There are millions of asteroids in the Solar System and relatively few astronomers to track them. They’d hate to miss that one dangerous rogue headed on a collision course with Earth.

So NASA has made it easier for the amateur stargazer to record and compare their discoveries and put extra eyes on the asteroid belt between Mars and Jupiter.

NASA and Planetary Resources Inc. have developed a computer program that is based on an algorithm that analyzes images for potential asteroids. The new asteroid hunting application, available for free download here, was announced Sunday by NASA at the South by Southwest Festival in Austin, Texas.

LAS VEGAS — Your iPhone captures great imagery, but sometimes the built-in zoom just isn’t enough. An ingenious gadget that quickly connects smartphones to almost any optical device gives your everyday camera superpowers.

Cult_of_Mac_CES_2015 The Carson Universal is an incredibly simple idea, but it delivers some pretty astonishing results. You can use it to connect your smartphone to telescopes, binoculars, microscopes, spotting scopes or almost any other optical device with a rounded eyepiece. Instead of buying a specialized, device-specific adapter, it’s a one-size-fits-all optical attachment.

“It kind of opens up the possibilities,” said Michelle Hyers, the engineer who designed the Carson Universal.

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.

Some space geeks are calling today “The Day the Earth Smiled,” because the Cassini probe is set to take a picture of our planet as seen from Saturn later this afternoon. To honor this momentous occasion, the maker of astronomy software SkySafari is giving away basic versions for iOS and OS X (and discounting the Android version) through Sunday.

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

venus-transit-120601

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.
