There will be a sight in the sky tonight that has been seen in centuries.

There’s a full moon, and a partial blood moon eclipse – the longest in almost 600 years.

Senior physics lecturer at RMIT and member of the Space Industry Association of Australia, Dr Gail Isles, says it’ll be a “micro moon”.

“The moon is far, far away from us,” she told Neil Mitchell.

The eclipse will actually begin before the moon rises above the horizon in Melbourne, but because of its unusually long duration, there will still be plenty of time to catch a glimpse.

“From about 8pm onwards you should be able to see that partial eclipse,” she said.

The eclipse should be visible until 11.03pm, and will be best viewed from locations with a clear view of the sky to the east and north-east.
