Star Dust



Today's Astronomy Picture of the Day brings us dusty lanes in NGC 4302 and NGC 4298. How many other galaxies can you spot in the picture?

Tumbling Dice



Today's Astronomy Picture of the Day is a series of radar images of Asteroid 2014 JO24. A "Potentially Hazardous Asteroid", it's probably prudent to collect data on this whirling bullet.

Phospor



Today's Astronomy Picture of the Day has phosphorescent glows above and below. Growing up with the sea-related stories by Arthur C. Clarke, his descriptions of glowing plankton and the Milky Way of the southern hemisphere fascinated me. I hope to someday see both!

Plumes



Today's Astronomy Picture of the Day illuminates recent discoveries by the hard-working Cassini orbiter around Saturn. Does life lurk under the seas of Enceladus?

Down Down Down Down



Today's Astronomy Picture of the Day brings us beyond the blue event horizon. A supermassive black hole consumes a star, the accretion disk heats up and produces a jet. Astounding universe we live in!

Persistence of Life



Today's Astronomy Picture of the Day shows a tardigrade. An alien on Earth? Probably not, but a good example of the ability of life to adapt at the extremes.

Shadow and Moons



Today's Astronomy Picture of the Day is a Damien Peach wonder. Jupiter with intricate cloudscape, Ganymede (and shadow) and Io overhead.

Today's Astronomy Picture of the Day gives us a deep look at Cygnus. Astounding stuff.

Origin Story

The very secret origins of the Wild Cards novels and stories aren't very secret, but this essay by John Jos. Miller gives a nice new perspective on what happened. And they say nothing ever comes out of playing games!

JWST



Today's Astronomy Picture of the Day shows the James Webb Space Telescope in the clean room at Goddard. I really hope this thing works!

Odometer



For a mission slated for a mere ninety "sols", Opportunity is doing pretty good.

Phasing



Today's Astronomy Picture of the Day shows several months on phase changes for Venus. Which phase is the brightest in the evening (or morning) sky?

Starlight Moon



Today's Astronomy Picture of the Day brings us the starlit face of Mimas. Another wonderful image courtesy of the hard-working Cassini orbiter!
