•• V838 Monocerotis Revisited • Here we see a light echo. A view of an expanding halo of light around a distant star, named V838 Monocerotis (V838 Mon). The illumination of interstellar dust comes from the red supergiant star at the middle of the image, which gave off a flashbulb-like pulse of light.

• Light Echoes Around RS Puppis Cepheid variable star puts on a spectacular light show 8.3.24 • In 2010 the variable star RS Puppis was observed over a period of five weeks, showing the star growing brighter and dimmer as it pulsates. These pulsations have created a stunning example of a phenomenon known as a light echo, where light appears to reverberate through the murky environment around the star. For most of its life, a star is pretty stable, slowly consuming the fuel at its core to keep it

This isn't an expanding star: this is a light echo! Seen in this time-lapse sonification, a pulse of light from the star V838 Monocerotis gives the illusion that the surrounding dust is expanding into space. In reality, the dust shells aren't expanding at all – the light from the star's flash is just reaching dust that is farther away. Hubble captured the first image #OTD in 2002! This star is located about 20,000 light-years away, at the outer edge of our Milky Way Galaxy. In this sonification,

Shine bright like an interstellar light echo ✨🤩 A shell of light from an exploding star illuminates the darkness of space, putting on a stunning light show. In an effect known as a light echo, the initial light emitted from supernova SN 2014J, which was observed in 2014, can be seen pulsating off of nearby dust clouds in the galaxy M82.

In 2002, an obscure star named V838 Monocerotis suddenly did something incredible. It erupted, transforming from a dim, unnoticed star into the brightest object in the entire Milky Way galaxy. For a brief moment, it was 600,000 times brighter than our Sun. It is stationary dust that was already surrounding the star. When the star flashed, that pulse of light traveled outward, illuminating the dust layers one by one. We are watching the light travel through the dust, not the dust moving through s
