Pana Hema-Taylor, of Ardgowan School, asks :-

Is it possible to see stars in daytime?

Vicki Hyde, author of the book Godzone Skies - Astronomy for New Zealanders, responded.

Yes, but you would need a telescope with a good tracking mechanism.

This question comes up so often that it's answered in the online Astronomy FAQ (Frequently Asked Questions: http://sciastro.astronomy.net/sci.astro.html).

The ancient Greeks thought that stars were visible to the naked eye, but their most impressive daytime observation was seeing the occasional sunspot.

Sometimes it is said you can see stars in the daytime if you look up a tall chimney or mineshaft. That's been tried but, as far as I know, has been unsuccessful, despite one group resorting to binoculars and knowing they had a couple of bright stars in the right position. Part of the problem is that having such a restricted viewing area means you would be lucky to see any stars, even at night! (Try looking through a postal tube at the night sky and you'll see what I mean.)

But the main reason for the lack of stars is the bright daylight. Astronauts say that when they're in space, it's the Earth's light, not the Sun's, which drowns out all except the very brightest stars. Those Star Wars images of star-filled skies above glowing planets are not something you'd actually see, sadly.

You could see a planet in the daytime, but you'd have to know where to look. I once spotted Venus in the early afternoon, shining overhead. The only reason I could see it was that it was very bright and happened to be relatively close to Earth at the time. I was so startled, I wondered briefly if it was a UFO!
