The Pleiades are an open cluster easily visible to the naked eye. The cluster is dominated by several hot, luminous and massive stars.
The blue nebulosity surrounding the brightest stars are due to blue light from the stars scattering off of dust grains in the interstellar gas between us and the stars. The cluster is also known as the ‘Seven Sisters’. And in Japan it is called Subaru.
The image was generated with observations in the B (blue), V (green), and I (red) filters. In this image, North is right, East is up.
My favorite constellation. It’s so cute! It looks like a mini little dipper in the sky
Because Earth is closer to the sun, it travels faster, completing a circuit in 365 days. By the time Mars has completed one circuit, Earth has a lot of catching up to do to get to a point between the Red Planet and the sun. As Johannes Kepler discovered in the 16th century, the planets follow slightly elliptical paths around the sun, sometimes closer to the Sun (perihelion), sometimes farther away (aphelion). Six days later, both planets will have moved a little along their orbits, but, because of the eccentricity of its orbit, Mars will be slightly closer to Earth than it was before.
Just so you know, a lot of images of Mars which you’ll see have been manipulated. A lot of them have boosted contrast and saturation. So if you’ve ever wondered – images like this one are what Mars actually looks like.
Why does this not have more notes?!?
YOU ARE LITERALLY LOOKING THROUGH THE EYES OF A ROBOT ON ANOTHER FUCKING PLANET
If you don’t think that’s the tightest shit, you can get out of my face.
