Latest Astronomy on Mars Stories
Scientists at NASA said they are busy prepping for observations of a comet that is expected to streak across the Martian sky. The comet is expected to pass about 10 times closer to Mars than any identified comet has ever flown by Earth.
The Quadrantids meteor shower will be helping to kick off the new year with a bang, displaying up to 80 meteors per hour on Friday.
Call it the geological equivalent of a buy-one, get-one free special: a planned Russian mission to collect samples from the Martian moon Phobos could also net debris from the Red Planet itself.
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.
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.
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.
Occasionally, a meteorite is found on Earth with peculiar origin: Mars. Anytime a large object, such as an asteroid or comet, impacts the surface 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.
In its continuing mission to survey Mars, NASA's Mars Curiosity rover drove its furthest distance ever on Sunday, the space agency said.
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.
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...
