Life could exist in another solar system in a different part our galaxy. Or in another galaxy far away. We don't have the perfect technology yet to study such far away places but we're still trying.

Using AI to search for ET might help us find things we couldn't even imagine we should look for, but to succeed we also have think critically about how we create and use that technology.
New research may help us to look for messages from alien civilisations.
Scientists looking for signs of alien life from the mystery object passing through our Solar system say they've found nothing "so far".
Astronomers in Puerto Rico have picked up signal from a faint star that's not like anything they've seen before.
Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
Mysterious radiation that appears to come from star HD 164595 is more likely to have a terrestrial origin.
Some argue that it would be impossible to understand an alien language, as it wouldn't have the same grammar as humans use. But others are more optimistic.
Complex life may be rare in the universe because most planets become either too hot or too cold before life has a chance to get a foothold. This might explain why we have yet to bump into E.T.
In a world of blogs, twitter and open data, scientists need to think again about how they'd communicate a discovery of alien life.
From a flyby of Pluto to the search for extrasolar planets and gravitational waves, 2015 was a monumental year for space news.
A hint of oxygen and a whiff of methane in a distant exoplanet's atmosphere may be the first evidence we discover of alien life.
The chance that Kepler has spotted construction of a Dyson sphere are very low but it could also be the ruins of such a structure.
There's a lot of speculation about a star behaving strangely in our galaxy. But even if it's not evidence of alien intelligence, it's sure to be an amazing discovery.
Kepler-452b's discovery last week has raised the perennial question: are we alone in the universe? While the find's scientific import is huge, it also poses questions that go to the heart of religion.
Given Earth is our sole example of life in the universe, it's hard to know what we're looking for elsewhere in the cosmos.
Simple mathematics suggests that if there are aliens out there, they should have reached us by now. So is it really worthwhile trying to communicate with them?
Why the Breakthrough Listen project is a step in the right direction in our hunt for life beyond Earth.
The Parkes radio telescope is part of the US$100 million search for life elsewhere in the universe, but the investment will also benefit other space research at The Dish.
The Conversation organised a public question-and-answer session on Reddit in which Seth Shostak, senior astronomer at the SETI Institute, explained why searching for intelligent life is so important and…
