Celebrating 10 Years of Gravitational Waves! Last week, OzGrav hosted a two-day workshop at Swinburne to mark a decade since the first detection of gravitational waves, GW150914, a discovery that reshaped astrophysics and confirmed Einstein’s prediction. Here’s to the next decade of discovery!

This happened 10 years ago, and it was weird! GW150914 was the first ever detection of gravitational waves, when two black holes collided, sending ripples through space. youtube.com/shorts/_GEr2...

A decade ago, we heard the universe for the first time. Gravitational waves changed physics forever. Here’s how Australia helped make it happen. 🎓 Discover the story in our new documentary: youtu.be/n12Ml1sI2Kw

A new gravitational wave event rocked detectors almost 10 years after the first detection. But this time, it was up to four times as loud thanks to a decade of upgrades. OzGrav Associate Investigator Dr Simon Stevenson explains more in The Conversation: theconversation.com/10-years-ago...

Ten years ago, we heard the universe for the first time. Now, we’ve heard it again... only louder. OzGrav researchers, Neil Lu, PhD student at the Australian National University (ANU), and Teagan Clarke, PhD student at Monash University, explain! youtube.com/shorts/edkqk...

New in Nature Astronomy: An international study co-authored by OzGrav’s Prof Ilya Mandel reveals massive stars are just as likely to form in close binaries in the early Universe as today, reshaping our understanding of stellar evolution & gravitational wave origins. www.ozgrav.org/news/binary-...
