Visualize the constellations and the stars contained within their boundaries
ResourceFunction["ConstellationChart"][const] generates a chart of the specified constellation const. |
"BoundaryLineStyle" | boundary line style | |
"GridStyle" | grid style | |
"HighlightedRegionStyle" | Opacity[0] | highlighted region style |
"LineArtStyle" | line art style | |
"MagnitudeLimit" | 5 | magnitude limit |
"MagnitudeScalingFunction" | (Max[0,0.02 -0.0023#1]&) | magnitude scaling function |
"MaskRegionStyle" | mask region style | |
"StarLabels" | Automatic | star labels |
"StarStyle" | star style |
Visualize the constellation Orion, its boundaries, line art, and the stars it contains:
In[1]:= | ![]() |
Out[1]= | ![]() |
Interpret the specified string as a constellation entity:
In[2]:= | ![]() |
Out[2]= | ![]() |
Supported constellations include Northern Hemisphere constellations, like Ursa Major:
In[3]:= | ![]() |
Out[3]= | ![]() |
Southern Hemisphere constellations like Crux are also supported:
In[4]:= | ![]() |
Out[4]= | ![]() |
The boundary line style can be changed:
In[5]:= | ![]() |
Out[5]= | ![]() |
The boundary line can also be turned off:
In[6]:= | ![]() |
Out[6]= | ![]() |
The style of the equatorial coordinate grid can be changed:
In[7]:= | ![]() |
Out[7]= | ![]() |
The equatorial coordinate grid can also be turned off:
In[8]:= | ![]() |
Out[8]= | ![]() |
The style of the highlighted region can be changed:
In[9]:= | ![]() |
Out[9]= | ![]() |
The highlighted region can also be turned off:
In[10]:= | ![]() |
Out[10]= | ![]() |
The style of line art can be changed:
In[11]:= | ![]() |
Out[11]= | ![]() |
Line art can also be turned off:
In[12]:= | ![]() |
Out[12]= | ![]() |
Fainter stars can be seen by changing the magnitude limit:
In[13]:= | ![]() |
Out[13]= | ![]() |
Constellations like Sagittarius have many faint stars due to being in the direction of the galactic center:
In[14]:= | ![]() |
Out[14]= | ![]() |
Constellations like Coma Berenices have relatively fewer stars due to being observed far from the galactic plane:
In[15]:= | ![]() |
Out[15]= | ![]() |
Provide a different scaling function for stars based on apparent magnitude:
In[16]:= | ![]() |
Out[16]= | ![]() |
The style of the outer mask region can be changed:
In[17]:= | ![]() |
Out[17]= | ![]() |
The outer mask region can also be removed:
In[18]:= | ![]() |
Out[18]= | ![]() |
Zooming into a specific area of a constellation region can be done using PlotRange, such as this view of the Pleiades star cluster in Taurus:
In[19]:= | ![]() |
Out[19]= | ![]() |
Label the eight brightest stars:
In[20]:= | ![]() |
Out[20]= | ![]() |
The style of the stars can be changed:
In[21]:= | ![]() |
Out[21]= | ![]() |
Stars can also be turned off:
In[22]:= | ![]() |
Out[22]= | ![]() |
ConstellationChart can accept any of the 88 official IAU-recognized constellations found in the "Constellation" entity type:
In[23]:= | ![]() |
Out[23]= | ![]() |
The current location of a given constellation in your local sky can be found using the resource function SkyChart:
In[24]:= | ![]() |
Out[24]= | ![]() |
Additional properties of constellations can be found using the entity framework:
In[25]:= | ![]() |
Out[25]= | ![]() |
The "Constellation" entity type provides the "ConstellationGraphic" property with similar results to ConstellationChart, but ConstellationChart provides options for customizing the results more easily:
In[26]:= | ![]() |
Out[26]= | ![]() |
The constellation Serpens is made up of two disjoint regions:
In[27]:= | ![]() |
Out[27]= | ![]() |
Create a darker themed result:
In[28]:= | ![]() |
Out[28]= | ![]() |
