Hello friends. For a while now, I've been wanting to write about the stages of development and evolution of the universe, from the Big Bang to the present day. In preparing this article, I'll cover a total of 10 stages in two parts. After these two parts are completed, I'll write a separate article about the projected future of our universe, and finally, a more detailed article about the Big Bang. The article, titled "Timeline of the Universe," […]
The Butterfly Star Cluster, also known as M6 or NGC 6405, lies 2,000 light-years away and is 20 light-years across. Visible even with binoculars—in a location free of light pollution—the Butterfly Star Cluster is located toward the constellation Scorpius. Blue stars indicate young stars, while orange stars indicate the brightest stars. [...]
The title sounds a bit like the name of a selfie, doesn't it? Anyway... How do you think this picture was taken? Usually, spacecraft are photographed from the International Space Station. The International Space Station is photographed from a spacecraft. But how can you explain the two being in the same frame?
Feynman's lectures are among the most famous in the world of physics. They are fantastic and useful for students, teachers, enthusiasts, scientists—in short, everyone. The California Institute of Technology (Caltech) has published the entirety of the lectures online for free on its Feynman Lectures website. These lectures were originally presented by physicist Richard Feynman at Caltech in 1960. Now, they have been compiled and published in three parts […]
The beautiful Trifid Nebula, also known as Messier 20, is located in the Sagittarius region, the central region of our galaxy rich in nebulae. It can be easily found and observed even with a small telescope. It is 5,000 light-years away. In the upper right corner, you can see the open star cluster known as Messier 21. The Trifid Nebula is 40 light-years across and 300,000 years old. […]
The Tadpole Galaxy, also known as Arp 188, is a fragmented barred spiral galaxy located 400 million light-years from Earth toward the northern constellation Draco. Its most dramatic feature is a trail of bright blue star clusters 280 thousand light-years long, called the Tadpole Tail. A larger galaxy is thought to pass near the Tadpole Galaxy (from Earth's perspective, left to right), and […]
