The red dwarf star, called AU Microscopii, or AU Mic, is located outside of our solar system, 32 light-years from Earth, which is relatively close. It’s home to one of the youngest planetary systems ever observed, and the star is less than 100 million years old, as per CNN.

Scientists explain how Butterfly Nebula got its wings
Updated : 3 years, 1 month ago IST
Planetary nebulae form when red giant stars expel their outermost layers as they run out of helium fuel, becoming hot, dense white dwarf stars that are roughly the size of Earth. The material that was shed, enriched in carbon, forms dazzling patterns as it is blown gently into the interstell

Planetary system's second Earth-size world discovered
Updated : 3 years, 2 months ago IST
Using data from NASA's Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star, the range of distances where liquid water could occur on a planet's surface. The world is 95% Earth's size and likel

Astronomers find that two exoplanets may be mostly water
Updated : 3 years, 2 months ago IST
A team led by UdeM astronomers has found evidence that two exoplanets orbiting a red dwarf star are "water worlds," planets where water makes up a large fraction of the volume. These worlds, located in a planetary system 218 light-years away in the constellation Lyra, are unlike any planets

Coventry [England], February 10 (ANI): A white dwarf is known to be a small very dense star that is typically the size of a planet. It is formed when a low-mass star has exhausted all its central nuclear fuel and lost its outer layers as a planetary nebula. Astronomers at the University of W
