It is sent to fetch water, but it rests lazily on the journey, and after finally obtaining the water in a cup, takes back a water snake as well, as an excuse. According to the myth, Apollo saw through the fraud, and angrily cast the crow, cup, and snake, into the sky. The origin of this story is likely to be the juxtaposition of this constellation with those of Crater , and Corvus , in the area of the sky known as the Sea.
Its position in the sky below the ecliptic , together with the constellation Cancer which lies near its head may be the origin of parts of the myth. Space Wiki Explore. The Known Universe. Astronauts Yuri Gagarin Neil Armstrong. UltraHyperBear New guy Wingman1. Apollo also turned the water snake and the cup into constellations. In the sky, the water snake Hydra eternally prevents the crow Corvus from drinking out of the cup Crater. Alpha Hydrae has an apparent magnitude of 2. It is the brightest star in the constellation. It has three solar masses, 50 times the solar radius, and is believed to be around million years old.
Gamma Hydrae is the second brightest star in Hydra. It has an apparent magnitude of 2. It has the stellar classification of G8 III, which makes the star a yellow giant. Gamma Hydrae has three solar masses and 13 times the solar radius. It is times more luminous than the Sun, but significantly younger. Its age is estimated to be around million years. Zeta Hydrae is the third brightest star in Hydra constellation, with an apparent magnitude of 3.
The star is believed to be around million years old. Zeta Hydrae is an evolved giant in the luminosity class between a giant and bright giant. Beta Hydrae is a binary star light years distant from the solar system. It has a combined apparent magnitude of 4. The primary component in the system is a giant Bp star classified as an alpha-2 Canum Venaticorum type variable. It is a chemically peculiar class B star with a strong magnetic field. The star is believed to have a low-mass companion, an M class dwarf.
The system is believed to have a substellar companion orbiting it with a period of 9. Sigma Hydrae has the stellar classification K1III — an orange giant — and an apparent magnitude of 4. It is approximately light years distant from the Sun. R Hydrae is a Myra-type variable star, a red pulsating variable star in the late stage of evolution, with the stellar classification of M7IIIe. It is a red giant with an apparent magnitude that slowly changes from 3. The star is approximately light years distant.
Bow shocks are formed where the stellar wind from a star are pushed into a bow shape illustration, right panel as the star plunges through the gas and dust between stars. Our own Sun has a bow shock, but prior to this image one had never been observed around this particular class of red giant star. R Hya moves through space at approximately 50 kilometers per second. As it does so, it discharges dust and gas into space. Because the star is relatively cool, that ejecta quickly assumes a solid state and collides with the interstellar medium. The resulting dusty nebula is invisible to the naked eye but can be detected using an infrared telescope.
This bow shock is 16, AU from the star to the apex and 6, AU thick. The mass of the bow shock is about times the mass of the Earth. The false-color Spitzer image shows infrared emissions at 70 microns. Brighter colors represent greater intensities of infrared light at that wavelength. The location of the star itself is drawn onto the picture in the black unobserved region in the center. Ueta Univ. V Hydrae is a carbon star with the stellar classification C9I. The star is classified as a semi-regular variable. Its apparent magnitude ranges from 7. V Hydrae is approximately 1, light years distant. U Hydrae is another carbon star in Hydra constellation. It is one of the few carbon stars that can be seen without binoculars.
It is a bright giant with an apparent magnitude of 4. The star is approximately light years away. U Hydrae is a variable star, showing variations in brightness ranging from 4. Epsilon Hydrae is a multiple star system in Hydra. It is approximately light years distant from Earth. The system consists of at least four stars. The main component, the binary star Epsilon Hydrae AB, has an apparent magnitude of 3. The stars have an orbital period of 15 years and are separated by 0.Also hydra (constellation) of the longest at hydra (constellation) degrees, hydra (constellation) southern end hydra (constellation) Libra and Centaurus and its northern end hydra (constellation) Cancer.
