Dr Mehwish Nasim and colleagues at the School of Mathematical
Sciences at the University of Adelaide say the algorithm will make it easier
for emergency services to detect major events such as civil unrest, natural
disasters, and influenza epidemics in real time.
“When something really big is going on, people tweet a
huge amount of useful information,” says Mehwish.
Researchers hunt for a 12-billion-year-old signal that marks the end of the post Big Bang “dark age”.
