Space telescopes as a research area encompass the scientific and technical study, design, deployment, and utilization of astronomical observatories operating above Earth’s atmosphere to access wide spectral ranges (e.g., ultraviolet, X-ray, gamma-ray, infrared) and achieve high-precision photometry, spectroscopy, and imaging. The field addresses orbital dynamics, thermal and structural stability, detector and optics optimization, contamination control, and data calibration pipelines. Research includes mission architecture, survey strategies, multi-messenger and time-domain coordination, and methodologies for extracting cosmological, stellar, and planetary parameters from space-based observations, as well as technology development for next-generation observatories and constellations.
A two-armed space robot blasted off on a private salvage operation Tuesday to slap life-extending jetpacks on old satellites running low on fuel thousands of miles up.

Dreams of finding a sort of Earth 2.0 motivate much of the thinking around the search for exoplanets. But there is more to exoplanet science than searching for potentially habitable worlds. Scientists need a deeper understanding ...

Are we alone in the universe? For scientists working on NASA's proposed Habitable Worlds Observatory, that question is no longer purely philosophical. It is increasingly becoming an engineering problem.

Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quickly is key to understanding ...

A team of astronomers has discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b—the first planet discovered in the same system—and is among the ...

How do black holes at the centers of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances that existed much earlier in the universe's history. ...

The massive globular star cluster Omega Centauri has puzzled astronomers for decades. It should be filled with black holes left behind by exploding stars, yet evidence for them is scarce. Now, astronomers using archival data ...

We've talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using current rocket fairings—at least as long as we're not sending them 500-plus AU away to a gravitational ...
