Current millimeter telescopes can only just detect the most luminous sources, giving us tantalizing first glimpses of the epoch of galaxy formation. A very large millimeter telescope is now required to explore these new horizons, one with both high sensitivity and angular resolution - The Atacama ...
The dusty red planet has fascinated us for centuries. Even as we learn more, its mysteries keep us in suspense.
Why can radio telescopes be used 24 hours a day? How does an optical telescope capture information? Why are many large optical telescope located on mountaintops? What are the primary reasons for making telescopes larger? When was the first radio telescope invented? Why is the James Webb Space ...
Why are most large telescopes reflectors not refractors? Why are there only gas planets beyond the asteroid belt? Why aren't there comets in the asteroid belt? Why does a larger telescope allow astronomers to see more? Why does Venus have no moons? Why are many large optical telescope loca...
But so far, sweeps of the sky with Earth-based telescopes for signals that might be beacons from distant civilizations have proven fruitless, possibly because the Earth's atmosphere interferes with such messages reaching us. That's why searchers for extraterrestrial civilizations are eager for the ...
Why Is Space Cold If There Are So Many Stars? A Finite Universe When the most powerful telescopes every made gaze out into the vastness of space, they are essentially looking back in time. We are able to see 46 billion light-years in every direction, while any light source beyond that ...
China also wants to use a moon base as thebasis of a telescopic array. Telescopic arrays are a collection of ground-based or orbital telescopes. They work together over time to produce the same image as a telescope of their collective scope. The most common example of this is theVery La...
If large telescopes, NASA satellites, and complicated mathematical data analysis are involved, it becomes harder for outside observers to mistake the work for the ramblings of UFO‐nuts and other crackpots. There may be no signals from space, yet those with their antennas tuned to more ...
They play important roles in galaxies, perhaps even in the large-scale behavior of the universe and more. The other thing to note about black holes is that they are very ‘simple’ especially when compared to stars and other astrophysical objects. This is a consequence of the so-called ‘...
Why are the cornea and sclera different? How does refractive index affect focal length? Why is radioactive pollution so harmful? Why do animals' eyes reflect light? What are some effects of visual pollution? What are the advantages and disadvantages of radio telescopes? What are some causes of...
