An active galaxy has an unusually bright and variable center powered by a supermassive black hole that heats a surrounding disk of gas and dust through gravitational and frictional forces. The black hole slowly consumes the material around it, which creates random fluctuations in the disk's emitted light. As with most active galaxies, NGC 4945's black hole and disk are shrouded by a dense.

Characteristics The constellation of Orion, as it can be seen by the naked eye. Lines have been drawn. Orion is bordered by Taurus to the northwest, Eridanus to the southwest, Lepus to the south, Monoceros to the east, and Gemini to the northeast. Covering 594 square degrees, Orion ranks twenty-sixth of the 88 constellations in size.

Galaxies ESA Galaxies Until the 1930s, galaxies were not known as such, but as patches of stars residing in our galaxy. But when the distance to these patches was discovered, it quickly became apparent that they were a new type of object.

NGC 2207 and IC 2163 are a pair of colliding spiral galaxies about 80 million light-years away [2] in the constellation Canis Major. Both galaxies were discovered by John Herschel in 1835. The larger spiral, NGC 2207, is classified as an intermediate spiral galaxy exhibiting a weak inner ring structure around the central bar.

Une étoile est un objet céleste (se trouvant dans l'univers) qui est visible dans le ciel. Il s'agit d'une boule qui crée sa propre lumière tellement elle est chaude. Celle-ci est formée de gaz. Elle est aussi très lourde. En effet, elle pèse en moyenne dix milliards de milliards de milliards de milliards de tonnes.

Astronomers shed light on different galaxy types Astronomy Now
Audio. Astronomers have identified the main driver of star formation over 10 billion years by looking at 95 galaxy clusters. These galaxy clusters are some of the brightest and most massive known, ranging in distance from 3.4 to 9.9 billion light-years from Earth. Remarkably the primary factor in vigorous stellar birth is whether vast amounts.

Constellations are groups of stars that form patterns in the night sky, often named after animals, creatures, or mythological people resembling the outline or pattern. The word 'constellation' comes from the Latin 'constellacio' which means 'set of stars'. Of the billions of stars in the universe, only a fraction make up the shapes.

The Short Answer: There are a few different definitions of constellations, but many people think of constellations as a group of stars. The constellations you can see at night depend on your location on Earth and the time of year. Constellations were named after objects, animals, and people long ago.

A constellation is a group of stars that appear to make a pattern in the sky. When we look at them they look close together but in reality they are usually very far apart and not grouped together in space. An asterism is a pattern either in a constellation such as 'The Plough' in Ursa Major or made up of brighter stars connecting constellations.

The main difference between constellation and galaxy is that constellation is a recognized pattern of stars in the night sky, while a galaxy is a system of billions of stars, together with gas and dust, held together by gravity. Both terms constellation and galaxy are related to stars, but constellations are not real objects while galaxies are.

Spiral Galaxies = shaped like a flat disc with a bulge in the center. Long, twisted arms that rotate around the center like a pin wheel. Usually contain large amounts of gas and dust. Ex.-. The Milky Way Galaxy. 3. Barred Spiral Galaxies = arms are attached to a straight-bar shape. Bar is much brighter than the arms.

A constellation is a recognizable pattern of stars in the night sky, while a galaxy is a system of billions of stars and their solar systems, gas, and dust, held together by gravity. The constellation is an imaginary pattern, while the galaxy is a real concept. 'It is constellation, which causeth all that a man doeth.';

Centaurus A is the fifth brightest galaxy in the sky — making it an ideal target for amateur astronomers — and is famous for the dust lane across its middle and a giant jet blasting away from the supermassive black hole at its center. Cen A is an active galaxy about 12 million light years from Earth. This image is part of a " quartet of.
