Where specialized algorithms fail to classify star-borne pulses, human volunteers with just a little training can step in.

Now out in space for more than two years, the James Webb Space Telescope is a stunningly sophisticated instrument.

A type of eclipse is crucial for measuring what’s in the atmospheres of planets orbiting distant stars.

An instrument on the Europa Clipper mission might be able to detect biological cells from space.

Your phone can’t take a perfectly clear picture of a solar eclipse like a professional camera can, but there are lots of other creative directions you can take to capture the rare moment.

Some ancient texts record what were likely dying stars, faintly visible from Earth. If close enough, these events can disturb telescopes and even damage the ozone layer.

Europa Clipper will contain a plaque that celebrates humanity’s relationship with water and a decades-old tradition of searching for life outside Earth.

The eclipse will allow scientists to get rare measurements of the Sun’s atmosphere.

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.
