How an amateur astronomer captured a black hole scoopA personal narrative is presented that discusses an amateur astronomer's imaging of and discoveries about the Cygnus X-1 black hole.Cullen, Step...
However, another astronomer named Heber Curtis argued that spiral nebulae were merely part of the Milky Way. The debate raged on for years because astronomers needed larger, more powerful, telescopes to resolve the details. 21st-century Innovations In 1924, Edwin Hubble settled the debate. He ...
When you have a small aperture scope (like I do), traveling to a really good dark site will make a world of difference, especially for DSO's. Fainter objects suddenly become visible, and showpiece objects become a lot more interesting. And then there's the Milky Way. The trick is how ...
In the 10th century, Persian astronomer (and astrolabe adorer) Abd al-Rahman al-Sufi wrote a book claiming 1,000 uses for an astrolabe. The Persian may have been exaggerating slightly, but in the hands of a skilled practitioner, the instrument could provide answers to many problems. With an...
red giant. The radius of the red giant sun will be just beyond Earth's orbit. At some point after this, the core will become hot enough to cause the helium to fuse into carbon. When the helium fuel runs out, the core will expand and cool. The upper layers will expand and eject mat...
And I, I regret to say that it’s starting to become a software problem. Fraser Cain [00:22:36] Right. Pamela Gay [00:22:37] Yeah. So there are currently satellites crossing the sky in almost every direction, not literally every direction, because going against the rotation of the ...
and it’s a good idea to go through the process during the daytime, when the light is at its best. Don’t attempt to assemble your scope outside at night; not only is it difficult to read and see what you’re doing, but if you drop a part on the ground it can become easily lo...
s not looking for purchasing advice but how to enjoy the scope he now has. Rather than coming up with a plan in advance, I suggest you ask him about his interests and goals for this scope and then see how you can help him achieve those goals. If he is able to become successful, ...
a piece of 1960s rocket debris joined us brieflybefore heading off to orbit the sun, and in 2022, an amateur astronomer discovered2022 NX1,an asteroid orbiting earth for a month. Long-capture episodes, where an object pairs up with us for at least one complete orbital revolution, are less...
Today, the Schmidt-Cassegrain design, which was invented in the 1960s, is the most popular type of telescope; it uses a secondary mirror that bounces light through a hole in the primary mirror to an eyepiece. The second type of compound telescope was invented by a Russian astronomer, D. ...
