Sky Chart of Sagittarius Constellation Here we provide a simplified sky chart of the Sagittarius constellation. Alternatively it is possible to locate Sagittarius in the night sky using our Online Interactive Planetarium.
In case of very large constellations like Sagittarius actually is these times can have little relevance. The table below lists the top 20 brightest stars in the Sagittarius constellation. Then determine whether your intended observing time occurs before or after the constellation's meridian transit time during that night. Look along your latitude entry in the table, locate the appropriate column showing the number of hours difference, and look down the sub-column BT if your observing time is before meridian transit or AT if your observing time is after meridian transit.
The resulting entry gives the direction and altitude of Sagittarius at the time and latitude you are requesting. BT - B efore Meridian T ransit. AT - A fter Meridian T ransit. R - the constellation is Rising. S - the constellation is Setting. Alt - Altitude angle above the horizon rounded to the nearest whole degree.
The altitude shown applies for both BT and AT. The table entry for August 12th also has a black background, so we know the constellation transits in darkness and that it will easily be visible at this time. Looking at the Direction and Altitude table above, we can now see where Sagittarius will be at other times during the night.
The results can be listed as follows:. Time relative to Meridian Transit time. Local Time. Sky Colour. Meridian Transit column headed 0 hours. We can therefore decide our observing time based on the times and positions we have determined. Alternatively, we can start with an intended observing time and find the constellation's position based on the time offset from its meridian transit.
Say for example we wish to observe at around DST Finally, refer to the animation appropriate to your latitude to see how the constellation will appear in the sky whether tilted left or right from vertical at the time you have chosen.
Occupying the Southwestern region of Sagittarius is an asterism star pattern commonly called ' The Teapot ', which includes the constellation's brightest stars. The word 'Kaus' is Arabic for 'bow'; the remaining parts of the names are Latin for 'northern', 'middle' and 'southern', respectively. This is evident by examining the meridian transit times in the Meridian Transit table the planets, on the other hand, move slowly against the 'fixed' star background, so this rule does not apply to them in the strictest sense.
Consequently, on August 13th one day after the 12th Sagittarius will appear in the same directions and altitudes as we determined above, but four minutes earlier than the times on August 12th. Precise rising and setting times of Sagittarius , together with sky colorations, are given in the table below.
Rising and Setting Times of Sagittarius. The following table lists the rising and setting times of Sagittarius for a variety of latitudes times are listed for the 1st , 11th and 21st day of each month - to obtain the times at intermediate dates, apply the ' four minutes per day ' rule discussed above.
Rising and setting times of the constellation Sagittarius , listed in hour clock format hours:mins on the 1st, 11th and 21st day of each month. The sky colour codings are the same as those described under the Meridian Transit table above. All the above times were obtained from the commercial software Redshift 5.

Site hosted by. Kaus Australis mag 1. The subgiant has an apparent magnitude of 3. The companion star has an apparent magnitude of 5. Upsilon Sagittarii is a spectroscopic binary star. It is one of only four star systems known to be hydrogen-deficient, which makes it difficult to classify U Sgr.
Most likely, the primary component is an A type supergiant. It is classified as an irregular variable star, with an apparent magnitude varying from 4. The companion star is more massive than the primary, but so faint that optical telescopes cannot detect it. The Upsilon Sagittarii system is about 1, light years distant and has an orbital period of Ross is a red dwarf only 9.
It is one of the closest stars to the Sun and the nearest star in Sagittarius constellation. It is located only 5. The star is a relatively young one, with an estimated age of less than a billion years.
It is a known X-ray source. It will make its closest approach to the Sun in about , years, when it comes within 6. Ross was originally catalogued by the American astronomer and physicist Frank Elmore Ross in It is classified as a UV Ceti-type flare star, one undergoing sudden dramatic increases in brightness for a few minutes. Flare stars are typically dim red dwarfs or less massive brown dwarfs.
V Sagittarii is the fourth known microquasar, discovered after four of the fastest X-ray intensity changes ever seen from a star. First detected in , V Sgr is a variable X-ray binary system once considered to be the closest black hole to Earth, at a distance of about 1, light years.
It is now believed to be located at least 15 times farther away. The system is notable for being the source of one of the most rapid superluminal faster than light jets in our galaxy. Located 38, light years away, the star is likely a binary system. It has an absolute magnitude of and a luminosity about 2 million times that of the Sun. Its estimated age is between 3 and 4. The star cannot be observed in visual bands because less than a billionth of its light in the visible spectrum reaches us, which translates to about 35th visual magnitude.
At the time of discovery, LBV was thought to be the most luminous and most massive star ever discovered. It has a mass of about 36 solar masses, which now puts it behind more than a dozen massive stars, including four members of the Arches Cluster. The soft gamma repeater SGR is a magnetar, a neutron star with an exceptionally strong magnetic field, more than 10 15 gauss 10 11 tesla in intensity , or quadrillion short scale times that of the Earth.
It is the most highly magnetized object ever discovered. The numbers indicate its position in the sky right ascension and declination. Artist conception of the December 27, gamma ray flare expanding from SGR Image: U Harvard. Soft gamma repeaters SGR are objects that emit enormous bursts of gamma-rays and X-rays at irregular intervals. They are believed to be a type of magnetar. SGR was identified as a soft gamma repeater in It lies at an estimated distance of 50, light years from Earth on the other side of our galaxy.
On 27 December, , the brightest gamma ray burst ever detected outside the solar system was recorded emanating from the star, with an absolute magnitude of about The burst was a result of a starquake, during which the magnetar released more energy in a tenth of a second than our Sun does in , years.
The Terebellum is a quadrilateral formed by four fourth magnitude stars in Sagittarius, all within two degrees of each other: Omega Sagittarii, 59 Sagittarii, 60 Sagittarii and 62 Sagittarii. Omega Sagittarii is a G-type subgiant marking the northeast corner of the Terebellum, about 78 light years distant from Earth. The star is classified as an irregular variable.
The stars are located at different distances from the solar system and are not gravitationally bound. Sagittarius A is a radio source located at the centre of the Milky Way, in the direction of the Sagittarius constellation. The supernova remnant Sagittarius A East is about 25 light years wide and appears to have originated in an event that occurred between 35, and , years ago.
During this time the black hole flared up in X-ray intensity half a dozen or more times. The cause of these outbursts is not understood, but the rapidity with which they rise and fall indicates that they are occurring near the event horizon, or point of no return, around the black hole. Baganoff et al. Because it has an imposing size and energy, Sagittarius A East is believed to be a remnant of a star that came close to the central black hole and was gravitationally compressed.
The spiral structure Sagittarius A West appears like a three-arm spiral and is sometimes called the Minispiral. It does not really have the structure of a spiral. The clouds have an ionized surface. Stars orbit the object at speeds greater than those of any other stars found in the Milky Way.
Sagittarius B2 is a very large molecular cloud of dust and gas approximately light years from the centre of the Milky Way. It has a mass three million times that of the Sun. The Lagoon Nebula is a large interstellar cloud classified as an emission nebula. It is one of the several notable H II regions in Sagittarius. It has an apparent magnitude of 6. Messier 8 is one of only two nebulae that are star forming regions and can be seen by unaided eye. It was first discovered by the French astronomer Guillaume Le Gentil in This giant cloud of gas and dust is creating intensely bright young stars, and is home to young stellar clusters.
This image is a tiny part of just one of eleven public surveys of the sky now in progress using ESO telescopes. Together these are providing a vast legacy of publicly available data for the global astronomical community. At the centre of the Lagoon Nebula, there is a structure known as the Hourglass Nebula not the same object as the famous Hourglass Nebula , which is located in the constellation Musca. The Hourglass Nebula contains several Herbig-Haro objects, small patches of nebulosity indicating that there are newly born stars in the vicinity, and providing direct evidence of star forming activity in the region.
