None have been observed. It Martian houses do exist, they must be underground or very well concealed.

^ to the guy that posted above me. Nope, there are no houses. There maybe life-forms, but possibly tiny or invisible. Our technology is still in its advance stages

The Voyager 1 spacecraft is still traveling through space! Both Voyager 1 and 2 were sent to visit some of the planets of our solar system, but as there is no way to bring them back, they will continue to travel through the vast distances of space forever!

Both Voyager spacecraft are still communicating with the NASA team and will continue to do so as they have electrical power to operate some functions until 2020 (though they do not power their cameras anymore).

After 2020 the Voyager crafts will run out of power (so this will be about 43 years after they were launched) and be forever silent and continue on their endless journey through space for billions of years to come.

I don't know, I read somewhere that it was Tete, but I hope that big AI Jones is right, because that was my answer on some homework.

"Tete" was Eduard, Albert Einstein's second son, who was born in Zurich in 1910.

Mercury: Elliptical Venus: Elliptical Earth: Elliptical Mars: Elliptical Jupiter: Elliptical Saturn: Elliptical Uranus: Elliptical Neptune: Elliptical

All planets revolve around the Sun in elliptical orbits, with the Sun located at one of the two foci of the ellipse.

When you delete data from the recycle bin, the operating system marks the space occupied by that data as available to be overwritten. However, until new data is written in that space, the "deleted" data may still be recoverable using specialized software.

the earth rotates while moving around the sun. this be said, it wakes a day to revolve fully around the sun. while the earth is rotating, the angle of the sun changes, this has been learned a while ago, then we have sundials.

The three primary colors of light are red, green, and blue. When combined in different combinations and intensities, these colors can create a wide array of other colors through the process of additive color mixing.

An advantage of being a paleontologist is the fact that you get to learn about living things from long ago. One disadvantage is the fact that you may not discover something for years.

Matter's property depends on how it's molecules are interacting(if they move,or not).The four properties of matter are solid,liquid,gas,and plasma.A solid matter's molecules don't move apart,yet the other three do.Liquid molecules do move apart ,but not by much.Gas molecules will move apart as far as they can.Plasma takes it even farther,the electrons in it even move apart from the rest of the molecule.

A scientist who studies fish is called an ichthyologist. Ichthyologists examine the biology, ecology, behavior, and evolution of fish species in both freshwater and marine environments. They often focus on aspects such as anatomy, physiology, and conservation of fish populations.

A variation in a landscape is called topography, which refers to the natural features and characteristics of the land, such as hills, valleys, mountains, and bodies of water. Topography plays a significant role in shaping the overall appearance and function of a landscape.

umm, its 4. Periods are horizontal lines on the periodic table of elements.

In debut celebrations, 18 balloons may symbolize the celebrant's transition into adulthood or coming of age, as it signifies the age of 18 which is often associated with reaching legal adulthood in many cultures. The balloons may serve as decorations to represent this milestone and mark the beginning of a new chapter in the celebrant's life.

A bee is considered a matter because it is a physical object composed of atoms and molecules.

In the southern hemisphere, the December solstice occurs around December 21st. This is known as the summer solstice in the southern hemisphere and marks the longest day of the year with the shortest night, as it is when the sun reaches its highest position in the sky.

Whiskey is made from a fermented grain mash, typically including barley, corn, rye, and wheat. The mixture is distilled to extract alcohol, then aged in wooden barrels to develop flavor and color. Water may be added to adjust the final alcohol content.

Telescopes use lenses to view objects millions of kilometers away in space. These lenses help to collect and focus light from distant objects, allowing astronomers to observe planets, stars, galaxies, and other celestial bodies with great detail and clarity.

Distilled water is used in pollen germination experiments because it is free from impurities and contaminants that could potentially affect the results of the experiment. By using distilled water, researchers can ensure that any growth or changes observed in the pollen are solely due to the experimental conditions being studied.

The Big Dipper constellation has been known and observed for thousands of years by various cultures around the world, so there is no definitive answer to who discovered it. It has been a prominent feature in the night sky and has been used for navigation and storytelling throughout history.

Scientists classify jaguars, ocelots, and lynx in the same family based on similarities in their physical characteristics, behavior, and genetic relatedness. These animals share common traits such as a similar body structure, fur patterns, and hunting behaviors, which indicate their evolutionary relatedness within the Felidae family.

NASA launched a robotic spacecraft called New Horizons (See links below) in January 2006. It is expected to reach Pluto in July 2015. It will have taken nine and a half years to get from Earth to Pluto.

IAU stands for the International Astronomical Union, an organization that is responsible for promoting and coordinating the international collaboration in astronomical research. It is also responsible for assigning official names to celestial bodies and features.

Members of a group that can interbreed and produce fertile offspring are in the same? it is known as a species
