astronomer: A scientist who works in the field of research that deals with celestial objects, space and the physical universe.
colleague: Someone who works with another; a co-worker or team member.
cosmic: An adjective that refers to the cosmos — the universe and everything within it.
environment: The sum of all of the things that exist around some organism or the process and the condition those things create. Environment may refer to the weather and ecosystem in which some animal lives, or, perhaps, the temperature and humidity (or even the placement of things in the vicinity of an item of interest).
insight: The ability to gain an accurate and deep understanding of a situation just by thinking about it, instead of working out a solution through experimentation.
journal: (in science) A publication in which scientists share their research findings with experts (and sometimes even the public). Some journals publish papers from all fields of science, technology, engineering and math, while others are specific to a single subject. Peer-reviewed journals are the gold standard: 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 work that is not novel or convincingly demonstrated.
life cycle: The succession of stages that occur as an organism grows, develops, reproduces — and then eventually ages and dies. Or the sum of all processes involved in creating a product, starting with the extraction of raw materials and ending with the disposal of the product when it’s no longer useful. Indeed, engineers describe this as the cradle-to-grave life of a product.
light-year: The distance light travels in one year, about 9.46 trillion kilometers (almost 6 trillion miles). To get some idea of this length, imagine a rope long enough to wrap around the Earth. It would be a little over 40,000 kilometers (24,900 miles) long. Lay it out straight. Now lay another 236 million more that are…
