So bright you'll be able to see it without a telescope, a “new” star system, T Coronae Borealis, will become visible for the first time in 80 years between now and September. Abigail Beall explains where to spot it

Some people find the scale of the universe existentially frightening, but here's why you should take it as a source of comfort

See the circle of galaxy clusters and voids that surround us in this map of the nearby cosmos, extending 200 million light years in each direction

Our arm of the Milky Way is filled with older, metal-rich stars. New research suggests these might provide the best conditions for life to form on their planets

We may never know what lies beyond the boundaries of the observable universe, but the fabric of the cosmos can tell us whether the universe is infinite or not

Geocentrism, the idea that everything in the universe revolves around Earth, has long been disproven, but this episode of Dead Planets Society is bringing it back with cataclysmic consequences

The Chinese lunar spacecraft Chang’e 6 has touched down in Inner Mongolia, bringing back to Earth the first rock samples from the moon's far side

When the planet Mercury formed 4 billion years ago, conditions may have been just right to form a thick layer of diamonds below its surface

The Earth-sized storm on Jupiter known as the red spot was thought by many to have been first observed in 1665, but it turns out that may have been an entirely different enormous storm, with today's storm dating back only to 1831

It has long been thought that young stars forming near each other will be aligned in terms of their rotation, and observations from the James Webb Space Telescope have offered confirmation

Saturn’s moon Titan has coastlines matching ones on Earth that have been carved by waves, hinting that Titan’s hydrocarbon seas and lakes also has them

The New Horizons mission to Pluto, now zooming out of the Kuiper belt, has made a discovery that could upend what we know about where the solar system ends

The chemical composition of Pluto and Triton suggests they originated in the same region of the outer solar system before the latter was pulled into Neptune’s orbit

The theory of relativity predicts black holes should be able to form from light alone, but incorporating quantum effects makes it impossible

Using the James Webb Space Telescope, astronomers have increased the number of known supernovae in the early universe by a factor of 10 and found the most distant one ever confirmed

Minuscule black holes that formed right after the big bang could have had a strange property called colour charge, and spotting them could help unravel the mystery of dark matter

These stunning photographs are some of the winners of this year’s Milky Way Photographer of the Year competition

How could we tell the difference between an ordinary black hole and one connected to a tunnel through space-time?

Faster-than-light warp drives are theoretically possible to build, and if aliens are using them, we should be able to detect the gravitational waves produced when one goes wrong
