The HiRise Mars orbiter, has captured stunning images of spruce-like trees on the surface of the red planet.





While in the above photo, they certainly look like trees, here's the larger image showing greater detail.

Mars 'Tree' PHOTO: NASA HiRISE Camera Shoots Picture Of Sand Dunes

So much for the claims by people who believe gigantic trees are growing on Mars.

Some people believe what they choose; despite facts. Examples...the Moon landings were a hoax...LOL.

The up-close shots even look like trees....but then there are all the waves in the pic....so it is hard to tell. All the pics from Mars are fascinating. It is either a world that ended or a world that started but never finished maturing. Hard to tell.

What we're seeing in the photo are huge sand dunes, carbon dioxide frost and dark patches of basaltic sand, some of which is cascading down the slopes of the dunes and leaving those dark streaks. About midway in the photo you can see a cloud of dust billowing from an avalanche. But you're right, they do resemble trees, especially in the small photo. It's an interesting optical illusion.

I'd say it's become a pretty cold, dead planet with a very weak atmosphere and very weak and odd magnetic fields. It's a desert planet. But it's still active with winds and plenty of dust devils, seasonal ice caps, shifting sand dunes, dust storms that can nearly cover the entire planet, and other features.

It's pretty safe to say there are no gigantic trees or plants, no advanced native life forms or civilizations either now or in its past. It's still possible there might be some kind of microbial life forms, but they'd most likely be underground. The surface is far too hostile for life as we know it because of the intense exposure to cosmic radiation. It'd be amazing to discover such life on Mars because that would confirm the existence of life beyond the Earth.

In any case, the photographic view is still fascinating to see. There's a lot more waiting to be discovered on Mars.
