Take an Ultra-Detailed Tour of the Moon With This NASA Video

A new video will give you a tour of the Moon as you've never seen it, courtesy of NASA's Lunar Reconnaissance Orbiter. The 4K-resolution visualization posted by NASA's Goddard Space Flight Center, spotted over at CBS, was created using image data collected by the spacecraft since it began orbiting the Moon in 2009.

NASA narrates a guided tour that explores features like the Moon's South Pole, the famous Tycho Crater, the Aristarchus Plateau, and the Apollo 17 landing site in the Taurus-Littrow Valley.

The high resolution of the imagery allows you to clearly see things like the mysterious 328-foot-wide boulder on top of Tycho Crater's central peak and the Apollo 17 lunar lander and rover that still sit on the surface of the Moon.

The video explains the importance of the sites pictured and what the LRO data can tell us about the Moon's structure and characteristics, like how studying shadows on the Moon's North Pole can help us scope out sites for future solar power generators. Gravity measurements from the Orientale Basin may reveal the structure of the lunar crust there, and temperature readings and reflectance could alert us to potential water ice at the South Pole.

Take your own personal tour of the Moon in the video below.

Astronomers Discover 12 New Moons Around Jupiter

As the largest planet with the largest moon in our solar system, Jupiter is a body of record-setting proportions. The fifth planet from the Sun also boasts the most moons—and scientists just raised the count to 79.

A team of astronomers led by Scott S. Sheppard of the Carnegie Institute for Science confirmed the existence of 12 additional moons of Jupiter, 11 of which are “normal” outer moons, according to a statement from the institute. The outlier is being called an “oddball” for its bizarre orbit and diminutive size, which is about six-tenths of a mile in diameter.

The moons were first observed in the spring of 2017 while scientists looked for theoretical planet beyond Pluto, but several additional observations were needed to confirm that the celestial bodies were in fact orbiting around Jupiter. That process took a year.

“Jupiter just happened to be in the sky near the search fields where we were looking for extremely distant solar system objects, so we were serendipitously able to look for new moons around Jupiter while at the same time looking for planets at the fringes of our solar system,” Sheppard said in a statement.

Nine of the "normal" moons take about two years to orbit Jupiter in retrograde, or counter to the direction in which Jupiter spins. Scientists believe these moons are what’s left of three larger parent bodies that splintered in collisions with asteroids, comets, or other objects. The two other "normal" moons orbit in the prograde (same direction as Jupiter) and take less than a year to travel around the planet. They’re also thought to be chunks of a once-larger moon.

The oddball, on the other hand, is “more distant and more inclined” than the prograde moons. Although it orbits in prograde, it crosses the orbits of the retrograde moons, which could lead to some head-on collisions. The mass is believed to be Jupiter’s smallest moon, and scientists have suggested naming it Valetudo after the Roman goddess of health and hygiene, who happens to be the great-granddaughter of the god Jupiter.

Look Closely—Every Point of Light in This Image Is a Galaxy

Even if you stare closely at this seemingly grainy image, you might not be able to tell there’s anything to it besides visual noise. But it's not static—it's a sliver of the distant universe, and every little pinprick of light is a galaxy.

As Gizmodo reports, the image was produced by the European Space Agency’s Herschel Space Observatory, a space-based infrared telescope that was launched into orbit in 2009 and was decommissioned in 2013. Created by Herschel’s Spectral and Photometric Imaging Receiver (SPIRE) and Photodetector Array Camera and Spectrometer (PACS), it looks out from our galaxy toward the North Galactic Pole, a point that lies perpendicular to the Milky Way's spiral near the constellation Coma Berenices.

Each point of light comes from the heat of dust grains between different stars in a galaxy. These areas of dust gave off this radiation billions of years before reaching Herschel. Around 1000 of those pins of light belong to galaxies in the Coma Cluster (named for Coma Berenices), one of the densest clusters of galaxies in the known universe.

The longer you look at it, the smaller you’ll feel.
