Such contents comprise all of energy in its various forms, including electromagnetic radiation and matter, and therefore planets, moons, stars, galaxies, and the contents of intergalactic space. The universe also includes the physical laws that influence energy and matter, such as conservation laws, classical mechanics, and relativity.. The universe is often defined as "the ...

New ideas and major discoveries made during the 20th century transformed cosmology – the term for the way we conceptualize and study the universe – although much remains unknown. Here is the history of the universe according […]
Jul 4, 2024 · universe, the whole cosmic system of matter and energy of which Earth, and therefore the human race, is a part. Humanity has traveled a long road since societies imagined Earth, the Sun, and the Moon as the main objects of creation, with the rest of the universe being formed almost as an afterthought. Today it is known that Earth is only a small ball of rock in a space of unimaginable vastness and that the birth of the solar system was probably only one event among many that occurred against ...
Coming in Hot – NASA’s Chandra Checks Habitability of Exoplanets. Astronomers are using NASA’s Chandra Observatory and ESA’s (European Space Agency’s) XMM-Newton X-ray data to explore whether nearby stars could host habitable exoplanets by tracking how much lethal radiation the exoplanets receive in orbit.
May 3, 2022 · The universe is literally everything, the sum of all existence. It includes all matter, like stars and galaxies. The universe also includes all radiation and all other forms of energy.
Jun 2, 2023 · What Is the Big Bang? About 13.8 billion years ago, the universe sprang into existence in an event known as the big bang. The early universe was incredibly hot — too hot for even atoms to exist — and extraordinarily dense.
The Universe is everything we can touch, feel, sense, measure or detect. It includes living things, planets, stars, galaxies, dust clouds, light, and even time. Before the birth of the Universe, time, space and matter did not exist.
The universe is space and everything in it. It is made of many billions of stars and planets and enormous clouds of gas separated by big spaces. The Big Bang started the expansion of the universe.. WMAP image of cosmic background radiation. Astronomers use telescopes to look at distant galaxies.This is how they see what the universe looked like a long time ago. The past tense is because the light from distant parts of the Universe takes a very long time to reach us.
