Don’t Slip And Fall Here

Orbiting from above, space probes have located openings to a vaster underground on both the moon, and above, Mars. This scene (By NASA, JPL, U. Arizona – https://science.nasa.gov/download/file/fid/89311, Public Domain, https://commons.wikimedia.org/w/index.php?curid=87679776) is to be found on the slopes of one … Continue reading

All Eyes On Jupiter

Literally. Amateur astronomers all over the world, most all the time, it seems. Citizen (full-in-the-blank). Dislike that term. Citizen Journalist. Citizen Researcher. Citizen Kane. Citizen Mind-Your-Own-Business. I don’t mind calling myself an amateur astronomer. Or at least I did before … Continue reading

Vatican Observatory In Silver

It’s not exactly a coin, as it has no denomination. (But how else could I categorize this piece, above?) I was struck by this medal from the wiki summary on the Vatican Observatory. Image credit: By Rc 13 – Own … Continue reading

A Snake, Handled

I think reptiles–snakes in particular–get a bad rap. Or is it rep? Amphibians are slimy, but reptiles are warm and dry. Human beings have a thing against things that are different. Two legs good, no legs bad–stuff like that. And … Continue reading

USPS: Apollo 8

The US Postal Service followed up its Gemini stamp a few years later with Apollo 8’s “giant leap.” Neil Armstrong might have referenced humankind’s leap when he stepped on the moon, but truth be told, the first lunar orbit mission … Continue reading

USPS: Gemini

After Project Mercury and before the Apollo missions, NASA needed to solve problems and practice for what they would need to do for successful flights to the moon. Thus the effort named Gemini moved things forward with two-person crews. What … Continue reading

Crescent Moon and Venus

Before I put the car in gear to drive home last night, I texted the young miss to go out and catch the western sky. It was just after sunset. Much more impressive in person. Tonight, the planet will be … Continue reading

USPS: Project Mercury

When I was doing a little research on USPS and those sun science stamps the other day, I ran across this story from the Smithsonian National Postal Museum. Intriguing because it was my favorite stamp as a young boy. That … Continue reading

My Favorite Mission

Fifty years ago today, my favorite space mission left lunar orbit. It was a perfect alignment of summer vacation (therefore no interference going to school), the first serious scientific moon landing, and an early morning tv slot with Walter Cronkite. … Continue reading

USPS: Sun Science

My wife came home with this block from a trip to the post office. Since I gave the young miss the last of my T-Rex stamps the other day, we needed more. I confess I’ve never been a real stamp … Continue reading

On My Bookshelf: Women In Astronomy

Books by women astronomers haven’t exactly been on a bookshelf in my home–I’ve been reading them on my phone. It’s not a withdrawal from a pandemic world as much as the delightfully wide access my e-card gives me to libraries … Continue reading

Getting the Hand of Paint 3D

I confess I haven’t liked paint 3D for years. Now, maybe that’s different. I think of this as something a super-Earth might look like. Not super-hot, but more temperate. No life, but a lot of rock and a little water.

Near Ganymede

When NASA announced the Jupiter orbiter mission, I wondered if any part of it was going to be devoted to the moons. Monday’s flyby of Ganymede was a surprise to me. Does it look different from Earth’s moon? image credit: … Continue reading

Music In The Heavens

In pop culture, the star Vega is the source of the extra-terrestrial transmission that ultimately sends actor Jodie Foster on her wormhole journey to first contact. Why the aliens or author Carl Sagan would choose that star, who knows? It’s … Continue reading
