Going Up, Going Down



Today's Astronomy Picture of the Day shows the early morning launch of the Parker Solar Probe on a Delta IV Heavy while the skies are lit by the occasional Perseid meteor.

Bridge Over Stellar Waters



Today's Astronomy Picture of the Day shows a cluster of galaxies, Messier 86 (also known as The Eyes Galaxies and Arp 120), in a larger cluster of galaxies, the Virgo Cluster, and part of Markarian's Chain of galaxies. What is in the image, ghostlike? Is it a bridge between two of the galaxies?

"Mouseover" the image in the link for a guide to the objects in the picture. This is also an area worth exploring, from binoculars to larger low power/rich field telescopes. Just wander around and look what you can find!

Shock!



Today's Astronomy Picture of the Day brings us NGC 2736, in the constellation of Vela. Popularly known as The Pencil Nebula (look at the images in that second link), this nebula is the result of a supernova which occurred some 11,000 years ago.

Ruining the Shot



Today's Astronomy Picture of the Day shows a ruined astronomical shot. Or is it? A Perseid meteor passes through the frame dominated by Messier 31, The Andromeda Galaxy. Why do you think the meteor was green?

Red and Blue



The title of today's Astronomy Picture of the Day says it plain: red planet, red Moon, red Mars. But also blue water and blue sky.

Perseids



Today's Astronomy Picture of the Day is a short video showing the Perseid meteor shower's path through our solar system.

Lunar Alps



Today's Astronomy Picture of the Day shows the Moon at moonrise, rising in a state of eclipse, over the Alps in France. Did you know there are also Alps on the Moon? (There are, however, no goats known to be on the Moon—enlarge the image to see what I mean!)

Heart



Today's Astronomy Picture of the Day is a (reprocessed and enhanced) view of the heart of the Orion Nebula taken by the Hubble Space Telescope.

Full Bloodmoon



Today's Astronomy Picture of the Day shows three moments in the recent lunar eclipse, from near totality, to totality, and the moment after.

Timelapse Bloodmoon



Today's Astronomy Picture of the Day is a timed sequence of last week's "Bloodmoon" lunar eclipse over the Gulf of Poets in Italy.

Down Below



Today's Astronomy Picture of the Day shows the southern polar cap of Mars. Made up of mainly frozen carbon dioxide, the ESA's Mars Express has detected what might be a sizeable body of liquid water over 1 kilometer under the ground. What lies beneath? Salty water? Life? Let's go and see!

Just don't drink the water...

Moon Over



Today's Astronomy Picture of the Day has the blood-red eclipsed Moon and the nearly equally blood-red planet Mars rising over Rio de Janeiro. Spooooookkkyyy!!!

To the Core

Today's Astronomy Picture of the Day is a short video depicting a journey to the center of the Milky Way. Where's Beowulf Shaeffer when you need him?

Close Mars



Today's Astronomy Picture of the Day is the tale of two oppositions: Mars during a close approach in 2016 and in 2018. The globe-trotting dust storms have managed to obscure most of the surface features (can you hear the grinding of teeth of amateur astronomers everywhere?).

Dark on Dark



Today's Astronomy Picture of the Day shows dark molecular clouds, Barnard 228, in the constellation of Lupus the Wolf. Does that cloud itself look more like Goofy?

Edging Out



Today's Astronomy Picture of the Day shows us a common celestial object (a spiral galaxy) but seen but a less common vantage (edge on). Think about it. The most famous (or familiar) images of spirals are usually at an angle such that we look over and into the galaxy from above (or below...it's all relative!), not along the side.

Everything Merges with the Night



Today's Astronomy Picture of the Day brings us a merging of our world and the universe beyond: clouds of the skies of Earth (water vapor), clouds of the universe (clusters and streams and spiral arms, oh my).

Brackets



Today's Astronomy Picture of the Day are artist depictions of some of the discoveries made by the Fermi Gamma-ray Telescope. Science brackets? Why not?

Universal Plank



Today's Astronomy Picture of the Day is an image of data collected by the ESA's Planck satellite which spent 2009 to 2013 to map our universe. As a result, we've been able to stretch the estimated age of the universe back to 13.8 billion years.

RuneQuest Reboot



Really looking forward to this.

First Landing



It took a while for us to see the crisp images from Apollo 11, such as today's Astronomy Picture of the Day, as the initial images were somewhat grainy black and white television shots. I still remember that thrill (and the bigger thrill of the audio-only landing in which we ignorant "civilians" did not know of the drama of rocks and craters on the ground and computer overloads and low fuel warnings in the craft) and the thrill when the newspapers and magazines (especially Life and National Geographic) published the beautiful color images.

Drink it in. Dream mighty things.

Teapots Celestial and Grounded



Today's Astronomy Picture of the Day shows Death Valley (in the United States) at Teakettle Junction (suitably decorated). Adding to the grounded teapots is the asterism found in the constellation of Sagittarius (a great place to explore when it is visible—with either binoculars or telescopes!) known as the Teapot. Saturn and Mars are currently moseying through the area as well.

"Mouseover" the image in the link for a guide. Or look below!

Bright Focus



Today's Astronomy Picture of the Day focuses in on Cerealia Facula, on Dwarf Planet Ceres. As the Dawn vehicle reaches the end of its mission (fuel supplies are not infinite!), it has been put into a lower orbit around Ceres to make the most of the remainder of the mission. The object seen is (alas) not ice (as I had hoped) but deposits of salt (15 kilometers wide)

Ink Spill



Today's Astronomy Picture of the Day brings us an image from the Mars Reconnaissance Orbiter. What is happening on Mars? Whether it is dust, dry ice or actual liquid water or...spilled ink pots...nobody is 100% sure. Let's go and camp out and see it live!

Conjunction



Today's Astronomy Picture of the Day shows the recent conjunction between the Moon and Venus as both head towards setting. Seen in the still "just past new" phase, the Moon will brighten towards full with a eclipse (total, if you're in the path) on July 27.

Active Hunt



Today's Astronomy Picture of the Day is an artist depiction of a blazing quasar (blazar) where it is thought a neutrino, an elusive odd particle, has been confirmed to have been detected linked to a cosmological event. Neutrino Drive, anyone?

Within



Today's Astronomy Picture of the Day combines ground-based and space-based images to bring detail to Messier 57, the Ring Nebula, in the constellation of Lyra.
