NASA image displaying the location
of young star clusters pinpointed from data collected by NASA's WISE spacecraft
Chikako Yasui and Naoto Kobayashi at the University of Tokyo, Japan, and colleagues observed two extremely
young star clusters in Cassiopeia 62,000 light years from the Milky Way's centre — over twice as far out as the sun — in a cloud of gas and dust named Digel Cloud 2.
During the first close approach just prior to four billion years in the future, the sky is ablaze with new star formation, which is evident in vast numbers of emission nebulae and
open young star clusters (Image: NASA / STScI)
The Antennae galaxies, named for their insectlike appearance (left, from ground - based telescope) are two merging spiral galaxies that have spawned over 1000
young star clusters visible as bright blue spots from t
Images taken by the Hubble Space Telescope of the Antennae galaxies — a pair of colliding galaxies named for their long tails of stars — have revealed over 1000 bright,
young star clusters triggered by the collision, astronomers said at a NASA press conference here today.
Glowing pink clouds of hydrogen gas harbor countless newborn stars, and the bluish - white hue of
young star clusters litter the landscape.
The
newfound young star clusters lie thousands of light - years below the plane of our Milky Way galaxy, a flat spiral disk seen in this artist's conception.
Recent surveys of
young star clusters indicate that relatively small objects — less than 13 times Jupiter's size, for instance — are common.
They then compared the two datasets with observations of the young stars in the Orion Nebula Cluster, perhaps the most well -
studied young star cluster in the Milky Way galaxy.
(2nd row right)-5 (3rd row left): 3.85 - 3.9 Billion Years - during the first close approach, the sky is ablaze with new star formation, which is evident in a plethora of emission nebulae and
open young star clusters.
Young star clusters and clouds of hydrogen that formed in our galaxy help trace the shapes of the Milky Way's arms, so astronomers are reasonably certain that it has a spiral structure (see right).
New observations of
a young star cluster in Orion reveal 18 free - floating red objects, including the three shown here, that resemble giant planets with masses between five and 15 times that of Jupiter.
These are mainly nebulae,
young star clusters and young, luminous, massive stars.
The IAU has not yet taken a position on free - floating objects of planetary mass outside star systems, other than to exclude those in
young star clusters.
The Rosette nebula is a circular nebula surrounding
a young star cluster.
The sharp «eye» of the Wide Field Camera 3 (WFC3) has captured hundreds of
young star clusters, ancient swarms of globular star clusters, and hundreds of thousands of individual stars, mostly blue supergiants and red supergiants.
