If you got one of those amazing new iMacs with the crazy 5K pixel resolution, you’d be crazy not to watch this stunning animation of the sun by YouTuber James Tyrwhitt-Drake. You can gaze at the star at the heart of our solar system for a full eight minutes, using YouTube’s new 4K resolution setting and that killer new Mac.

This timelapse covers about 16 days of solar activity, focusing on the largest sunspot in the last 22 years (about two solar cycles), which is cleverly named AR 2192.

Check it out and enjoy.

Watch The Transit Of Venus Across The Sun Today With The Help Of Your iPhone

Watch The Transit Of Venus Across The Sun Today With The Help Of Your iPhone

You might have heard that today’s a pretty special day, astronomically speaking. Venus is in transit between Earth and the Sun today, which is a once-in-a-lifetime event. Today only, right before sunset in the United States, if you look up at the sun, you’ll be able to see the silhouetted Venus passing between us and our life-giving star. And due to the differences between Venus’s solar year and our own orbit around the Sun, you’ll have to wait a hundred years until this event happens again.

In other words, if you’re American, you don’t want to miss this if you have any curiosity about the heavens at all. And luckily, there’s an app that will help you make sure you don’t.

Brian Cox’s Wonders of the Universe iPad App Is Just Heavenly [Review]

Celebrity physicist Brian Cox is famous in the U.K. for making physics accessible to the public through bestselling books and several popular TV series. Now he brings elements of both to a gorgeous new iPad app: Brian Cox’s Wonders of the Universe ($6.99).

Featuring amazing animations and lush, high-production video, the app will sweep you back in time to witness the Big Bang, and then look ahead to the universe’s end, when the last black dwarfs will fizzle away to entropy.

As Prof. Cox points out: while the universe evolves momentarily from order to chaos, now is a precious window of time when life is briefly possible, for us to be able to contemplate the universe…

Forget The Death Star, Apple Has Destroyed Another Galaxy In Mountain Lion [Image]

This image of the NGC 3190 Galaxy is the one Apple altered for Mountain Lion.

Back when OS X Lion first came out, amateur and pro astronomers alike noted with bemusement that Apple had used their new operating system as an excuse to alter the Universe according to their whim. Most notably, when picking a picture of the Andromeda Galaxy as OS X Lion’s default wallpaper, Apple photoshopped several stars and an entire separate galaxy out of the picture.

When Apple debuted the next version of OS X, Mountain Lion, with a brand new galactic image as the default wallpaper, we wondered if Apple had done it again. As it turns out, they have.
