‘A watershed in furthering our understanding of these structures,’ researcher says. An unprecedented new telescope image of the Milky Way galaxy’s turbulent center has revealed…
An international team of researchers, led by postgraduate student Alexis Andrés, has found that the black hole at the center of our galaxy, Sagittarius A*,…
New treasure trove of globular clusters holds clues about galaxy evolution. Using observations of the nearby elliptical galaxy Centaurus A, a team of astronomers led…
98.5% of the Sun is made up of two light chemical elements, hydrogen and helium, while the remaining 1.5% consists of other heavier elements such…
One of the characteristic features of modern cosmology is its description of how galaxies evolve: via a hierarchical process of colliding and merging with other…
An international team of astronomers, led by researcher Chervin Laporte of the Institute of Cosmos Sciences of the University of Barcelona (ICCUB-IEEC), has used data…
For the first time, astronomers have detected a newborn star and the surrounding cocoon of complex organic molecules at the edge of our Galaxy, which…

Astronomers at The University of Texas at Austin’s McDonald Observatory have discovered an unusually massive black hole at the heart of one of the Milky…
The center of the Milky Way is a mysterious place. Astronomers think there’s a supermassive black hole there, though it could be dark matter instead….
Webb will tackle the challenge of the supermassive black hole’s puzzling flares, which have proved both intriguing and frustrating for astronomers. In its first year…
Around a century ago, scientists began to realize that some of the radiation we detect in Earth’s atmosphere is not local in origin. This eventually…
In early 2020, we detected an unusual radio signal coming from somewhere near the center of our galaxy. The signal blinked on and off, growing…
NASA has selected a new space telescope proposal that will study the recent history of star birth, star death, and the formation of chemical elements…
