Where is hydra located in the sky

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. Epsilon Hydrae A, the primary component, is 67 times more luminous than the Sun.

Epsilon Hydrae C is a spectroscopic binary star of the spectral type F5 with an apparent magnitude of 7. It is separated from the main pair by 3 seconds of arc. It has a period of 9. Epsilon Hydrae D is separated from the main pair by 19 seconds of arc and is believed to be gravitationally bound to the Epsilon Hydrae system because it shares a common proper motion with the other stars. The star has an estimated orbital period of 10, years. Nu Hydrae is an orange giant star located near the border with Crater constellation.

It has an apparent magnitude of 3. The star has a radius 21 times solar and is times more luminous than the Sun. It is a known X-ray source. Pi Hydrae has the stellar classification of K1 III-IV, which means that it is an orange star halfway between the subgiant and giant stage of evolution. It has a visual magnitude of 3. The star can be seen without binoculars. It has 2. Delta Hydrae is a binary star in Hydra, about 17 times more luminous than the Sun.

It has the stellar classification of A1V, which means that it is a white dwarf. Messier 48 is an open star cluster in Hydra, believed to be about million years old. It has an apparent magnitude of 5. The cluster was discovered by Charles Messier in It can be seen without binoculars under good conditions. Messier 68 is a globular cluster in Hydra, also discovered by Charles Messier, in It has an apparent magnitude of 9. Hydra Cluster is a galaxy cluster in Hydra.

These galaxies are all about , light years in diameter. The cluster is notable for having a high proportion of dark matter.

The Hydra Cluster is It is part of the larger Hydra-Centaurus Supercluster, which is approximately million light years distant from the Sun and includes galaxies in the constellations Centaurus , Hydra and Norma. Messier 83 , or the Southern Pinwheel Galaxy, is a barred spiral galaxy in Hydra.

It has a visual magnitude of 7. The Southern Pinwheel Galaxy is one of the nearest and brightest barred spirals discovered, and can be observed with binoculars. NGC is a planetary nebula in Hydra. M68 is a globular star cluster containing more than 2, stars.

M83 is a magnificent spiral galaxy also known as the Southern Pinwheel. This constellation also contains a number of dim deep-sky objects that can only be seen with large telescopes. NGC is a pair of galaxies that appear to overlap. All though they seem to be colliding, one galaxy is in front of the other from our perspective and they are actually separated by a vast distance.

As darkness falls on spring evenings, we can trace out the entire figure of this long star pattern, starting with its head, located halfway up in the southwest sky, surrounded by stars generally associated with late winter and early spring in the constellations Gemini, Cancer and Leo.

If we follow this winding group back toward the east all the way to its end, we'll eventually come to the tip of its tail hovering low in the southeast, not far from the star patterns we would associate with early summer Libra, Scorpius. Tracing the long, slinky body of Hydra makes it clear why the ancient stargazers referred to these stars as a snake.

Some authors refer to Hydra as a sea serpent, and not a few star guides have linked the constellation with the nine-headed swamp monster that Hercules killed by cauterizing each neck as he decapitated it.

That beast, too, was known as Hydra. Some point out that when the constellation Hercules triumphantly appears high overhead on warm summer evenings, Hydra has all but slithered out of sight below the southwest horizon, with only the tip of its tail in view.

But the true origin of our celestial snake may be in Mesopotamia. Ed Krupp, director of the Griffith Observatory in Los Angeles, has pointed out that an engraved stone from the Seleucid period B.

Leo, the lion, which lies above Hydra, marches upon the sea monster's back in the ancient drawing, just as happens in the sky.

Older Babylonian star lists also include a serpent in these stars. Hydra's head stands out well because it is located in a region of the sky relatively sparse in bright stars. This part of the constellation actually looks like the head of the celestial denizen it is supposed to portray. Seen through a pair of wide-field binoculars, Hydra's head almost looks like a loose open-star cluster, thanks chiefly to several fainter stars.

But in reality, this is just an illusion of perspective; these stars are all unrelated to each other. To the north of Hydra's head is the famous Beehive star cluster in Cancer, M44, which to the eye appears as a fuzzy patch of light — but with good binoculars, it immediately appears as a splattering of dozens of tiny stars. If you are blessed with a very dark sky, you can see the outlying members of the cluster spanning an area nearly three times the diameter of a full moon.

Midway between the Beehive and Hydra's head is the dense, open cluster M67, nicknamed the King Cobra cluster.
