The question of how small, dwarf galaxies have sustained the formation of new stars over the course of the Universe has long confounded the world’s astronomers. Now, an international research team has found that dormant small galaxies can slowly accumulate gas over many billions of years. When this gas suddenly […]

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The galaxy is so far away its light has taken more than 12 billion years […]

On July 4, NASA’s Transiting Exoplanet Survey Satellite (TESS) finished its primary mission, imaging about 75% of the starry sky as part of a two-year-long survey. In capturing this giant mosaic, TESS has found 66 new exoplanets, or worlds beyond our solar system, as well as nearly 2,100 candidates astronomers […]

Using the Australian Square Kilometer Array Pathfinder (ASKAP), astronomers have performed observations of a cluster of galaxies known as SPT-CL J2032−5627. They identified two radio relics that could improve our knowledge about this cluster. The finding is reported in a paper published August 3 on arXiv.org.

John-David Bartoe was having none of it.

Space fans of all political persuasions should care that Joe Biden just picked Sen. Kamala Harris (D-Calif.) as his running mate.

The annual Perseid meteor shower, one of the best “shooting star” displays of the year, peaks overnight tonight (Aug. 11-12). Skywatchers with clear, dark skies can expect to see about 60 meteors per hour. 

New 2-D and 3-D computer modeling of impacts on the asteroid Psyche, the largest Main Belt asteroid, indicate it is probably metallic and porous in composition, something like a flying cosmic rubble pile. Knowing this will be critical to NASA’s forthcoming asteroid mission, Psyche: Journey to a Metal World, that […]

Astronomers have applied artificial intelligence (AI) to ultra-wide field-of-view images of the distant Universe captured by the Subaru Telescope, and have achieved a very high accuracy for finding and classifying spiral galaxies in those images. This technique, in combination with citizen science, is expected to yield further discoveries in the […]
