Our Galaxy Is White

According to the conclusions of the latest study on the issue, it would appear that our galaxy is indeed the color of fresh snow. Researchers were finally able to establish the color of the Milky Way by looking at nearby galaxies of similar properties. Extrapolating from data they collected during this investigatio...

Sky Survey May Reveal the Composition of the Universe

For the past 12 years or so, the Sloan Digital Sky Surveys, part I, II and III, have been continuously analyzing the night sky, in an attempt to create digital 3D maps of how matter is distributed throughout. At this point, experts are trying to calculate how cosmic mass clumps up together based on these data. At th...

Sagittarius Loses Two Streams of Stars to the Milky Way

After analyzing data from the Sloan Digital Sky Survey (SDSS-III), investigators determined that two massive streams of stars were recently (in astronomical terms) removed from the Sagittarius dwarf galaxy, and incorporated into our own Milky Way. Astronomers have been proposing that such streams should become appar...

Early Universe May Have Spun on Its Axis

University of Michigan (U-M) physics professor Michael Longo and his research team have recently determined that the early Universe may have not displayed mirror symmetry. For a long time, experts have believed that the Cosmos was symmetric from any point of view. Astrophysicists compare this to a basketball &nda...

Not Many Galaxies Have Neighbors

Astronomers at the Stanford University say that only 4 percent of all the galaxies in the Universe have neighbors, like the Milky Way does. Our galaxy has at least two dwarf galaxies as companions, but it may also feature other, yet-undetected neighbors. Throughout the Universe, this is a fairly rare situation, i...

Distant Universe Mapped in 3D

A team of astronomers announces the completion of the most impressive, complete and thorough three-dimensional map of the distant Cosmos ever created. The new dataset was created using an unusual technique, and does not feature galaxies.Rather than looking at starlight coming from these large-scale structures, the sc...

Why Some Black Holes Are Hyperactive

In their studies of the universe, astronomers have found a large number of black holes of various shapes, sizes and types, but they have always been fascinated about why some of these dark behemoths are so much more active than others. A new study sheds some light on the possible answers. One of the things setting a...

China Builds World's Biggest Fixed Spectrometer Telescope

Chinese researchers' long dream of building a facility better but still relying on the technology used on a national scale for astronomical search purposes has finally come true. Housed in a building that looks like a nuclear missile silo and a messed up PI symbol lies their latest achievement, the Large sky Are...
