Among the most fundamental questions in astronomy is: How did the first stars and galaxies form? NASA’s James Webb Space Telescope is already providing new insights into this question. One of the largest programs in Webb’s first year of science is the JWST Advanced Deep Extragalactic Survey, or JADES, which will devote about 32 days of telescope time to uncover and characterize faint, distant galaxies. While the data is still coming in, JADES already has discovered hundreds of galaxies that existed when the universe was less than 600 million years old. The team also has identified galaxies sparkling with a multitude of young, hot stars. “With JADES, we want to answer a lot of questions, like: How did the earliest galaxies assemble themselves? How fast did they form stars? Why do some galaxies stop forming stars?” said Marcia Rieke of the University of Arizona in Tucson, co-lead of the JADES program.

Star Factories Ryan Endsley of the University of Texas at Austin led an investigation into galaxies that existed 500 to 850 million years after the big bang. This was a crucial time known as the Epoch of Reionization. For hundreds of millions of years after the big bang, the universe was filled with a gaseous fog that made it opaque to energetic light. By one billion years after the big bang, the fog had cleared and the universe became transparent, a process known as reionization. Scientists have debated whether active, supermassive black holes or galaxies full of hot, young stars were the primary cause of reionization.

As part of the JADES program, Endsley and his colleagues studied these galaxies with Webb’s NIRSpec (Near-Infrared Spectrograph) instrument to look for signatures of star formation – and found them in abundance. “Almost every single galaxy that we are finding shows these unusually strong emission linesignatures indicating intense recent star formation. These early galaxies were very good at creating hot, massive stars,” said Endsley.

These bright, massive stars pumped out torrents of ultraviolet light, which transformed surrounding gas from opaque to transparent by ionizing the atoms, removing electrons from their nuclei. Since these early galaxies had such a large population of hot, massive stars, they may have been the main driver of the reionization process. The later reuniting of the electrons and nuclei produces the distinctively strong emission lines.

Endsley and his colleagues also found evidence that these young galaxies underwent periods of rapid star formation interspersed with quiet periods where fewer stars formed. These fits and starts may have occurred as galaxies captured clumps of the gaseous raw materials needed to form stars. Alternatively, since massive stars quickly explode, they may have injected energy into the surrounding environment periodically, preventing gas from condensing to form new stars.

The Early Universe Revealed

Another element of the JADES program involves the search for the earliest galaxies that existed when the universe was less than 400 million years old. By studying these galaxies, astronomers can explore how star formation in the early years after the big bang was different from what is seen in current times. The light from faraway galaxies is stretched to longer wavelengths and redder colors by the expansion of the universe – a phenomenon called redshift. By measuring a galaxy’s redshift, astronomers can learn how far away it is and, therefore, when it existed in the early universe. Before Webb, there were only a few dozen galaxies observed above a redshift of 8, when the universe was younger than 650 million years old, but JADES has now uncovered nearly a thousand of these extremely distant galaxies.

The gold standard for determining redshift involves looking at a galaxy’s spectrum, which measures its brightness at a myriad of closely spaced wavelengths. But a good approximation can be determined by taking photos of a galaxy using filters that each cover a narrow band of colors to get a handful of brightness measurements. In this way, researchers can determine estimates for the distances of many thousands of galaxies at once.

Kevin Hainline of the University of Arizona in Tucson and his colleagues used Webb’s NIRCam (Near-Infrared Camera) instrument to obtain these measurements, called photometric redshifts, and identified more than 700 candidate galaxies that existed when the universe was between 370 million and 650 million years old. The sheer number of these galaxies was far beyond predictions from observations made before Webb’s launch. The observatory’s exquisite resolution and sensitivity are allowing astronomers to get a better view of these distant galaxies than ever before.

“Previously, the earliest galaxies we could see just looked like little smudges. And yet those smudges represent millions or even billions of stars at the beginning of the universe,” said Hainline. “Now, we can see that some of them are actually extended objects with visible structure. We can see groupings of stars being born only a few hundred million years after the beginning of time.” “We’re finding star formation in the early universe is much more complicated than we thought,” added Rieke. These results are being reported at the 242^nd meeting of the American Astronomical Society in Albuquerque, New Mexico.

The James Webb Space Telescope is the world’s premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

Brian Douglas Wilson (born June 20, 1942 Inglewood, CA) is an American musician, singer, songwriter, and record producer who co-founded the Beach Boys. Often called a genius for his novel approaches to popcomposition, extraordinary musical aptitude, and mastery of recording techniques, he is widely acknowledged as one of the most innovative and significant songwriters of the 20th century. His best-known work is distinguished for its high production values, complex harmonies and orchestrations, layered vocals, and introspective or ingenuous themes. Wilson is also known for his formerly high-ranged singing and for his lifelong struggles with mental illness.

Raised in Hawthorne, California, Wilson’s formative influences included George Gershwin, the Four Freshmen, Phil Spector, and Burt Bacharach. In 1961, he began his professional career as a member of the Beach Boys, serving as the band’s songwriter, producer, co-lead vocalist, bassist, keyboardist, and de factoleader. After signing with Capitol Records in 1962, he became the first pop artist credited for writing, arranging, producing, and performing his own material. He also produced other acts, most notably the Honeys and American Spring. By the mid-1960s he had written or co-written more than two dozen U.S. Top 40 hits, including the number-ones “Surf City” (1963), “I Get Around” (1964), “Help Me, Rhonda” (1965), and “Good Vibrations” (1966). He is considered among the first music producer auteurs and the first rock producers to apply the studio as an instrument.

In 1964, Wilson had a nervous breakdown and resigned from regular concert touring, which led to more refined work, such as the Beach Boys’ Pet Sounds and his first credited solo release, “Caroline, No” (both 1966), as well as the unfinished album Smile. As he declined professionally and psychologically in the late 1960s, his contributions to the band diminished, and legends grew around his lifestyle of seclusion, overeating, and drug abuse. His first comeback, divisive among fans, yielded the would-be solo effort The Beach Boys Love You (1977). In the 1980s he formed a controversial creative and business partnership with his psychologist, Eugene Landy, and relaunched his solo career with the album Brian Wilson (1988). Wilson disassociated from Landy in 1991 and went on to tour regularly as a solo artist from 1999 to 2022.

Heralding popular music’s recognition as an art form, Wilson’s accomplishments as a producer helped initiate an era of unprecedented creative autonomy for label-signed acts. The youth culture of the 1960s is commonly associated with his early songs, and he is regarded as an important figure to many music genres and movements, including the California sound, art pop, psychedelia, chamber pop, progressive music, punk, outsider, and sunshine pop. Since the 1980s, his influence has extended to styles such as post-punk, indie rock, emo, dream pop, Shibuya-kei, and chillwave. Wilson’s accolades include numerous industry awards, inductions into multiple music halls of fame, and entries on several “greatest of all time” critics’ rankings. His life was dramatized in the 2014 biopic Love & Mercy.

Chester Burton Atkins (June 20, 1924 – June 30, 2001), known also as “Mr. Guitar” and “The Country Gentleman“, was an American musician who, along with Owen Bradley and Bob Ferguson, helped create the Nashville sound, the country music style which expanded its appeal to adult pop music fans. He was primarily a guitarist, but he also played the mandolin, fiddle, banjo, and ukulele, and occasionally sang.

Atkins’s signature picking style was inspired by Merle Travis. Other major guitar influences were Django Reinhardt, George Barnes, Les Paul, and, later, Jerry Reed. His distinctive picking style and musicianship brought him admirers inside and outside the country scene, both in the United States and abroad. Atkins spent most of his career at RCA Victor and produced records for the Browns, Hank Snow, Porter Wagoner, Norma Jean, Dolly Parton, Dottie West, Perry Como, Floyd Cramer, Elvis Presley, the Everly Brothers, Eddy Arnold, Don Gibson, Jim Reeves, Jerry Reed, Skeeter Davis, Waylon Jennings, Roger Whittaker, Ann-Margret and many others.

Rolling Stone credited Atkins with inventing the “popwise ‘Nashville sound’ that rescued country music from a commercial slump” and ranked him number 21 on their list of “The 100 Greatest Guitarists of All Time”.Among many other honors, Atkins received 14 Grammy Awards and the Grammy Lifetime Achievement Award. He also received nine Country Music Association awards for Instrumentalist of the Year. He was inducted into the Rock & Roll Hall of Fame, the Country Music Hall of Fame and Museum, and the Musicians Hall of Fame and Museum. George Harrison was also inspired by Chet Atkins; early Beatles songs such as “All My Loving” show the influence.

Atkins was born on June 20, 1924, in Luttrell, Tennessee, near Clinch Mountain. His parents divorced when he was six years old, after which he was raised by his mother. He was the youngest of three boys and a girl. He started out on the ukulele, later moving on to the fiddle, but he made a swap with his brother Lowell when he was nine: an old pistol and some chores for a guitar.

On “Freedom’s Eve,” or the eve of January 1, 1863, the first Watch Night services took place. On that night, enslaved and free African Americans gathered in churches and private homes all across the country awaiting news that the Emancipation Proclamation had taken effect. At the stroke of midnight, prayers were answered as all enslaved people in Confederate States were declared legally free. Union soldiers, many of whom were black, marched onto plantations and across cities in the south reading small copies of the Emancipation Proclamation spreading the news of freedom in Confederate States. Only through the Thirteenth Amendment did emancipation end slavery throughout the United States.

But not everyone in Confederate territory would immediately be free. Even though the Emancipation Proclamation was made effective in 1863, it could not be implemented in places still under Confederate control. As a result, in the westernmost Confederate state of Texas, enslaved people would not be free until much later. Freedom finally came on June 19, 1865, when some 2,000 Union troops arrived in Galveston Bay, Texas. The army announced that the more than 250,000 enslaved black people in the state, were free by executive decree. This day came to be known as “Juneteenth,” by the newly freed people in Texas.

Albert King (1912–1981), known as Bertie King, was a Jamaican jazz and mento musician. He played the clarinet and the saxophone.

King was born in Panama, and raised in Kingston, where he attended Alpha Boys School.

During the 1930s he led his own band, Bertie King and his Rhythm Aces, described at the time as “Jamaica’s Foremost Dance Orchestra”. In 1936 he left for England, sailing on the same ship as his friend Jiver Hutchinson. In London he joined Ken Snakehips Johnson‘s West Indian Dance Band, and later played with Leslie Hutchinson’s band. He also worked with visiting American musicians including Benny Carter, George Shearing and Coleman Hawkins. In 1937 he recorded four sides in the Netherlands with Benny Carter, and in 1938 he recorded with Django Reinhardt in Paris. In 1939 he joined the Royal Navy. He left the Navy in 1943 and formed his own band, also working and recording with Nat Gonella.

King returned to Jamaica in 1951, where he started his own band, known as the Casa Blanca Orchestra, playing in the mento style. Since there were no Jamaican record labels at this time, he arranged for his recordings to be pressed in a plant in Lewisham, England, owned by Decca Records. He returned a number of times to England, working and recording with Kenny Baker, George Chisholm, Chris Barber, Kenny Graham and Humphrey Lyttelton, and also toured in Asia and Africa with his own band. During this period he also played and recorded in London with some of the leading Trinidadian calypsonians. He was noted for his impassive demeanour on stage, which belied an expressive playing style.

King led the Jamaica Broadcasting Corporation‘s house band in the 1950s; his sidemen included Ernest Ranglin and Tommy Mowatt.^[1] He recorded extensively with this outfit. In 1965 he moved to the USA. His last known public performance was at Jamaican Independence Day celebrations in New York City in 1967. He died in the USA in 1981.

Originally discovered during the Voyager flybys of Saturn in the 1980s, nobody has ever seen anything like it anywhere else in the Solar System. Acquiring its first sunlit views of far northern Saturn in late 2012, the Cassini spacecraft’s wide-angle camera recorded this stunning, false-color image of the ringed planet’s north pole. The composite of near-infrared image data results in red hues for low clouds and green for high ones, giving the Saturnian cloudscape a vivid appearance. This and similar images show the stability of the hexagon even 20+ years after Voyager. Movies of Saturn’s North Pole show the cloud structure maintaining its hexagonal structure while rotating. Unlike individual clouds appearing like a hexagon on Earth, the Saturn cloud pattern appears to have six well defined sides of nearly equal length. Four Earths could fit inside the hexagon. Beyond the cloud tops at the upper right, arcs of the planet’s eye-catching rings are tinted bright blue.
