Forgive my indulgence!
I wish I understood where my fascination with the night sky came from. Not that I am anything other than an amateur gazer (of the night sky, I should hasten to add!). I have never taken the trouble to gain any real knowledge.
Yet, some of the most serene moments of my life have been when I have been alone at sea under a night sky.
OK, that’s enough wallowing for anyone!
The last week has been an important one for those that take an interest in the planets in our solar system, or to be specific, take an interest in Jupiter.
For as EarthSky reported on the 8th April:
Today – April 8, 2017 – the planet Jupiter is closest to Earth for this year.
Yet yesterday was Jupiter’s opposition, when Earth flew between Jupiter and the sun, placing Jupiter opposite the sun in our sky. You’d think Jupiter was closest to Earth for 2017 yesterday as well … and yet it wasn’t. It’s closest to Earth for 2017 today, April 8, coming to within 414 million miles (666 million km).
EarthSky also included this image:
Then, Mother Nature Network yesterday presented more information:
Jupiter strikes a pose for Hubble portrait
April 12, 2017
The article included this stunning image of Jupiter.
Jaymi went on to write:
Here’s what some of the other details in the image mean:
The NASA/ESA Hubble Space Telescope reveals the intricate, detailed beauty of Jupiter’s clouds as arranged into bands of different latitudes. These bands are produced by air flowing in different directions at various latitudes. Lighter coloured areas, called zones, are high-pressure where the atmosphere rises. Darker low-pressure regions where air falls are called belts. Constantly stormy weather occurs where these opposing east-to-west and west-to-east flows interact. The planet’s trademark, the Great Red Spot, is a long-lived storm roughly the diameter of Earth. Much smaller storms appear as white or brown-coloured ovals. Such storms can last as little as a few hours or stretch on for centuries.
The Great Red Spot is an anticyclonic storm that is so large that Earth would fit inside it. That stormy spot — which is actually shrinking, though astronomers don’t know why — gives us a great perspective for understanding just how huge Jupiter is compared to our own blue dot in the solar system.
Finally, I’m taking the liberty of republishing in full an item that appeared on The Smithsonian site on April 7th.

Hubble Snags Splendid Snapshot of Jupiter
The perfect photographic conditions make for a grand view of the gas giant
April 7, 2017
It’s been 27 years since the Hubble Space Telescope went into orbit, and the geriatric observatory is still going strong. When the telescope recently trained its sights on the solar system’s largest planet, the results were spectacular—proof that for the stellar spectator, age is but a number.
The image above is the latest picture of Jupiter. The snapshot was taken by Hubble on April 3 with the help of the telescope’s Wide Field Camera 3, a high-res instrument that lets the telescope observe using different wavelengths. It combines light on the visible, ultraviolet, and infrared spectrum to create an image of a massive planet in constant atmospheric flux.
In a press release, the European Space Agency, which co-runs Hubble with NASA, said that Hubble was able to take advantage of the planet’s current opposition with Earth to take the close-up. At the moment, Jupiter is lined up perfectly with the sun, and Earth is lined up with both the sun and Jupiter. Think of it as a truly heavenly photographic opportunity—a chance to look at the planet head-on. Better yet, Jupiter’s position relative to the sun means that it’s brighter than at any other time of year, which lets telescopes trained on the gigantic planet see even more detail than usual.
As The Washington Post’s Amy B. Wang notes, there were no new discoveries in the picture per se, but that doesn’t mean there’s nothing to look at. As ESA explains, scientists will compare the photo to previous views of the planet to hopefully learn more about the atmosphere. And for the rest of us, there’s a strangely soothing view of Jupiter’s layered cloud bands and impressive vortices.
The gas giant is thought to have sucked up most of the space debris left over after the sun formed, grabbing dust and gas with gravity. Scientists think it has two times as much debris as all of the other bodies in the solar system combined—and all of that material swirls through cloud layers in its quickly-rotating atmosphere.
Since Jupiter doesn’t exactly have a surface, it has nothing to slow the spots and vortices that appear in its atmosphere. The most famous, the Great Red Spot, is thought to have been swirling around for more than 150 years, and even though it’s unclear which gases give it that red hue, it’s the planet’s most recognizable feature. As NASA writes, the cloudiness of Jupiter’s atmosphere makes it hard to understand what might be contributing to it. But that doesn’t decrease its allure.
Want to delve even further into the mesmerizing bands of a huge planet’s atmosphere? A high-res version of the snapshot is available online. And if you prefer seeing things live, it’s a great time to check out Jupiter through in the night sky. You can find Jupiter in the east right after the sun goes down—a massive mystery that’s brighter than any star.

Let me finish up with another incredible fact.
Namely, that the universe came into existence some 13.82 billion years ago. The power of natural evolution that came with that event eventually brought along homo sapiens some 200,000 years ago. 200,000 is 0.0000145 of 13.82 billion.
Or to put it another way, we humans have only been a part of this universe for 1/10th of 1% of the life of said universe! (Oh, and dogs came along 100,000 years ago!)
I also share your fascination with the heavens, Paul. So much so that I wanted to be an astronaut. There is something soothing to the soul just gazing upon the stars.
Jupiter is a fascinating planet & maybe one day we will explore its moons.
I liked your diversion.

Especially so when out at sea. For on very clear, calm nights one can see the stars down almost to the horizon in every direction. It’s very humbling! A reminder of how insignificant a person can be at times. Indeed, this planet can be.
Susan, thank you very much for putting up with my excursions! 😊

My hubby has a fascination too for the night sky and has a small telescope he looks at the stars with.. The Hubble Space Telescope has provided us with tremendous views and we can only gape in open mouth at the vastness and diversity of outer space.. As we contemplate the zillions of planets, stars and galaxies that are expanding and growing into new worlds..
Amazing post and photos Paul.. Thank you for sharing

Ah, yes, I believe you have mentioned before your husband looking at the stars through his telescope! I don’t know …… one minute we are chatting about growing tomatoes and then a moment later it’s about Jupiter and the night skies! What next? 😍

I love looking at the night sky. We have too much light where I am but I’ve been watching the moon pass by every morning around 3. Shines in my window and wakes me up. It’s worth it though. I love learning about the Universe. There is supposed to be some new information released today. I’ll try to get it.
