Massive galaxies in the early Universe should have contained large amounts of cold molecular gas, the fuel required to make stars. But new observations...
The intermediate-mass black hole in question was caught in the act of swallowing a star, called a tidal disruption event. Dubbed 3XMM J215022.4-055108,...
Using spectral data from the Sloan Digital Sky Survey (SDSS), the Chandra Source Catalog 2.0, and the Chandra COSMOS Legacy survey, astronomers have found...
Astronomers using the NASA/ESA Hubble Space Telescope have measured the metallicity of the neutral interstellar medium towards 25 bright stars in our Milky...
Ultradiffuse galaxies are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low brightness, making them very difficult...
By combining gravitational lensing with the capabilities of NASA’s Chandra X-ray Observatory, astronomers have detected two X-ray-emitting objects —...
In a new theoretical paper, researchers from the Santa Fe Institute provide a new perspective on the origin of life by arguing that life has emerged many...
Astronomers using CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP) telescope, a radio telescope situated about 800 km north of Perth, in...
Astronomers using data from NASA’s Spitzer Space Telescope have looked for dust-extinguished supernovae in the nuclear regions of 40 luminous and ultra-luminous...
Black holes are famously compact objects where the paths of light are drastically bent by the curvature of space-time. While light itself cannot escape...
Astronomers using NSF’s Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States and by the Virgo detector in Italy have observed...
Singularities play an interesting role in physics, and come in many different varieties, from the mathematically and philosophically challenging to the...
A team of astronomers from the United Kingdom and the United States has examined six of the most distant galaxies currently known and found that the distance...
Astrophysical observations show that supermassive black holes exist when the Universe is just 800 million years old after the Big Bang (just 6% of its...
In a new study, astronomers used data from the NASA/ESA Hubble Space Telescope to calculate a more accurate distance to an ultra-diffuse galaxy called...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected a galactic-scale supermassive black hole-driven wind in HSC J124353.93+010038.5...
An international team of astronomers from the United States and the United Kingdom has made the discovery of a giant, almost symmetrical arc of galaxies...
Cosmic filaments are cylindrical tendrils of matter hundreds of millions of light-years across. In new research, published in the journal Nature Astronomy,...
