Scientific name: Gagea lutea. The Yellow star-of-Bethlehem is a woodland plant that lives up to its name – it displays starry, gold flowers in an umbrella-like cluster in early spring.
Are star flowers perennials?
The Spring Starflower is a bulbous perennial that grows up to 10″ tall. This South American ground cover tolerates drought but should be kept moist during the growing season. In early spring, its bulb produces grass-like foliage and multiple flowering 6″ stems with single white to violet-blue star flowers.

How can you tell how old a star cluster is?
By determining the mass of the main-sequence turnoff stars, we get the age of the cluster. The cluster age equals the main-sequence lifetime of the turnoff stars. This is one of the ways we have studied the age of the Universe and the formation history of the Galaxy.
How long do star clusters last?
“The average lifespan of such a star cluster thus increases to about a few hundred million years. Star clusters whose mass contains 25 percent of the original gas mass can even live up to a billion years.” Observations of the oldest open star clusters in the Milky Way substantiate this result.
What is the difference between a star cluster and a galaxy?
Star clusters and galaxies both contain stars bound together by gravity, but while the members of a star cluster are thought to form simultaneously from a collapsing ball of gas, galaxies have richer histories.
What are the three types of star clusters?
There are three main types of star clusters: globular clusters, open clusters, and stellar associations, each of which has different properties that provide different information to astronomers.
What are the 2 types of star clusters called?
The two basic categories of stellar clusters are open clusters, also known as galactic clusters, and globular clusters.
What does a galaxy cluster look like?
The extra energy in the light means it disappears from the CMB, so a galaxy cluster looks like a “hole”. This property of galaxy clusters is called the Sunyaev-Zel’dovich effect, and it helps astronomers find galaxy clusters even if they’re too far or faint to be seen easily by the light they emit.
What is the nearest galaxy cluster to Earth?

What does an SBc galaxy look like?
characteristics. In SBc galaxies, both the arms and the bar are highly resolved into star clouds and stellar associations. The arms are open in form and can start either at the ends of the bar or tangent to a ring.
What does a SBb galaxy look like?
SBb systems have a smooth bar as well as relatively smooth and continuous arms. In some galaxies of this type, the arms start at or near the ends of the bar, with conspicuous dust lanes along the inside of the bar that can be traced…
What does a Seyfert galaxy look like?
Seen in visible light, most Seyfert galaxies look like normal spiral galaxies, but when studied under other wavelengths, it becomes clear that the luminosity of their cores is of comparable intensity to the luminosity of whole galaxies the size of the Milky Way.
