Structure



More hints about the structure of our "local" universe has come to light: a vast empty area that seems to exert a repelling force on the Local Group. Toss in the Shapely Concentration and the Great Attractor and you have the makings of a Olaf Stapledon, E.E. "Doc" Smith or Peter F. Hamilton space opera!

Eclipse



During the last USA-wide total (and partial, depending on your location) solar eclipse, I remember reading articles about the next USA-wide total (and partial) solar eclipse in 2017. The far future!

How did I get here so fast?

Today's Astronomy Picture of the Day shows the path of totality (and historical cloud cover) for the 2017 solar eclipse.

Cosmic Marble



Hey, remember marbles? Remember trading them? Remember which ones were considered valuable? Nah, me neither. Today's Astronomy Picture of the Day is NGC 6543, The Cat's Eye Nebula.

Southern Wonders



Today's Astronomy Picture of the Day showcases one of the wonders found in the skies of the southern hemisphere: N159, in the Large Magellanic Cloud (one of the satellite galaxies to our own Milky Way).

More Like Grand Slam Finale



Today's Astronomy Picture of the Day shows the final stages of the Cassini Orbiter's Grand Tour at Saturn. The initial Grand Tour was extended several times into the Extended Cruise and looking at those final orbits: stay seated, as it's going to be scary.

Gaming the Sky



Today's Astronomy Picture of the Day shows the Winter Hexagon over the skies of Maula Reservoir. "Mouseover" the image (in the link) for a constellation guide.

Keeper of the Gap



Today's Astronomy Picture of the Day shows Saturn's tiny shepherd moon Daphnis as imaged by the hard-working Cassini orbiter. As the mission winds down, NASA and JPL are taking a few chances.

Buckle up for the ride.

Touching History



The last of the Apollo astronauts to walk on the Moon (hopefully, not the last person ever) has passed away.



Dark Planet



Today's Astronomy Picture of the Day shows the night skies over the Earth...from over the Earth. "Mouseover" the image (in the link) of the International Space Station to get a guide to what you are seeing.

Synchronization

Today's Astronomy Picture of the Day is a short video showing satellites in geosynchronous orbit moving through the constellation of Orion.

Close to Tears...



Was Clarke disappointed with the film of 2001: A Space Odyssey? This recollection probably (well, yes definitely) should be taken with some grains of salt. We no longer can ask Kubrick or Clarke for their recollections, but this contradicts the thousands of words written by them, or others involved with the production, or covering the production.


Update: A different posting of the same article throws a different light in emphasis.

World-Builders



Science Fiction and Fantasy author David Weber talks about the worldbuilding work of several authors. Some great stuff here (like Barbara Hambly).

Stardust Molecules



Today's Astronomy Picture of the Day brings us NGC 1333 and associated nebula. Stars, dust and complex molecules combine to bring a thing of wonder.

Into the Deeps



A look at our deep-space efforts.

Lift



A chart showing current (and a few proposed) lift vehicles.

Classic



Cover art for a 1966 Revell model of Gemini IV and a spacewalking Ed White. That was a great kit!

COINage



An interesting look at a game series that has caught my eye: The COIN series from GMT Games.

(The image above is more than COIN, but you get an idea of where my buying habits have been the past two years!)

Dusty Edges



Today's Astronomy Picture of the Day shows NGC 891 in the constellation of Andromeda (home of Messier 31). Seen edge-on, the more familiar spiral shape you see in Messier 31 is changed to a view of the stars and obscuring dust clouds embedded in the spiral.

Insert Obligatory Star Wars Reference Here



Today's Astronomy Picture of the Day comes courtesy of the long-running Cassini orbiter, now in the final stages of the mission. Saturn's moon Mimas displays crater Herschel with a very visible large central peak. Death Star, anyone?

Downtown Mars



And a busy day on Mars as well, also thanks to Robert McCall.

Rendezvous

Depot



An orbital fuel depot (artist uncredited, alas).

Squaring the Circle



Today's Astronomy Picture of the Day shows IC 4406, a planetary nebula in the constellation of Lupus. Square? Sphere? Cigar? What shape do you see?

Private Space



Via The Planetary Society, a write-up about a private effort, Axiom Space LLC, to (first) attach a module to the International Space Station and then (second) become a private free-flying space station. Will they succeed? Fingers crossed!

Battered



Today's Astronomy Picture of the Day is a close-up brought to us by the Cassini Orbiter (now entering the final stages of a very successful mission) of Saturn's moon Pandora.
