Lots of stars have material around them, wither left over from their formation, or expelled as they die. And you'll never see this message again. AURA’s Space Telescope Science Institute in Baltimore, Maryland, conducts Hubble science operations. What it found was not a nova, but one of the oddest stars in the galaxy. The rotation of the image on the sky with respect to the north pole of the celestial sphere. You can cancel anytime. The circular feature has now expanded to slightly larger than the angular size of Jupiter on the sky. During its outburst the star brightened to more than 600,000 times our Sun's luminosity. Red supergiants are known to undergo periodic paroxysms, for example, but such things are generally not this powerful. Milky Way : Star : Evolutionary Stage : Red Supergiant. You’ve run out of free articles. Each individual image is 82 arcseconds (7.8 light-years or 2.4 parsecs) wide. The date and time the release content became public. V838 Monocerotis is "the prototype of a new class of star," assert Israeli astrophysicist Alon Retter and his colleagues in a recent review article. V838 Monocerotis (V838 Mon) is a red variable star in the constellation Monoceros about 20,000 light years (6 kpc) [1] from the Sun, and possibly one of the largest known stars.The previously unknown star was observed in early 2002 experiencing a major outburst. We could have 25 Hubbles up there for 25 times 25 years and still only have scratched the surface of what’s out there to see. 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 two years ago. The date(s) that the telescope made its observations and the total exposure time. Right ascension – analogous to longitude – is one component of an object's position. A name or catalog number that astronomers use to identify an astronomical object. Although this image of the heavens came only from the artist's restless imagination, a new picture from the NASA/ESA Hubble Space Telescope bears remarkable similarities to the van Gogh work, complete with never-before-seen spirals of dust swirling across trillions of kilometres of interstellar space. The camera filters that were used in the science observations. The distance from the sun is estimated 20,000 light years away. This sequence of pictures from May to December 2002 shows apparent changes in the appearance of the circumstellar dust as different parts are illuminated sequentially. The red star at the center of the eyeball-like feature is an unusual erupting supergiant called V838 Monocerotis, located about 20,000 light-years away in the winter constellation Monoceros (the Unicorn). The mass is estimated 15 solar mass and solar luminosity is 6 × 104. From the first to last image the apparent diameter of the nebula appears to balloon from 4 to 7 light-years. Over just a few years the structure wouldn’t be seen to expand at all; we’re just seeing different structures (or different parts of the same structure, like filaments or compressed regions) as the flash of light moved through the nebula.*.
