Alternative «warm dark matter» models of cosmic structure — in which galaxy formation was seeded by lighter, faster - moving particles that would not have clumped together as readily as cold dark matter — could eliminate the need for the missing galaxies.

So a galaxy moving away from Earth, in addition to being carried along by cosmic expansion, will have an extra redshift and appear farther from us than it actually is.

When a galaxy falls into a cluster, it often has gas stripped away by «headwinds» created as the galaxy moves through the cluster's own gas.

The action of electric currents driven by moving gas later amplified the field inside galaxies by a «dynamo effect».

The dwarf galaxy also is of interest because it provides clues to how the early simple universe became re-ionized by early star formation, moving it from the so - called cosmic Dark Ages of neutral gases to the development of the complexly structured universe now in existence, where the gas between galaxies is ionized.

The galaxies are moving toward each other, and being accelerated by their mutual gravity (Image: NASA / STScI)

«In 1933 the late Fritz Zwicky pointed out that the galaxies of the Coma cluster are moving too fast: there is not enough visible mass in the galaxies to bind the cluster together by gravity.

Scientists can figure out how much mass there is in a galaxy by tracking how fast things inside move, Pieter van Dokkum, one the authors of a new research paper published in Nature, told Newsweek.

In 1986 a group of astronomers observing the motions of the Milky Way and neighbouring galaxies noted that the galaxies were moving toward the Hydra - Centaurus superclusters in the southern sky with velocities significantly different from those predicted by the expansion of the universe in accordance with the Hubble law (see Hubble's constant).

Since 1976, William Tifft, a University of Arizona astronomer, has found that distant stars and galaxies have redshifts that typically differ from each other by only a few fixed amounts.21 This is very strange if stars are actually moving away from us.

In fact, the ring - like shape is the result of the gravitational disruption caused by a small intruder galaxy passing through a large one, compressing the interstellar gas and dust, and causing a wave of star formation wave to move out from the impact point like a ripple across the surface of a pond.

Taking into account that the relatively nearby (in the sky) galaxy M98 is approaching us at 125 km / sec, and thus moving at about the same peculiar velocity but, by chance, toward us, one may speculate that these two galaxies might have been involved in an encounter, but this is currently not much more than wild speculation.

However, other measurements taken by a team of researchers from the University of Strasbourg in France appear to show that stars just outside of Triangulum II are moving faster than the ones close to the galactic center — which were used by Kirby to determine the galaxy's mass.

The beams that would have to be regularly targeted at the craft could, the theory goes, move far beyond and reach Earth intermittently as FRBs, disrupted by the movement of distant galaxies and planets.

By measuring the rapid orbits of the stars near the center of our galaxy, Dr. Ghez and her colleagues have moved the case for a supermassive black hole at the heart of the Milky Way from a possibility to a certainty.

MAUNAKEA, Hawaii — A team of astronomers at the Friedrich Alexander University led by Péter Németh has discovered a binary star moving nearly at the escape velocity of our galaxy.

SDSS studies have probed the dark matter environments of quasars through clustering measurements, revealed populations of quasars whose central engines are hidden by obscuring dust, captured changes in quasar spectra that show clouds moving in the gravitational grip of the central black hole, and allowed a comprehensive census of the much fainter accreting black holes (active galactic nuclei, or AGN) in present - day galaxies.

Written by Dan Simmons, this tale imagines a future in which St Peter's basilica is moved from the Vatican to another planet, and the Catholic Church becomes a universal religion across the galaxy, thanks to an alien life form that causes a form of reincarnation.

Students can move through time meeting extinct dinosaurs, tour the solar system and the Milky Way galaxy, explore DNA that can't be seen by the human eye, read interviews with museum scientists and student scientists like themselves, play games, collect Ology cards and create projects with them, learn about expeditions, take quizzes, and more.

Lamborghini moved $ 30 million worth of cars by restyling twenty Murciélagos — I imagine they'd have made hay with the fastest car in the galaxy.

Re 51 Tom P — watched the video; and I agree that the sun does wobble around the center of mass of the solar system; the center of mass itself is not tending to wobble around the sun because conservation of momentum applies to the solar system as a whole (except of course for the forces applied to it by nearby stars, the rest of the galaxy, etc, but those are not varying so fast and so the center of mass should generally be moving along rather smoothly on the same timescale as planetary motions).
