An astronomer takes us on a tour of the universe to learn about the birth of stars and planets and how they get their spin.

Birds and dinosaurs lived together for millions of years, but only toothless birds survived the asteroid impact that upended life on Earth.
Meteor impacts are an inevitable part of being a rocky planet in space. The craters they leave behind are a window into the tumultuous history of Earth.
Rubble pile asteroids are like giant space cushions, floating around the Solar System for billions of years. Here’s what that means for planetary defence.
Starting at the surface, you would have to dig nearly 2,000 miles before reaching the Earth’s core. No one could survive that trip – and the 10,000-degree F heat once there would vaporize you anyway.
A new photo taken on the Artemis I mission shows Earth isn’t a sealed spaceship, but is in dynamic interchange with the cosmos.
Blue Marble is the last photograph of the whole Earth taken by an actual human using analogue film: developed in a darkroom when the crew returned to Earth.
Scientists have uncovered the long-term history of our receding moon. And it’s not from studying the moon itself, but from reading signals in ancient layers of rock on Earth.
When the Orion Crew Capsule orbits the Moon there will be no one on board. But the mission will mark a key step in bringing humans back to Earth’s dusty sidekick.
Lovelock’s Gaia hypothesis suggested that Earth could be considered a single, self-regulating organism.
NASA, NOAA and SpaceWeather say a coronal mass ejection will reach Earth this week. It has the potential to knock out communications in some parts of the world.
A biologist explains how researchers nail down the age of ancient fossils thanks to a physical process called radioactive decay.
By tracking a meteorite found in Morocco back to its origin in an asteroid crater on Mars millions of years ago, scientists can learn more about how the planets formed.
The Earth has had at least five major ice ages, and humans showed up in time for the most recent one. In fact, we’re still in it.
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.
A curious kid asks: Why does it matter if Pluto is a planet or a dwarf planet?
There are many bodies in the solar system we can’t easily access. But observations of their winds and sediments reveal a surprising amount.
Current trends suggest that powerful nations are defining the rules of resource use in space and satellite access in ways that will make it hard for developing nations to ever catch up.
The Earth is a resilient planet, but people are altering it in ways that may take centuries to reverse.
With an antenna, a laptop and some software, you can take a picture of Earth from space.
