The Milky Way is a breathtaking example of the wonders of cosmic creation within the vast and mysterious realm of the cosmos. The Milky Way’s music has been discovered by scientists and artists alike as they have investigated additional sensory qualities of the galaxy beyond the visual spectacle. This article will take readers on a ...
In the grand tapestry of the cosmos, there exists a celestial wonder that has captured the imagination of humanity for eons — the Milky Way. Spanning vast stretches of the night sky, this cosmic masterpiece is more than just a distant spiral of stars. The Milky Way is humanity’s heavenly home, a beacon of mystery ...
Our Milky Way galaxy is an awe-inspiring feature of the night sky, viewable with the naked eye as a hazy band of stars stretching from horizon to horizon. For the first time, the IceCube Neutrino Observatory in Antarctica has produced an image of the Milky Way using neutrinos — tiny, ghost-like astronomical messengers. In research ...
Two major astronomy research programs, called EMU and PEGASUS, have joined forces to resolve one of the mysteries of our Milky Way: Where are all the supernova remnants? A supernova remnant is an expanding cloud of gas and dust marking the last phase in the life of a star, after it has exploded as a ...
Astronomers say they have solved an outstanding problem that challenged our understanding of how the universe evolved — the spatial distribution of faint satellite galaxies orbiting the Milky Way. These satellite galaxies exhibit a bizarre alignment — they seem to lie on an enormous thin rotating plane — called the “plane of satellites.” This seemingly ...
The first map of the “galactic underworld” — a chart of the corpses of once massive suns that have since collapsed into black holes and neutron stars — has revealed a graveyard that stretches three times the height of the Milky Way and that almost a third of the objects have been flung out from ...
An animated dive into the dusty Milky Way reveals the outlines of our galaxy taking shape as we look out further and further from Earth. Based on new data from an interactive tool that exploits data from the European Space Agency’s Gaia mission and other space science data sets, astronomers have created an animation to ...
where the Milky Way’s cosmic rays come from is a step closer to being revealed. Astronomers have succeeded for the first time in quantifying the proton and electron components of cosmic rays in a supernova remnant. At least 70 percent of the very-high-energy gamma rays emitted from cosmic rays are due to relativistic protons, according ...
University of Arizona researchers have observed, in unprecedented detail and spatial resolution, organic molecules in planetary nebulae, or the aftermath of dying stars. Their work sheds new light on how stars form and die. Using the Atacama Large Millimeter Array, or ALMA, UArizona Regents Professor Lucy Ziurys and her collaborators observed radio emissions from hydrogen cyanide, formyl ...
The Milky Way is a spiral galaxy, which means that it is composed, among other components, of a disc of stars, gas, and dust in which the spiral arms are contained. At first, it was thought that the disc was completely flat, but for some decades now it has been known that the outermost part ...
