Hack is bringing you stories from people affected by the war in Gaza, as the conflict escalates in the Middle East a year on from the October 7 attacks.

Yesterday marked a year since the attack by Hamas in southern Israel, while today marks a year since Israel's invasion of Gaza started. 

Today Perth doctor Mohammed Mustafa tells us why he risked his life to volunteer in Gaza, the horrors he saw, and how hard it's been to adjust to life now he's home. 

Plus, young people in Warrnambool are fighting to stop seismic testing offshore. 

And a spacecraft is on its way to find and study the asteroid NASA rammed in its save-the-world test.

Guests:

• Mohammed Mustafa, emergency physician
• Dr Laura Driessen, radio astronomer, University of Sydney
