Discovery of 170 planets that wander and float in the interstellar cold

In our solar system, the planets revolve around the sun, following a well-defined orbit. But it is not uncommon to come across some wander in space. The astronomers, to see them, used an approach which is based on several images collected by a astral observation device. They think there are billions of large planets floating around aimlessly in the Milky Way.

The wandering planets come from the same clouds of gas and dust and form a solar system. However, it happens that these clouds cannot give rise to the constituent stars of the Milky Way. Despite this assumption, determining the exact number of wandering or starless planets remains a challenge. tough test.

The information available to astronomers does not allow them identify wandering planets like exoplanets. These planets are often seen as balls in space as light alters their bodies.

A list of wandering planets

Astronomers plan to collect samples from these planets. For this, they took advantage of the residual heat that emerges from the planets long after their birth. Thanks to this approach, they drew up an exhaustive list of wandering planets in the constellation Scorpio and Theophilus.

Astronomers said they measured the less travel, colors and lights emanating from millions of sources in a celestial zone. These initiatives enabled them to accurately determine the faintest objects in this area. Thus, on the 170 traces detected, only 70 turned out to be planets.

How to determine the characteristics of these planets?

To determine the size of a planet, scientists use the effects of gravitational lens or the oscillation of a star driven by a heavier one. As for the mass of the latter, it is more difficult to determine it. A wandering star perhaps shiny or not. This glow could be a sign that it is a large planet. The correspondence between the age of the zone and the planet allows to estimate the mass of the latter.

Despite the lack of information, the information collected will make it possible to continue research appalling the origin of the stellar wanderers. The density of these cosmic scoundrels reveals that the structure of their nucleus is not the only study method. This reinforces the idea that a large part of the planets are excluded. In any case, astronomers seem confident about the future of research, with the advent of more powerful instruments.
