tulsaworld.com A10 SUNDAY, FEBRUARY 10, 2019 TULSA WORLD SKYWATCH Sunday: The International Space Station makes a high bright pass through the sky this evening. The space station begins its journey in the northwest at 6:29 p.m. Three minutes later, the spacecraft passes almost directly overhead. At 8:33 p.m., the ISS passes by the bright star Betelgeuse in Orion, and a minute later, it passes the even brighter star Sirius in Canis Major. The space station then continues to the southeast sinking lower in the sky. Tonight, the moon is 8 degrees below Mars. For the next few evenings, Mars and Uranus will be within 2 degrees of each other. The bright moonlight means you will need binoculars to locate Uranus. It will be to the lower left of Mars and both will easily fit in the same field of view. Uranus will appear as a bright point of light but about 100 times fainter than Mars. When the International Space Station appear this evening, it will not be as high as Sunday's pass, but it will be visible for a long time. At 6:23 p.m., the ISS is 10 degrees above the westnorthwest horizon. The space station slowly climbs higher, eventually reaching a height of 32 degrees in the southwest at 6:26 p.m. The spacecraft will slowly sink lower in the sky, and by 6:29 p.m., it is low in the south-southeast. Tonight, the moon is in the middle of the Hyades star cluster and close to the bright star Aldebaran. Aldebaran marks the red eye of Taurus the Bull, which stares at Orion the Hunter in the southeast. The evening sky is full of red. In the west is Mars, which has faded since fall, but this has deepened its reappearance. The giant red star Aldebaran, marking the eye of Tarsus the Bull, is due south at 7:30 p.m. Finally, the brightest of all is Betelgeuse in the shoulder of Orion, a star so large it would engulf all the planets in our solar system out to Jupiter. Monday: Tuesday: This artist's impression of the Milky Way shows the warped and twisted edges. Scientists in China and Australia used 1,339 pulsating stars to map the galaxy's shape. XIAODIAN CHEN/Chinese Academy of Sciences via AP Wednesday: Thursday: Friday: To the west of the constellation Taurus the Bull is the constellation Aries the Ram. Aries will be 45 degrees above the western horizon at 8 p.m. The brightest star in the constellation is Hamal. From Hamal, move 4 degrees to the west, then 1½ degrees to the southwest to Mesarthim, or Gamma Arietis. Gamma Arietis is a double star only distinguishable as two stars when viewed through a telescope. Spring training begins for most baseball teams next week. If you look to the west early tonight you can spot a baseball diamond low in the west. The baseball diamond will soon be setting and will not return until the summer. However, this diamond in the sky is actually the Great Square of Pegasus, the body of the mythical winged horse. Saturday: As of Wednesday, NASA hasn't heard from the briefcase-size twin Mars Cube One spacecraft for more than a month — and doubts it ever will. They shadowed NASA's InSight lander to Mars in 2018. NASA/JPL-Caltech via AP — Chris Pagan
