Analyzing deep-infrared images obtained by the Spitzer Space Telescope and Gemini North telescope, astronomers discovered that one of the stars in the cluster, HD 23514, which has a mass and luminosity a bit greater than that of the Sun, is surrounded by an extraordinary number of hot dust particles. This could be evidence for planet formation ...
Star map with the Pleiades (upper right) and the Hyades (centre, V-shaped head of the constellation Taurus with its main star Aldebaran, γ Tauri und ε Tauri (Ain)) at both sides of the ecliptic line (dashed red). The Golden Gate of the Ecliptic is an asterism in the constellation Taurus that has been known for several thousand years.
Pleiades seen with the naked eye (upper-left corner). [1]The high visibility of the star cluster Pleiades in the night sky and its position along the ecliptic (which approximates to the Solar System's common planetary plane) has given it importance in many cultures, ancient and modern.
When our sun dies about 5 billion years from now it might look something like this glowing celestial display which was captured from 4,600 light-years away. Hubble image of a star exploding may ...
Annotated night sky image showing Auriga and the Pleiades—Capella is the brightest star, towards top left With an average apparent magnitude of +0.08, Capella is the brightest object in the constellation Auriga , the sixth-brightest star in the night sky, the third-brightest in the northern celestial hemisphere (after Arcturus and Vega ), and ...
However, many more stars are visible with even a modest telescope. [21] Astronomers estimate that the cluster has approximately 500–1,000 stars, all of which are around 100 million years old. However, they vary considerably in type. The Pleiades themselves are represented by large, bright stars; also many small brown dwarfs and white dwarfs exist
The pillars shown in the image are 5 light-years tall, which means that the distance from one end to the other is roughly 300,000 times as far away as Earth is from the sun.
The term Pleiades Phenomenon was coined by astronomer Paul Kalas who discovered five nebulosities not related to star forming regions using a coronagraph. [2] The nebulosities were found to have "linear, filamentary, striated morphological structure" located between 1000 and 100,000 astronomical units from each star.
