Study: The sun will swallow the earth... and our planet will melt within one day
One of the studies revealed that the sun will turn into a red giant that swallows the planets Earth and Mars, and the planet will melt within less than a day due to an epic explosion of the sun.
According to the study published in the journal Nature Astronomy, the sun will “die” within about 10 billion years, and large stars such as the sun begin to “die” when they burn all their hydrogen fuel, and “Russia Today” quoted the study that at this stage the sun will expand and become A red giant, and scientists believe that this stage will occur to the sun within five billion years.
The study indicated that when the sun completes the red giant stage, it will become a white dwarf, and then end up as a planetary nebula.
This means that our star will turn into a glowing shell of hot gas.
This type of nebula is very common throughout the observable universe, and can be observed by its brightness from distances that may reach millions of light years.
In another description, the New York Times said in a previous report, that when our sun enters its death throes in about five billion years, it will burn our planet and then collapse dramatically and turn into a dead ember known as a white dwarf.
The Nature study stated that the sun is expected to expand so much that it will swallow up Mars and Earth as it transforms into a red giant, and scientific predictions indicate that humans will die before that time unless humans find a way to leave the planet and live elsewhere.
According to another study conducted by an international team of astronomers, it is expected that the sun will become brighter by 10% every billion years, and this increase in brightness would end life on Earth, as the oceans would evaporate, and the surface would become too hot for water to form.
Earth will look like Venus trapped in a stifling atmosphere of carbon dioxide, and then it gets worse.
And Russia Today adds, if the expansion of the sun reaches our planet, the Earth will melt in less than a day, and even if the expansion of the sun stops for a short period, the intense energies emitted from the sun are strong enough to vaporize the rocks, and those energies will only leave behind the dense iron core. for planet earth.
According to a report published by ScienceAlert, humanity has only a billion years left unless it finds a way to get away from this Earth, because the brightness of the Sun increases by about 10% every billion years, explaining that the increase in brightness will end life on Earth, the oceans will evaporate and the surface will become so hot that Water cannot be formed.
According to Sciencealert's report, many previous studies suggested that our sun would shrink from a red giant to a white dwarf and then end as a planetary nebula. When the star dies, it ejects a mass of gas and dust into space.
The envelope can be up to half the mass of the star.
This reveals the star's core, and the hot core will make the ejected envelope of the star shine brightly for about 10,000 years very brightly.
