What telescope is used to see the brightest stars in the constellation?

NASA’s Hubble Space Telescope recently captured a detailed view of the brightest stars in the constellation.

What is the shape of Hercules?

From the southern side of the quadrangle the upper half of the body broadens to the shoulders. The shape is formed with Hercules leaning slightly forward. The brightest star Kornephoros is almost in a direct line with the keystone asterism. While Sarin the other shoulder is at a 45 degree angle and nearer the quadrangle. The geometrically shaped Hercules head is marked by Ras Algethi which is equidistant from the shoulders similar to the distance of the shoulders to the body.

What constellations are in the summer triangle?

The summer triangle connects three constellations. The tail of Cygnus the swan (Deneb – 19 th brightest star), the handle in the Lyra constellation (Vega – 5 th brightest star), and the tail of the eagle in the Aquila constellation (Altair – 12 th brightest star). All are north of Sagittarius.

What is the name of the constellation with a diamond shaped instrument?

Lyra is a small constellation with a diamond shaped instrument with a handle. Vega is the primary star that represents the handle and the diamond is dissected by the line towards Altair in the summer triangle. The full length of Lyra reaches less than half way to the head of Cygnus.

Where is Hercules in the constellation?

Hercules is visible overhead north of Ophiuchus, alongside Lyra and near to the head of Draco. The constellation has a lack of bright stars and is a complex shape which makes it difficult to identify. However the shape is of a body builder and is therefore rewarding once identified. The head of Hercules is pointed southward and the legs stand over the head of Draco in the north sky. The brightest star in the Constellation is Kornephoros which is one of Hercules shoulders.

What is the arm of Vega?

The arm reaching towards Vega is perpendicular to the body and is a string of stars forming a straight line. The arm extending from Kornephoros is raised and forms a slight curve of faint stars that reach a height similar to Hercules head.

What constellation is Virgo?

Virgo is the constellation of the Virgin and it is associated with fertility. Virgo is between Leo to the west and Libra to the east.

Why is it important to identify the night sky immediately east of the summer triangle?

Because Hercules lacks bright stars it is important to first orient yourself to the correct area of sky. The easiest way is to identify the night sky immediately east of the summer triangle. Immediately east of Vega there is a quadrangle that forms the lower half of Hercules body. The square like shape is known as the keystone asterism.

What nebula gives birth to stars?

Trifid Nebula. The steam above the spout includes two nebulae that are giving birth to new star clusters: M8 (the Lagoon Nebula) and M20 (the Trifid Nebula). The Lagoon has given birth to scores of stars, with more taking shape even now. Through binoculars or a small telescope, it looks like a hazy oval of light.

What does M20 look like?

Through binoculars or a small telescope, it looks like a hazy oval of light. Photographs show a reddish-pink glow, which is the color of hydrogen atoms being zapped by the radiation of young stars. Lanes of dark dust across the face of M20 give it a three-part appearance.
