The legendary Hubble Telescope captured a stunning image of the energetic spiral galaxy NGC 5728 130 million light-years from Earth.
Open Field Camera 3 (WFC3) Hubble, installed by astronauts on the latest Hubble Maintenance mission, has captured this intense light in the visible and infrared spectrum.
Truth has much more radiation at wavelengths that even Hubble cannot see.
In this image, NCG 5728 looks like a spiral galaxy of beautiful, bright rods. But what is not seen in this image is that NCG 5728 is a very energetic galaxy known as the "Seyfert Galaxy." Are a subset of the highly energetic class of galaxies known as active galactic nuclei (AGNs). The energy released from them is equal to the total energy of the rest of the galaxy and is one of the most powerful sources of energy in the universe. It is clearly visible. The radiation from other AGNs, such as quasars, is so intense that it is almost impossible to see their host galaxy.
To observe the universe more closely, we must wait for the next generation of space telescopes. The launch of the James Webb Space Telescope is currently scheduled for December 18. This powerful scientific tool will look at some of the oldest galaxies in our universe with larger and sharper mirrors than Hubble, and will make it possible to see planets formed in distant star systems.
