Latest Andromeda Stories
In a study that pushes the limits of observations currently possible from Earth, a team of NASA and European scientists recorded the "fingerprints" of mystery molecules in two distant galaxies, Andromeda and the Triangulum. Astronomers can count on one hand the number of galaxies examined so far for such fingerprints, which are thought to belong to large organic molecules, says the team's leader, Martin Cordiner of the Goddard Center for Astrobiology at NASA's Goddard Space Flight...
Milky Way Bigger Than Once ThoughtThe Milky Way packs a big punch. In fact, scientists discovered that it is larger than Andromeda - not the little sister it was once thought to be.Scientists mapped the Milky Way in a more detailed, three-dimensional way and found that it's bulkier and spinning faster than astronomers once thought.The Milky Way is denser, with 50 percent more mass, and 15 percent larger in breadth. The research was presented Monday at the American Astronomical Society's...

Cetus Constellation -- Cetus (the Whale or Sea Monster) is a constellation of the southern sky, in the region known as the Water, near other watery constellations like Aquarius, Pisces, and Eridanus. Notable features This constellation's most notable star is Mira, ο Ceti, the first variable star to be discovered. Over a period of 331.65 days it varies from magnitude 2.0, one of the brightest in the sky and easily visible to the unaided eye, to 10.1 and back again. Its discovery in...
Andromeda Constellation -- Andromeda is a constellation representing the princess Andromeda, in the northern sky near Pegasus. The constellation takes the general shape of a long, dim, straggly letter "A". It is most notable for containing the Andromeda Galaxy. Notable features The brightest star in Andromeda, α Andromedae, called Alpheratz or Sirrah, makes up with α, β, and λ Pegasi an asterism called the Great Square of Pegasus. This star was once considered part of...
Andromeda Galaxy -- The Andromeda Galaxy, also known as M31, or the object 31 on the catalog of Messier, is the other giant spiral galaxy in the Local Group, together with our galaxy, the Milky Way. It is at a distance of approximately 2.36 million light years or 725 kpc, in the direction of the constellation Andromeda, and it will probably merge in the future with our galaxy, to form a giant elliptical. With a mass of about 1.5 times more than the Milky Way, it is the dominant galaxy...
