A View from Mars: Earth, Jupiter and Venus

From the surface of the red planet Mars, recent observations provide a view of the Earth, Jupiter and Venus (top down) in the sky. The moon may sometimes be seen orbiting the Earth in clear Martain skies. In the not-so-distant future, a human trek to the moon, Mars, or even the moons of Jupiter, will be a bold experience much like an 18th century trek from America to Europe or Asia. Pack adequate supplies for the extended trip!

The photo needs proper color correction as has been done to many photos of Mars. The "red" planet is actually not that "red" and the skies are silver blue.

No.

Due to high dust content in the atmosphere, stars are not visible from the martian surface.

Most likely computer-generated, not a real pic. It seems unlikely to me that you'd be able to see 3 planets but not see any stars.

This picture is a fake as can be seen from the "NE" tag in the bottom left corner, which comes from a 'planetarium software' such as Stellarium.

Darvedd,

There appears to be at least two stars ... on in the upper right corner of the image and another about the third of the way above the horizon on the right side.

I live in the city where it is common to only see the light from Saturn Jupiter and Mars while all of the stars are blocked from light pollution. I don't see why it wouldn't be the same as on mars.

Ellen said...

yep, nice sentiment, but this IS a planetarium picture.. so it is fake. Read: http://blogs.discovermagazine.com/badastronomy/2012/08/10/an-unreal-mars-skyline/
and see the NE in the corner etc.
There ARE real pics from Mars... see next comment. Why do we need fake when the real is there. Something like SciFi movies have sound in space because it's more fun? ??? Let's keep it with reality, that is fantastic and wonderful enough! -- Ellen from Ontario Canada

Ellen said...

Now THIS one.. IS real... REAL okay, so a real picture from Mars of our.. OUR planet, with us hidden in those pixels. REAL...

Have fun, and appreciate reality.

And where, pray tell, would all that light pollution on Mars be coming from? There sure are a lot of cities on Mars, ain't there now.

Varun said...

Yea, cuz there's so much light pollution on Mars, LOL

The image is clearly captured at sunset, so as on Earth it's entirely expected that only the brightest (closest) celestial objects would be visible to the eye or a standard optical camera.

You can see this on earth most nights if looking at the right portion of the sky. You will have a view of planets and the ISS well before the star filed becomes visible.

Sorry - not real. Bummer, I know. http://blogs.discovermagazine.com/badastronomy/2012/08/10/an-unreal-mars-skyline/

The problem with this photo is the order in which the planets occur. Vague possibility that Earth and Venus may be seen in the same photo but definitely not with Venus occuring larger than Earth but common sense indicates that you would not see Jupiter in the same photo unless it was time-lapse (also unlikely) Jupiter is farther out and would not be visible in the dawn or dusk periods. Far too much wrong for this to be a real photo.

Actually, from the top down, it is Earth, Venus, and Jupiter. If you have the program Celestia, you can go to Mars and see the configuration yourself.

Walk outside right before the sun comes up and all you'll see in the sky is Venus and Jupiter right on top of eachother until well after all the other stars are all invisible. I look at them often. However, if Earth were that bright and this were real, wouldn't the moon also be visible at this time? I imagine that varies greatly depending on the distance between Earth and Mars, but if we could see Mercury from Earth sometimes, we could see the moon from Mars, if viewing conditions were the same.

Actually if you know anything about orbital mechanics it is possible for Venus to appear larger and brighter than earth is the earth is on the opposite side of the sun from mars' perspective and venus is on the near side (from the same perspective. Jupiter would be in the picture as well as other orbital bodies for the same reason. As far as light pollution it is either a sunset or a sunrise picture just as we see venus and jupiter at dawn or dusk. The color balance is probably enhanced to give us the martian nuances cause its what we have come to know but that does not make it fake.

DJ Steevo said...

Actually if you know anything about orbital mechanics it is very possible for that to be the correct order and as far as Venus appearing larger (brighter) this is also feasible if earth (from mars perspective) is on the opposite side of the sun with Venus perpendicular on the plane of the ecliptic. In that case Venus would be closer to mars than earth and vis a vie "larger". Same with Jupiter of course. As for earlier comments as a photographer I can say that yes the color balance was probably enhanced to give a more martianesque appearance but that is only to make it familiar to the science challenged masses. However enhancing a photo does not make the subject fake or can we just go ahead and assume that Gisele Bundchen doesn't exist either....
