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.
NASA's SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) mission has mapped interstellar ice at an unprecedented scale. Covering regions in our Milky Way galaxy more than ...

Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have observed a giant exoplanet known as HATS-75 b. Results of the new observations, published April 8 on the arXiv ...
The Subaru Telescope observed the interstellar comet 3I/ATLAS on January 7, 2026, after it made its closest approach to the sun. By observing colors in the coma around the comet, astronomers could estimate the ratio of carbon ...

Gamma-ray bursts (GRBs) rank among the most powerful explosions in the universe, releasing immense energy in intense flashes of gamma rays. The most distant GRBs originate from the era when the first stars and galaxies formed. ...

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way.

Designed to hunt for new alien worlds, NASA's Transiting Exoplanet Survey Satellite (TESS) has serendipitously observed the rising outburst of a black hole X-ray binary known as AT 2019wey. The observations, which may help ...
We're getting closer and closer to finding a real Earth-like exoplanet. But finding one is only half the battle. To truly know if we're looking at an Earth analog somewhere else in the galaxy, we have to directly image it ...
