mars sees mercury transit
2014-06-11 09:14:23

Brett Smith for redOrbit.com - Your Universe Online Observers on Earth have tracked Venus and Mercury crossing the face of the Sun countless times, but the phenomenon has never been observed from another planet – until now. On Tuesday, NASA announced that its Curiosity Rover had captured the first-ever observations of Mercury moving across the face of the Sun – also called a planetary transit – using its two-eyed Mast Camera (MastCam). "This is a nod to the relevance of...

Science China Press As a kind of ground-based optical astrometric instrument, zenith telescope observes stars near zenith, which substantially reduces the influence of normal atmospheric refraction. Its high-precision observations can be used to calculate astronomical latitude and longitude, which are mainly applied in mobile measurement for deflection of the vertical, long-term measurement for the variations of the vertical, and related researches of astronomical seismology. Utilizing CCD...

Stellar Tape Measure
2014-04-11 05:13:14

NASA Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away -- 10 times farther than previously possible. Astronomers have developed yet another novel way to use the 24-year-old space telescope by employing a technique called spatial scanning, which dramatically improves Hubble's accuracy for making angular measurements. The technique, when applied to the age-old method for gauging distances called astronomical...

ESA's Gaia Mission Is Beginning To See Things More Clearly
2014-02-06 13:37:15

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency’s (ESA) billion-star surveyor mission is slowly beginning to see more clearly. ESA’s Gaia launched on December 19, 2013, and since then it has been preparing for its mission to gather loads of data on stars that surround us. Gaia took a test image of a dense cluster of stars in the Large Magellanic Cloud as part of a “fine tuning” test to get the spacecraft into focus. The new image is allowing ESA...

Hubble Images Variable Star's Light Echo
2013-12-18 04:42:49

[ Watch the Video: Light Echoes Around RS Puppis ] redOrbit Staff & Wire Reports - Your Universe Online Observations from the NASA/ESA Hubble Space Telescope, collected over the span of five weeks, show the variable star RS Puppis growing alternately brighter and dimmer – a phenomenon known as a light echo. Hubble monitored RS Puppis, which is ten times more massive and roughly 15,000 times more luminous than the sun, and captured it at different stages throughout its...

Planetary Dance In The Sunset Sky
2013-05-24 04:15:11

[ Watch the Video: ScienceCasts: Sunset Triangle ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Fans of stargazing are in for a treat this weekend. Over the next several days the planets, Venus, Jupiter, and Mercury will approach each other in the fading sunlight to form a triple conjunction — where three bodies appear to converge in the sky. The events will culminate on the evening of the 26th, and will appear to form a triangle just above the horizon....

Methuselah Star Birth Certificate
2013-03-08 08:38:30

April Flowers for redOrbit.com - Your Universe Online The ink is drying on a brand new birth certificate for a star that's been around for a very long time. New calculations using NASA'S Hubble Space Telescope have enabled a group of astronomers to take an important step closer to reconciling the age of this star, and the age of the Universe. "We have found that this is the oldest known star with a well-determined age," said Howard Bond of Pennsylvania State University in University...

Positional Astronomy -- Positional astronomy is the study of the positions of celestial objects. This is the oldest branch of astronomy and dates back to antiquity. Observations of celestial objects are important for religious and astrological purposes, as well as for timekeeping. Ancient structures associated with positional astronomy include: -- Chichn Itz -- The Medicine Wheel -- The Pyramids -- Stonehenge -- The Temple of the Sun The unaided human eye can...

The Planet Venus is the second planet from the sun. It is often called the evening star or morning star and is brighter than any object in the sky except the sun and the moon. Because its orbit lies between the sun and the orbit of the earth, Venus passes through phases like those of the moon, varying from a large bright crescent when the planet is near inferior conjunction (nearest the earth) to a smaller silvery disk when it is at superior conjunction (farthest from the earth). Since...
