The search for planets suitable for life, similar to the Earth in its conditions, is among the topics of exciting astronomical research, and one of the most attractive topics for the general reader, so we find from time to time an important research, drawing or a new report in this field.

In the most recent of these reports, published by the British newspaper "The Independent", writer Andrew Griffin said that scientists have found that cosmic dust would be evidence to know whether other planets are inhabited by aliens or not.

Dust and life conditions

Airborne dust on these planets appears to be the main factor determining the conditions of life there, and whether or not they are suitable for living.

But at the same time, it would obliterate the indicators of life from other planets, which means that scientists will not be able to determine the suitability of housing when they look around the universe in search of other worlds.

The writer mentioned that the new research indicates that those planets that contain large amounts of cosmic dust transported by the air, may be habitable even when they are further away from their star.

In turn, this means that these planets will theoretically be the best alternative to life far from Earth.

The writer pointed out that the cosmic dust works to change the climate of the planets so that they are more able to deal with the severe conditions lurking throughout the universe.

The discovery indicates that planets that were deemed uninhabitable due to their conditions may actually be better suited to life than scientists previously thought.

For their part, the researchers urged - in the new study, published in the journal "Nature Communications" - those who search in the universe for these planets, to consider dust as a possible major indication of the planet's viability.

Much of astronomical research and space missions has researched the conditions for life in exoplanets - the Kepler telescope (NASA).

Consider dust

Many of the planets that have been found as potential habitats for aliens orbit the stars smaller and cooler than our sun, known as "dwarves-M", through "states of rotation in a synchronous orbit", so that the planet is divided into day and night permanently.

This is a major problem for any form of life, because it means that every aspect of the planet is likely to experience more severe conditions.

However, the researchers found that large amounts of airborne dust would cool the hottest side, as well as warm the cooler night side.

Scientists from the University of Exeter, the Bureau of Meteorology, and the University of East Anglia also urged those looking for cosmic dust to search for it in the same way that they search for other vital signs of life.

They also warned that the same thing that makes these worlds habitable can also prevent us from seeing them correctly.

Dust may also block

For his part, said Manoj Joshi of the European Energy Agency that "airborne dust may keep the planets habitable, but it also obscures our ability to find indicators of life. These effects need to be taken into account in future research."

The author stated that the scientists reached these results by simulating the outer planets the size of the Earth using climatic models that allowed them to see how natural dust could change the conditions in those worlds.
