Why is X-ray astronomy done with telescopes in space? Why are there no seasons on Jupiter? Why is a light-year a more useful measurement in astronomy than a meter is? Why are terrestrial planets close to the Sun? Why do people study the Oort cloud?
Why is X-ray astronomy done with telescopes in space? Why is the Hubble Space Telescope being replaced? Why is Saturn yellow? Why was the Galileo space probe destroyed? Why are many large optical telescope located on mountaintops? Why won't 'Oumuamua orbit the sun?

Packing a double punch of observational power, NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton space telescope have been observing Sgr A* (pronounced "Sagittarius A-star") on and off since 1999. In the last three years, the total coverage time has increased thank...
Visual, radio, and x-ray telescopes collect information from across the entire spectrum of electromagnetic waves; computers handle data and complicated computations to interpret them; space probes send back data and materials from remote parts of the solar system; and accelerators give subatomic ...
I live in a Bortle-9 location and tend to prefer smaller exit pupils, around 2mm for my scopes, 2.5mm for my binocular telescopes (i.e. BT's) and around 3mm for my straight-through binoculars. I don't have any 5mm binoculars. (The only one I have, the Nikon WX 10x50, has b...
they do tend to come down on the robot side of the coin, because they tend to perceive that they could be doing lots more interesting things in the solar system in terms of space probes and telescopes and things like that if all this money wasn’t wasted on things like space shuttles ...
“we could have blown the discovery of the century”—a 2017 neutron star collision that, unlike the 2015 black hole collision, wasalso studiedby radio, gamma-ray, x-ray, and visible-light telescopes. That was made possible only because LIGO and Virgo shared data, allowing them to quickly ...
missed from the defense force. One man reflected: "I found a lot of Australian soldiers that are lost. You think you're a civilian but you're not, you never will be […] even three years' service in the army will change you forever. And the Australian government doesn't do enough....
But this is just the first move in what must be a vigorous debate. And in that debate, surveys like these (interesting as they are) can play only a limited role. How good is our first judgement? Machines are much faster than us; they don't panic. At their best, they might embody ...
