When were the first galaxies born?
The Earth is a planet, orbiting the Sun. The Sun is a star – a giant ball of hot gas, emitting light and heat. The Sun is one of the few hundred billion stars in our Milky Way galaxy. And the Milky Way is one of the hundred billion or...

How do solar explosions work?
The Sun is a star. Not many people know that. It’s a star like all the other stars in the night sky. Or, put differently: all the stars in the night sky are suns like our own. So why are the stars tiny pinpricks of light, while the Sun is...

How are ALMA images created?
ALMA measures millimeter waves from the sky. These millimeter waves are emitted by cold dust clouds in the Universe. The clouds are so cold that they don’t produce visible light. They’re completely dark. With a normal telescope, you can’t see them. But ALMA can detect their invisible radiation. But...

How are the antennas moved around?
The huge array of 66 ALMA antennas is located at the Chajnantor Plateau in the north of Chile, at 5,000 meters altitude. The site is known as the AOS – the Array Operations Site. Because of the high altitude, the air at the AOS is very thin. There’s not much...

ALMA finds planet-on-the-move in outer part of planet-forming disk
ALMA has discovered a new planet, orbiting a distant star. But not by actually seeing it – the planet is too small to detect from Earth. Instead, ALMA saw the planet’s tracks in the dusty disk that whirls around the star. It’s like finding the Invisible Man through his...

ALMA uncovers a hidden black hole
Black holes are the most mysterious objects in the Universe. Their gravity is dangerously strong. They suck in everything that comes too close. Moreover, they don’t emit any light. As a result, they’re completely invisible. Still, there are ways to detect black holes. That’s because they exert a tell-tale...

Milky Way’s black hole surrounded by ring of not-so-hot gas
There’s a big black hole in the core of the Milky Way. A huge region in space where gravity is so strong that nothing can escape, not even light. This monster black hole is four million times more massive than our Sun. Luckily, it’s also very far away: 26,000...

Baby star blows gas into space at two different speeds
If you topple a bottle of water, the liquid flows out very fast. But turn over a container of treacle, and it takes ages to empty. So what could be going on if you see a fast and a slow flow at the same time? Astronomers faced a similar...
