The US space agency sparked a full-blown Halloween mood among social media users this Wednesday, by posting a magnificent image of a gas and dust cloud surrounding a massive star taken by NASA's Spitzer Space Telescope, which curiously resembles a cosmic pumpkin.
Scientists, who nicknamed the extraordinary structure the “Jack-o’-lantern Nebula”, believe that the massive O-type star in the centre is likely to be responsible for the creation of the pattern. While an outflow of radiation and particles from the star sweeps the surrounding dust and gas out, it helps to create the peculiar hollows that resemble a carved face.
At the same time, the colours in the image can be explained by the combination of three wavelengths of infrared light, with green and red colours representing light released by dust radiating at different temperatures. The central O-type star, which is believed to be about 20 times heavier than the Sun, is seen as a white spot in the centre.
NASA said that the data used for the creation of image was collected during the previous Spitzer “cold mission”, that ran between 2004 and 2009.
Previously the space agency posted a scary-looking picture of the Sun that also vividly resembled a jack-o’-lantern, a symbol of the Halloween season on their Facebook page, that image was taken by NASA’s Solar Dynamics Observatory back in 2014.
