3D Printing Is Becoming Unstoppable
3D printing opened the door to many people to create whatever they wished. In the beginning, most items were created with plastics, but that’s no longer the case and other elements can be printed. It is now possible to even print human cells.
Who knows what might be possible in the next few years, but it’s clear that we could see major developments in cell research.

Star Forming Region NGC 3582 without Stars
What's happening in the Statue of Liberty nebula? Bright stars and interesting molecules are forming and being liberated. The complex nebula resides in the star forming region called RCW 57, and besides the iconic monument, to some looks like a flying superhero or a weeping angel. By digitally removing the stars, this re-assigned color image showcases dense knots of dark interstellar dust, fields of glowing hydrogen gas ionized by these stars, and great loops of gas expelled by dying stars. A detailed study of NGC 3576, also known as NGC 3582 and NGC 3584, uncovered at least 33 massive stars in the end stages of formation, and the clear presence of the complex carbon molecules known as polycyclic aromatic hydrocarbons (PAHs). PAHs are thought to be created in the cooling gas of star forming regions, and their development in the Sun's formation nebula five billion years ago may have been an important step in the development of life on Earth.

ARLINGTON, Va – ARLINGTON, Va. - Every branch of the armed forces has an official song, from "The Army Goes Rolling Along" to "The Marines' Hymn." Each song is part of the services' foundation and represents its values, traditions and culture.
The U.S. Space Force, the newest military branch established in 2019, has officially adopted its own song titled "Semper Supra" that was unveiled during the 2022 Air & Space Forces Association Air, Space and Cyber Conference in National Harbor, Maryland, Sept. 20.
“Semper Supra" was named after the USSF motto, which is Latin for "Always Above." It was created to capture the esprit de corps of both current and future Guardians, and intends to bring together service members by giving them a sense of pride.
Two former service members collaborated to create the song, a process that took years of research and revisions to make sure the song was ready for release.
"The song was a long work in progress because I wanted it to encompass all the capabilities that the Space Force offers and its vision," said James Teachenor, a singer/songwriter who created the lyrics and melody; was the visionary composer and driving force of the song's creation.
Teachenor, a prior member of the U.S. Air Force band at the Air Force Academy, worked with Chief of Space Operations Gen. John "Jay" Raymond to begin the songwriting process when the Space Force was formed in 2019.
"This is a once-in-a-lifetime opportunity to establish a Space Force song that will be part of our culture and heritage for years to come," Raymond said. "Our traditions are part of the fabric that weave us all together as we execute our missions side-by-side; I will be proud to sing 'Semper Supra' alongside my fellow Guardians."
After creating a foundation for the song, Teachenor's project was sent to various military bands that could create a musical arrangement to give finishing touches and complete the song's sound; 12 musical submissions of the song were under review. Teachenor then collaborated with chief musician Sean Nelson, U.S. Coast Guard Band trombonist and staff arranger.
"I received the melody and words from James, and he wanted me to help add the harmony and to orchestrate it," said Nelson. "At first, it started with singing and the piano. I became familiar with the other branches' songs, but I wanted this one to have its own modern spin to reflect what the Space Force is - modern, new and very advanced."
Once Nelson added more than 30 instrument parts, the song's arrangement was played and recorded by the USCG band, then submitted to the Space Force for review. After many months of development, revisions and variations in coordination with the USCG band, the Space Force picked the final version of
"Semper Supra," to capture what it means to be a Guardian.

SEMPER SUPRA
The Official U.S. Space Force Song
We're the mighty watchful eye,
Guardians beyond the blue,
The invisible front line,
Warfighters brave and true.
Boldly reaching into space,
There's no limit to our sky.
Standing guard both night and day,
We're the Space Force from on high.
