A whole new world!
41 light-years away is the small, rocky planet LHS 475 b. At 99% of Earth’s diameter, it’s almost exactly the same size as our home world. This marks the first time researchers have used the Webb telescope to confirm an exoplanet.
NASA’s TESS mission hinted at the planet’s existence, making it a target of interest for Webb. Webb’s NIRSpec instrument then captured the planet easily and clearly with just 2 transit observations.
Although Webb data definitively tells us that LHS 475 b is a small rocky world, the existence and composition of its atmosphere is a mystery. The planet is a few hundred degrees warmer than Earth and very close to its star, completing an orbit in just 2 days. However, its red dwarf star is much cooler than our Sun, so scientists theorize an atmosphere is still possible. Additional follow-up observations are scheduled this summer.

I have tickets to a Charles Lloyd Concert at the Musical Instrument Museum. I am a member. I wanted to familiarize myself with the Museum before the concert so I toured it. It is an incredible treasure in my backyard. A target rich environment for photographers.

MIM began with a vision to create a musical instrument museum that would be truly global. Realizing most musical museums featured historic, primarily Western classical instruments, MIM's founder Bob Ulrich (then CEO of Target Corporation) was inspired to develop a new kind of museum that would focus on the kind of instruments played every day by people worldwide. A focus on the guest experience shaped every aspect of the museumâs development. From the beginning, our goal has been to deliver a musical experience that is enriching, inspiring, interesting, and fun.
Today, MIM has a collection of more than 7,500 instruments from more than 200 world countries and territories. The galleries reflect the rich diversity and history of many world cultures. But music and instruments also show us what we have in common a thought powerfully expressed in our motto, MUSIC IS THE LANGUAGE OF THE SOUL.
MIM's immersive exhibits foster an appreciation of diverse cultures and the craftsmanship and traditions of instrument makers from the past to the present. A visit to MIM is also about experiencing the sensory nature of music and how it affects our emotions. Through state-of-the-art, interactive media, guests can see the instruments, hear their sounds, and observe them being played in their original contexts.

Webb has revealed an exoplanet atmosphere as never seen before!
The telescope has revisited gas giant WASP-39 b to give us the first molecular and chemical profile of an exoplanet’s atmosphere, revealing the presence of water, sulfur dioxide, carbon monoxide, sodium and potassium, as well as signs of clouds. This builds on Webb’s initial look at the planet back in August, which showed the first clear evidence of carbon dioxide in a planet outside our solar system. The latest findings bode well for Webb’s capability to investigate all types of exoplanets, including the atmospheres of smaller, rocky planets like those in the TRAPPIST-1 system.
We learn about exoplanet atmospheres by breaking their light into components and creating spectra. Think of a spectrum as a barcode. Elements and molecules have characteristic signatures in that “barcode” we can read.
This planet is what is known as a “hot Saturn” — a planet about as massive as Saturn but eight times closer in orbit around its star than Mercury is around the Sun. The data shown here is taken from 3 of Webb’s science instruments. Together, they mark a series of firsts in science, including the first detection of sulfur dioxide in an exoplanet atmosphere. This, in turn, is the first concrete evidence of photochemistry — chemical reactions initiated by high-energy light, which are fundamental to life on Earth — on an exoplanet. Understanding the ratio of different elements in relation to each other also offers clues as to how the planet was formed.

Graphic of the atmospheric composition of exoplanet WASP-39 b, showing 2 graphs and a background illustration of the planet and its star.
(Left side)
The top graph shows data from Webb’s NIRISS instrument, the bottom graph data from NIRSpec. Both graphs show the amount of light blocked on the y axis versus wavelength of light on the x axis. The y axes range from 2.00 percent (less light blocked) to 2.35 percent (more light blocked). The x axes range from less than 0.1 microns to 5.5 microns. Data points are plotted as white circles with gray error bars. A curvy blue line represents a best-fit model. The NIRISS data covers a range of about 0.5 to 3.0 microns and highlights the signatures of potassium, water and carbon monoxide in semi-transparent bars of varying colors. Potassium is gray, water is blue, and carbon monoxide is red. The NIRSpec data covers a range of about 2.5 to 5.25 microns. It highlights water and carbon monoxide in addition to sulfur dioxide in green and carbon dioxide in yellow.

--Huxitar, Uygur folk musical instrument from SinKiang--
It is the first time I went to a restaurant with a DSLR(clearly a symptom of flickr addiction), I can't recall the name of the uygur instrument on the patterned wall, the restaurant was run by a hometown folk, a stout uygur woman, anyway, her pretty daughter sets up the whole place
"these instruments are very unique with a history of thousands of years, stems from Ancient Silk Road, blended with Central Plain culture, Central Asia Culture and Islamic Culture."

TRAPPIST-1 b lacked atmosphere. TRAPPIST-1 c? Much the same.
Though thought to be similar to Venus both in size and amount of radiation from its star, Webb found that TRAPPIST-1 c lacks Venus’s thick carbon dioxide-rich atmosphere. If there is an atmosphere, it’s very thin.
A refresher: TRAPPIST-1 c is the second planet from its star, the M dwarf TRAPPIST-1. M dwarf stars are intriguing because they are 10 times as common and two times more likely to have rocky planets than stars like our Sun. TRAPPIST-1 has seven!
Young M dwarf stars are energetic, emitting X-ray and UV radiation that can strip young planetary atmospheres away. It’s unknown if systems like these had enough water, carbon dioxide, or other ingredients to make atmospheres when the planets formed.
Webb is so sensitive that it can search for elements and molecules like oxygen, nitrogen, and carbon dioxide in exoplanet atmospheres. The mystery remains — can planets orbiting small M dwarfs sustain the atmospheres needed to support life as we know it?

This image: This light curve shows the change in brightness of the TRAPPIST-1 system as the second planet, TRAPPIST-1 c, moves behind the star. This phenomenon is known as a secondary eclipse. Astronomers used Webb’s Mid-Infrared Instrument (MIRI) to measure the brightness of mid-infrared light. When the planet is beside the star, the light emitted by both the star and the dayside of the planet reach the telescope, and the system appears brighter. When the planet is behind the star, the light emitted by the planet is blocked and only the starlight reaches the telescope, causing the apparent brightness to decrease.

Image description: Infographic titled “Rocky Exoplanet TRAPPIST-1 c Secondary Eclipse Light Curve, MIRI Time-Series Photometry (F1500W).” At the top of the infographic is a diagram showing a planet moving behind its star (a secondary eclipse). Below the diagram is a graph showing the change in brightness of 15-micron light emitted by the star-planet system over the course of nearly 2 hours. The diagram and graph are aligned vertically to show the relationship between the geometry of the star-planet system as the planet orbits, and the measurements on the graph. The infographic shows that the brightness of the system decreases slightly as the planet moves behind the star.

England id very strict where safety is concerned.
Here a few examples, hard hats and old fashioned sand-filled fire-buckets
This was the day the new building of BBC Sheffield started...
The Safety helmets were somewhere else, loved the placement!
All the rest is in Pickering station, manned by all the volunteers.
Love all the colours, these are good tools.
Keep safe!
I wish you a day full of beauty and thank you for your visit, Magda, (*_*)

Instruments being silent can take the ambiance right out of a room. Either a guitar, piano, flute, banjo or what have you, when played they warm a room up. That’s not to say the player needs be a professional. I think most people would be happy to be able to play for their own amusement. Playing for your own pleasure is most likely the reason a lot of us ever picked up an instrument in the first place. You may never be a rock star or concert pianist. That’s not a good enough reason not to pick up an instrument, play around and dream. Thanks for viewing my work. Gratitude and Kindness can pave the way for a happier journey.
