Not all planets orbit stars. Rogues float through the galaxy in darkness and are almost impossible to see.
A new method suggests we should aim to detect dark matter haloes by tracing galactic gas.
Surprising findings on an exquisite and huge star system in our Milky Way suggest future potential for an extremely rare gamma-ray burst. This event has never been observed in our galaxy.
Towns and cities create an orange glow on the horizon at night. It's so widespread that it even disturbs sea creatures.
China's Qixi Festival is a celebration of love based on the legend of a mortal who married a goddess, causing his furious mother-in-law to create a Milky Way to divide these two twinkling stars.
This observation means astronomers can now develop and test theories that explain how high-mass stars gain their mass.
There is a massive black hole in the center of the Milky Way galaxy. Measurements of star orbits near this black hole suggest that there may be a second companion black hole nearby.
New research shows the supermassive black hole at the centre of the Milky Way spat out an enormous beam of radiation 3.5 million years ago
Dung beetles are largely invisible. And yet without their vital activities, the world would have a lot more faeces in it.
The diameter of the Milky Way is a billion billion kilometres.
There's mounting evidence that increased lighting has a range of negative effects.
The Milky Way’s disc of stars becomes increasingly warped and twisted the further away they are from the galaxy’s centre.
A black hole is an object with such a strong gravitational pull that nothing, not even light, can escape from it.
The Gaia satellite has uncovered the remains of a galaxy buried deep in the Milky Way.
We are in the Milky Way. If you travelled on an extremely fast spaceship for more than two million years, you would reach our neighbour, the Andromeda galaxy. All other galaxies are even further away.
It's all about the strong gravitational field of the black hole.
Detailed information about stars in our galaxy could help us discover new exoplanets.
As galaxies get older they get rounder, and fall victim to the middle-aged spread that catches many of us humans here on Earth.
There could be thousands of black holes at the heart of the Milky Way.
Bigger galaxies tend to dominate the smaller, when the two collide. But the pending battle between our Milky Way and the Andromeda galaxy might be a much fairer fight than we previously thought.
