Aussies were treated to a dazzling pre-dawn show as the Eta Aquariid meteor shower lit up the sky. The spectacle is set to continue all week.

Ozzie. Stargazers have been treated to a cosmic spectacle this morning, with the Eta Aquerd meteor shower lighting up our pre dawn skies. This dazzling display will continue through the week, with experts predicting it to be one of the most impressive meteor showers in the Southern hemisphere. For more, who else but astrophysicist doctor Brad Taka, Good morning. What's the cause of this meteor shower?
Yeah, so this is a great one because this is bits of Hayley's comet that the Earth is passing through. So as Hailey's comet, that famous one that we see every seventy six or so years, as it goes around the Sun, it leaves this trail of debris. It's like a boat leaving a wake through the water. And as the Earth goes around our orbit around the Sun, we intersect it and we hit those little tiny bits of rock and ice and they burn up in our skies. As he said, happening this week.
So bitts break off, do they?
Yeah, it's kind of like so as the comet heats up, a little bit of what we called sublimates it, it turns to gas and so that gas comes off and leaves little bits of rock and ice in this trail. It's like crumbs being left around the solar system when we hit these trums crumbs. But because we're traveling at hundreds of thousands of kilometers an hour, when this intersection happens between the two, they burn up really bright quickly in our sky.
Okay, so where can we say the sublimation?
Yeah, I like it. So you want to look in the northern sky in the early morning hours, so all across Australia. So this is a great thing everywhere in Australia. You can see it from about two thirty three am to five am looking towards the north. Now, they enter from the star near the star at Aquariad, which is why we call them at equeriods. But they can burn up any kind of spot from there, so you really just want a nice clear view to the north, giving your eyes a few minutes ten minutes or so to adjust the darkness, and being patient because while there'll be a good rate of meteors, you know, you may see a few and then wait for a while. So it's a patient waiting game, but hopefully worth the reward in those early morning skies.
Okay, this is perfect for the sunrise crew. Finally something for us from two thirty to five am seeing Bran
