Studies show microbes can last in space over very short timescales, Metzger says. Scientists could test whether microbes in astronaut waste have survived or mutated over the past 50 years. That could help determine whether life could hop between planets or even solar systems. They spent nearly 22 hours on the moon. They collected a handful of rocks and other samples that were returned home for scientists to study.
Along the way, this program sought to develop the technologies needed for long-distance space travel.

It got a big kick-start after President John F. The term is also for the process of collecting and storing such things. People who perform this task are known as archivists. For example, water is a chemical made when two hydrogen atoms bond to one oxygen atom. Its chemical formula is H 2 O. Chemical also can be an adjective to describe properties of materials that are the result of various reactions between different compounds. Or, a long, tube-like sample drilled down into ice, soil or rock. Cores allow scientists to examine layers of sediment, dissolved chemicals, rock and fossils to see how the environment at one location changed through hundreds to thousands of years or more.
For digital information the type stored by computers , those data typically are numbers stored in a binary code, portrayed as strings of zeros and ones. Space debris, for instance, includes the wreckage of defunct satellites and spacecraft. Examples include hydrogen, oxygen, carbon, lithium and uranium. Also a term to describe a real-world environment in which some research is conducted, such as at sea, in a forest, on a mountaintop or on a city street.
It is the opposite of an artificial setting, such as a research laboratory. In vision, verb, "to focus" The action a person's eyes take to adapt to light and distance, enabling them to see objects clearly. Your parents belong to one generation of your family, for example, and your grandparents to another.
Similarly, you and everyone within a few years of your age across the planet are referred to as belonging to a particular generation of humans. The more mass that something has, the greater its gravity. Some journals publish papers from all fields of science, technology, engineering and math, while others are specific to a single subject.
The best journals are peer-reviewed: They send all submitted articles to outside experts to be read and critiqued.

The goal, here, is to prevent the publication of mistakes, fraud or sloppy work. Lasers are used in drilling and cutting, alignment and guidance, in data storage and in surgery. A living thing that is too small to see with the unaided eye, including bacteria, some fungi and many other organisms such as amoebas. Most consist of a single cell. Or an individual that is meant to display how something would work in or look on others. Created in , this U. It also has sent research craft to study planets and other celestial objects in our solar system. One complete circuit around a celestial body.
Quantum physics, a field of study that emerged later, is a more accurate way of explaining the motions and behavior of matter. A scientist who works in such areas is known as a physicist.
On the skin, substances such as oil, water and sweat pass through these openings. The other two are conduction and convection. In radiation, electromagnetic waves carry energy from one place to another. Unlike conduction and convection, which need material to help transfer the energy, radiation can transfer energy across empty space. It can permeate the solar system. This is called a stellar wind, when from a star other than the sun.
Stars develop when gravity compacts clouds of gas. When they become dense enough to sustain nuclear-fusion reactions, stars will emit light and sometimes other forms of electromagnetic radiation.

The sun is our closest star. Some, however, collect radio emissions energy from a different portion of the electromagnetic spectrum through a network of antennas. The term might refer to anything from a smooth, flat and dry landscape to a mountainous region covered with boulders, bogs and forest cover. It is about 1, kilometers miles long and covers an area of , square kilometers , square miles. A theory can also be a way of organizing a broad body of knowledge that applies in a broad range of circumstances to explain what will happen.
Unlike the common definition of theory, a theory in science is not just a hunch. Ideas or conclusions that are based on a theory — and not yet on firm data or observations — are referred to as theoretical. Laboratories or manufacturing plants may use vacuum equipment to pump out air, creating an area known as a vacuum chamber.
