This visible light image shows the T Tauri system along with the nearby Nebula NGC 1555. Discovery in 1852, it is now known that it is a young triple star system with a dusty disc of material surrounding the binary component, t tauri south, which is too widespread to be observable with visible light.

It is the latest cosmic “cover -up” game, since attenuation occurs when a circular disc of a nearby star passes in front of T Tauri N.
The story of how the Sun itself was born is still a cosmic mystery.
This look at the stars found in the densest region of the Orion Nebula, near the heart of the Trapecio group, shows a modern vision within a region of the stars of the Milky Way. However, stars formation properties vary during cosmic time, from galaxy to galaxy, on different radios of the galactic center, etc. All these properties and more must be taken into account to compare the sun with the general population of stars within the universe. Keep in mind that our sun, born 4.6 billion years ago, is less than 85% of the stars. (Credit: X -rays: NASA/CXC/PENN STATE/E.FEIGELSON AND K.GETMAN et al.; Optic: NASA/ESA/STSCI/M. Robberto et al.)
Formed 4,600 million years in the past, we can only see what is currently surviving.
Although we now believe that we understand how the sun formed and our solar system, this early view of our past and protoplanetary stage is only an illustration. While many protoplanets existed in the early stages of the formation of our system a long time ago, today, only eight planets survive. Most of them have moons, and there are also small rocky, metallic and ice cream bodies distributed in various belts and clouds in the solar system.. (Credit: Jhuapl/Swri)
But in other parts of the galaxy, sun -shaped stars are formed continuously.
This animation changes between an optical view of the dark molecular cloud that houses protosar L1527 (red circle) and infrared data of the wise mission that shows the protoplanetary system and its exits directly. Many Prostastars are analogs of stars similar to the sun, except that they show us how our sun could have been 4.6 billion years ago: when it was being formed for the first time.

This expansive view of the T Tauri system and its surroundings reveals itself with a brilliant bright nebula: NGC 1555. Although other bright stars abound, they are not visible here are the two trinarians of T Tauri (north): and b. These two stars have a dusty album around them, which may have begun to go in front of T Tauri North only in recent years. (Credit: Ta Rector/University of Alaska Anchorage, H.

Its brightness not only varies over time, but a nearby nebula also shows variability.
