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.
While it may appear as just another spiral galaxy among billions in the universe, this image from the NASA/ESA Hubble Space Telescope reveals a galaxy with plenty to study. The galaxy, NGC 7456, is located over 51 million ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two rocky exoplanets orbiting a nearby K-type star, known as TOI-2322. The newfound alien worlds are comparable in size to Earth and have ...
What was the universe like in the first few hundreds of millions of years after it came into existence? How did the first stars and galaxies form? Those are questions that astronomers now have a better chance of answering, ...

Sometimes in science a negative result is just as important as a positive one. And sometimes data artifacts get the better of even the best space observatories. Both of those ideas seem to hold true for the James Webb Space ...
