iPhone makes quick astronomy

I’ve always wanted to get into astronomy since the late 1990s but could not make it due to busy schedules (yeah lame excuse, I know), lack of mentor, not having a clue how to find and identify objects in the sky, etc.

Then, last night I stumbled upon an iPhone app, SkyView which uses Augmented Reality (AR) to reveal the current positions of planets, stars, constellation, satellites and even the International Space Station (ISS)!

I demonstrated the wonder of the app to my kids outside our home just now. Although the sky was cloudy, we could still see the moon so I used the moon as the reference. SkyView accurately revealed the exact position of the moon on my iPhone screen. Tonight, we found a lot of constellations, including Virgo which was behind the moon. Next to the moon was Saturn, as illustrated in Figure 1.

Not too far away from our moon, we found three satellites, the COSMOS 1536 (below the moon), COSMOS 1975 (slightly above the horizon but behind the apartment and MIDORI II (ADEOS-II) (further to the right of the moon). See their illustration in Figure 2, 3 and 4 respectively.

Beside these, we also found the Hubble space telescope and the ISS (International Space Station). Both of them were below the horizon and behind (or under?) our house!

The SkyView app is a great iPhone app for astronomy hobbyists and perfect education tool for both parents and kids. It’s certainly worth investing. It costs only $1 and there is also a stripped down version which is free.
