James Webb has spotted extremely distant galaxies formed soon after the Big Bang, but are they old or young? Or is this the wrong question to ask?

Earth is moving through a bit of space where three streams of debris intersect with our orbit. These streams will give birth to the stars of this weekend’s show.
Astronomers have discovered the first dormant black hole outside of the Milky Way. These black holes are not absorbing matter from a nearby star, making them incredibly hard to find.
The unusual planetary system has a host star orbited by two giants. One has an incredible odd route around its star. And the other (unlike our own gas giants) is hellishly hot.
Why is the universe 13.8 billion years old, but 93 billion light-years across? It’s all about how light travels through the cosmos.
Life on Earth has dramatically changed the chemistry of the planet. Astronomers will measure light that bounces off distant planets to look for similar clues that they host life.
Long before the James Webb telescope brought us these deep field images, artists have been capturing notions of space.
Through direct comparison with images from Hubble, you can start to see the exquisite detail and clarity Webb provides.
NASA released five new images from the James Webb Space Telescope, revealing incredible details of ancient galaxies, stars and the presence of water in the atmosphere of a distant planet.
Even experts were not prepared for the crispness of the new images from the James Webb space telescope.
Have astronomers finally found evidence of intelligent found life beyond Earth?
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.
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 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.
The object has a highly unusually long rotation period, and was found in an area we call the neutron star ‘graveyard’.
Could the Tau Herculid meteor shower put on a spectacular show next week? Only time will tell.
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.
Fanaroff is one of the key individuals responsible for the current growth and strength of astronomy in South Africa.
Sagittarius A* lies in the southern sky, passing directly above South Africa.
Sagittarius A* is a massive black hole at the center of the Milky Way. Now that astronomers have imaged it, they can begin to learn more about black holes within other galaxies across the universe.
