Once opened, olive oil continues to remain usable for two years past its expiration date, while most other types of oil remain viable for one year. The exception to this is hazelnut oil, which should be used in three months, and sesame oil, which should be used within eight months of opening.
(Alpha Scorpii) Antares (meaning Rival of Mars) is the brightest star in Scorpius, one of the constellations in the zodiac. Antares is a M1.5Iab variable red supergiant starâ¦ that is about 520 light-years from Earth and is about 230 times as big as the Sun. This incredibly massive, old, low-temperature (3500 K) star is the 15th brightest star in the sky; it has a visual (apparent) magnitude of +0.96 (var.) and an absolute magnitude of -5.2.
Bottom line: The constellation Scorpius is easy to pick out with the eye, because it looks like its namesake. Prominent stars include Antares the Scorpionâs Heart, and Shaula and Lesath in the Scorpionâs Tail (The Stinger). The star cluster M4 can be seen right next to Antares. You can see M6 and M7 near the Scorpionâs Tail. In the lore of the sky, Scorpius is arch-enemy to Orion the Hunter.
