A "classification" is when a volunteer or citizen scientist finishes marking up or sorting one image or other piece of data. Each classification done by volunteers for the Redshift Wrangler project tells us something about ...
Astronomers have discovered strong evidence for the closest supermassive black hole outside of the Milky Way galaxy. This giant black hole is located in the Large Magellanic Cloud, one of the nearest galactic neighbors to ...
Interstellar material has been discovered in our solar system, but researchers continue to hunt for where it came from and how it got here. A new study led by Western astrophysicists Cole Gregg and Paul Wiegert recommends ...
Rolf Landauer showed that "information is physical" with every bit equivalent to a small amount of energy proportional to temperature. The Landauer equivalent energy of information carried, or represented by matter, effectively ...
Mission engineers at NASA's Jet Propulsion Laboratory in Southern California turned off the cosmic ray subsystem experiment aboard Voyager 1 on Feb. 25 and will shut off Voyager 2's low-energy charged particle instrument ...
Nova explosions occur in binary star systems in which a white dwarf—the dense remnant of a dead star—continually siphons stellar material from a nearby companion star. As the outer atmosphere of the companion gathers ...
Scientists from UNSW Sydney have located a potential new exoplanet—a planet that orbits a star outside of our solar system—using a technique known as "transit timing variation."
Radio astronomers see what the naked eye can't. As we study the sky with telescopes that record radio signals rather than light, we end up seeing a lot of circles.
By analyzing multiwavelength data from various space telescopes and astronomical surveys, Chinese astronomers have explored the long-term variability of a blazar known as PKS 0727-11. Results of the new study, published in ...
Water may have first formed 100–200 million years after the Big Bang, according to a modeling paper published in Nature Astronomy. The authors suggest that the formation of water may have occurred in the universe earlier ...
