The first glimpse of starlight from a galaxy hosting one of the most distant quasars known has revealed an astronomical wonder. Quasars – extremely bright galactic nuclei – owe their brightness to the intense heat that results when gas swirls […]
For the first time, scientists have measured a long-sought global electric field in Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but was never discovered until now. his animation shows how the ambipolar […]
The opposing fountains of plasma and particles spanning 23 million light-years are the longest pair of black hole jets ever seen. That’s far enough away to affect the evolution of the universe on a cosmic scale, astronomers report Sept. 18. […]
A red dwarf star known as Barnard’s Star, located just six light-years from our solar system, has at least one — and possibly a handful — of small rocky planets orbiting it, a new study suggests. . Barnard’s Star, which […]
Satellites interfere with radio astronomy – Scientific news, October 5, 1974 In the past, satellites and probes launched by NASA and others successfully avoided conflict with the radio frequency bands reserved for radio astronomy. But now there is trouble. The […]
Dozens of runaway stars were caught escaping from a dense star cluster in a satellite galaxy of the Milky Way. The cluster of fast-moving stars may mean that such runaways had a greater influence on cosmic evolution than previously thought, […]
