Exoplanet Orbiting a White Dwarf Star Gives Researchers Hope That Earth Might Escape Its Eventual Death
A planetary system anchored by a white dwarf star, located approximately 4,000 light-years away, provides astronomers with insights into what could happen to our Sun and Earth in about 8 billion years. This scenario unfolds if the Earth survives the Sun's transformation into a red giant, expected to occur in 5 to 6 billion years.

Scientists Observe Star Swallowing A Planet For The First Time
The discovery is significant since it shows what will happen to our Earth when the Sun morphs into a red giant and gobbles the four inner planet.

"Fluffiest Planet Ever": Scientists Discover "Marshmallow World" In Deep Space
Scientists are finding all sorts of weird worlds. They've now discovered a gas giant planet with the density of a marshmallow orbiting a cool red dwarf star located 580 light years from Earth. The planet, identified as TOI-3757 b, is the "fluffiest".

Scientists Believe 'Alien' Rock Hypatia May Reveal Details on Events That Lead to Supernova Explosions
Researchers are hopeful that an extraterrestrial stone found in the Egyptian desert could help shed some light on these spectacular events. The stone is named Hypatia. The experts have a hypothesis that the Hypatia stone originated with a star – a red giant star collapsed into a white dwarf star, which eventually “ate” the other star.

In a First, Astronomers Watch a Giant Red Star Explode Violently in Real Time
In a first for astronomy, researchers were able to see in real time the death by explosion of a giant red star using ground-based telescopes. They saw the star, located 120 million light-years away from Earth in the NGC 5731 galaxy, self-destruct in a dramatic event and collapse in a type-2 supernova.

First Giant Exoplanet Found Orbiting Extinguished Star
Astronomers have discovered a planet the size of Jupiter closely orbiting the smouldering remains of a dead star, the first time that an intact exoplanet has been discovered travelling around a white dwarf, according to research published Wednesday.

Images Of Red Giant Star Give Glimpse Of Sun's Future
Astronomers have for the first time observed the clearest and sharpest view yet of the surface of an ageing star with the mass same as that of the Sun, providing a glimpse of the solar body's future.

Astronomers Catch A Glimpse Of Sun's Future
A team of astronomers from Sweden has for the first time observed the clearest and sharpest view yet of the surface of a red giant, an ageing star, with the same mass as the Sun, demonstrating a glimpse of the Sun's future.
