Nebula Because of its weight and luminosity it becomes a Red Super Giant. d) Barnard's Star. The stars estimated age is 724 million years. The Eskimo Nebula (NGC 2392) is a somewhat brighter planetary nebula known for its peculiar shape, which has also earned it the nickname the Clown Face Nebula. "It suggests that planet-formation around stars much more massive than the sun may [be] common," read an Astronomy and Astrophysics paper concerning the discovery. Though Pollux is brighter than Castor, it is Castor who is designated the Alpha Geminorum. The team concluded that these variations might be due either to non-radial pulsations, to a surface feature combined with rotation, or to the presence of a substellar companion with a mass 3 to 12 times that of Jupiter. Like other red giants, this process causes Pollux to become cooler than our Sun hence its orange color and much larger: 10 times the diameter of the Sun. However, it is unknown if it will become a red supergiant, like it was thought to have been, and then possibly explode into a grand supernova. Constellation Puppis second brightest star is only 1,100 light-years from Earth. It would affect lots of ocean life as well, but a lot would survive. It has exhausted the hydrogen in its core to become a white supergiant and no longer fuses hydrogen. Will Pollux become a supernova? Now, that would be a true sight. Betelgeuse is due to go supernova. Pollux is believed to have started its life as a main sequence star of the spectral type A, but eventually spent its supply of hydrogen and evolved into an orange giant. Gemini constellation map by IAU and Sky&Telescope magazine. A star named Sirius appears as the brightest star in the nighttime sky, even though a star named Pollux actually gives off more light. The name was later translated into Latin as Posterior Brachii, meaning the end in the paw. In Arabic astronomy, Castor and Pollux constituted one of the front paws of an enormous lion, which stretched across a third of the sky.

And as a reminder, the sun is about 8.3 light- minutes from Earth. -0.05) because it is intrinsically more luminous than Pollux, with an absolute magnitude of -0.30. In other words, the star is in the late evolutionary stages of its life. But the Earth will become uninhabitable much sooner than that. It is about 170 times more luminous than the Sun, while Pollux shines with 43 solar luminosities. Around the same distance as the red giant Arcturus, the brightest star in the constellation of Botes. To that direction, recent supernova spectra are examined and historical supernova Ia . Delly Cartwright is a teenage girl from District 12 who grew up being friends with Peeta Mellark. earth. A blue-white supergiant, Deneb rivals Rigel as the most luminous first-magnitude star. A star that is at least five times bigger than our Sun can become a supernova. 1.93), Alhena (Gamma Gem, mag. The term 'supernova' comes from the Latin for new ( nova) and above ( super ), as supernova appear to be new stars in the night sky. 28. Stars in the mass range of Deneb eventually expand to become the most luminous red supergiants, and within a few million years their cores will collapse producing a supernova explosion. The best time of year to observe the stars and deep sky objects in Gemini is during the month of February, when the constellation is prominent in the evening sky. Their estimated age is about 400 million years. Once an A-type main sequence star, Pollux has exhausted the hydrogen at its core and evolved into a giant star with a stellar classification of K0 III. It will keep getting bigger until it reaches the end of its life cycle. Along with Castor, Pollux is one of the two main guideposts for the asterism, which is sometimes nicknamed "the twins.".
