Exploding stars send out powerful bursts of energy − I’m leading a citizen scientist project to classify and learn about these bright flashes

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

Looking to photograph a solar eclipse with your smartphone? Try these features and think about creative angles

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.

Exploding stars are rare but emit torrents of radiation − if one happened close enough to Earth, it could threaten life on the planet

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.

Solar eclipses result from a fantastic celestial coincidence of scale and distance

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.

Total solar eclipses, while stunning, can damage your eyes if viewed without the right protection

Now’s the time to get your hands on a pair of eclipse glasses in preparation for April’s display of celestial wonder.

April’s eclipse will mean interruptions in solar power generation, which could strain electrical grids

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.

Why does a leap year have 366 days?

Humans have synced their calendars to the sun and moon for centuries, but every so often, these systems need a little correction.
