“Consider again that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species lived there - on a mote of dust suspended in a sunbeam.”
Pale Blue Southwest
"… how humble our beginnings, how many rivers we had to cross to find our way."
Your Friday moment of Zen, timelapse images of the American Southwest set to Carl Sagan’s “Pale Blue Dot”. There’s no bad time to remember these words, our place on Earth, and our place in the universe.

Fall is coming to an end, the sun sinks lower every day, and the chill of early winter has fallen across much of the northern hemisphere.
That means that, in places where leaves actually change color (AKA “not in Austin, where I live”), green has long given way to fiery reds and oranges, and that fire has since fallen to the ground, extinguished by garden rakes or decomposition, or blown out by brisk winds.
Hold on to these macro photos of color-changing leaves as a memory of the passing season. As the days have grown shorter, these plants have stopped producing as much green chlorophyll, and their carotenoids and anthocyanins shine through in bright canary and deep vermillion hues. You can also observe their veins, weaving beneath the leaf’s scaly epidermis, cutting cracks like a drying desert pond.
Here’s a less poetic diagram:
This is the beauty that lies in knowing, the science in the details, the wonder of the changing seasons.
Aorounga Crater, Chad
This image from Japan’s ALOS satellite shows the Aorounga Crater in northern Chad.
The crater is just south of the Tibesti Mountains, a range of inactive – with some potentially active – volcanoes in the central Sahara desert.
Measuring about 12 km across, the crater was created by a meteorite impact about 340 million years ago.
Clearly visible is the dark, central peak, caused by material splashing up after the impact, similar to how water bounces back up when a stone is thrown in. This peak is surrounded by a low, sand-filled ring, which is surrounded by another ring of rock from when the material was thrown outwards. A distinctive low, sand-filled trough circles the others – the outer edges of the initial impact.
The linear rock ridges that run diagonally across this image are ‘yardangs’ and are formed by wind erosion. Here, we can clearly see how the wind blows from northeast to southwest. Sand dunes form in the wind-cut valleys between the rock ridges of the yardangs.
Japan’s Advanced Land Observation Satellite captured this image on 3 November 2010. ALOS was supported as a Third Party Mission, which means that ESA used its multimission ground systems to acquire, process, distribute and archive data from the satellite to its user community.
This image is featured on the Earth from Space video programme.
Cardiac MRI, is a medical imaging technology for the non-invasive assessment of the function and structure of the cardiovascular system. It is derived from and based on the same basic principles as magnetic resonance imaging (MRI) but with optimization for use in the cardiovascular system. These optimizations are principally in the use of ECG gating and rapid imaging techniques or sequences. By combining a variety of such techniques into protocols, key functional and morphological features of the cardiovascular system can be assessed.
The world has more than enough blind believers: Forget about the “Believer’s Prayer”…! Have you committed to the Rational Enquirers Life yet?
Rational Enquirers Commitment: “Recognizing the harmful confusion and suffering inflicted on humanity throughout history…and oppression promoted through ignorance, bigotry and superstition, by organized believers…I resist the temptation to fall back on to indoctrinated, comforting myths and fables…and commit myself, instead, to the rational exploration and understanding of reality…to hold and promote views that are supported by the preponderance of verifiable, scientific evidence…for the benefit of all humanity…and our interconnected habitat…so help me atheists…”
