Latest images of Pluto’s flowing ice

View larger. | New Horizons spacecraft using the LORRI (LOng Range Reconnaissance Imager) camera. Image showing a large area near Pluto's sunset terminator, reveals how frozen nitrogen has flowed out from the plains into old, more cratered terrain. The nitrogen ice has flowed like normal water ice does on Earth, even in Earth's coldest places in Greenland and Antarctica. This surface is so cold, it has actual Nitrogen Ice glaciers. On Pluto however, water ice is as hard as solid rock and would not flow at those temperatures, but nitrogen ice does flow over time at the average surface temperatures on Pluto of minus 232 Celsius / minus 386 Fahrenheit or 41 Kelvin.

The images from New Horizons’ July 14 sweep past Pluto continue to come in. Among the recent discoveries: flowing nitrogen ice on Pluto! These exotic ices flow across Pluto’s at one edge of its bright heart-shaped area. Scientists had hoped to find signs of an active surface on Pluto, but, still, they were wowed by evidence of flowing ice.

Here’s something no one on Earth has ever seen before. NASA released this new image today (July 24, 2015). It’s the night side of Pluto with the hazy atmosphere scattering light from a distant sun.

Good news! More sharks!

White shark populations are growing. Here’s why that’s good news.

More ice mountains in Pluto’s heart

A second range of ice mountains has been discovered on Pluto.  Image via New Horizons spacecraft as it passed near on July 14, 2015.

A second range of ice mountains has been discovered on Pluto. Is that sunglint on the mountainsides? Image via New Horizons spacecraft as it passed near on July 14, 2015.

Here’s a new image just released of a second range of ice mountains on Pluto. The New Horizons spacecraft using the LORRI (LOng Range Reconnaissance Imager) camera captured this image when it swept closest on July 14, 2015. There are images coming shortly that will be about four times sharper than this one!

Pluto has five known moons, and it’s a bit surprising that New Horizons hasn’t found any new ones yet. Newly released images show small moons Nix and Hydra.

Philae comet lander falls silent

The Rosetta mission team is hoping that a software patch will help re-establish reliable contact with the little Philae lander, lodged somewhere on the comet’s surface.

If there’s really intelligent life out there, why haven’t they contacted us yet? Here are some possibilities.

Video: Moon hoax not

SG Collins explains why the Apollo moon landings on the moon in the late 1960s and early ’70s could not have been faked.

No double moon in 2015, or ever

This image is circulating on Facebook, with the claim that Mars will appear as big and bright as a full moon on August 27, 2013.  It's a hoax.  Don't believe it.  Mars never appears as large as a full moon in Earth's sky.

This image sometimes circulates on Facebook, with the claim that Mars will appear as big and bright as a full moon on August 27, 2014. It’s a hoax. Don’t believe it. Mars never appears as large as a full moon in Earth’s sky.

The famous double moon hoax appears to be gearing up again. We hear that the word spread on Facebook in July, 2015 that there would be a double moon. Will this hoax ever die? It’s now 12 years old. Still, clearly, not everyone knows it’s a hoax. Google searches have made this post the most popular on our site for the past week. An email must be circulating – somewhere, social media must be buzzing – with the suggestion that Mars will appear as large as a full moon in Earth’s sky. And that is just not true.
