This long strand of stars streaks out of the Milky Way's disk in thesame manner as others seen in galaxies across the universe. Until now scientists had difficulties figuring just how faraway spiral arms are, and various measurements and techniques had discrepanciesranging by a factor of two. ...
The accuracy of the new measurement promises to help in the quest to detect the elusivegravitational wavespredicted by General Relativity. By monitoring an array of pulsars across theMilky Waygalaxy, scientists hope to measure the distortions of space-time caused by the passage of gravitational waves...
To put this in context, theMilky Way Galaxy, the galaxy we currently reside in, is about 100,000 Light Years across. The ARP 273 is, therefore, larger than our home galaxy. ARP 273 Angular Size The Angular Size is the size given as arc minutes, which can be roughly turned into light...
This is easy enough to understand: quasars are the most luminous objects that exist, outshining ordinary galax- ies by large factors. Because they are so lumi- nous, quasars appear relatively bright even when viewed across the vast stretches of the Universe. But over the past two years or ...
The Hubble Space Telescope image known as the "Einstein Cross" shows the light from a distant quasar after it has been bent by a nearby galaxy acting as a gravitational lens. (Image credit: NASA/ESA/STSci) RELATED STORIES: — Astronomers weighed our Milky Way, and it's lighter tha...
Analysis of the galaxy shows that it measures 300 light-years across and is estimated to have a mass of 40 million times that of the Sun. Tiny when compared to our own galaxy, which spans more than 100 000 light-years. It was also discovered that the galaxy is forming about one star ...
If you carry on and research that story…you’ll stumble across another little tale about another spec script titled:Troubleshooter.This also would eventually find its way before eager, action-seeking audiences. Though, they weren’t so eager when they came out ofSpeed 2: Cruise Control. ...

Andromeda Galaxy, great spiral galaxy in the constellation Andromeda, the nearest large galaxy. It is one of the few visible to the unaided eye, appearing as a milky blur. The Andromeda Galaxy is located about 2,480,000 light-years from Earth, and its di
