Can you see that tiny dot? 
  
 Want to feel insignificant? Look at this photograph taken by Mars rover Curiosity. See that tiny spot that looks like a star? In fact, it likely looks more like a speck of dust on your screen. Well, thatās not a star or dust, thatās a planet ā Planet Earth to be precise. 
  
 PHOTOS: Distant Earth: A History of āPale Blue Dotsā 
  
 Hereās an annotated view in case you need some help in finding it:

 On Jan. 31 (sol 529 of its mission), Curiosity looked toward the twilit horizon about 80 minutes after sunset and took a few shots with its Mastcam knowing that Earth would be in view. After a little processing, mission scientists were able to find the location of Earth. But thatās not all ā our moon was also visible. Itās faint, but itās there:

 Like the many āPale Blue Dotsā taken by a growing number of space missions, this shot embodies our feeling of solitude in the great vastness of space. To humanity, that tiny dot is everything that ever was and is. 
  
 āFrom this distant vantage point, the Earth might not seem of any particular interest. But for us, itās different. Consider again that dot. Thatās here. Thatās home. Thatās us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.ā 
  
 NEWS: Billion Pixel Photo of Mars Snapped by Curiosity 
  
 This quote was of course in reference to the original 1990 Voyager 1 āPale Blue Dotā photograph of Earth and beautifully described by Carl Sagan in his book āPale Blue Dot: A Vision of the Human Future in Space.ā At Saganās request, the Voyager probe looked back toward its point of origin, spotting the tiny speck of reflected light from our planet at a record-breaking 3.7 billion miles (6 billion kilometers or 40.5 AU) away. Other missions, such as NASAās Cassini Saturn mission and NASAās MESSENGER orbiter around Mercury, have gotten in on the act. 
  
 Now Curiosity has joined the exclusive ārobotic Earth-gazers clubā from the Martian surface approximately 93 million miles (150 million kilometers or 1 AU) distant. Curiosity isnāt the first Mars surface mission to image the Earth from Mars, however. That honor goes to NASAās Mars Exploration Rover Spirit that took an interplanetary snap in 2004, 63 sols after landing. 
  
 ANALYSIS: The Moment When Curiosity Breached a Mars Dune 
  
 This photo may make you feel insignificant, especially as Earth is barely a pixel wide, but it proves that, as a race, we are capable of profound things ā such as sending robotic emissaries throughout the solar system to observe the Earth from afar, ultimately helping us understand our place in the Cosmos.

 And when seen by NASA's Mars rover Curiosity spacecraft across the vast expanse of space, that pale, blue dot he described suddenly makes sense. It's home -- but just one tiny speck barely visible in the infinite reach of space. 
  
 One very important speck, that is: 
  
 “Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there -- on a mote of dust suspended in a sunbeam. 
  
 The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. From Carl Sagan's "Pale Blue Dot: A Vision of the Human Future in Space." 
  
 From the surface of the Red Planet, NASA's rover took a few minutes off from its science mission to gaze back at our planet, capturing a twinkling Earth spinning slowly in the sky. 
  
 The view of the twilight sky and Martian horizon shows Earth as the brightest point of light in the night sky -- the planet is a little left of center in the image, and just beneath it, almost invisible in the picture, our moon. 
  
 A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright evening stars, NASA said. 
  
 Not everyone was pleased with the view, however; a very sad Tweet from the parody Twitter account @SarcasticRover puts a different spin on the image: 
  
 I took a picture of the Earth last week and then I put "You are here" on it and laughed for an hour. Then I cried. http://t.co/QgkUqj4Lda — SarcasticRover (@SarcasticRover) February 6, 2014 
  
 In July 2013, NASA's Cassini craft took a similar image of Earth from over 900 million miles away, as the spacecraft spun around the planet. Researchers called it "the day the Earth smiled," because NASA asked Earthlings to smile and wave back at the spacecraft, knowing the exact moment the picture would be taken. 
  
 If you could somehow zoom in on that amazing picture, you'd see millions of smiling faces, as the planet paused to wave back to Saturn. 
  
 Researchers used the left eye camera of Curiosity's Mast Camera (Mastcam) to capture the new scene about 80 minutes after sunset on the 529th Martian day, or sol, of the rover's work on Mars -- Jan. 31, 2014. |||||
A:
The Mars rover Curiosity paused last week to take a photo of its home planet, and NASA points out that Earth is "shining brighter than any star in the Martian light." If you look carefully—one of the images provides help—you can pick out the moon just below it. Still, we're just a speck in the sky. Humbled? Try these reactions: Discovery: "This photo may make you feel insignificant, especially as Earth is barely a pixel wide, but it proves that, as a race, we are capable of profound things—such as sending robotic emissaries throughout the solar system to observe the Earth from afar, ultimately helping us understand our place in the Cosmos." Fox News: It quotes Carl Sagan, from his book Pale Blue Dot, in writing about a similar image taken by Voyager I: "Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives."
