This gigantic image of the Triangulum Galaxy — also known as Messier 33 — is a composite of about 54 different pointings with Hubble's Advanced Camera for Surveys. With a staggering size of 34,372 x ...

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 become ...

Astronomers have long thought the Milky Way was destined to merge with the nearby Andromeda galaxy. The aftermath of this predicted clash has been dubbed “Milkomeda,” and researchers predicted it ...

It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported Monday that the probability of the two spiral galaxies colliding is ...

An artist's concept depicts the Milky Way galaxy and its spiral shape. Our solar system is located in one of the spiral arms. - NASA/JPL-Caltech A collision between our Milky Way galaxy and its ...

A seemingly small, unassuming constellation is rising in the east after sunset: Triangulum. One of the smallest constellations (ranking 78th out of 88), this simple star pattern is nonetheless ...

More than a decade ago, scientists predicted our Milky Way galaxy and neighboring Andromeda would collide in four billion years, resulting in a “makeover” of our solar system. Now, that is unlikely — ...

NASA’s Hubble Space Telescope brings the vastness of space into perspective in this mosaic image of the Triangulum galaxy (M33), our neighbor in a collection of dozens of galaxies called the Local ...
