Three newly discovered bodies of liquid water deep beneath the south polar ice cap on Mars have planetary scientists intrigued.
There seems to be a network of underground bodies of liquid water at Mars’ south pole.

New findings boost chances of finding life on Mars, but there are better candidates in the solar system.
Considering what we know about the key ingredients for life's formation on Earth, here are three explanations for how this process may have occurred on our sister planet.

News that Venus may harbor life has swept the globe. So how do we find out for sure? A planetary scientist explains what's next.

The discovery of phosphine in the acidic clouds of Venus can't be explained by any known chemical or geological processes.

Sometimes it is difficult to take a photograph of an exoplanet because the star illuminating it is too bright. Now there is a new 'deluminator' telescope that can block out the extra light.
Is there anybody out there?
From the subatomic to the cosmic, don't think for a second that we're at the end of scientific history.

K2-18 b is now the exoplanet most likely to be habitable.
Much of Mars’s surface is covered by fine-grained materials that hide the bedrock. The above bedrock is mostly exposed and it is in these areas that micrometeorites likely to accumulate.

It's established Mars was once a planet with surface-level water. So with multiple MARS missions starting next year, the key to seeking out martian life may instead lie in the contents of its 'dust'.
Realising the silence of outer space was what made us appreciate our precarious position down on this pale blue dot – so beginning our obsession with extinction.
We haven't heard anything from alien civilisations, but perhaps they've heard us.
The fifth episode of the To the moon and beyond podcast series explores where we will be travelling in 2069.
A Sept. 20 citizen “raid” on Area 51, a secretive military installation long fancied to hold alien remains, has drawn worldwide interest.
As more than a million people have indicated plans to partake in a citizen 'raid' on the famed Area 51 to 'see them aliens,' a scholar on the search for extraterrestrial life weighs in on the hype.
Varied terrain on Europa.
Whether anything could live in Europa's subsurface ocean depends on what kind of salt it contains. Now scientists have found out.
Relative sizes of planets that are in a zone potentially compatible with life: Kepler-22b, Kepler-69c, Kepler-62e, Kepler-62f and Earth (named left to right; except for Earth, these are artists’ renditions).
The ancient question 'Are we alone?' has graduated from being a philosophical musing to a testable hypothesis. We should be prepared for an answer.

The space industry and global interest in all matters inter-planetary is growing.

We will never see 'Oumuamua again, and we may never know exactly what it is. But with the right kind of media coverage it could inspire some kids to take up a career in science.
Once people get there, Mars will be contaminated with Earth life.

NASA's InSight Mars lander touches down Nov. 26, part of a careful robotic approach to exploring the red planet. But human exploration of Mars will inevitably introduce Earth life. Are you OK with that?
