E-merlin Facts For Kids
e-MERLIN is a super team of radio telescopes across England that link up like friends holding hands to see tiny details in space, like baby stars and black holes, helping us learn universe secrets.
About this topic
Run from Jodrell Bank Observatory in Cheshire, e-MERLIN catches invisible radio waves from space. These waves come from cool places like exploding stars or distant planets. The telescopes stretch over 217 kilometers, acting as one giant dish as big as a small country. This setup gives sharp pictures, almost as clear as the Hubble Space Telescope's views of colorful galaxies.
Because they team up, e-MERLIN helps scientists learn secrets about our universe.

📘 The Telescopes
These telescopes listen to radio waves at frequencies from 151 MHz to 24 GHz. That's like tuning into different radio stations from space. By linking them over 217 kilometers—the longest distance between any two—the array sees tiny details, down to 40 milliarcseconds at 6 cm waves. That's sharper than many eyes on Earth!
Working as a team, called an interferometer array, they create pictures clearer than one telescope alone.
🔎 Merlin's Beginnings
At first, it was called MTRLI, but soon became MERLIN—Multi-Element Radio-Linked Interferometer Network. They built new telescopes, like Knockin, and added microwave links and a computer to mix signals. By 1976, the first parts were ready, and real sky-watching began in 1980.
This teamwork made MERLIN a star-spotting powerhouse, helping discover hidden space wonders.
🧭 The E-merlin Upgrade
There were money worries—a big shortfall scared everyone. But experts talked it over at meetings and pushed it up the list. They saw e-MERLIN as key for UK space studies and future giant projects like the SKA.
By agreeing to share costs, they moved forward. The upgrade turned MERLIN into e-MERLIN, a world-class space viewer ready for new discoveries.
💡 Amazing Discoveries
Another cool find came from studying Messier 87, a giant galaxy that glows brightly in radio waves. e-MERLIN revealed hidden details in its jets of speedy particles shooting out from a black hole at the center. These jets stretch millions of light-years!
It has also watched faraway quasars, super-bright centers of ancient galaxies powered by black holes. By linking with other telescopes, e-MERLIN helps map gas clouds and measure star positions with amazing accuracy.

Frequently asked questions
What is e-MERLIN?
e-MERLIN is a super team of radio telescopes spread across England that work together like friends holding hands to make one huge telescope. This giant eye in the sky catches invisible radio waves from space to spot tiny details like stars being born or black holes. It is run from Jodrell Bank Observatory in Cheshire.
How do the e-MERLIN telescopes work together?
e-MERLIN uses up to seven special radio telescopes spread over 217 kilometers across England, acting as one giant dish as big as a small country. They form an interferometer array that listens to radio waves at frequencies from 151 MHz to 24 GHz to create sharp pictures. This teamwork gives views almost as clear as the Hubble Space Telescope.
What is the biggest telescope in e-MERLIN?
The biggest telescope in e-MERLIN is the giant Lovell Telescope at Jodrell Bank, like a huge spinning dish catching whispers from space. Others include the Mark II, Cambridge, Defford, Knockin, Pickmere, and Darnhall telescopes in different spots across England.
How did MERLIN start?
In 1973, scientist Henry Proctor Palmer had the idea to connect telescopes at Jodrell Bank with faraway ones using radio links. It started building in 1975 and became MERLIN—Multi-Element Radio-Linked Interferometer Network—by adding new telescopes and microwave links. Real sky-watching began in 1980.
What is e-MERLIN's upgrade from MERLIN?
In 2008, scientists planned e-MERLIN by swapping old phone-line links for fast internet fibers to make pictures sharper and faster. They overcame money worries by sharing costs and saw it as key for UK space studies. This turned MERLIN into a world-class space viewer.
What amazing things has e-MERLIN discovered?
e-MERLIN teamed up with Hubble in 1998 to spot the first Einstein ring, a circle of light bent by gravity around a galaxy. It revealed hidden details in jets of speedy particles from a black hole in Messier 87 that stretch millions of light-years. It also studies faraway quasars and maps gas clouds.
