Or something, such as gravity, that can mimic some of the light bending attributes of a physical lens. Lens: (such as glass) that bends incoming light in such a way as to focus it at a particular point in space. This planet also releases more heat than it receives from the sun as gravity compresses its mass (and slowly shrinks the planet). A gas giant, its low density indicates that this planet is composed mostly of the light elements hydrogen and helium. Jupiter: (in astronomy) The solar system’s largest planet, it has the shortest day length (9 hours, 55 minutes). Aquatic organisms called diatoms build their shells of it. Glass usually is transparent and fairly inert (chemically nonreactive). Glass: A hard, brittle substance made from silica, a mineral found in sand. Gamma rays are the most energetic form of light. Gamma rays: High-energy radiation often generated by processes in and around exploding stars. (In vision, verb, "to focus") The action a person's eyes take to adapt to light and distance, enabling them to see objects clearly. Such an impact is sometimes referred to as a cratering event.įocus: (in physics) The point at which rays (of light or heat for example) converge sometimes with the aid of a lens. They are typically caused by an explosion or the impact of a meteorite or other celestial body.

The new James Webb Space Telescope is unveiling the most distant, early universe like we’ve never seen it before.Ĭheck out the full list of Scientists Say.Ītmosphere: The envelope of gases surrounding Earth, another planet or a moon.īlack hole: A region of space having a gravitational field so intense that no matter or radiation (including light) can escape.Ĭrater: A large, bowl-shaped cavity in the ground or on the surface of a planet or the moon. Using different types of telescopes to look at the same object can paint a more complete picture of that light source than any one telescope alone. Other telescopes are built to collect X-rays, gamma rays or ultraviolet light. This observatory has gotten the clearest views yet of the most distant parts of the universe. The new James Webb Space Telescope collects infrared light. Many radio observatories around the world worked together to produce the first image of a black hole. Huge ground-based dishes collect radio waves from space. Other telescopes look at different types of light. The Hubble Space Telescope is one example. Others are sent into space, where their views aren’t blurred by Earth’s atmosphere. Some large optical telescopes are housed in observatories on the ground. With it, you could view craters on the moon or the moons of Jupiter. You might set up this type of telescope in your backyard. They do this using glass lenses or mirrors. Optical telescopes gather and focus light mainly from the visible part of the spectrum. Much of what we know about the universe comes from telescope observations. Some telescopes even collect types of light that the human eye cannot see.
In general, bigger telescopes collect more light and offer better views.
They collect and focus more light than our eyes could on their own. Telescopes are tools used to view distant objects.
