ESA released stunning images of an ancient river in Nirgal Vallis that once flowed on Mars
By studying the surrounding craters, the branching remains are said to be between 3.5 and 4 billion years old
Detailed images of Mars reveal an ancient river that once flowed on the red planet.
Spanning nearly 435 miles across the surface, the valley stream is named Nirgal Vallis and experts said it was shaped by flowing water and impacts.
By exploring the characteristics of the surrounding craters, the European Space Agency has estimated the system’s age to be between 3.5 and 4 billion years old.
Spanning nearly 435 miles across the surface, the valley stream is named Nirgal Vallis and experts said it was shaped by flowing water and impacts
The valley, deemed one of the largest on Mars, sits south of the planet’s equator, which experts believe was ‘shaped by a mix of flowing water and impacts: events where rocks sped inwards from space to collide with the Martian surface,’ the Europe Space Agency (ESA) shared in a press release.
The images were captured by a spacecraft’s High Resolution Stereo Camera, which the ESA has employed to map the entire surface of Mars in full color and high resolution.
The area in the picture shows the western end of the river system, where it is slowly spreading out and dissipates.

Never read it. Not much of a reader.
But that’s a tantalizing piece from it.
Did the book include the same time frame as the movie?
I remember a military that looked maybe 1940s or 50s in the movie.
Are there any fish?
Interesting. Not sure I buy into it where Mars canals are concerned, but nature does many amazing things both on the micro and the macro scale.
"Yet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this earth with envious eyes -
and slowly and surely they drew their plans against us."
Anyone name the river yet—How about Issus? For those who know Barsoom.
And I checked elevations, it does run from uphill to downhill left to right on the image.
I believe the movie (and the radio broadcast) updated the book to contemporary times. The book deals with the menace using good cutting-edge late 19th century technology.
I guess they will announce petrified SUVs, cows and airliners soon.
It’s simply amazing. Rich detail of day-to-day British life set in 1905, written in 1897, the cultural and historic data (up to the flashes seen on Mars) can’t help but be accurate.
The story from the landing of the first Martian cylinder are plausible, the depicted reactions of the British are true to what a man on the street, and what government agencies would do.
The 1953 George Pal version is OK, but like most screen plays, not very true to the book.
The five movie versions (I have all five) of the tale released in 2005 are pale comparisons.
Perhaps an audio book would better fit your life? I listened to it while driving (several times!). Get an unabridged version. All the abridgements I’ve listened to simply left too much on the cutting room floor.
What you did there. I see it.
The part that made me shudder as a 10-year old (and still does!) was in the coal cellar when the probing tentacle touched the heel of his boot.
like a lava flow Positive, rather than a river bed negative.
A trick of light and shadow. the image was illuminated from the bottom, a very unnatural way to view things. Rotate it 180° and the illusory ridge turns into a valley.
Man, now you have me going with that. I am going to have to go deeper to find out.
Regardless, how did the water get there, and where is it?
Assuming it was water.
Thus there is feathering at the smaller branches upstream on dry beds.
These beds, and their tribs have rounded ends, more like a flow going in the opposite direction, then cooling off, similar to ice or lava flows on this planet.
At least with the depiction above.
I just went and zoomed in and it is indeed a valley. Everything matches the impact craters next to it. If you look in the lighter image strip areas in the image I posted above you can see this.
In the image I posted above, the elevation does go downhill from left to right. Not right to left. I checked it while I was there capturing it just to make sure.
