This all-inclusive refractor is best for observing planets and the moon, but still able to give skywatchers some glimpses of deep-sky objects.

Optical aberration theory remains a fundamental component in the design and operation of space telescopes. With increasingly ambitious astronomical missions and the demand for high-resolution imaging, ...

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

“They can move in steps that are a fraction of a wavelength of light, or about 1/10,000th the diameter of a human hair,” explained Lee Feinberg, optical telescope element manager of the NASA James ...

Upon arrival at NASA's Goddard Space Flight Center, the Optical Telescope Assembly for the agency's Nancy Grace Roman Space Telescope was lifted out of the shipping fixture and placed with other ...

A team of astronomers from the U.S. Naval Observatory (USNO), Naval Research Laboratory (NRL) and the European Southern Observatory (ESO) have successfully used the ultra high-resolution capability of ...

Welcome to the Tuesday Telescope. There is a little too much darkness in this world and not enough light—a little too much pseudoscience and not enough science. We'll let other publications offer you ...

ROCHESTER, N.Y. (WROC) – L3Harris has recently delivered the Rochester built Optical Telescope Assembly to NASA, reaching a big milestone on the Nancy Grace Roman Space Telescope program. The 7.9-foot ...

More and more papers are coming out about the upcoming Habitable Worlds Observatory (HWO). As the telescope moves from theory to practice (and physical manifestation), various working groups are ...

Flagstaff, Ariz. – Lowell Observatory and the University of Arizona’s College of Optical Sciences (OSC) have finalized a $3 million, three-year contract to complete the Discovery Channel Telescope ...
