Rosetta’s Perihelion-Bound Comet Fires a Fountain Into Space

On July 29, with ESA’s Rosetta spacecraft in orbital tow, the 2.5-mile (4-kilometer) -long Comet 67P/Churyumov-Gerasimenko fired its brightest jet yet since Rosetta’s arrival just over a full year ago, on Aug. 6, 2014. Most of the images of 67P showing jets and outgassing activity released over the past few months have been edited to…

Today in 1966: Lunar Orbiter I Launched to Map our Moon

On August 10, 1966, NASA’s Lunar Orbiter I launched from Cape Canaveral aboard an Atlas-Agena D rocket, the flagship spacecraft of a program designed to map the Moon and investigate intended landing sites for the planned Apollo landings, including helping determine the risks from micrometeorite and radiation exposure. Over the course of the next twelve months and five…

No This Is Not an Alien Cave Crab on Mars

I’m in a debunking mood today, probably brought on by the seasonal “double Moon hoax” that raises its oh-so-wrong head every August. (Read more on that nonsense here.) So here’s one more thing to say “NO” to: giant alien cave crabs on Mars. Apparently there’d been some buzz recently in the “space woo” circles online…

Mars Will NOT Be As Big As The Moon In The Night Sky

No, no, no…a thousand times NO: Mars will not become a “second Moon” in the sky on August 27. It won’t this year, it didn’t last year, and it didn’t in the past dozen years since this silly yet strangely perennial cyber-legend (yes I just used the prefix “cyber”) first started circulating on teh interwebz. I don’t know…

Dawn Finds Similarities Between Ceres and Saturn’s Moons

Around 600 miles wide, covered in craters and cliffs, a composition of rock and water ice… these are descriptions of both several of Saturn’s moons and the dwarf planet Ceres, based on recent observations by NASA’s Dawn spacecraft. New topographical maps show that, in terms of surface features anyway, Ceres shares similarities with Saturn’s icy…

Behold the Hidden Colors of Pluto

This newly-released picture of Pluto isn’t quite what our eyes would perceive… but then our eyes aren’t high-tech scientific imaging sensors like the ones aboard New Horizons! An enhanced-color image made from data acquired by the spacecraft’s LORRI and Ralph cameras on July 13, 2015, this view of Pluto shows the many variations in surface compositions…

NASA Delivers a Brand-New Blue Marble Pic

It’s over halfway through 2015 and perhaps it’s high time for an all-new, updated, knock-your-socks-off “blue marble” photo of our beautiful planet Earth. And so earlier this week NASA delivered just that, courtesy of the high-definition EPIC camera (yes, that’s a real acronym) aboard the DSCOVR spacecraft positioned nearly a million miles away toward the Sun. The…

Another Mountain Range Discovered on Pluto

A new image from New Horizons has emerged, showing a new, smaller mountain range on the southwestern border of Pluto’s “heart” region. The image was captured during the July 14 flyby, during which time the spacecraft passed less than 8,000 miles from the planet’s surface.

This is Our Best Photo of Neil Armstrong on the Moon

Everyone knows that Apollo 11 commander Neil A. Armstrong was the first human to set foot on the Moon (and if you didn’t know, that occurred on July 20, 1969 – yes, it really happened). It was a momentous, history-making event that many (like myself) consider one of the most impressive achievements of humankind. But oddly…

Here’s What We Learned About Pluto Today

Three days after New Horizons‘ flight through the Pluto system and the data is coming in fast and furious (albeit quite highly compressed!), giving scientists a virtual “toy box” of new findings to make about these distant worlds’ exotic nature. On Wednesday we got our first looks at Pluto’s 11,000-foot-high mountains, now informally named Norgay…

Incredible 3D Rendering of Pluto’s Icy Alps

It’s only been a day since we got our first glimpse of Pluto’s mountainous terrain from New Horizons but there’s already a 3D video, created by Mattias Malmer. Of course it’s not comprehensively accurate imagery of the region, since there was only that one perspective image to work from, but it gives a fascinating look…
