Turns out, Mars isn’t the vibrant red we often picture—it’s more of a rusty, muted hue. A physicist breaks it down: the planet’s reddish tint comes from iron oxide (basically cosmic rust) in its rocks, which stands out against the darker tones of other planets when viewed from a distance.

Turns out, Mars isn’t quite as red as it seems—at least not all the time. A physicist breaks down why the planet’s famous rusty hue can look different depending on how you’re observing it, whether through a telescope, a rover’s camera, or even the naked eye. The color shifts come down to dust, light, and a sprinkle of cosmic illusion.

Editor’s Note: Mars has always been this mysterious red dot in the sky, but this piece peels back the curtain on why its color isn’t as straightforward as we think. It’s a cool reminder that even the simplest things—like a planet’s color—can have layers of science behind them. Plus, it’s a neat example of how perspective (and technology) shapes what we “know” about space.

Right now, Mars is putting on a dazzling show in the night sky, snuggling up close to Regulus—one of the brightest stars out there, nicknamed the "Heart of the Lion." A stunning photo captures this rare cosmic meetup, and astronomers are calling it "mind-blowing."

Editor’s Note: Skywatchers and space enthusiasts, this is your moment. Conjunctions like this don’t happen every day, and seeing two bright celestial objects side by side is a treat. It’s a reminder of how dynamic and beautiful our universe is—no telescope required, just look up!

This week, skywatchers are in for a treat as Mars joins the Spring Triangle—a bright trio of stars (Arcturus, Spica, and Regulus) that dominate the spring and summer night sky. You’ll be able to spot the red planet nestled among these stars until mid-September, adding an extra sparkle to an already stunning celestial lineup. The article gives tips on when and where to look for this rare alignment.
