We report on the observation and measurement of astrometry, photometry, morphology, and activity of the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS), with the NSF-DOE Vera C. Rubin Observatory.
A baby planet is shrinking from the size of Jupiter with a thick atmosphere to a small, barren world, according to a new study from NASA’s Chandra X-ray Observatory.
The Decadal Survey on Astronomy and Astrophysics 2020 highlights the importance of advancing research focused on discovering and characterizing habitable worlds.
The instrument payload of the future Habitable Worlds Observatory (HWO) will span a wide range of wavelengths, including the ultraviolet (UV) region that cannot be easily accessed from the ground […]
The current state-of-the-art cosmic distance ladder requires three rungs–geometric distances, primary indicators, and Type Ia Supernovae–to achieve a 1% measurement of the Hubble constant H0.
Since the discovery of the first exoplanet orbiting a Sun-like star, the confirmation of nearly 6000 exoplanets to date – and their diversity – has revolutionized our knowledge of planetary […]
Are there planets similar to Earth? Do they orbit stars like our Sun? How do planetary systems form and evolve? To answer these and other questions, the European Space Agency […]
The primary scientific objective of this Habitable Worlds Observatory (HWO) Science Case Development Document (SCDD) is to measure planetary rotation rates of transiting exoplanets to determine the structure, composition, circulation, […]
NASA’s Habitable Worlds Observatory (HWO) will be the first space telescope capable of directly imaging Earth-like planets in the habitable zones of Sun-like stars to probe their atmospheres for signs […]
We have surveyed all conventional methods proposed or conceivable for obtaining resolved images of an Earth-like exoplanet.
