SciShow Space explores the latest mission to search for extraterrestrial life, and the mission of two tiny satellites that aims to make space travel safer.

Astronomer Aomawa Shields searches for clues that life might exist elsewhere in the universe by examining the atmospheres of distant exoplanets. When she isn't exploring the heavens, the classically trained actor (and TED Fellow) looks...

New Horizons went into safe mode and lost a few days of science observations. And there seems to be some confusion over whether there are aliens on Comet 67P.

As the number of _potentially habitable" planets that astronomers find continues to rise, we seem ever closer to answering the question, _Are we alone in the universe?" But should we be looking for life elsewhere? If we were to find life...

Life on Earth requires three things: liquid water, a source of energy within a habitable range from the sun and organic carbon-based material. But life is surprisingly resilient, and organisms called extremophiles can be found in hostile...

Deep in an archive in Columbus, Ohio, there's a slip of paper with a bunch of random-looking letters and numbers printed on it called the ‘Wow' signal.

Aliens have invaded ancient history: they've cropped up in humanity's past through popular television and movies, displacing facts with absurd yet commonplace beliefs like "aliens built the pyramids." Archaeologist Sarah Kurnick...

In the 1970s, launched aboard a space probe was what is considered one of the most important scientific diagrams ever created. If found by extraterrestrial life, the plaque explains details about the human race and where we are in the...

The Fermi Paradox refers to the apparent contradiction between the high probability of extraterrestrial life in the universe and the lack of evidence or contact with such civilizations. Named after physicist Enrico Fermi, the paradox...

Why don’t we go live on Saturn’s moon Titan? What would it mean if we found life elsewhere? How did life get its start on Earth? NASA’s chief scientist Jim Green and astrobiologist Lindsay Hays discuss these and other audience questions...

Phobias can be debilitating, but some of them are simply bizarre. Here are the strangest things that some poor people are actually terrified of.

The Fermi Paradox raises the question of why, despite the vast number of potentially habitable planets, we have not yet found evidence of intelligent extraterrestrial life. This video explores possible explanations, including the rarity...

Kepler-452b, a planet located 1,400 light-years away from Earth, was announced on Thursday as the most Earth-like planet ever found by NASA, which is naming it 'Earth 2.0'.

Is there other life out there in the universe? Do aliens really exist? If so, then where are they all?! In this most epic of episodes, Dom has his favourite film (Aliens) interrupted by an extraterrestrial visitor - how very...
