ESO’s Very Large Telescope captures rare 'space butterfly'; Pic inside

An image of a space gas bubble taken by European Sourn Observatory’s (ESO) Very Large Telescope that resembles butterfly has intrigued internet. Shared by European Sourn Observatory on Twitter, image depicts a bubble known as NGC 2899 located between 3000 and 6500 light-years away in Sourn constellation of Vela ( Sails ) that looks like a butterfly with its symmetrical structure, beautiful colours, and intricate patterns.  

Astronomers were able to capture highly detailed image of NGC 2899 using FORS instrument installed on UT1 (Antu), one of four 8.2-meter telescopes that make up ESO’s VLT in Chile. image was taken as a part of ESO Cosmic Gems program, an initiative to capture unique space phenomenon and visually attractive celestial objects using ESO telescopes for research purposes. vibrant butterfly bubble seems to extend two light-years from its center and glows sharply among stars of Milky Way galaxy. Furr, its temperature can reach up to ten thousand degrees.

According to a report by Stephen  Memorial Observatory, Hiram College, Ohio, high temperature in bubble are due to “large amount of riation from nebula’s parent star, which causes hydrogen gas in nebula to glow in a reddish halo around oxygen gas, in blue.” object has two central stars, which are responsible for its symmetric appearance.  structure has stunned astronomers as only 10–20 percent of planetary nebulae display this of bipolar shape as Butterfly bubble.  

ESO’s high-resolution instrument

While ESO’s high-resolution instrument was one of first to be installed on ESO’s VLT and is behind numerous beautiful images, this particular image has been recorded using Focal Reducer and low dispersion Spectrograph by scientists. “FORS has contributed to observations of light from a gravitational wave source, has researched first known interstellar asteroid, and has been used to study in-depth physics behind formation of complex planetary nebulae,” ESO revealed in its blog post.
