Scientists have reportedly identified thousands of solar systems where alien life could be watching our planet.
The newly identified star systems are apparently quite close to us on a cosmic scale, meaning that life on them would be able to see our planet when we cross in front of the sun.
Planets situated around the star systems would possibly be able to distinguish if our planet held life – and could already know.
By watching distant exoplanets transit – or cross – their own sun, astronomers can interpret the backlit atmospheres.
If they harbour intelligent life, the chemical signatures can be identified and aliens could have done this to our planet.
Out of the 2,034 newly identified star systems, 1,715 of them could have spotted Earth since human civilisation began in the last few thousand years.
The rest of the systems will be able to see us in around 5,000 years.
75 of the discovered stars are within 100 light years of us which means our radio waves would have reached them by now.

There are a variety of stars that scientists have identified in their new discovery, all of which have similar characteristics found throughout the Milky Way.
A lack of data on most of them means that scientists can not yet say what their conditions might be like or if they’re similar to our planet.
But they estimate that there potentially could be 29 habitable worlds that could see Earth when we’re positioned in front of the sun.
Scientists have said that there are many stars close enough that civilisations living around them would be able to identify us as an “interesting planet”.
