Thor’s Hammer Featured as Space Science Images on ESA’s Website
The European Space Agency chose nebula known as 'Thor's Hammer', also known as NGC 2359 for being featured as space science image on its website.
The bright color of the helmet is a field of intense X-ray emissions captured by the super-sensitive cameras aboard ESA's XMM-Newton space observatory. These X-rays emitted by a massive sun at the center of the nebula also known as a Wolf-Rayette star.
Scientists said that Wolf-Rayette stars have at least 20 times the mass of our own sun. Now, Wolf-Rayette star is passing through its final passing and that is why it is releasing a massive amount of material.
The ESA said that the star ejects equivalent of one of our suns every 100,000 years through winds. The disturbance because of the central star helps provide the shades of red and green. All these factors have added to the shape of the nebula.
"The nebula consists of a central bubble surrounded by a tangled web of gaseous filaments, thick channels of dark dust and bright outbursts, where material swept up by the stellar wind has collided with the surrounding gas and triggered rippling shock waves throughout the region", affirmed the ESA.
The image also shows the temperature present in its field. As per the ESA, the blue areas show temperatures ranging from several million up to tens of millions of degrees.
