In terms of luminosity, the amount of energy it pumps out is relative to the amount of energy the Sun gives out. The star's temperature reaches about 7,414 Kelvin, which is hotter compared to the Sun with only 5,777 Kelvin.
Smaller stars are more energy efficient as they use lesser energy and therefore tend to live longer. For example, a red star could either be large or small. Although its size does not have any relationship with its color. V372 Orionis's color and type is a blue subgiant star based on its spectral class (B9 III/IV). V 372 Orionis is about 6.41 times bigger than the Sun in radius. Moreover, it does not have any known exoplanets orbiting it perhaps due to their size, which may be challenging to spot compared to smaller stars that can easily be detected. That also means it is within the Milky Way galaxy but not within the Solar System since there is only one star in it, which is the Sun. Nonetheless, it is within its boundaries.

On the other hand, the diffraction spikes of the NASA/ESA/CSA James Webb Space Telescope (JWST) are six-pointed due to Webb's hexagonal mirror segments and three-legged secondary mirror support system. These visible artifacts are caused by starlight interacting with Hubble's inner workings, and they provide indications of Hubble's structure as a result.įour vanes within Hubble support the telescope's secondary mirror, which creates the four spikes encircling the stars in this view. The diffraction spikes encircling the brilliant stars are Hubble's faint imprint on the celestial photograph of the stars. Orion Variables are frequently connected with diffuse nebulae, and V 372 Orionis is no exception the Orion Nebula's patchy gas and dust saturate the image. Both stars are located in the Orion Nebula, a massive star formation zone 1,450 light-years from Earth.Īstronomers can see irregular brightness from these newborn stars as they go through some turbulent mood swings and growing pains. SciTech Daily reports that the brilliant V 372 Orionis, a particular type of variable star called Orion Variable, is featured at the center of the image along with a tiny companion star in the upper left corner. Both are located in the Orion Nebula, a massive area of star formation located 1450 light years away from Earth. This Hubble Space Telescope image features the bright variable star V 372 Orionis and its smaller companion in the upper left. FAQ – Frequently Asked Questions.(Photo : ESA/Hubble & NASA, J. License: Creative Commons Attribution-Share Alike 3.0 Unported License: Creative Commons Attribution-Share Alike 4.0 International If you look closely, you can see that the lines emanating from the stars in the four directions are not of uniform intensity but show intensity oscillations typical of diffraction. Darker, more spread-out objects like nebulae or galaxies do not show visible levels of this distortion. It is only noticeable for bright objects where a lot of light is concentrated on one spot, such as stars. The crosses, known as diffraction spikes, are caused by the light’s path being disturbed slightly as it passes by the cross-shaped struts that support the telescope’s secondary mirror. The cross shape visible on bright objects (such as stars) in Hubble images is a form of distortion that is visible in all telescopes that use a mirror rather than a lens to focus light rays. This is what happens with the Hubble images as well : Diffraction spikes produced by various support arrangements for the secondary mirror.
