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…

Apollo 10’s “Outer-Space-Type Music” Explained

There’s been some buzz recently (no pun intended, Mr. Aldrin) concerning supposed “space music” heard by Apollo 10 astronauts while they were traveling around the far side of the Moon in May of 1969. This is in no small part due to the season three opener of NASA’s Unexplained Files* on the Science Channel, which aired on…

It’s Been 50 Years Since We First Got Pictures From the Moon

What a difference half a century makes! This week marks 50 years since the Soviet Luna 9 spacecraft made humanity’s first-ever soft landing on the surface of the Moon. Launched from Baikonur on Jan. 31, 1966, the Luna 9 lander touched down within Oceanus Procellarum at 18:44:52 UTC on Feb. 3. Over the following three days Luna 9 sent us our first views of…

NASA’s First Fallen: Remembering the Tragedy of Apollo 1

This is a reprint of a post from 2013, updated for the 2016 date. Today marks the 49th anniversary of one of the worst tragedies to befall NASA and human spaceflight: the fire that broke out in the Apollo 204 (later renamed Apollo 1) command module during a test exercise at Kennedy Space Center in…

Is This New Picture of Earth From the Moon for Real? Yes, Yes It Is.

Today NASA released an amazing image of Earth taken from the Moon — specifically from lunar orbit by NASA’s Lunar Reconnaissance Orbiter, which has been studying our Moon since the summer of 2009. In it our planet appears as an incredibly bright blue globe with swashes of white clouds and Africa and northeastern South America clearly visible…

Long-Lost Impact Site Found From Apollo 16 Rocket Stage

In April of 1972 the penultimate Apollo mission sent NASA astronauts John Young and Charles Duke to the surface of the Moon, with Ken Mattingly piloting the command module Casper in lunar orbit. After launch on April 16, the Apollo 16 craft and crew completed two orbits of Earth before burning the J-2 engine of the Saturn…

Why Do People Say the Moon is Made of Green Cheese?

So this isn’t about a scientific discovery by any means, but I did do a little bit of online research to discern the origin of the old expression that the Moon is “made of green cheese.” We’ve all heard it, and though I’m pretty sure that nobody has ever actually taken it as a fact (although when it…

What Would it Take to Knock the Moon Out of Orbit?

Whenever there’s news of an asteroid expected to pass closely by Earth (like this one did on Halloween 2015) at least one person will ask “what if it hit the Moon?” — as if that’s a scenario that somehow all of the astronomers around the world who specialize in near-Earth objects failed to take into…

Tons of Unprocessed Apollo Mission Photos Are Now Just a Click Away

This has made quite a splash across the internet over the past several weeks, and for good reason: the Project Apollo Archive is now on Flickr, giving anyone and everyone point-and-click access to some of the best scans of original Apollo mission photographs that have been made to date. Really, this is something you can get…

Supermoon Eclipse 2015

Last night a large part of the world’s population was treated to a relatively rare variety of a not-so-rare night sky spectacle: a total lunar eclipse that happened to coincide with the closest perigee Moon (aka “supermoon”) of the year. The last time these scenarios lined up this way was in 1982, and it won’t occur…

Get Ready For The First Total Supermoon Eclipse in 33 Years

It’s coming — on September 27 there will be a total lunar eclipse, the entirety of which will be visible across much of the western hemisphere! During total lunar eclipses the Moon passes through the shadow of Earth cast by the Sun, and is colored by dusky blue, purple, and crimson light as its normally…
