Hubble Spots Galaxy with Enigmatic 'Forbidden' Light

The Hubble telescope has identified a distant bright spiral galaxy named MCG-01-24-014, located 275 million light-years away from Earth.

MCG-01-24-014 possesses an energetic core known as an active galactic nucleus (AGN), categorizing it as a Type-2 Seyfert galaxy. Seyfert galaxies, like quasars, host common subclasses of AGNs.

Seyfert galaxies and quasars, two prevalent types of AGNs, have subclasses. In the case of Seyfert galaxies, the main subcategories are Type-1 and Type-2, distinguished by their spectral patterns.

'Forbidden' emission lines in Type-2 Seyfert galaxies challenge certain rules of quantum physics.

Spectra, formed by the absorption and emission of light at specific wavelengths, are governed by quantum physics principles.

Quantum physics rules governing 'forbidden' emission lines were formulated under laboratory conditions on Earth.

However, in the unique conditions of space and within the energetic core of a galaxy, these assumptions no longer apply, allowing the 'forbidden' light to be observed.

The observation of 'forbidden' light challenges traditional understanding and offers unique insights into the complex and dynamic processes occurring within the core of Seyfert galaxies, expanding our knowledge of astrophysics.
