Using the radiation signatures of quasars, scientists have determined when the era of reionization ended in our universe – about 1.1 billion years after the Big Bang.

Jun 14th: Found: Dying Galaxies Containing Active Black Holes
Astronomers combined observations of far distant galaxies exhibiting no signs of star formation and found active supermassive black holes that may have contributed to the evolution of their parent galaxies. Plus, rocket launches, detecting earthquakes, and why Uranus and Neptune are different shades of blue.
Jun 8th: Pulsars as the Particle Accelerators of the Universe
Fast, strong magnetic winds caused by quickly rotating pulsars may be accelerating particles like electrons to extremely high-energy states and creating gamma-ray photons in their wake.
May 31st: Chaos Reigned Ian The Early Solar System
Researchers using radioactive decay analysis have recreated the early history of some asteroids in our solar system, revealing a more chaotic phase than previously thought
May 26th: Supernova Evidence Found In Comet Fragment
A forensic analysis of the element concentration found in the Hypatia stone finds evidence in the cometary fragment, which may have impacted Earth 28 million years ago, of a supernova origin story
May 11th: Newly Found ‘Black Widow’ Binary Has Third Companion
The flash of a pulsar about 3,000 light-years from our solar system was caused by a ‘black widow’ binary consuming a smaller star. Intriguingly, a third companion star is orbiting the pair, which may have originated near the Milky Way’s center.
Apr 30th: An In-Depth Look at Recent Mars Science And Exploration
A new paper looks at marsquakes and what is causing them, which turns out to be magma moving. And Curiosity has found rocks it needs to go around. Then there is the weather on Mars
Apr 13th: Hubble Finds Farthest Star Ever Spotted
Researchers pouring through high-resolution Hubble images of galaxy clusters have found the gravitationally magnified light of a star that was shining just four billion years after the Big Bang, making this bright star the new record holder for the farthest ever spotted
Apr 7th: More From ESA’s Gaia: Weird White Dwarf News
Researchers use data from ESA’s Gaia telescope to discover that white dwarf stars have two different distributions both in how they move and how bright they shine.
Mar 29th: Using the Moon to Detect Time-Space Changes
Scientists propose using changes in the distance from the Earth to the Moon and measured by lasers as a way to detect the phenomenon of gravitational waves. Plus, JWST is working, ExoMars is at risk.
