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.
A precursor to the Square Kilometre Array- the MeerKAT telescope - is being built right now and remarkable progress has been made in the last 12 months.
Star Trek: Discovery explores our corner of the block -- just a fraction of the galaxy. Some stars are better candidates for intelligent alien life, and it may not be anything like we imagine.
Scientists say they now know that high energy cosmic ray particles that bombard Earth are coming from outside our galaxy. But the actual source still remains a mystery.
How exactly do the stars twinkle in the night sky? As it turns out, the answer is full of hot air... and cold air.
It's like one great big distillery up there.
What caused the Big Bang is still a mystery. And that's just one of the many unanswered questions, in spite of everything we do know about the birth of the Universe.
The Guardians of the Galaxy team are rocking the universe again in the latest volume of the science fiction blockbuster. But how does the science stand up to some number crunching?
