题目Telescopes(望远镜)have come a long way since the first ones were invented early in the 17th century.Traditional telescopes allow astronomers to view objects in space thanks to the visible(看得见的)light those objects emit(发出),or reflect.However,for modern telescopes,any Electrom...

Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA’s Goddard Space Flight Center in Maryland. ...
Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a different angle (角度). These two telescopes act like Gaia’s “eyes”. The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly differ...
The LAMOST survey, capable of taking 4,000 spectra in a single exposure, has released spectra for more than 10 million stars, approximately 220,000 galaxies, and some 71,000 quasars, twice as large as the spectra obtained from other ground-based sky survey telescopes put together. ...

However, amateurs span the range from so-called "armchair astronomers" to the very ambitious, who own science-grade telescopes and instruments with which they are able to make their own discoveries and assist professional astronomers in research. This text uses material from Wikipedia, licensed ...
in Space. She worked with a group of scientists at SETI to come up with a secret message. Last Wednesday, the European Space Agency’s ExoMars Trace Gas Orbiter spacecraft sent the coded message back to Earth from Mars. The signal was picked up by several radio telescopes around the ...
Whether you want to glimpse the last full moon of the year on Dec. 15 in extraordinary detail or watch the Ursids Meteor Shower on Dec. 21, it's important to pair one of the best telescopes with an equally capable laptop – especially if you are observing on the move. A great laptop...
"Adaptive optics and guide stars are really meant to allow you to get the full angular resolution capabilities of the big ground-based telescopes; in space, we are taking advantage of our access to wavelengths that, from Earth, are 'blocked' by the atmosphere." 机译:从哈勃的“谦虚”开始...
