Astronomers spotted a potential Earth-size rocky world orbiting a white dwarf, suggesting a future in which our planet outlives its star. By Jonathan O’Callaghan In six billion years the sun will ...

The explosion of the sun is a threat straight out of science fiction, but could it really happen, and if so, what would the consequences be for our solar system? When a star explodes, it forms a ...

Unlike giant stars that explode into a supernova and collapse into a black hole, a medium star like Earth's sun just keeps on ...

TL;DR: Researchers from the University of Tokyo and NASA used supercomputers to predict Earth's habitability will end around 1 billion years from now due to increasing solar heat. The Sun's expansion ...

(THE CONVERSATION) The Sun will someday die. This will happen when it runs out of hydrogen fuel in its core and can no longer produce energy through nuclear fusion as it does now. The death of the Sun ...

LONDON (Reuters) - Astronomers have discovered the first known planet to survive its "red-giant" phase, a period when an aging star expands and engulfs bodies orbiting it. The discovery of the ...

First, let’s discriminate between expansion and expulsion. Expansion happens because the thermal pressure from the increased energy production in the Sun’s interior exceeds the gravitational force ...

How big it is: 865,000 miles (1.392 million kilometers) across How far away it is: 93 million miles (150 million km) What type of star it is: A yellow dwarf star The sun is the star at the center of ...

A 2020 microlensing event was caused by a planetary system with an Earth-like planet and brown dwarf. The star type was uncertain. The team has determined that the star is a white dwarf, a system ...

Massive stars do not live long. There are several candidates for the biggest star in the universe. One of them, VY Canis Majoris, is over 1,500 times the width of the sun. If it were placed in our ...
