Latest Astronomy on Mars Stories
The Chelyabinsk meteorite that exploded over Russia’s Ural Mountains region on Friday, February 15, has had its origins mapped by scientists.
Earth has one moon, and it is considerably larger than Pluto. In fact, the relative size of Earth’s moon is massive compared to the moons of other planets. But what if Earth had two moons as Mars does?
Just how far is it from Earth to Mars? The answer may be a bit more complicated than you expect.
We are learning something new about the red planet almost daily. But what about the weather on our celestial neighbor? One of the most common questions that people have is whether Mars is hot or cold.
Stanford Researchers, working with NASA’s Jet Propulsion Laboratory (JPL) and MIT, have designed a new robotic platform that could be used to explore the moons of Mars.
Researchers say that if Curiosity ever loses its location on the surface of Mars, it could use eclipses to help it find its way.
According to a new study, scientific modeling methods that predicated climate change on Earth can also be used on Mars as well.
An international team of researchers is examining a meteorite that landed 14 months ago in the Moroccan desert for information about Mars. Traces of the Martian atmosphere were trapped in the Tissint meteorite.
Curiosity, at 54-days deep into its mission on Mars, recently shot back an image to NASA taken of an interesting rock called "Bathurst Inlet."
NASA's Curiosity rover has sent back a Martian weather report, showing surprisingly mild daytime temperatures.
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...
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
