Stories about: white dwarfs  

The stars, located at the heart of a planetary nebula dubbed Henize 2-428, will crash some 700 million years from now

This structure is produced by a fortuitous alignment of celestial objects

Previously, astronomers thought their mass levels were consistent

The finding could help test the theory of general relativity

The instrument is installed aboard the International Space Station

New study overturns older hypothesis on how these blasts occur

A triple star system provides optimal conditions for analysis

New study finally sheds some light on their origins

These structures will appear billions of years from now

Events such as this are thought to produce gravitational waves

Albert Einstein was the first to propose these waves existed

They are apparently capable of wrapping space around them

White dwarfs in this structure are extremely old, astronomers say

Studies show that no single mechanism can account for all these objects

Astronomers see four white dwarfs devouring their planets

The view was collected by the Hubble back in 2002

The object may be in Earth's temperature range, experts say
