    Dying star: A photo of U Camelopardalis, a star nearing the end of its life located in the constellation of Camelopardalis. #Cosmos

  • Raquel Steele

    Hubble Space Telescope posted this portrait of dying star Camelopardalis (U Cam for short) as it released a spherical shell of gas. U Cam is becoming increasingly unstable, and every few thousand years the red giant's core fuses and it expels stellar material in these eruptions. Although the star itself is small enough to fit into a single pixel of the photo, its brightness makes it appear much larger than it is.

    Star Eruption: Red Giant, Camelopardalis, Caught By Hubble Ejecting Gas (Photo of the last death gasp of a dying star. The ejected gas bubble, which forms the faint outermost shell, is almost perfectly spherical. But U Cam is still a few centuries from puttering out for good, though that's virtually nothing in astronomical terms. Our own sun is still billions of years from turning into a red giant itself, and ejecting material just like this star.)

A dying star. Chi Cygni, shown in this artist's conception, is a red giant star nearing the end of its life. As it runs out of fuel, it pulses in and out, beating like a giant heart and ejecting shells of material. Observations by the Infrared Optical Telescope Array found that, at minimum radius, Chi Cygni shows marked inhomogeneities due to roiling "hotspots" on its surface. (Credit: ESO/L. Calçada)

Camelopardalis, or U Cam, is a star nearing the end of its life. As it begins to run low on fuel, it is becoming unstable. Every few thousand years, it coughs out a nearly spherical shell of gas as a layer of helium around its core begins to fuse. The gas ejected in the star’s latest eruption is clearly visible in this picture as a faint bubble of gas surrounding the star

Images from Hubble Space Telescope. Star cluster Pismis 24 hangs over the dusty clouds of NGC 6357, a nebula about 8000 light-years away in the constellation Scorpius. This picture showed that the brightest star in the cluster is in fact two stars in a tight binary orbit. Each star is about a hundred times the Sun's mass.

"The merging Antennae galaxies. As the two galaxies smash together, billions of stars are born, mostly in groups and clusters of stars."

Solar flare. Beware. Our sun is a very reactive and aggressive kind of sun. This has much more implications on us humans than we originally thought.

LOVE the Hubble! - The unbelievable beauty and valuable knowledge it brings us. (Stars in Scorpius, from the Hubble Telescope)

Star on a #Hubble diet. The star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 that extends one degree on the sky in the direction of the Scorpius constellation. Part of the nebula is ionised by the youngest (bluest) heavy stars in Pismis 24. The intense ultraviolet radiation from the blazing stars heats the gas surrounding the cluster and creates a bubble in NGC 6357. The presence of these surrounding gas clouds makes probing into the region even harder.
