Did you know that when you look up at the night sky, you’re actually looking back in time? It might sound like science fiction, but it’s real! Light takes time to travel, so when we see stars and galaxies, we’re seeing them as they were thousands, millions, or even billions of years ago. For example, light from the Sun takes about 8 minutes to reach Earth — but light from stars on the far side of our galaxy can take up to 75,000 years to get here. And the most distant galaxies? Their light left them long before humans even existed! 

Even cooler, not all light can be seen with our eyes. Some galaxies shoot out enormous jets of superheated plasma that glow brightly — but not in visible light. They shine in radio waves, which special telescopes can detect. 

I’m a theoretical astrophysicist — someone who uses maths and computer models to figure out how space works. I study the radio waves from those giant galactic jets to understand how they form, how they change over time, and what they tell us about the galaxies that made them.  

Space is full of amazing mysteries, and I’m so excited to explore some of them with you!
