The Moon's presence in the sky is a comforting and familiar one.
Earth's only permanent natural satellite, it normally appears to 'shine' bright white after darkness falls, an effect caused by reflected sunlight.
But anyone gazing up to the heavens in the UK right now would be forgiven for doing a double take - for rather than its usual pale milky hue, the Moon has taken on a distinctive shade of orange.
Its appearance has sparked discussion on social media among people startled by what they've seen.
"Even the moon looks a bit warm this evening," said Kate Collins on Twitter, referencing the extreme heat Britain has been experiencing recently.
Space Pete tweeted: "UK peeps, there's a stunning red moon visible in the south-east right now, low in the sky. Go look!"
And UK Weather Geek said: "Stunning moon tonight."
NASA's Solar System Exploration website explained in May why the Moon can sometimes look different when it is low in the sky.
"It tends to have a more yellow or orange hue, compared to when it's high overhead," said NASA.
"This happens because the Moon's light travels a longer distance through the atmosphere. As it travels a longer path, more of the shorter, bluer wavelengths of light are scattered away, leaving more of the longer, redder wavelengths. (Dust or pollution can also deepen the reddish colour.)"

In Britain, a new full Moon is approaching, when the celestial body will appear at its biggest. The next one will be on July 24 at 3.36am - this month's is often known as the 'Buck Moon' or 'Thunder Moon'.
NASA said in 2011: "According to many Native American traditions, July is normally the month when the new antlers of buck deer emerge from their foreheads in coatings of velvety fur — hence one of the names for the full moon.
"The full moon in July also is called the Thunder Moon because of the frequency of thunderstorms during this hot, dry month."
