GS-z13-1, marks the earliest sign yet spotted of the era of cosmic reionization at 330 million years after the Big Bang.

Decades of constant X-ray emission from the Helix Nebula’s white dwarf suggest debris from a Jupiter-sized planet steadily rains upon the star.

A planetary nebula in Sagittarius, 3000 light-years away, features waves 100 billion kilometres high, caused by supersonic shocks from a hot star's stellar winds. Hubble's image of planetary nebula IC ...

Using advanced simulations, the researchers propose that these planets emerge from distinct rings of planetesimals, providing fresh insight into planetary evolution beyond our solar system.

But the Helix Nebula is a tricky one to study. As a planetary nebula, its center contains a white dwarf, a type of star known for emitting weak and inconsistent X-rays. The neutral gas and dust ...

Stunning new imagery and other data from NASA’s James Webb Space Telescope (JWST) reveal new details about a pair of enigmatic infrared ring structures accompanying a distant planetary nebula. The new ...

Asteroids do offer us the opportunity to stave off at least one kind of planetary disaster because, like all objects in space, they follow a clear and largely predictable orbit. An asteroid impact ...

The Helix Nebula is an example of a planetary nebula. Though it looks like a bubble or eye from Earth's point of view, the Helix is actually a trillion-mile-long tunnel of glowing gases. This Hubble ...
