Why are the images sent from Mars in black and white rather than color?

The reason that peripheral vision is in color is because of the cone cells inside the eyes. Cone cells are generally present in humans but some males become color blind...

Stellar parallax on Earth involves measuring the position of a star and then measuring the position again 6 months, or 183 days, later when is at the opposite side of...

Sun spots are darker than the surrounding photosphere because they are cooler. Sun spots are caused by strong magnetic fields. These magnetic fields locally slow the convection process which is...

You radio wave should travel at the speed of light in vacuum $c=3xx10^8m/s$ so basically it would take (velocity=distance/time rearranged): $t=d/c=(8.2xx10^10)/(3xx10^8)=273s$ to reach Mars.

Because venus has an extremely hot surface it is very hard to colonise and travel around. Mars on the other hand is a way better candidate. It's closer, colder, more...

How are the Hubble images in the image archive created? Like any modern telescope, Hubble captures images on a digital device that transforms photons into electrons; and the latter carry...

Even if a man has normal colour vision, he may be a carrier for green-red colour blindness. And if his partner is a carrier or suffers from the disease, then...

As we know, the leaves are receiving sunlight and converting light into starch, and the reason why most leaves look green is that they have chlorophyll. Chlorophyll can absorb...
