By measuring the amount of redshift, astronomers can determine how far away a given galaxy is. A map of 220,000 galaxies produced by the 2dF Galaxy Redshift Survey Team shows the universe has a filamentary structure, seen when it is considered on a large scale. Gallery: 65 All-Time ...
In a new study, astronomers show how gas expelled in the merger of two small galaxies can linger across vast distances for billions of years, where it may eventually feed gas to more massive galaxies to make new stars. The Large Magellanic Cloud and the Small Magellanic Cloud pictured above ...
What Kinds of Galaxies Are There? Astronomers classify galaxies into three major categories:elliptical, spiral and irregular. Who discovered galaxies? The first galaxies were identified in the 17th Century bythe French astronomer Charles Messier, although at the time he did not know what they were....
They know, for example, that dark matter behaves differently than "normal" matter, such as galaxies, stars, planets, asteroids and all of the living and nonliving things on Earth. Astronomers classify all of this stuff as baryonic matter, and they know its most fundamental unit is the atom,...
“Another cause is galaxy mergers, which can see two or more spiral galaxies crashing together to form one large elliptical galaxy in the aftermath.” The study utilized the powerful EAGLE simulations to analyze a group of galaxies in detail, using an AI algorithm to classify galaxies...
How do scientists classify stars? How is the Hubble Space Telescope serviced? How do astronomers use Hubble's law? How did the Kepler Space Telescope work? How does the Kepler Space Telescope work? How do astronomers know that some stars are binary stars?
Over the years, astronomers have developed many classification systems for stars, planets, galaxies, asteroids, meteorites, and comets. But no overall umbrella system has existed for all objects in the universe — until now! The Three Kingdom system I put forth below represents just that, a fra...
The one question for which we still do not have an answer is the question of the origin of the universe. In the final chapter, the author looks at the connection between science and philosophy and shows how new scientific results have laid the groundwork for the first serious scientific ...
Ghostly galaxy without dark matter baffles astronomers Unknown physics may help dark energy act as 'antigravity' throughout the universe Most of the mass of a cluster of galaxies, and the thing that really keeps them gravitationally bound, doesn't come from the galaxies or gas that we can dete...
