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.

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.

Two Years Out


We're two years out from the second edition setting of this classic science fiction roleplaying game.

You'll want to click on that one to get the full effect.

Edge Case Scenario



Today's Astronomy Picture of the Day is from the July 13, 2018 eclipse of the Sun. What? You missed it? Right there! That..nick...

Not all eclipses are total and not all partial eclipses are noticeable! That's part of the fun in eclipse chasing, getting those rarities.

Jumbles



Today's Astronomy Picture of the Day shows a galaxy that had a bad day and is still in recovery mode. Centaurs A is an "active galaxy". Two galaxies "interacted" and the results can be seen in a jumble of star clusters, dust clouds and more. Top it off with a central black hole that is slowly consuming the dust and other material that comes its way.

Variations on a Theme



Today's Astronomy Picture of the Day is a Hubble Space Telescope view of variable star (stars, actually) R Aquarii. Hubble brings us fine detail such as this, but even a modest pair of binoculars can show the variations in brightness if you track the stars over time.

Variable stars are one area where amateurs can continue to make a contribution. There are so many to observe that there are not enough "professional scale" instruments to observe them. Amateurs have contributed observations for over one hundred years.

Might I recommend a book to you?

Wisps



Today's Astronomy Picture of the Day is a short video showing noctilucent clouds over the skies of Paris. I was treated last night not only to a nice view of such clouds, but also the Belt of Venus featured here a few days ago.

(The above image is from a prior APOD, by the way.)

Clear Approach



Today's Astronomy Picture of the Day shows a desert road at night...seemingly leading straight to Mars. If only we could get up enough speed to make the leap across that gap!

Plumbing and Politics



It appears that the United States is...raising a stink...over some of the sub-systems of the International Space Station that they have purchased from the Russians.

This is not the first time that this sub-system has been an issue. In March 2009, it was involved in a form of brinkmanship. Later that year, when 13 people were on the ISS at once, the US facility broke down, putting strain on the Russian facility.

Let's be honest, it's not like they can pull over at a rest stop.


Ring Structure



Today's Astronomy Picture of the Day shows the extended spiral structure found in the same field of view as LL Pegasi. It's not a spiral galaxy. Probably it is a planetary nebula in the making. If seen from the side, perhaps it would resemble a painting by Chesley Bonestell?

Perpetual Light



Today's Astronomy Picture of the Day is a midnight scene in northern Denmark. During the summer season, the Sun never quite goes away!

Dragon in the Sea



From a 1968 book (Explorers of the Deep). Do I recognize a certain vehicle thought up by Frank Herbert, later patented by somebody else?

Selfie



Alan Bean does a selfie. Of sorts. Apollo 12 visits Surveyor 2.

Mission Line



A visual mission history for the Jet Propulsion Laboratory. Some of these destinations need followup. Do we have the vision to do so?
