On Monday, a super blue moon lit up the night sky, giving people a glimpse at this rare spectacle. August's full moon also goes under different monikers : supermoon, blue moon and Sturgeon Moon.
Though we had a super blue moon somewhat recently, in August 2023, NASA predicts the next super blue moons will occur in January and March 2037. All the more reason to make sure you don’t miss ...

In a technique known as blue field entoptoscopy, the effect is used to estimate the blood flow in the retinal capillaries.The patient is alternatingly shown blue light and a computer generated picture of moving dots; by adjusting the speed and density of these dots, the patient tries to match the computer generated picture to the perceived entoptic dots.
Some of the brightest stars in the night sky, such as Rigel and Antares, are in the list. While supergiants are typically defined as stars with luminosity classes Ia, Iab or Ib, other definitions exist, such as those based on stellar evolution. [1] Therefore, stars with other luminosity classes can sometimes be considered supergiants.
Rigel and the IC 2118 nebula which it illuminates.. It was once believed that blue supergiants originated from a "feeding" with the interstellar medium when stars passed through interstellar dust clouds, [11] [8] although the current consensus is that blue supergiants are evolved high-mass stars, a natural consequence of stellar evolution, larger and more luminous than main-sequence stars.
A full moon shines in the night sky in Surprise, Ariz., on Aug. 1, 2023. ... The time between super blue moons can be as much as 20 years – but in general, 10 years is the average.
The blue sky spectrum contains light at all visible wavelengths with a broad maximum around 450–485 nm, the wavelengths of the color blue. Diffuse sky radiation is solar radiation reaching the Earth's surface after having been scattered from the direct solar beam by molecules or particulates in the atmosphere.
