Astrophotographer Greg Meyer has captured a colorful view of the famous Trifid and Lagoon nebulas illuminated from within by radiation cast out by generations of energetic young stars.
An important clue to which perspective was right seemed to be hidden in the nebulae—fuzzy smears of light ("nebula" means "fuzzy") whose nature had been a source of debate for centuries. Some ...
Clearly, the Andromeda Nebula was a system of stars quite separate from the Milky Way, and in many ways comparable to it. From this simple observation, soon repeated for other starry nebulae, it ...
In this way, he obtained some of the first high-resolution pictures of prominent deep-sky objects such as the Pleiades (M45), Andromeda, the Triangulum Galaxy (M33), the Veil Nebula, and dozens more.
The embedded variable stars proved that the Andromeda nebula was much farther away than the stars that comprised the Milky Way. Andromeda was therefore a separate galaxy — similar to, yet ...
Take a deep breath: the universe is not just big it’s mind-bogglingly, practically scandalously huge. And it’s growing. A ...
THE DISTANCE OF THE ANDROMEDA NEBULA.- There have been several very discordant estimates of the distance of this object. A new one has now been made by Prof. Hubble, and is briefly described in ...
Andromeda, also called M31, is the closest giant neighboring galaxy at just 2.5 million light years away and home to at least a trillion stars. It wasn't always that way.
As early as 1912, astronomers realized that the Andromeda galaxy, then considered just a nebula, was heading toward us—toward the Milky Way. A century later, astronomers using NASA’s Hubble Space ...
For years, astronomers have predicted a dramatic fate for our galaxy: a head-on collision with Andromeda, our nearest large galactic neighbor. This merger—expected in about 5 billion years—has ...
There’s about a 50 percent chance that the Milky Way and Andromeda Galaxy will merge into a single giant galaxy, dubbed Milkomeda, in the next 10 billion years, a new analysis shows.
