500,000 satellites from SpaceX's FCC filing, two published brightness models and the real stars, for any latitude, date and time. Computed in your browser.

We present high signal-to-noise, medium resolution (R ~ 1000), time-series JWST/NIRSpec spectra of WISE 0855 (265K), the coldest known brown dwarf. Medium resolution, time-series spectroscopy gives us...

Without drastic interventions, data centers in space could disrupt scientific observations and fragile ecosystems by adding almost innumerable new “stars” to the heavens above

Springer Nature has removed two studies by Max Planck. A bot may be to blame

Unexpected shift in funds has meant sharp drop in grants this fiscal year

The Kepler mission and its follow-on K2 discovered thousands of exoplanets around different types of stars, and new work reveals broader trends in the planetary populations of the Milky Way.

With recent advances in exoplanet observational techniques enabling the discovery of increasingly smaller planets, a crucial question emerges in the search for habitable planets: how small can a plane...

From the onset of observations of JWST we have discovered unexpectedly luminous galaxies at redshifts $z>10$ and as high as $z=14$. With their discovery, the question immediately followed as to where ...

We report observations of stripe-like features in Enceladus' plumes captured simultaneously by Cassini's VIMS-IR and ISS NAC instruments during flyby E17, with similar patterns seen in VIMS-IR data fr...

NASA's Transiting Exoplanet Survey Satellite (TESS) has identified thousands of exoplanet candidates, yet many remain unconfirmed due to the limitations of manual vetting processes. This paper present...

On April 17, engineers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California sent commands to shut down an instrument aboard Voyager 1 called the
