Thus, dark matter's gravitational impact is extremely spread out and, it turns out, can only be observed when we look at the large-scale distribution of visible matter in the universe: things like galactic superclusters and the corresponding super-voids. It's theorized that after the Big Bang...
Wenmang is not a superman, a superman is still a human being, and there are people's bad habits. Superman is only an elite of people, while Wenmang is not a known person (nor a superman), but outside and above people. In this doomsday, it can't be a traditional person or a ...
It is only these AGNs that are defined as radio galaxies. What fuels "radio loud" active galactic nuclei? A multi-wavelength image of radio galaxy Centaurus A. (Image credit: X-ray: NASA/CXC/SAO; optical: Rolf Olsen; infrared: NASA/JPL-Caltech; radio: NRAO/AUI/NSF/Univ.Hertfordshire/...
The Hyades cluster is one of the nearest galactic clusters, and it is roughly 130 light-years away in the center. This moving group of stars is drifting slowly away towards Orion, and in another 50 million years it will require a telescope to view! Tuesday, November 20 –Today celebrates ...
Launch Visibility Map for the Starliner Crew Flight Test. Credit: ULA A post-launch news conference is scheduled for midnight, docking will be just over 24 hours later at 12:48 am ET Wednesday, followed by hatch opening, an in-orbit welcome ceremony, and a post-arrival press conference at...
Stars at the Galactic Center. Credit: Astronomy Image Gallery “The observations at the center of the Milky Way have taught us that one, it’s really normal to have a black hole at the center of the galaxy. I mean, our galaxy is completely ordinary, garden-variety, nothing-special-about...
“Speed of light is as fast as you’re gonna go.” Alien Engineering Even if aliens did crack the code on the galactic speed limit, they could still face other problems, says Scott McCormack, Ph.D., an assistant professor of materials science and engineering at University of California, ...
A zoomable version of the photo allows us to view our galactic neighbor up close and reminds us that we are but tiny specks in the vastness of the universe. This photo also has an interesting connection to 16.00x: Prof. Hoffman was one of the astronauts on STS-61, the first Space ...
Stellarium is a free GPL software which renders realistic skies in real time with OpenGL. It is available for Linux/Unix, Windows and MacOSX. With Stellarium, you really see what you can see with your eyes, binoculars or a small telescope. - HollisJoe/st
