New research may better explain the "string of pearls" around the remnant of a star, shedding light on a longstanding astrophysical mystery.

Sudden changes in space weather, such as solar flares, for example, could have significant health implications for crew and passengers.

Many people will see a dazzling eclipse this April, but these events are possible only because of the sizes and precise distances between Earth, the Moon and the Sun.

Determining whether or not life exists on another planet is an extraordinarily complicated – and expensive – scientific endeavor.

"With unprecedented glimpses into these disks surrounding young stars, the birthplaces of planets, JWST helps us uncover how planets form."

When the Moon blocks the Sun during an eclipse, utility suppliers have to pull power from the grid to make up for gaps in solar energy.

If we need to use forensic techniques in space, we’ll need to understand how things behave differently in microgravity.

The next generation of spacesuit needs to do more than simply protect an astronaut from the vacuum of space.

A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers.
