Stargazers will want to check out a special event tonight. Not only will there be a "supermoon," but there will also be a lunar eclipse. It's the first time there has been a supermoon eclipse since 1982.
The "supermoon" happens when the moon is at its closest point to Earth in its orbit. The eclipse is due to start at around 8 this evening and it'll take about an hour for the total eclipse to start after that. If you miss it, there will be another supermoon eclipse in 2033.
