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

Study of 'polluted' white dwarfs finds that stars and planets grow togethe
Updated : 3 years, 3 months ago IST
A team of astronomers has found that planet formation in our young Solar System started much earlier than previously thought, with the building blocks of planets growing at the same time as their parent star.

Astronomers discover 'cataclysmic' star pair with shortest orbit yet
Updated : 3 years, 5 months ago IST
Washington [US], October 6 (ANI): Astronomers at MIT and elsewhere have discovered a stellar binary, or pair of stars, with an extremely short orbit, appearing to circle each other every 51 minutes. The system seems to be one of a rare class of binaries known as a "cataclysmic variable," in

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
