The dead of winter, when the longest night of the year takes place, has also traditionally been celebrated as a time of renewal and reverence.
Astrology and astronomy were once practiced side by side by scientists like Galileo and Kepler. And they’re more similar than you might think.
It has been one year since the launch of the James Webb Space Telescope and six months since the first pictures were released. Astronomers are already learning unexpected things about the early universe.
Astronomers have unpacked the mystery of how one star’s death created the nebula NGC3132 – never before seen in such detail.
The stars, planets and Milky Way we see at night are part of a wilderness shared across the globe and across centuries. But does BlueWalker 3 herald a night sky polluted with bright satellites?
A new particle accelerator has just begun operation. It is the most powerful accelerator of its kind on Earth and will allow physicists to study some of the rarest matter in the universe.
A new study of ‘solar twins’ shows a fundamental constant appears to be the same throughout our local galactic neighbourhood.
People across Australia and New Zealand will be able to catch the blood moon. Here’s how to get the best view.
The IceCube telescope near the South Pole has received a first glimpse into the core of the galaxy NGC 1068.
Believe it or not, this sort-of happened before in Earth’s history – and now we have the Moon.
The technology of an advanced alien civilization is likely to produce many signs that could be detected across the vastness of space. Two astronomers explain the search for technosignatures.
The binary star WR140 is surrounded by an astonishing array of nested shells of dust swirling into space.
In some African countries, astronomical research is quite developed.
The first ever planetary defence test is about to take place 11 million kilometres from Earth. All we can do is wait and see.
Newly discovered super-Earths add to the list of planets around other stars that offer the best chance of finding life. An astronomer explains what makes these super-Earths such excellent candidates.
A glowing blob in the sky known as “the cocoon” may be caused by pulsars in the Sagittarius dwarf galaxy.
The James Webb Space Telescope just released its first-ever exoplanet image. Here’s what’s so exciting about it, and what we can stand to learn.
A comparison of star-forming galaxies suggests, surprisingly, that dark matter and visible matter do interact – taking us closer to understanding what keeps the galaxies together.
Listening for events like black hole collisions is important in astronomy research – and the technology is only getting better.
