It is said that when the star’s brightness increases, this marks the beginning of initiation rites, when young men must stay away from women. In 2013, high spectral resolution imaging of the star’s atmosphere found an outer atmosphere between 1.2 and 1.4 R⋆, an effective temperature of 3,660 ± 120 K, and a mass of 15 ± 5 solar masses, with an estimated age between 11 and 15 million years. This is significantly cooler than our sun's chromosphere, which is almost 36,032 degrees F (20,000 degrees C). into an amulet. In ancient Greece, Antares was called Καρδία Σκορπίου (Kardia Skorpiū), meaning “the heart of the scorpion.” The name was translated into Arabic as Calbalakrab, derived from the phrase Qalb al-Άqrab. It has run out of its supply of hydrogen and is currently burning through progressively heavier elements.

Like Betelgeuse in Orion, it may explode as soon as in the next 10 thousand years or at some point in the next million years. Its luminosity is dimmed by interstellar dust, but the degree of dimming is uncertain. Antares is one of the 27 stars represented on the flag of Brazil. The globular cluster NGC 6144 is considerably smaller and fainter, but lies closer to Antares. The Māori people of New Zealand know the star as Rēhua, a sacred figure who lives in the highest of heavens, cannot die and has the power to heal any illness and revive the dead. An artist's impression of the atmosphere of the supergiant star Antares. 1.62), Sargas (Theta Sco A, mag. [1] The star is so large, that its diameter was calculated using its parallax, and angular diameter, which lead to a radius of 822±80 that of our Sun. However, the explosion will not affect Earth because Antares is too distant. The very colourful Rho Ophiuchi and Antares region features prominently to the right, as well as much darker areas, such as the Pipe and Snake Nebulae. Waiyungari followed the emus until the women revealed themselves and seduced him. Get breaking space news and the latest updates on rocket launches, skywatching events and more! This is the most detailed image ever of this object, or any other star apart from the Sun. The primary star, Antares (also called Antares A), is a class M1.5Iab-b supergiant. Scorpius constellation, image: Roberto Mura. Its ancient Chinese name was 心宿二 (Xīnxiù’èr), or the Second Star of Heart. as one of the four royal stars. Antares is one of the two stars in the constellation Scorpius selected for navigation. With an average apparent magnitude of 0.96, it is the brightest star in Scorpius and usually the 15th brightest star in the sky. [5] If the star was at the center of our solar system, it would extend to between the orbits of Mars and Jupiter. "The longer wavelengths of the VLA revealed the supergiant's atmosphere out to nearly 12 times the star's radius.". A 2009 study of long secondary periods in pulsating red giants did not find a separate long secondary period in Antares. It has an apparent magnitude of 9.63 and an apparent size of 1′.8. Interesting fact. The name Antares (pronunciation: /ænˈtɛəriːz/) comes from the Ancient Greek Ἀντάρης, meaning “rivalling Ares.” The name refers to the star’s similarity to the planet Mars due to its reddish appearance. Surface temperature. The cluster appears quite large, occupying an area of 26′, and has an apparent magnitude of 5.9.

The Ngarrindjeri people of southern Australia associated Antares and its variability with the myth of Waiyungari (“red man”). While the star’s physical radius could be derived from its angular size and distance, its exact distance is uncertain, which makes the exact size difficult to pinpoint. Antares is referenced in the graphic novels in the Antares series (2007—2011) by Luiz Eduardo de Oliveira and the Japanese manga series Saint Seiya. Antares has the stellar classification M1.5Iab-Ib, indicating a supergiant star appearing distinctly red in colour. The Wotjobaluk people of the state of Victoria associated Antares with Djuit, son of Marpean-kurrk, a female ancestral figure represented by Arcturus. Luminosity- Antares' luminosity is 10,000 times that of the sun. The Orionid meteor shower peaks this week! Antares B has a luminosity roughly 170 times that of the Sun. Related: These weirdo stellar corpses have creamy centers filled with exotic quantum liquids, "The size of a star can vary dramatically depending on what wavelength of light it is observed with," Eamon O'Gorman, a researcher at the Dublin Institute for Advanced Studies in Ireland and lead author of this study, said in a statement. Antares surface temperature is about, 3,500 kelvins. The 10 brightest stars in Scorpius are Antares (Alpha Sco A, mag. The comparison of the two possibly dates back to early Mesopotamian astronomy. The last occultation, by Venus, was recorded on September 17, 525 BCE, and the next one will occur on November 17, 2400. It is said that Orion and the scorpion were placed at the opposite ends of the sky and the two constellations never appear above the horizon at the same time because Orion is still fleeing from the scorpion.

The exact size of Antares is uncertain, but its estimated radius is between 680 and 800 solar radii. A 2012 study of stars belonging to the Scorpius-Centaurus OB association calculated an initial mass of 17.2 solar masses and an age of 12 million years (allowing for a margin of error in the range from 11 to 15 million years) for Antares. This dark lane also hosts the very center of our Galaxy, where a supermassive black hole is lurking. The existence of the companion, Antares B, was first reported by the Austrian astronomer Johann Tobias Bürg, who observed Antares during a lunar occultation that occurred on April 13, 1819. With a J-band magnitude of -2.7, it outshines R Doradus (-2.6), Arcturus (-2.2) and Aldebaran (-2.1), but is not quite as bright as Betelgeuse (-2.99). (Image credit: NRAO/AUI/NSF, S. Dagnello). The star does not have a clear period, but a study published in 2006 that analysed the AAVSO data over the last century suggested a period of 1650 ± 640 days. Antares reaches its highest point in the sky at dawn in early March and at sundown in early September. Here's what to expect. The best time of year to observe the stars and deep sky objects of Scorpius is during the month of July, when the constellation is prominent in the southern sky. The others are Aldebaran in Taurus, Regulus in Leo and Spica in Virgo. Antares is a member of the Upper Scorpius subgroup of the Scorpius-Centaurus Association (Sco OB2), the nearest OB association to the Sun. Since evolving away from the main sequence, Antares has expanded to a size of 680 to 800 solar radii. The star’s properties are just as challenging to pin down as those of Antares, but with an estimated radius between 887 and 955 solar radii, Betelgeuse is somewhat larger than Antares and, at a distance between 640 and 724 light years from Earth, it is also more distant. These tour de force observations bring the universe close, right into our own backyard," Chris Carilli of the National Radio Astronomy Observatory, who was not involved in this study but who was involved in the first observations of Betelgeuse at multiple radio wavelengths with the VLA in 1998, added in the same statement.
