The James Webb Space Telescope

Talk about looking up at the starry night!

I am sure that many of you have seen the latest images but still for those that have not…

ooOOoo

First the BBC presented a report on the 25th December, 2022. This is part of what they described:

James Webb telescope: Amazing images show the Universe as never before

The Tarantula Nebula: Only 161,000 light years from Earth, this is a place where thousands of stars were born

By Jonathan Amos, BBC Science Correspondent

It was the $10bn gift to the world. A machine that would show us our place in the Universe.

The James Webb Space Telescope (JWST) was launched exactly a year ago, on Christmas Day. It had taken three decades to plan, design and build.

Many wondered whether this successor to the famed Hubble Space Telescope could actually live up to expectations. 

We had to wait a few months while its epic 6.5m primary mirror was unpacked and focused, and its other systems tested and calibrated.

The first thing you have to remember about James Webb is that it is an infrared telescope. It sees the sky at wavelengths of light that are beyond what our eyes are able to discern. 

Astronomers use its different cameras to explore regions of the cosmos, such as these great towers of gas and dust. The Pillars were a favourite target of Hubble. It would take you several years travelling at the speed of light to traverse this entire scene.

Now we go to the NASA site for more of the JWST:

First Images from the James Webb Space Telescope

The dawn of a new era in astronomy has begun as the world gets its first look at the full capabilities of NASA’s James Webb Space Telescope, a partnership with ESA (European Space Agency) and CSA (Canadian Space Agency). The telescope’s first full-color images and spectroscopic data were released during a televised broadcast at 10:30 a.m. EDT (14:30 UTC) on Tuesday, July 12, 2022, from NASA’s Goddard Space Flight Center in Greenbelt, Maryland. These listed targets below represent the first wave of full-color scientific images and spectra the observatory has gathered, and the official beginning of Webb’s general science operations. They were selected by an international committee of representatives from NASA, ESA, CSA, and the Space Telescope Science Institute.

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.

Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.

This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.

Called the Cosmic Cliffs, Webb’s seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest “peaks” in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image.

Stephan’s Quintet, a visual grouping of five galaxies, is best known for being prominently featured in the holiday classic film, “It’s a Wonderful Life.” Today, NASA’s James Webb Space Telescope reveals Stephan’s Quintet in a new light. This enormous mosaic is Webb’s largest image to date, covering about one-fifth of the Moon’s diameter. It contains over 150 million pixels and is constructed from almost 1,000 separate image files. The information from Webb provides new insights into how galactic interactions may have driven galaxy evolution in the early universe.

With its powerful, infrared vision and extremely high spatial resolution, Webb shows never-before-seen details in this galaxy group. Sparkling clusters of millions of young stars and starburst regions of fresh star birth grace the image. Sweeping tails of gas, dust and stars are being pulled from several of the galaxies due to gravitational interactions. Most dramatically, Webb captures huge shock waves as one of the galaxies, NGC 7318B, smashes through the cluster.

Some stars save the best for last.

The dimmer star at the center of this scene has been sending out rings of gas and dust for thousands of years in all directions, and NASA’s James Webb Space Telescope has revealed for the first time that this star is cloaked in dust.

Two cameras aboard Webb captured the latest image of this planetary nebula, cataloged as NGC 3132, and known informally as the Southern Ring Nebula. It is approximately 2,500 light-years away.

Webb will allow astronomers to dig into many more specifics about planetary nebulae like this one – clouds of gas and dust expelled by dying stars. Understanding which molecules are present, and where they lie throughout the shells of gas and dust will help researchers refine their knowledge of these objects.

NASA’s James Webb Space Telescope has captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding a hot, puffy gas giant planet orbiting a distant Sun-like star.

The observation, which reveals the presence of specific gas molecules based on tiny decreases in the brightness of precise colors of light, is the most detailed of its kind to date, demonstrating Webb’s unprecedented ability to analyze atmospheres hundreds of light-years away.

While the Hubble Space Telescope has analyzed numerous exoplanet atmospheres over the past two decades, as in capturing the first clear detection of water in 2013, Webb’s immediate and more detailed observation marks a giant leap forward in the quest to characterize potentially habitable planets beyond Earth.

Just a few of the very special photographs. They are remarkable!

December’s issue of the Science magazine had an article in which there was a paragraph that described:

The first data and images beamed back to Earth by JWST suggest it was all worthwhile. They are “beautiful” and ‘mind-blowing,” according to astronomers who have spoken with Science. It was like putting on infrared glasses, one said, and seeing the universe anew.

The GOLDEN EYE, by Daniel Clery

Imagine that just, say, 25 years ago these images and this mission would have been science fiction and now it is a reality.

I will leave you with a quotation from that SCIENCE magazine (16th December): “Politicians and pundits often make up whatever suits their political goals about science, but scientists recognize how little we understand about the Universe. As Kennedy said, “The greater our knowledge increases, the greater our ignorance unfolds.“”

Dear good people, I am taking a small break from blogging and will be back with you on the 1st January, 2023; in other words in a week’s time.

Beautiful photographs from Alex!

Last Friday I received an email from my son in which he said: “… bit chilly here -9C (16F) overnight but we heard that some short-eared owls had turned up in a nature reserve near Minehead so have been down there the last few days, here are the pictures.”

He included the many photographs separately as well. If you want to see more then please go here plus I want to credit Alex Handover as the photographer.

Here they are:

In the interim, wherever you are, please be careful and take care.

A very small step.

But an important one!

From the 21st November until the 23rd Sunshine Solar installed a solar panel system. But we were then told to wait until Pacific Power had come to the house to put in a new electricity meter. Last Thursday, 1st December, Brent from Pacific Power called by and replaced our electricity meter. He replaced it with a bi-directional meter that when we were producing more power than we are consuming then the surplus would be ‘banked’ to be used at times when we required the surplus.

This was the result of us investing in a ground-mounted solar system.

We purchased the system from Solar Sunshine after doing a great deal of research. Indeed Brent said that they were a great company.

The other thing that we had no choice over was to install a ground-mounted system some 120 feet from the house. Because neither the house nor the roof face East and therefore are no use for solar. But as Brent pointed out last Thursday the ground-mounted system, despite being more expensive, was a good alternative to the roof system because new roof tiles were irrelevant.

The system consists of 30 individual panels capable of producing a maximum output of 65 amps at 240 volts; in other words 15,600 watts!

Yesterday, Cory and Brandon (sp?) came out to the system and checked that it was alright. Plus they gave us an digital application so we could see how much power we were generating, plus more, and they also took some photographs, that I offer you now.

This last photograph was one taken by yours truly with Cory on the left and Brandon on the right with Jeannie in the middle.

Finally, the ‘app’ is going to be very useful.

Already it shows that last Saturday the array produced 29 kilowatts and then yesterday, the 4th December, the array produced 22.9 kilowatts and these were by no means sunlit days all the time. That brings the total for all 5 days in December, in other words since the system went live, to 91.1 kilowatts as of 15:27 PT on the 5th.

We are most pleased with the company and the installation.

I can’t put it better than the email that I received recently from Chris. Here it is:

Hi Paul

Happy Thanksgiving. Hopefully you had a far better one than the last time I celebrated with American friends when I lived in Indonesia. We ended up having to evacuate the house (including the deputy US ambassador) as the kitchen caught fire!

It’s been a bit of a journey writing the post as so many adventures with the dogs came back to me. In the end I focussed on the first one Princess and the latest Tinker. I hope it’s OK. Let me know if not, as I can always rewrite it. There are so many other dogs I could have mentioned which is the scary thing! Still, the copy is attached and I’m sending photos using WeTransfer.com. They’ll send you an email with a link to download the pics. It’s totally safe and free (It’s been a godsend for designing book covers as it stops emails getting clogged up). I’ve put far too many pics in there so please feel free to use the ones you like and discard others.

Thank you so much for letting me do this post. It’s been quite emotional, but put a huge smile on my face all week.

Best wishes

Chris
