- This phenomenon occurs when smoke particles scatter light, emphasizing red wavelengths.
Significance of Supermoons
- Supermoons occur 3-4 times a year, with this being the first of four consecutive supermoons in 2024.
- The next supermoons in September and October are expected to be nearly as close to Earth, making them significant for skywatchers.
Cultural Impact
- The Blue Moon is often associated with folklore and the phrase 'once in a blue moon,' highlighting its rarity.
- Stargazers are encouraged to observe the moon during this period, as it offers a unique opportunity for photography and appreciation of lunar phenomena.
What the papers say
According to Kelly Tyko from Axios, the Blue Moon will not actually appear blue but will be notably larger and brighter due to its supermoon status. Tyko emphasizes that this moon is part of a series of supermoons this year, with the next two expected to be similarly impressive. Meanwhile, Simon King from BBC News notes that atmospheric conditions, particularly smoke from North American wildfires, may give the moon a reddish tint, enhancing its visibility across the UK. This interplay between natural phenomena and atmospheric conditions illustrates the complexity of lunar observations. Marcia Dunn from The Independent adds that this supermoon is a chance for stargazers to engage with the night sky, as it coincides with a series of lunar events throughout the year, making it a significant moment for astronomy enthusiasts.
