This week, the first-ever footage of the lethal (to great white sharks) hunting behaviors of Orca pods, SpinLaunch slingshots NASA tech into the sky, and we ask if Kelly Clarkson had a point when she sang “what doesn’t kill you makes you stronger”.


Watch World-First Footage Of Orcas Making A Snack Out Of Great White Sharks

Earlier this year, researchers in South Africa filmed killer whales hunting great white sharks for the first time, and footage of the chase reveals that more orcas are involved than previously thought.

Not only are they visually stunning, but this collaboration has also spotlighted some new astronomical features that haven't been appreciated before. Read the full story here.


Feature of the week: 

Is There Any Truth Behind "What Doesn't Kill You Makes You Stronger"?
