Have you ever heard of a star that’s so bright it could light up an entire galaxy? Well, that’s RS Puppis for you! This shining star is located about 8,000 light-years away from Earth, and it’s so bright it could light up an entire Milky Way-sized galaxy. Talk about star power!
But it’s not just RS Puppis’ brightness that makes it special – it’s also got some serious style. This star is what’s known as a “pulsating supergiant,” which means it expands and contracts like a beating heart. How cool is that?
But here’s the really wild part – RS Puppis is so massive it’s actually losing weight! That’s right; this giant star is shedding mass at an incredible rate, losing about 10 million times the mass of the Earth every year. Talk about a dramatic weight loss!
A star of staggering proportions
RS Puppis is a massive star that is classified as a supergiant. It is one of the largest known stars in the universe, with a size that is estimated to be hundreds of times larger than the Sun.
To put its size into perspective, if RS Puppis were placed at the center of our solar system, its surface would extend beyond the orbit of Jupiter, the largest planet in our solar system. This means that RS Puppis is significantly larger than the Sun and most other stars in the universe.
NASA seems to celebrate the Holidays in its own cosmic way, as it has just released a sample of sonifications generated by the RS Puppis star:
#HappyHolidays from Hubble!
Here’s a festive sonification of RS Puppis, a glittering star wreathed with dust.

It is possible for stars to generate sound waves under certain conditions. This can occur when a star experiences rapid changes in its surface temperature or when it undergoes violent changes, such as a supernova explosion.
For example, when a star explodes as a supernova, it can produce shock waves that travel through the surrounding gas and dust. These shock waves can produce sound waves that propagate through the interstellar medium and can be detected by telescopes and other instruments.
This celestial wonder known as RS Puppis is located in the southern hemisphere and is part of the larger constellation of Vela.
Puppis, the name of the constellation where the giant star is located, got its name after the Latin word for “stern,” as it is located near the stern of the celestial ship Argo Navis. That’s right – this constellation is basically the cosmic equivalent of the back of a ship!
But don’t let Puppis’ nautical origins fool you – this constellation is full of stars that are out of this world.
Puppis, a modern constellation
Puppis is one of the 88 modern constellations recognized by the International Astronomical Union (IAU), and it occupies an area of about 673 square degrees on the celestial sphere.
Other important stars from the Puppis constellation, except for RS Puppis, are V Puppis and HD 64760. The former is a bright, blue-white main-sequence star that is located about 800 light-years away from Earth. It is a relatively young star that is still in the process of burning hydrogen in its core, and it is thought to be similar to the Sun in many ways.
RS Puppis is a star that has been known to astronomers for many centuries. It was first recorded by the ancient Greek astronomer Ptolemy in the 2nd century CE, and it has been observed and studied by astronomers for many centuries since then.
The star is named after the constellation in which it is located, Puppis, which is part of the larger constellation of Vela. The name “RS Puppis” is derived from the star’s position in the constellation and its brightness. The “RS” stands for “Ruyer-Serrano,” which is the name of the astronomers who first cataloged the star in the early 20th century.
