The universe, on the other hand, is composed of the earth and everything we see around it and the outer space including all observable galaxies. The solar system is but part of our universe. The universe is believed to contain constantly evolving matter. It is composed of atoms, molecules,...
The physical scales used to measure time and space in the solar system, galaxy, and universe vary widely. Inferences can simplify comparisons and...
Therefore, the centre of the Galaxy is very, very far away. Galaxy vs. Universe A Solar System is the smallest of the three subject matter. It covers the area of a Star's Heliosphere. Inside is the star and all the orbiting Planets, Asteroids, etc. A solar system may not even ...

Planets beyond our solar system called "super-Earths" are common in the universe. Astronomers want to know if these worlds are habitable, and if any of them are like Earth. Instruments like the James Webb Space Telescope will peer into the atmospheres of
Similarly, the massive Sun creates a deep, but invisible dimple in the fabric of spacetime. The planets feel this ‘curvature of space’ and literally roll toward the Sun. Only their sideways motion or angular momentum keeps them from falling straight into the solar inferno. ...
An Exomoon is a moon that orbits a planet, not in our solar system. Although we've discovered thousands of worlds out there, we have yet to find an exomoon conclusively, but we do have candidates. What is an Irregular Galaxy? An Irregular Galaxy is a galaxy that doesn't fit into the...
“While there are many examples of this type of binary system, very few have the age constraints necessary to fully map their evolutionary history. While there is plenty of work left to confirm and fully characterize these systems, these results will have implications across multiple areas of ...
If it turns out to be true that it takes a galaxy of stellar "experiments" to produce just one (or a few) intelligent civilizations per galaxy, on average, that looks extremely wasteful and random (evolutionary) at the solar system scale, but simultaneously convergent and predictable (developme...
Astronomers have discovered one of the brightest quasars in the early universe: SDSS J0100+2802, powered by a supermassive black hole of 12 or 13 billion solar masses. Monster black hole in early universe However, these clusters have not always existed, and a key question in modern cosmology...
