A little less analogue, and a lot more crap.

Amazing.

The exocomets' tails absorb a tiny amount of their host stars' light - and the absorption changes with time as the comets speed and slow.
With patient observation, the pair came up with seven new exocomet sightings.

I didn't think observation was possible even now, but I was wrong


The comet - a 100km-wide body made of rock and ice - was ripped apart and destroyed by the heat of the star.
Its demise was witnessed by observers using the giant Hobby-Eberly Telescope in Texas to observe the star Lk H-alpha 234, which is 3,200 light-years away.

If I have done the maths correctly, thats like observing something the size of a 20 pence coin from the other side of the planet
