This is Earth and the Moon from 40 Million Miles Away

That’s here; that’s home; that’s us—the two bright objects in this picture are Earth and the Moon, imaged by NASA’s OSIRIS-REx spacecraft on January 17, 2018 from a distance of 39.5 million miles (63.5 million km). This is about the distance between Earth and Mars at their closest points to each other (give or take…

Are Alien Bugs Crawling On The Outside Of The ISS?

Well this is interesting: an article on CNET by Eric Mack, based on a Nov. 27 report from the Russian news agency TASS, discusses findings by Russian cosmonaut Anton Shkaplerov that “living bacteria from outer space” were found within samples collected during spacewalks several years ago (Shkaplerov was a member of Expedition 42 in November 2014.) The samples…

If You Were Wondering What Earth Looks Like From Saturn, Here You Go

That’s here; that’s home; that’s us. The image above shows what Earth looked like to NASA’s Cassini spacecraft on April 13, 2017 as it flew past Saturn’s night-shadowed A and F rings. At the time the raw images were captured Saturn and Cassini were about 889.6 million miles (1.43 billion kilometers) from Earth. From that distance…

These Photos Taken from the Moon Show Lots and Lots of Stars

One of the favorite allegations by those who continue to be skeptical of the Apollo moon landings is that there are no stars visible in the photographs taken by the astronauts while they were “supposedly” on the Moon. Now while there’s a rather short but succinct list of why that’s the case (and feel free to review those…

After 15 Years NASA and DLR Prepare to Say Goodbye to GRACE

On March 17, 2002, a pair of satellites nicknamed “Tom” and “Jerry” launched aboard a Russian Rockot vehicle from the Plesetsk Cosmodrome in Russia. It was the start of the Gravity Recovery and Climate Experiment, aka GRACE, a partnership mission between NASA and the German space agency (DLR) to map Earth’s gravity field and how it…

Did Ancient Supernovas Change Earth’s Climate?

Supernovas are some of the most powerful and energetic events in the entire Universe. When a dying star explodes you wouldn’t want to be anywhere nearby—fresh elements are nice and all, but the energy and radiation from a supernova would roast any planets within tens if not hundreds of light-years in all directions. Luckily for us…

Clementine: Lost and Gone Forever, But Never Forgotten!

One of my all-time favorite space images is this little gem from the Clementine mission to the Moon, launched January 25, 1994. It features a view from beyond the far side of the Moon, illuminated by reflected light off the Earth off frame to the left. The Moon is blocking the disc of the Sun with the glow…

Meteors May Make Your Hair Hiss

Have you ever gone outside on a cold, clear night to watch a meteor shower and witness a super-bright fireball racing across the sky so brilliantly that you could swear you could hear it? Turns out the sizzling noise might not have been all in your head after all…but rather on it. (And here’s science to prove it.)

Voyager 1’s Famous Long-Distance Valentine

If you’re in love with space then you’ll fall head over heels for this: it’s a picture of Earth taken from the Voyager 1 spacecraft after it passed the orbit of Pluto back in 1990—on Valentine’s Day, no less. That image of our planet from almost 4 billion miles away inspired Carl Sagan to write his famous…

Earth: Enhanced! NASA’s EPIC Global Views Get an Online Image Boost

From a vantage point of nearly one million miles away NASA’s EPIC camera aboard NOAA’s DSCOVR satellite captures an image of the entire Earth every 1-2 hours as it rotates. For the last year and a half or so these pictures have been uploaded on the EPIC website for public viewing and use as they originally look to…
