Astronomers find two brown dwarfs with an unusual composition

The new substellar objects are brown or brown dwarfs that have many similarities with stars.

However, these gaseous bodies do not have enough mass to initiate nuclear fusion, so they are more like small planets than stars.

Moreover, the pair are the most similar to planetsbrown dwarfs that can be observed in the oldest population of stars in the Milky Way, NASA officials said in a statement. They can help researchers learn more about planets outside the solar system. Researchers studied them using data from NASA missions. The objects were named WISE 1810 and WISE 0414.

When scientists studied them, they were surprisedseeing that these two brown dwarfs have very little iron compared to what is typically observed in brown dwarfs. This suggests that they are very old. The pair of celestial bodies, according to NASA estimates, are about 10 billion years old, and their combined mass is about 75 times the mass of Jupiter.

If these brown dwarfs are lowcontent of the metal, then the researchers are sure that there are ancient exoplanets with the same composition. Therefore, researchers will start looking for old low metal exoplanets or other galaxies that orbit ancient low metal stars. Further studies of this population of brown dwarfs could provide answers to questions about how much the process of planet formation depends on the mass of metals in the composition.
