How to see the Lyrid meteor shower 2021 tonight
Good news to all amateur astronomers: the first major meteor shower of 2021 has arrived. Called the Lyrid meteor shower, the celestial spectacle is set to shoot streaks of light across the night sky during mid-April.
While not the most active shower of the year, you can still expect to see an estimated 18 fast and bright meteors each hour during its peak. However, the glare from a near-full moon (known as a gibbous moon) will make the meteors harder to spot than usual.
So, what is the best way of making sure you see the Lyrid meteor shower? What causes it in the first place? And when exactly should you look for it? All of this (and more) is answered below.

When can you see the Lyrid meteor shower 2021 in the UK?
The Lyrid meteor shower will take place between 13-29 April this year.
However, it will be most visible during its peak: the early morning of 22 April (you’ll have to stay up until after midnight to get the best views).
What actually is a meteor shower?
A meteor shower is a collection of space debris known as meteors that become visible in the night sky as they burn up in Earth’s atmosphere.
This debris – normally dust from a comet or asteroid – is often only the size of a grain of sand. But despite being tiny, it can travel at tremendous speeds (up to 66km/s), ensuring it shines brightly in the atmosphere.
The Lyrid meteor shower is caused when Earth’s orbit crosses path with the debris trail left by the comet Thatcher. The shower has been observed by humans for over 2,500 years, but the comet itself hasn’t been seen since 1861 – Thatcher’s orbit around the Sun is so big it only crosses into the inner Solar System roughly every 415 years.
(In case you’re wondering: no, comet Thatcher is nothing to do with former Prime Minister Margaret Thatcher. Instead, it’s named after astronomer A.E. Thatcher, who first spotted the comet).
How can I see the Lyrid meteor shower 2021?
Don’t worry too much about searching for one particular point in space – Lyrid meteors will be visible all across the night sky. To give yourself a wide a field of vision, it’s best to ditch the telescope and rely on your eyes alone.
After spotting a few streaks of light across the sky, you’ll notice the meteors all originate from the same area: the constellation of Lyra, which contains the star Vega. To find the star, we recommend using a stargazing app such as SkyView Lite (free on Android and Apple devices).

However, don’t spend your time looking directly at this exact area (known as the radiant) – meteors may originate from here, but they’re unlikely to be visible at this exact spot.
The later you stay up on the night of 21 April, the more meteors you’ll probably see. That’s because the radiant will appear higher in the sky and fewer meteors will be hidden behind the horizon.
Before trying to spot the shower, it’s best to let your eyes adjust to the darkness for at least 20 minutes (looking at your phone during this time could scupper your night vision). Keeping away from city lights will also help your visibility.
What’s the difference between meteors, comets and asteroids?
Although often used interchangeably (particularly in bad sci-fi), there are key differences:
- Meteors are the bits of rock and dusk that break away from comets and asteroids. A meteorite is what falls through the Earth’s atmosphere.
- Asteroids are masses of rock that orbit the Sun in the asteroid belt between Mars and Jupiter.
- Comets, like asteroids, orbit the Sun. However, they’re made of ice and dust rather than rock.
