Johns Hopkins applied mathematicians and astronomers have developed a new method to render images from ground-based telescopes as clear as those taken from space, a process that stands to expand the benefits of Earth-based instruments.

Young asteroids—which formed much later than those that were created during the formation of our solar system—are typically created when larger asteroids, planetesimals, or comets collide and break up into smaller pieces. These smaller pieces form “asteroid families” that share certain properties, like their semimajor axis, eccentricity, and inclination—all of which describe their orbital paths. […]

Slices from the edge of Mars reveal a layered atmosphere of delicate complexity. A European spacecraft has captured a luminous mille-feuille of dust enveloping the red planet in unprecedented detail.

Growing evidence suggests that a subsurface ocean lurks beneath the icy surface of Uranus’ moon Ariel, but new research, published in Icarus, characterizes the possible evolution of this ocean, and found that it may have once been over 100 miles (170 kilometers) deep. For perspective, the Pacific Ocean averages 2.5 miles (4 kilometers) deep.

The SOAR Telescope, located on Cerro Pachón in Chile, has received a major upgrade with the installation of the SOAR Telescope Echelle Spectrograph (STELES). The long-awaited instrument achieved first light in August with observations of the binary star system Eta Carinae, along with 13 other targets. SOAR is part of U.S. National Science Foundation Cerro […]

A recent Physical Review Letters study presents a new model for quark star merger ejecta that could resolve whether these cosmic collisions generate ordinary matter or something different.
