Lee Rannals for redOrbit.com According to recent studies with the National Science Foundation's Green Bank Telescope (GBT), a couple celestial neighbor galaxies may have had a close encounter with each other billions of years ago. Astronomers confirmed a disputed 2004 discovery of hydrogen gas streaming between the giant Andromeda Galaxy and the Triangulum Galaxy with their new study. "The properties of this gas indicate that these two galaxies may have passed close together in the...

Milky Way Destined For Head-On Collision

[ Watch the Video ] NASA astronomers announced on May 31 that they can now predict with certainty the next major cosmic event to affect our galaxy, sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy. The Milky Way is destined to get a major makeover during the encounter, which is predicted to happen four billion years from now. It is likely the sun will be flung into a new region of our galaxy, but our Earth and solar system are in...

Rare Ultra-Blue Stars Among Hubble Andromeda Finds
2012-01-12 05:49:30

[ Watch the Video ] Images taken by the Hubble Space Telescope have revealed both a cluster of rare ultra-blue stars and a "double nucleus" of old, reddish stars orbiting a 100-million-solar-mass black hole at the nearby Andromeda spiral galaxy, NASA officials announced on Wednesday. The discoveries, detailed by the U.S. space agency in separate press releases, were also presented Wednesday at the American Astronomical Society (AAS) meeting in Austin, Texas. A paper detailing the Hubble...

The Andromeda Galaxy is revealed in unprecedented detail in four archive observations from the NASA/ESA Hubble Space Telescope. They show stars and structure in the galaxy's disc, the halo of stars that surrounds it, and a stream of stars left by a companion galaxy as it was torn apart and pulled in by the galaxy's gravitational forces. These four observations made by Hubble's Advanced Camera for Surveys give a close up view of the Andromeda Galaxy, also known as Messier 31 (M 31)....

A team of astronomers from the UK, the US and Europe have identified a thick stellar disc in the nearby Andromeda galaxy for the first time. The discovery and properties of the thick disc will constrain the dominant physical processes involved in the formation and evolution of large spiral galaxies like our own Milky Way. By analyzing precise measurements of the velocities of individual bright stars within the Andromeda galaxy using the Keck telescope in Hawaii, the team have managed to...

The Andromeda Galaxy was formed as the result of a massive collision involving two separate galaxies that occurred billions of years ago, an international team of researchers has discovered. The astronomers, led by Francois Hammer of the Paris Observatory, conducted complex computer simulations of the galaxy's structural formation, both in France and at the National Astronomical Observatory of China (NAOC). They then analyzed the results and prepared a study, which has been published in the...

Observations from NASA's Spitzer Space Telescope reveal a distant planet with a warm spot in the wrong place. The gas-giant planet, named upsilon Andromedae b, orbits tightly around its star, with one face perpetually boiling under the star's heat. It belongs to a class of planets termed hot Jupiters, so called for their scorching temperatures and large, gaseous constitutions. One might think the hottest part of these planets would be directly under the sun-facing side, but previous...

For over 10 years, NASA's Chandra X-ray Observatory has repeatedly observed the Andromeda Galaxy for a combined total of nearly one million seconds. This unique data set has given astronomers an unprecedented view of the nearest supermassive black hole outside our own Galaxy. Astronomers think that most galaxies - including the Milky Way - contain giant black holes at their cores that are millions of times more massive than the Sun. At a distance of just under 3 million light years from...

Astronomers are reporting today the discovery of a planetary system way out of tilt, where the orbits of two planets are at a steep angle to each other. This surprising finding will impact theories of how multi-planet systems evolve, and it shows that some violent events can happen to disrupt planets' orbits after a planetary system forms, say researchers. "The findings mean that future studies of exoplanetary systems will be more complicated. Astronomers can no longer assume all planets...

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...
