A New Moon is Discovered in the Solar System

Turns out there is something new under the Sun, at least to us; on Tuesday, April 26 scientists announced the discovery of a new moon in the Solar System—but it’s not around Earth, or Jupiter, or Saturn, or any of the planets that you’ve long been familiar with. This new moon is orbiting a distant world even…

Ride Shotgun With John Young During His Apollo 16 Grand Prix

Take a ride across the Moon with Apollo 16 commander John Young in this video, a stabilized version of NASA 16mm film footage captured during the first EVA of the mission on April 21, 1972. In what’s called the “lunar Grand Prix” Young pilots the Lunar Roving Vehicle, or LRV, across the dusty terrain of the…

Europa’s Icy Crust May Be Warmer Than We Thought

All the worlds may be ours except Europa but that only makes the ice-covered moon of Jupiter all the more intriguing. Beneath Europa’s thin crust of ice lies a tantalizing global ocean of liquid water somewhere in the neighborhood of 100 kilometers deep—which adds up to more liquid water than is on the entire surface of the Earth. Liquid…

Planet Nine May Have Once Been an Exoplanet

It hasn’t even been found yet (they’re still working on that) but the recently-announced Planet Nine is already spurring discussion amongst the world’s astronomers. One of the recent topics surrounding this alleged new planet is (again, besides where it’s hiding) how it formed and how it got into the incredibly distant orbit it’s thought to be…

New Analysis of Apollo Data Reveal the Moon is Hollow

New analysis of data acquired by seismometers placed on the Moon’s surface in the early 1970s and laser measurements taken during recent lunar meteor impact events appears to support an ongoing, if unpopular, hypothesis that our Moon is, in fact, hollow.

Pluto’s Frozen Lake Hints at a Warmer Past

Hockey fans take note: future visitors to Pluto may want to bring along their sticks and skates—the distant planet may harbor some pristine ice in the form of frozen ponds and lakes! (NASA might have to work on a lightweight, collapsible Zamboni first though.)

This is the Oldest Surviving Photo of the Moon

These days anyone with a cheap point-and-shoot camera or even a cell phone can snap a picture of the Moon (although I highly advise using at least an entry-level dSLR) but there was a time when that wasn’t the case. Go back to the late 1830s, when photography was in its infancy and methods for capturing light…

Ceres’ Bright Spot Looks Like a Giant Zit

After more than a dozen years of head-scratching we finally have our first really good look at the weird bright spot on Ceres, thanks to NASA’s Dawn spacecraft and its low-altitude mapping orbit (aka LAMO) around the dwarf planet. Appearing from 240 miles up as a dome covered in cracks and rising from the surrounding darker…

What If You Had a Black Hole in Your Pocket?

What would happen if you somehow had a coin-sized black hole to play with? (Come on, you know you’ve been wondering about this.) Well, besides the fact that you’d quickly be dead (spoiler alert) a lot of things would happen—to you, to the world around you and, depending on the kind of black hole, to…

Pencil This In: Mercury’s Surface is Darkened by Graphite

Monochromatic and covered in craters, Mercury may outwardly resemble our Moon but the similarities abruptly end there. Ever since the MESSENGER spacecraft entered orbit around Mercury in 2011, and indeed even since Mariner 10‘s flyby in 1974, peculiar “dark spots” observed on the planet’s surface have intrigued scientists as to their composition and origin. Now, thanks to high-resolution spectral…
