Latest Astronomy on Mars Stories
Even a shallow ocean, about 50 meters deep, would be enough to keep such a planet at relatively comfortable temperatures, averaging around 60 degrees Fahrenheit year-round.
WASHINGTON, Nov. 7, 2014 /PRNewswire-USNewswire/ -- Two NASA and one European spacecraft that obtained the first up-close observations of a comet flyby of Mars on Oct.
On October 19, 2014, Comet Siding Spring will pass by Mars only 132,000 km away - which would be like a comet passing about 1/3 of the distance between Earth and the Moon.
3,500 million years ago the Martian crater Gale, through which the NASA rover Curiosity is currently traversing, was covered with glaciers, mainly over its central mound.
WASHINGTON, June 23, 2014 /PRNewswire-USNewswire/ -- NASA's Mars Curiosity rover will complete a Martian year -- 687 Earth days -- on June 24, having accomplished the mission's main goal of
While the average planet-wide temperature on Mars is a frigid -81 degrees F and the lowest winter temperatures can get down to -184 degrees F, the Red Planet is much more hospitable than those temperatures would suggest due to a lack of wind chill.
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.
Dust is everywhere on Mars, and plays a key role in the red planet’s weather, according to a Texas A&M University researcher who has spent much of the past decade observing the phenomenon.
It’s the mystery that has space enthusiasts and the blogosphere buzzing: what exactly is the flash of light that appears on photos taken by NASA’s Mars Curiosity rover earlier this month?
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.
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...
