What does a star look like from Earth if it goes supernova?

Last night I looked out my window, and saw what looked like a big star in the western sky. It was flickering, like a star, but something like 20 times the size of a normal star. It definitely was not a plane or helicopter, because it wasn't moving. I watched it for about a minute, then looked away, and when I looked back, it was gone. What could it have been?What does a star look like from Earth if it goes supernova?What you saw was the planet Venus.

It was the planet Venus. It's been in the western sky for months now, and will be there for a couple more months. It disappeared because it went behind a distant cloud, too far away to be visible from your location. The last naked eye supernova was in 1987. It looked just like a very bright star. If there were a new supernova, it would be all over the news and the internet.What does a star look like from Earth if it goes supernova?Supernovas are quite common. If you have a huge telescope, you can find dozens every night. But naked-eye supernovas happen only a few times in a millennium. I you ever see a supernova without a telescope, it will be front-page news, and not just in astronomy journals.What does a star look like from Earth if it goes supernova?
What you saw was Venus. Strangely enough, that appearance is probably a good indication of what a supernova might look like, if one were near enough. If/when Betelgeuse goes supernova, it might bear a pretty close resemblance to how Venus has looked for the past couple months.What does a star look like from Earth if it goes supernova?You saw the planet Venus. A supernova looks like a new star in the sky, sometimes being bright enough to see in daylight, and is visible in the sky for many days... If there was a supernova that bright, it would be all over the news.
