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.
