Halo (Halo, #1) by Alexandra Adornetto

An angel is sent to Earth on a mission.
But falling in love is not part of the plan.

Three angels – Gabriel, the warrior; Ivy, the healer; and Bethany, the youngest and most human – are sent by Heaven to bring good to a world falling under the influence of darkness. They work hard to conceal their luminous glow, superhuman powers, and, most dangerous of all, their wings, all the while avoiding all human attachments.

Then Bethany meets Xavier Woods, and neither of them is able to resist the attraction between them. Gabriel and Ivy do everything in their power to intervene, but the bond between Xavier and Bethany seems too strong.

The angel’s mission is urgent, and dark forces are threatening. Will love ruin Bethany or save her?

Dual Interpretations: Milky Way's Outer Fringe of Stars Sparks Disagreement

We inhabit a giant spiral-shaped galaxy that glows with hundreds of billions of stars, a colossus so massive that at least two dozen lesser galaxies revolve around it. But how did this enormous entity arise? Clues come from the Milky Way's oldest and wisest stars—those in the stellar halo, the galactic component that envelops the bright disk housing the sun. Halo stars stand out because they formed before supernova explosions had scattered a large amount of heavy elements into the galaxy, so halo stars possess little iron. The brightest halo members are iron-poor globular star clusters, spectacular objects that can pack hundreds of thousands of old stars into a sphere just a few dozen light-years across. Now the Hubble Space Telescope has found that an individual halo star is even older than these ancient star cities and is thus an ideal time capsule passed down from the Milky Way's birth. Despite its importance, the stellar halo constitutes just a thousandth of the Milky Way's total mass.

Halo is defined as the region in galaxy in which stars are scattered thinly. They contain globular clusters of stars. This region is surrounded by.

Globular Clusters:. Originally it was thought that all globular clusters were part of the halo.

Galactic halo , in astronomy , nearly spherical volume of thinly scattered stars, globular clusters of stars, and tenuous gas observed surrounding spiral galaxies, including the Milky Way —the galaxy in which the Earth is located.

The Milky Way is the galaxy [nb 1] that contains the Solar System , with the name describing the galaxy's appearance from Earth : a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. Galileo Galilei first resolved the band of light into individual stars with his telescope in Until the early s, most astronomers thought that the Milky Way contained all the stars in the Universe. The Milky Way is a barred spiral galaxy with a diameter between , and , light-years ly. The stars in the innermost 10, light-years form a bulge and one or more bars that radiate from the bulge. Stars and gases at a wide range of distances from the Galactic Center orbit at approximately kilometers per second. This conjectural mass has been termed " dark matter ".

January 31, Many stars in the halo that surrounds the Milky Way travel in groups. This is the outcome of a recent analysis of data for millions of stars from the Gaia space mission. The Milky Way, our own Galaxy, has likely formed in part from the merging of many smaller systems. How exactly that happened, is still a puzzle. To learn more about the history of formation of the Milky Way, astronomers from the University of Groningen in the Netherlands and UC Riverside in the US, have inspected the motions of stars in the so-called Galactic halo. Stars in the halo are more pristine and spend most of their time outside of the disk-like structure that gives the Milky Way its name.
