To answer this question, the researchers ran “the most complete and accurate to date” simulation of the formation of a Milky Way-like galaxy — a simulation that included not only the stars, but the gases between them. To run that simulation, they used ATERUI II, NAOJ’s in-house super...
But space telescopes and unmanned probes also study the further reaches of what's called interstellar space (the space between stars), measured in vastly greater distances called light years (the distance light travels in one year, which is almost 10 trillion kilometers). The Milky Way galaxy,...
The Milky Way galaxy is estimated to be 1 trillion to 2 trillion times more massive than the sun, according to CfA researchers. Most of that mass (about five-sixths) is dark matter, while the remaining mass consists of normal matter — gas, dust and stars. Even still, when astronomers ...
The problem originated as a quip by Enrico Fermi to colleagues in Los Alamos over lunch one day in 1950. Whether one assumes the existence of only one other civilization or of many alien civilizations in our Milky Way galaxy, and whether one assumes colonization involving interstellar travel at...

the Galaxy in November 2010. The discovered structures are elongated and are symmetrically located in the Galactic plane perpendicular to its center, extending 50,000 light-years, or roughly half of the diameter of the Milky Way disk. These structures became known as Fermi bubbles. Later, the ...
MAXI J1348−630 is a low-mass X-ray binary located within the Milky Way galaxy. Although its physical characteristics are not yet fully understood, multiple outbursts have been observed in this source [37]. Different types of QPOs have been detected during these outbursts. Spectral analysis ...
Milky Way could invalidate the hypothesis of exotic matter and favor a gravitomagnetic solution to explain dark matter 来自 Springer 喜欢 0 阅读量: 1 作者: SL Corre 摘要: We demonstrate a very general mathematical and physical expression of the rotation speed at the end of the galaxy (far ...
“Transferring mass onto a neutron star is an effective mechanism to create rapidly spinning (millisecond) pulsars,” Vigna-Gomez said. “Avoiding this mass transfer episode as we suggest hints that there is a radio-quiet population of such systems in theMilky Way.” ...
