This is Our Most Detailed Image of the Sun’s “Surface”

The first image from the National Solar Observatory’s Daniel K. Inouye Solar Telescope shows the “surface” (i.e., the photosphere) of our Sun in the highest resolution ever obtained, revealing structures as small as 30 kilometers (18.6 miles) wide squeezed between cells of convective activity—many of them considerably larger than the state of Texas!

A Naked Titan Revealed by 13 Years of Cassini Data

Saturn’s largest moon Titan boasts the distinction of being the only moon in the solar system to have a thick atmosphere…so thick, in fact, that its surface is perpetually hidden from our view—but not from the view of the Cassini spacecraft’s infrared cameras! Cassini, now over ten months gone after its Sept. 2017 plunge into…

ESA Grabs Glimpses of Mars’ Groovy Moon

This animation is comprised of three images acquired by ESA’s Mars Express spacecraft on Sept. 12, 2017 with its High Resolution Stereo Camera (HRSC). It shows parts of the grooved and pitted surface of Phobos, the larger of Mars’ two natural satellites. The original images were captured in greyscale; I added color based on other…

Antares is a Bug-Eyed Monster 700 Times Bigger Than Our Sun

From a “mere” 93 million miles away we’re able to view the surface of our home star the Sun very well with telescopes on Earth and in space…you can even observe large sunspots with your unaided eye (with proper protection, of course.) But the surface details of other stars tens, hundreds, or thousands of light-years…

These New Pictures of Pluto Are Almost Impossibly Awesome

Hold on to your seats, hats, socks, etc… these newly-received and -released images of Pluto from the New Horizons spacecraft are, in a word, icantbelievewhatimseeingisreal! But they are real, and that’s what’s so great! Obviously you’re already looking at one of them above: it’s a view of Pluto captured after New Horizons had already made its closest…

Pluto: Prelude to a Flyby

This is ‪‎Pluto‬, imaged by New Horizons’ LORRI camera on July 12. It’s (once again) the best view yet, captured from a distance of 2.5 million km / 1.5 million miles. Check out all that geology – craters, depressions, chaos terrain of some sort… at no time in human history has anyone ever seen this world in…

Is That an Ice Cap? New Horizons Detects First Details on Pluto

Taken from a distance of about 69 to 64 million miles – just about the distance between the Sun and Venus – the images that make up this animation were captured by the LORRI imaging instrument aboard the New Horizons spacecraft and show its first detection of surface features on Pluto, including what may be the bright reflection of…

This Is the First Color Image from the Surface of Venus

The surface of Venus is definitely no easy place to which to send a spacecraft. Crushing atmospheric pressures, powerful high-altitude winds amid caustic clouds of sulfuric acid, and temperatures that can soar above 880ºF (475ºC) make the next planet in a no-man’s-land for robotic spacecraft. But those challenges didn’t stop the Soviet space program from successfully putting several…

Latest Images of Ceres Show Its Bright Spot Is Actually Twins!

Here’s your weekly Ceres update! The dwarf planet’s features are coming into better and better focus for the approaching Dawn spacecraft, which will be captured by Ceres’ gravity on March 6. The image above is yet another “best-ever” of Ceres (as will be each one we see now), captured on Feb. 19, 2015, from a distance of…
