Although they can not be seen individually, «the total light produced by these stray stars is about equal to the background light we get from counting up individual galaxies,» says Bock, also a senior research scientist at JPL.

These special classes of galaxy, so named for their extremely diffuse appearance, apparently produced far fewer stars than other galaxies or else were stripped of them long ago by galactic tidal forces.

They observed the galaxy using a special band - pass filter that selectively transmits the light around an emission line produced by ionized hydrogen (called the H - alpha emission line).

In other words, if you calculate the light produced by individual galaxies, you would find they made less than the background light.

«High - energy neutrinos are produced along with gamma rays by extremely high - energy radiation known as cosmic rays in objects like star - forming galaxies, galaxy clusters, supermassive black holes, or gamma - ray bursts.

Adding other data acquired by optical, radio, and x-ray instruments, the researchers made a stunning discovery: The galaxy, which they've nicknamed «Baby Boom,» was producing at least 4000 new stars per year, about 400 times more than the Milky Way is now.

«We are now fully confident that one of the most popular supernova remnants detected in our galaxy was produced by an ordinary type Ia supernova that was first detected more than 400 years ago,» write Andrea Pastorello of Queen's University Belfast and Ferdinando Patat of the European Southern Observatory in Germany in a commentary on the study.

The next step, he says, will be to go for confirmation by surveying many more galaxies — perhaps as many as 100 million — at different distances, meaning at different ages of the universe, to see if the effects produced by this first round remain consistent.

The astronomers observed an object called 1E0657 - 556, which was produced by two galaxy clusters that collided with one another 100 million years ago at 4700 kilometres per second.

Ray Jayawardhana: It is a clue that most likely, these high energy neutrinos come either from jets of particles that are accelerated by super massive black holes at the hearts of galaxies, or from really gigantic stars that explode at the end of their lives that also produce a phenomenon we call gamma ray bursts, which also might accelerate particles to very high speeds and energies.

«Seyfert» galaxies, which are all around us, are sort of miniquasars, producing a torrent of radiation from their core that, though it's far less than a quasar's, is spectacular by ordinary galactic standards.

The bursts come from all directions, suggesting that they are produced by violent events in other galaxies.

Galactic magnetic fields, they suggest, are produced by a ring of electrically charged gas rotating around a giant black hole at the center of a galaxy.

Zemcov et al. sent up a rocket to measure the fluctuations in this faint background and found largescale fluctuations greater than known galaxies alone should produce (see the Perspective by Moseley).

Image of a galaxy (center) with incoming cold gas flow, produced by rendering the gas distribution in a supercomputer simulation of a forming galaxy.

The large velocities of the galaxies in the clusters are produced by more gravity force than can be explained with the gravity of the visible (either shining or blocking light) matter in the galaxies.

These are expected to have become rapidly enshrouded in the dust produced by the first stars; the dust absorbs much of the starlight making the galaxies difficult to see in the optical wavebands, but these same galaxies shine brightly at millimeter and submillimeter wavelengths.

But the astronomers were able to detect them by using a natural zoom lens in space, produced by the gravity of Abell 1689, a giant foreground galaxy cluster.

The light from these active galaxies is produced by a strange process in the centers of the galaxies.

Mauna Kea, HI — A team of scientists led by astronomers at the University of California, Riverside has used NASA's Hubble Space Telescope and the W. M. Keck Observatory to uncover the long - suspected underlying population of galaxies that produced the bulk of new stars during the universe's early years.

Inspired by some of the images taken by the Faulkes Telescopes, Year 3 pupils produced some beautiful chalk drawings of galaxies, nebulae and various other astronomical objects.

Light at characteristic wavelengths is produced by gas molecules in these galaxies, and the wavelengths are stretched by the expansion of the Universe over the billions of years that it takes the light to reach us.
