Iguana On Mars
2013-11-08 13:44:21

Lee Rannals for redOrbit.com - Your Universe Online A UFO hunter claims to have discovered an iguana on Mars in the shape of a rock using photos taken by NASA’s Curiosity rover. A YouTube user going by the name of UFO HuntingClouds posted a video this week on YouTube displaying a photograph of rocks taken on the surface of Mars earlier this year. The rock featured in the top right of the image has a very-vague resemblance to what could be a fossilized iguana, and it is sparking some...

Curiosity Takes Sharpest Images Yet Of Solar Eclipse On Mars
2013-08-29 11:20:58

Lee Rannals for redOrbit.com - Your Universe Online NASA said its Curiosity rover has taken the sharpest image of a solar eclipse ever taken on Mars. The Martian rover was able to snap an image of Phobos, the largest of Mars' moons, passing in front of the sun. Curiosity snapped a set of three frames, taken three seconds apart using its Mast Camera (Mastcam). The rover took a break from driving on August 17, 2013 in order to record the event. The images are the first full-resolution...

Mars Moons Double Eclipse
2013-08-16 13:00:26

Brett Smith for redOrbit.com - Your Universe Online NASA has just released a series of images from its Curiosity rover depicting Mars’ largest moon, Phobos, passing in front of its smaller counterpart Demios. The images have been assembled into a video available on the space agency’s website. Taken from the surface, the images clearly show large craters on Phobos and will be used to refine knowledge of the moons’ orbits around Mars. They mark to the first time the two moons have...

Martian Meteorite Age Puzzle Solved
2013-07-25 04:47:27

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Occasionally, a meteorite is found on Earth with peculiar origin: Mars. Anytime a large object such as an asteroid or comet impacts the surface of Mars, chunks of rock are ejected into outer space. Over time, some of these stones will make their way to Earth, impacting the ground as meteorites. We know that these specimens are from Mars based on their composition and other factors. So they provide an excellent laboratory for...

Curiosity Rover Longest Drive To Date
2013-07-24 10:05:43

Brett Smith for redOrbit.com - Your Universe Online In its continuing mission to survey Mars, NASA's Mars Curiosity rover drove its farthest distance ever on Sunday, the space agency said. NASA engineers took advantage of the rover's previous high vantage point to take Curiosity out for a spin at the start of its 340th Martian day, or sol. The Curiosity team said they will begin using the rover's automatic navigation, or "autonav," program to trace a path across the landscape and drive...

Martian Snowstorms Can Be Forecast Weeks Before They Occur
2013-05-09 09:43:53

April Flowers for redOrbit.com - Your Universe Online A new study from an international group of researchers led by the Max Planck Institute for Solar System Research (MPS) reveals that snowstorms that lash the northern hemisphere of Mars during the harsh winters may be predicted several weeks in advance. The team´s calculations reveal a connection between the snowfalls and a weather phenomenon special to Mars: fluctuations of pressure, temperature, wind speeds and directions that...

Spanish Team Says Russian Meteorite Originated From Apollo Asteroid Group
2013-02-26 10:01:50

Lawrence LeBlond for redOrbit.com - Your Universe Online The Chelyabinsk meteorite that exploded over Russia´s Ural Mountains region on Friday, February 15, has had its origins mapped by scientists. Initially, albeit wrongfully, some attributed the meteoric event to that of another celestial event that occurred on the same day: the close Earth flyby of asteroid 2012 DA14. After looking at amateur video footage, a group of researchers from Colombia were able to plot out the...

Mars' Moons Vs. Earth’s Moon
2013-02-18 09:19:35

Rayshell Clapper for redOrbit.com — Your Universe Online Earth has one moon, and it is considerably larger than Pluto. In fact, the relative size of Earth´s moon is quite massive compared to the moons of other planets. We have a fascination with our moon on many levels. But what if Earth had two moons as Mars does? According to NASA, unlike Earth´s moon, Mars moons are two of the smallest in the entire solar system. Mars moons also have proper names: Phobos and...

Earth To Mars, Just How Far Is It?
2013-02-11 08:41:26

Alan McStravick for redOrbit.com - Your Universe Online If you´ve ever had an inquisitive child ask you how far Mars is from Earth and you were unsure how to answer then, you are not alone. On their individual courses around our Sun, Mars and Earth follow an elliptical orbit. Imagine two race cars traveling on two different tracks at differing speeds. This analogy helps you visualize how sometimes these two planets are close together while at other times they are, quite literally,...

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...

Perseids Meteor Shower -- Like most meteor showers, the Perseids are caused by comet debris. As comets enter the inner solar system, they are warmed by the sun and peppered by the solar wind, which produces the familar tails that stretch across the night sky when a bright comet is close to Earth. Comet tails are made of tiny pieces of ice, dust, and rock which are spewed into interplanetary space as they bubble off the comet's nucleus. When Earth encounters these particles on its...

The Moon -- The Moon is the largest satellite of the Earth, and is occasionally called Luna (Latin for moon) to distinguish it from the general use of the word "moon". The Moon is distinguished from the satellites of other planets by its initial capital letter; the other moons are described in the natural satellite article. The words moon and month come from the same Old English root word. The Moon makes a complete orbit of the celestial sphere about every four weeks. Each hour the...

The Planet Mars -- in astronomy, 4th planet from the sun, with an orbit next in order beyond that of the earth. Physical Characteristics Mars has a striking red appearance, and in its most favorable position for viewing, when it is opposite the sun, it is twice as bright as Sirius, the brightest star. Mars has a diameter of 4,200 mi (6,800 km), just over half the diameter of the earth, and its mass is only 11% of the earth's mass. The planet has a very thin atmosphere consisting...

Mars' Moon Phobos -- in astronomy, innermost moon, or natural satellite, of Mars. Phobos orbits Mars at a distance of only 9,378 km (5,627 mi), closer to its planet than any other moon in the solar system. In fact, it is so close that the force of Mars's gravity is stronger than the force keeping the moon in its orbit, so the radius of Phobos's orbit is decreasing at the rate of about 1.8 m (about 6 ft) per century. In 40 million years, Phobos will either break apart into a ring...
