It has taken eight months to test and calibrate all of the instruments and modes of the James Webb Space Telescope. A scientist on the team explains what it took to get Webb up and running.
Researchers used a radio telescope in New Mexico to study a particularly interesting fast radio burst.

Astronomers studying fast radio bursts recently discovered one that repeats, has a persistent radio signal and originated in a galaxy much closer than it should have.
The Moon often looks enormous when it first rises because of what is known as the Moon illusion.

The Moon illusion is what makes the Moon look giant when you see it rising over a distant horizon. An astronomer explains what causes this awe-inspiring trick of the mind.
Could the Tau Herculid meteor shower put on a spectacular show next week? Only time will tell.
Protons and neutrons in an atom’s nucleus can be arranged in different configurations, creating nuclear isomers.

Nuclear isomers are rare versions of elements with properties that mystified physicists when first discovered. Isomers are now used in medicine and astronomy, and researchers are set to discover thousands more of them.
Without Dr Bernie Fanaroff, the SKA might never have come to South African shores.

This year, two groups of astronomers plan to send messages containing information about humans and the location of Earth toward parts of space they think may be home to intelligent life.
The First Astronomers shares the extensive star knowledge of First Peoples worldwide, stretching back millennia to reclaim so-called Western discoveries and highlight the strength of oral traditions.
The Hubble Space Telescope was born from a previous decadal survey. What leaps forward will come from this one?
