The article discusses how the discovery of a nebula by amateur astronomer Jay McNeil changed the science of stellar astrophysics. Topics include an overview of the link between star formation and X-ray ...
In one case, the first author on the paper is one of the people that I’ve worked with through Swinburn Astronomy Online, who’s an amateur astronomer who’s been taking some online classes to work to get an advanced degree in this thing he does as a hobby. You ...
In 1912, Danish astronomer Ejnar Hertzsprung and American astronomer Henry Norris Russell independently graphed the luminosity vs. temperatures for thousands of stars and found a surprising relationship as shown below. This diagram called aHertsprung-Russell or H-R diagramrevealed that most of the sta...
Major decisions are forthcoming on how to create the infrastructure needifEarth's celestial partner is to become a major thoroughfare and keep up any long-term human habitation there. You may like There are 3 private lunar landers headed to the moon right now — a 1st in space history China...
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 ...
But that’s not the best place to see it. Ideally, your goal should be to stand beneath the Moon’s darker, inner shadow — the umbra. That’s where day will turn into night, where several planets will become visible, and where the corona — the Sun’s normally invisible outer ...
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 ...
A throne bearing a ring sat above the noon marking, defining the top of the astrolabe and providing an attachment point. When he wanted to use the instrument, an astronomer would tie a rope through the ring and let the device hang straight down. Plates Next came a series of plates, with...
Amateur astronomer Ralf Vandebergh, also of the Netherlands, used a 10-inchreflector telescopeequipped with a camera to photograph the ATV-3 Edoardo Amaldi in orbit. His photos show a hulking cylindrical spacecraft with its solar arrays unfurled as it chases the International Space Station. ...
Come back to Jupiter a few hours later (or the next night) to see how the positions of the moons have changed. As you become more experienced, you’ll be able to watch as the moons cast shadows upon the planet, disappear behind the world and then reappear as they emerge from out of...
