What is ephemeris in astronomy?The Study of Celestial Objects:Astronomy is the science that involves the study of various celestial objects, like the planets, the Sun, stars, galaxies, asteroids and possible distant solar systems. Astronomers study how these objects came into being and their ...
What is phenomenology in astronomy? Astronomy Astronomy is the study of space, especially outside of Earth. Since objects in space have matter and are capable of movement, an understanding of physics is used in astronomy. The laws and theories of physics apply to astronomy. ...

This region’s balanced metallicity is key for forming rocky planets like Earth. Metals, which in astronomy refer to all elements heavier than hydrogen and helium, are crucial building blocks. They are forged in the hearts of massive stars and dispersed across the galaxy through supernova ...
—Strange anomaly in sun's solar cycle discovered in centuries-old texts from Korea —Famous astronomers: How these scientists shaped astronomy The oldest alleged calendar is a carving found on an ivory mammoth tusk, dated to an astonishing 30000 B.C. While there is debate about what the car...
Perhaps the most novel term in the lunar calendar is "gibbous," which broadly means convex, but in astronomy specifically refers to the time when the moon is more than half but not wholly illuminated. Let's look at an entire lunar cycle by going into detail about the lunar phases. There...
mechanism involves a great deal of mass, then the only astronomical object that can confine a lot of mass into a very small space is a black hole. In a few cases, it turns out that the X-rays are emitted from a region just a few times the size of the black hole event horizon. ...
"The event horizon is the ultimate prison wall — one can get in but never get out," Avi Loeb, chair of astronomy at Harvard University, told Space.com. When an item gets near an event horizon, a witness would see the item's image redden and dim as gravity distorted light coming from...
What a year! - posted in General Observing and Astronomy: Ive been looking up since my childhood. Over the years I have always made the effort to observe any astronomical event within reach between New York, Florida, and now Missouri. My first solar ecli
