Using Hubble telescope, we've captured images of galaxies with infrared light.

   According to some rules of quantum physics, the forbidden emissions lines should not be there. However, the team says that quantum physics is complicated and some of the rules which underpin their prediction have been made under laboratory conditions on Earth.

It's been known for some time that the Hubble Space Telescope is capable of capturing vivid images of spiral galaxies, and recently it's captured a new galaxy that's been illuminated by the "forbidden" light. It's estimated that the galaxy is about 275 million lightyears from our home planet, and it's called MCG-01-24014.

MCG-24-01014: Galaxy

  The spiral galaxy named MCG-01-24-014 is said to have an extremely energetic core and is known as an active galactic nucleus (AGN): it has been categorised as a Type-2 Seyfert galaxy- and it has been stated that the mission specialists from Hubble, is managed by both European Space Agency and NASA. It is said that the most frequent AGN classes are hosted by Seyfert galaxies, along with quasars.

Although the precise classification of AGNs is complex, Seyfert galaxies tend to be relatively close to each other and their central AGN does not outshine its host. Although quasars are a very distant AGN with extraordinary brightness, far superior to the host galaxies.

The subclasses have also been expanded to include quasars and Seyfert galaxies. Type 1 and type 2 will be the most common subtypes in Seyfert galaxies.By examining their colour spectrum, astronomers have differentiated them from each other and they're the patterns that emerge when light breaks down into individual wavelengths. 

The type 2–3 Seyfert galaxy is emitting wavelength lines which are associated with the specific 'forbidden' emission line.

To find out why the light from the galaxy is considered 'forbidden', because it is necessary to understand the fundamental reasons for the existence of the spectrum. 

And the way they do it is also investigated by Spectra, because some molecules and atoms are absorbing and emitting light at a very specific wavelength.

What's the reason for quantum physics?

The electrons are those particles that orbit the molecules' and atoms' nuclei, which cannot exist in any particular degree of energy. Only very specific quantities of energy will be capable of being gained or lost by electrons during this process. The wavelengths of the light that can be absorbed or radiated are similar to this very special energy.

According to certain quantum physics rules, there should be no prohibited emission lines. The team explains, though, that quantum physics is complex and a number of rules for predicting its existence were developed in laboratory conditions on Earth.

Following these regulations, this emission has been deemed 'forbidden'—which is an occurrence and it is so unlikely that it is typically dismissed. Yet, these assumptions are no longer applied in a vast expanse of space that is surrounded by an extremely powerful galactic core, providing the 'forbidden light' opportunity to be radiated towards us.
