Ancient Mars was warm and wet, suggest UCL-led research team

After the recent discovery of extensive fossilized riverbeds on Mars, the idea that the Red Planet could have been habitable 4 billion years ago has gained more traction.


In theĀ study, the scientists used very high-resolution imagery to determine the riverbeds on Arabia Terra. A resolution of 6 metres per pixel, compared to the 100 metres per pixel, confirmed that the features were created by giant rivers on Ancient Mars. The researchers now hope to study the features in greater detail.

Here are some questions:

  • Could life still exist on Mars in a form we do not expect?
  • What else do we know about Ancient Mars? How do we confirm it?

  1. I’m amazed, I have to admit. Rarely do I encounter a
    blog that’s both equally educative and engaging, and let me tell you,
    you have hit the nail on the head. The issue is
    an issue that too few folks are speaking intelligently about.
    Now i’m very happy that I stumbled across
    this in my hunt for something relating to this.
