A ghost face with glowing eyes appeared in the deep space in a brand new image coming from the Hubble Space Telescope.
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. 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. The study's researchers have given it the nickname "Jack-o'-lantern Nebula", apropos for Halloween. "Green and red represent light emitted primarily by dust radiating at different temperatures, though some stars radiate prominently in these wavelengths as well", the JPL statement said.
In a higher-contrast image, however, the orange and green create an orange tone flawless for Halloween. The blue colour represents a wavelength mostly emitted by stars and some very hot regions of the nebula, while white coloured regions indicate where the objects are bright in all three colours.
In this week's Halloween-themed image advisory, the Space Telescope Science Institute says only a few hundred such ring galaxies reside in our cosmic neighborhood.
According to the observations of the researchers, this particular region is located on the edge of our galaxy, the Milky Way.More news: Nationals beat Astros to win maiden World Series title

A high-contrast version of the same image makes the red wavelength more pronounced. When the tallies of young stars are put together with tallies of adult stars in these regions, the data will enable scientists to determine if the rates of planet and star formation in the galaxy's outer regions differ from those in middle and inner regions.
By dissecting these itemized Hubble perceptions, cosmologists could then pick which frameworks are practical objectives for catch up with NASA's James Webb Space Telescope, planned to dispatch in 2021.
'Each "eye" is the bright core of a galaxy, one of which slammed into another. But in this case, the galaxies are roughly the same size, producing this unique "ring" structure that lasts for about 100 million years.
The objective is to order a strong example of close by interfacing cosmic systems, which could offer knowledge into how universes developed after some time through galactic mergers.
