The Mystical Glow of the Night Sky: Exploring Zodiacal Light
Zodiacal light, seen before sunrise, is sunlight scattering off interplanetary dust in the zodiacal cloud. It represents a cosmic connection, best viewed in dark, clear locations during specific times of the year.
Last Updated on June 23, 2025 by Daily News Staff
Have you ever looked up at the night sky and noticed a faint glow, gracefully extending from the horizon in a triangular shape? This enchanting phenomenon is known as zodiacal light, often referred to as “false dawn” when it’s visible just before sunrise. While it may seem like a mere trick of the light, the zodiacal light holds a fascinating story about the universe surrounding our planet.
The Science Behind Zodiacal Light
Zodiacal light is the result of sunlight scattering off interplanetary dust, creating a delicate illumination in the night sky. This dust resides in a thick, pancake-shaped cloud known as the zodiacal cloud, which orbits in the ecliptic plane of our Solar System. Ranging from 10 to 300 micrometers in size, these tiny particles have masses that can span from one nanogram to several micrograms. Together, they contribute to what we see as a soft glow, complementing the natural light of a moonless night.
Interestingly, zodiacal light can be seen most effectively in dark locations, far away from the interference of city lights or moonlight. When conditions are perfect—a clear night with minimal light pollution—this soft glow stretches from the direction of the Sun, gracefully illuminating the darker parts of the sky. It’s most prominent in the western sky during spring after sunset and in the eastern sky during autumn before dawn.
The Origins of Cosmic Dust
The source of the dust that creates zodiacal light has long been a subject of exploration and debate. Initially thought to originate from active comet tails or collisions among asteroids, recent research suggests that a significant portion of the dust comes from the gradual fragmentation of dormant comets, specifically those in the Jupiter-family category.
When comets break apart, they send tiny fragments scattering through space. As these particles eventually disintegrate further due to collisions and space weathering, they continue to replenish the zodiacal dust cloud. This dynamic relationship ensures that our view of zodiacal light is not just a fleeting moment, but a persistent feature of our cosmic environment.
Viewing Zodiacal Light: Tips and Tricks
To catch a glimpse of this celestial beauty, timing and location are crucial. For those in mid-latitude regions, the ideal times to observe zodiacal light are during the evenings in spring and mornings in autumn. Choose a spot far from city lights, under a clear and moonless sky. As twilight fades, lean back, breathe in the fresh evening air, and let your eyes adjust to the darkness.
The sight will often reveal a column of light that appears brighter near the horizon and tilts at an angle parallel to the ecliptic. Often mistaken for a glimpse of the Milky Way, zodiacal light offers a serene reminder of the intricate cosmos we inhabit.
The Connection to Gegenschein
Zodiacal light isn’t the only celestial phenomenon related to interplanetary dust. There’s also the gegenschein, or “counterglow,” which is a faint oval glow seen directly opposite the Sun. This unique aspect of zodiacal light and gegenschein adds depth to our understanding of celestial phenomena and invites us to ponder our place in the universe.
A Cosmic Invitation
Zodiacal light is not just a backdrop for the stars; it represents a beautiful, cosmic connection between our planet and the infinity beyond. It serves as a gentle reminder of the fleeting moments in nature—moments that encourage us to pause, look up, and marvel at the intricate dance of light and dust that swirls around us.
So next time you find yourself under a dark sky, take a moment to seek out this enchanting glow. The zodiacal light is waiting, inviting you to experience the magic of our universe. Happy stargazing!

Benjamin O. Davis Sr.: The General Who Broke the U.S. Military’s Color Barrier
Benjamin O. Davis Sr. rose from the ranks of the Buffalo Soldiers to become the first Black general in U.S. military history. His remarkable career spanned roughly 50 years and helped challenge racial barriers inside a segregated Army.
Forgotten Genius Fridays | STM Daily News
Before the Tuskegee Airmen challenged segregation in the skies over World War II, another barrier was being broken within the ranks of the United States Army.
His name was Benjamin O. Davis Sr.
On October 25, 1940, Davis was promoted to brigadier general, becoming the first African American general officer in the Regular Army and the U.S. armed forces. His promotion represented an extraordinary milestone in a military that was still officially segregated.
But Davis’s story didn’t begin with stars on his shoulders.
It began more than four decades earlier.
From Volunteer to Buffalo Soldier
Born in Washington, D.C., on July 1, 1877, Davis entered military service during the Spanish-American War in 1898, serving as a temporary first lieutenant with the 8th United States Volunteer Infantry.
After that unit was mustered out, Davis made a consequential decision. In June 1899, he enlisted as a private in the Regular Army’s 9th Cavalry Regiment.
The 9th Cavalry was one of the famed Black regiments whose soldiers became widely known as the Buffalo Soldiers.
Davis quickly advanced through the enlisted ranks, becoming a corporal and then squadron sergeant major. In February 1901, he received a commission as a second lieutenant of cavalry in the Regular Army.
His journey through the ranks had begun.
Serving an Army That Wasn’t Equal
Davis would serve his country for decades, but his career unfolded inside an institution constrained by racial segregation.
Assignments available to Black officers were limited, particularly because military practices sought to prevent Black officers from commanding white soldiers. Davis consequently spent portions of his career teaching military science at historically Black institutions, including Wilberforce University and Tuskegee Institute, and served as a military attaché in Liberia.
These assignments were important, but they also reflected the racial restrictions under which Black Army officers served.
Despite those obstacles, Davis continued advancing.
He became a lieutenant colonel in 1920 and a colonel in 1930.
Then came 1940.
A Star That Made History
On October 25, 1940, President Franklin D. Roosevelt promoted Benjamin O. Davis Sr. to brigadier general.
For the first time, a Black officer wore a general’s star in the Regular Army.
The significance extended beyond Davis himself. Black Americans had served in the nation’s armed forces from its earliest conflicts, yet the highest levels of military leadership had remained closed to them.
Davis had broken through that barrier.
Yet the military remained segregated.
Becoming a general did not make segregation disappear.
Instead, Davis would spend part of World War II confronting some of its consequences.
A General Confronts Discrimination
During World War II, Davis served with the Army’s Inspector General organization and undertook assignments involving the conditions and treatment of Black troops.
He traveled extensively, investigated problems affecting soldiers and units, and advised military leaders on matters involving Black servicemen.
His work took him overseas as well. In 1942, he was sent to the European Theater on special duty concerning issues affecting Black troops. He later served in Paris as special assistant to the commanding general of the Communications Zone.
His Distinguished Service Medal citation credited his investigations and advice with helping produce fairer solutions to problems involving soldiers and contributing to broader War Department policy.
Davis therefore occupied an unusual position.
He was simultaneously a senior officer in the United States Army and a Black American serving inside a military whose segregation policies continued to restrict people who looked like him.
Then Came His Son
There is another remarkable dimension to the Benjamin O. Davis story.
While Davis Sr. was breaking barriers within the Army, his son was preparing to break barriers in the air.
Benjamin O. Davis Jr. graduated from the United States Military Academy at West Point in 1936 after enduring years of racial isolation from fellow cadets. He would later become a military pilot and eventually command both the 99th Fighter Squadron and the 332nd Fighter Group, becoming one of the most important leaders associated with the Tuskegee Airmen.
For a period, father and son represented an extraordinary rarity within the U.S. military: two Black career officers operating at a time when opportunities for Black commissioned officers remained severely restricted.
Their stories would eventually become intertwined with one of the most important experiments in American military history.
The Tuskegee Airmen.
Fifty Years of Service
Benjamin O. Davis Sr. retired from active military service on July 14, 1948, completing approximately 50 years of service.
Less than two weeks later, on July 26, President Harry S. Truman issued Executive Order 9981, declaring a policy of equality of treatment and opportunity in the armed services regardless of race, color, religion or national origin.
The transformation of the military would take years.
But Davis had spent much of his career pushing against the barriers that made such a transformation necessary.
He died on November 26, 1970, and was buried at Arlington National Cemetery.
Among his decorations were the Distinguished Service Medal, Bronze Star Medal, France’s Croix de Guerre with Palm, and Liberia’s Order of the Star of Africa.
Why Benjamin O. Davis Sr. Matters
It would be easy to remember Benjamin O. Davis Sr. simply as the first Black general in American military history.
But his significance runs deeper.
He rose from private to general in an institution that placed substantial racial barriers in his path. He served with the Buffalo Soldiers, educated future officers, represented the United States overseas and advised military leaders about the treatment of Black troops during World War II.
And his story became the first chapter of an extraordinary father-and-son legacy.
Benjamin O. Davis Sr. broke one barrier.
His son would soon take the fight into the skies.
Next in our special series: The Tuskegee Airmen — The Red Tails Who Fought Two Wars.
Then, on the following Forgotten Genius Friday, we’ll tell the remarkable story of Benjamin O. Davis Jr.—from four years of isolation at West Point to commanding the Tuskegee Airmen and ultimately wearing four stars.
Forgotten Genius Fridays is an STM Daily News series highlighting innovators, pioneers and historical figures whose achievements deserve a larger place in our collective memory.

John Brown was an American abolitionist who believed slavery would not end through speeches and political compromise alone. Unlike many other white abolitionists of his time, Brown was willing to use armed resistance to fight the institution.
Born in Connecticut in 1800, Brown developed a deep opposition to slavery. He supported the Underground Railroad, assisted people escaping enslavement and worked with Black abolitionists, including Frederick Douglass.
Brown first gained national attention during “Bleeding Kansas,” a violent struggle during the 1850s over whether Kansas would enter the Union as a free or slave state. Brown and his supporters fought pro-slavery forces, and in 1856, his group killed five pro-slavery settlers near Pottawatomie Creek.
His most famous action came on October 16, 1859, when Brown and 21 followers attacked the federal armory at Harpers Ferry, Virginia—now part of West Virginia. Brown planned to seize weapons, distribute them to enslaved people and ignite a widespread rebellion.
The uprising failed to attract the support Brown expected. U.S. Marines, commanded by Col. Robert E. Lee, captured him two days later. Virginia convicted Brown of treason, murder and inciting an enslaved-person rebellion. He was hanged on December 2, 1859.
To some Americans, Brown was a dangerous extremist. To others, he became a martyr who sacrificed his life for freedom. His raid and execution deepened the national conflict over slavery and helped push the United States closer to the Civil War.
John Brown remains one of the most controversial figures in American history—a man whose methods were violent, but whose uncompromising opposition to slavery forced the country to confront an injustice it had long refused to resolve.

The phrase “There’s only one race: human” is simple, hopeful and deeply appealing. It reminds us that beneath differences in skin color, ancestry, nationality and culture, we are members of the same human family.
We share the same basic needs. We want safety, dignity, opportunity, love and a better future for the people we care about. No racial category makes one person more human—or more deserving of respect—than another.
At its best, the phrase rejects the false idea that humanity is divided into separate biological races with different levels of intelligence, character or worth. Those beliefs have been used throughout history to justify slavery, segregation, colonialism and discrimination. Saying that there is only one human race can therefore be a powerful declaration of equality.
But the meaning of the phrase depends on how we use it.
Shared Humanity Does Not Mean Identical Experiences
Although race does not separate people into distinct biological types, racial categories still carry enormous social power. They have shaped laws, neighborhoods, schools, employment, policing, health care and access to wealth. Their consequences do not disappear simply because we say that everyone is human.
That is why “There’s only one race: human” should never become another way of saying, “I don’t see color,” when someone is describing racism or inequality.
Ignoring race does not automatically end racism. In some situations, it can prevent us from recognizing it.
If one group repeatedly encounters barriers that others do not, acknowledging those differences is not an attempt to divide people. It is part of understanding the problem honestly. We cannot repair an injustice that we refuse to see.
Our Differences Are Not the Problem
Human unity does not require sameness. Our cultural identities, traditions, histories and communities are not obstacles that must be erased before we can respect one another.
There is nothing contradictory about celebrating Black history, Latino heritage, Indigenous traditions, Asian American experiences or the many cultures that contribute to our society while also believing in our common humanity.
The problem is not that people have differences. The problem begins when those differences are assigned a hierarchy—when one identity is treated as the standard and another as inferior, threatening or less deserving.
Real unity allows people to bring their complete identities into the room. It does not demand that they leave their histories at the door.
A Statement That Should Lead to Action
If we truly believe there is only one human race, that belief should influence how we treat people. It should lead us to oppose discrimination even when we are not its target. It should make us question stereotypes, listen to experiences different from our own and defend the dignity of people whose backgrounds we may not fully understand.
Shared humanity is more than a comforting slogan. It is a responsibility.
It asks us to recognize that another person’s pain matters, even when it is unfamiliar to us. It reminds us that no community is disposable and that injustice against one group ultimately damages the society we all share.
One Human Family, Many Human Stories
To me, “There’s only one race: human” is most meaningful when it brings two truths together: we are fundamentally equal, and we do not all experience the world in the same way.
We can affirm that there is one human family without pretending racism has disappeared. We can value what connects us without erasing what makes our communities distinct. We can pursue unity while still confronting the inequalities that stand in its way.
Perhaps the fullest version of the message is this:
We are one human family. Our differences deserve respect, our histories deserve acknowledgment, and every person deserves equal dignity.
That is not merely an ideal. It is a standard by which we can judge our choices, our institutions and the kind of world we are building together.
