Study led by a University of Oregon physicist reconfigures a distance-calculation technique built around empirical observations. Using known distances of 50 galaxies from Earth to…
An international consortium of scientists has analyzed, as part of a vast program of cosmological surveys, several million galaxies and quasars, thus retracing a more…
Study suggests the rare objects likely came from an early planetesimal with a magnetic core. Most meteorites that have landed on Earth are fragments of…
When it launches in the mid-2020s, NASA’s Nancy Grace Roman Space Telescope will create enormous panoramic pictures of space in unprecedented detail. The mission’s wide…
This image shows the huge extent of a spiral galaxy’s magnetic field. The galaxy NGC 4217 is a star-forming, spiral galaxy, similar to our own…
For just the second time ever, astrophysicists have spotted a spectacular flash of ultraviolet (UV) light accompanying a white dwarf explosion. An extremely rare type…
Gravitational waves are ripples in space-time that come in many forms. So far, short-duration gravitational wave signals have been observed from colliding black holes and…
The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has taken the first-ever image of a young, Sun-like star accompanied by two giant exoplanets. Images…
New Cosmic Magnetic Field Structures Discovered in Galaxy NGC 4217 Superbubbles, giant loops and X-shaped magnetic field structures – this galaxy boasts a veritable wealth…
The unusual dark greenish and glistening “gel-like” substance in a crater on the far side of the moon has attracted widespread interest following its discovery…
The Sloan Digital Sky Survey (SDSS) released a comprehensive analysis of the largest three-dimensional map of the Universe ever created, filling in the most significant…
The telltale sign that the black hole was feeding vanished, perhaps when a star interrupted the feast. The event could lend new insight into these…
Many exoplanets known today are ‘super-Earths,’ with a radius 1.3 times that of Earth, and ‘mini-Neptunes,’ with 2.4 Earth radii. Mini-Neptunes, which are less dense,…
The second most distant quasar ever discovered now has a Hawaiian name. Astronomers have discovered the second most distant quasar ever found, using the international…
Michael Troxel has always liked puzzles, especially challenging ones. Which is fortunate, since his job is solving some of the most perplexing, fundamental mysteries of…
Scientists have found the interstellar organic matter could produce an abundant supply of water by heating, suggesting that organic matter could be the source of terrestrial water….
A simple model explains a wide range of observations by describing a contest between galaxy halos and their central black holes that eventually turns off…
