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.

Here's the real trip though: For every star in the Milky Way, there's a unique galaxy drifting through the universe, each with it's own billions of stars, and approximately one planet orbiting each of those stars.

Unfortunately, current estimates of the masses and orbits of Stars A and B — whose large margins of errors result in significant uncertainty — suggest that the orbit of a planet in the habitable zone of Star A could be disrupted.

«Often a non-Christian knows something about the earth, the heavens, and the other parts of the world, about the motions and orbits of the stars and even their sizes and distances,... and this knowledge he holds with certainty from reason and experience.

A new simulation of the orbits of stars after galaxy collisions concludes that invisible cocoons of matter do indeed exist around large nearby galaxies.

A simulation suggests that the gravity of hidden dark matter dictates the orbits of stars after galaxies collide, including stars flung far into space on distant, slow - moving orbits (right panel).

«If these galaxies grow through merging with minor companions, and these minor companions come in large numbers and from all sorts of different angles onto the galaxy, this would eventually randomize the orbits of stars in the galaxies.

To be able to generate a model for the orbits of stars in the bulge, Quillen needed to factor in different variables.

When two gas - rich giant spiral galaxies merge, the gravitational perturbation induced by the merging process disturbs the orbits of stars.

Swirls of infalling gas heat up and give off radiation to illuminate a black hole's vicinity, and the orbits of stars around a black hole allow astronomers to estimate its mass.

Ghez says that tracking the orbits of stars is the most direct way to study the black hole's properties.

A pair of new long - term studies tracking the orbits of stars at the center of the Milky Way Galaxy further refine the evidence that a supermassive black hole lurks there.

The ring might have come from gravitational interactions within the disk of the Milky Way itself, which spread out the orbits of stars over time.

Observations of the orbits of stars around galaxies suggest that all galaxies, including the Milky Way, are surrounded by a spherical cloud of dark matter (see diagram).

The orbits of the stars can be radically changed, though.

(See an animation of the orbits of Stars A and C and their potentially habitable zones, with a table of basic orbital and physical characteristics.)

(See an animation of the orbits of Stars Aa, Ab / D, B, C, and their potentially habitable zones, with a table of basic orbital and physical characteristics.)

Ghez used this cutting - edge system to track the orbits of stars near the supermassive black hole located at the center of the Milky Way.

Astronomers can determine the masses of stars in a binary system whose distance from the earth is known by calculating the orbits of the stars around each other.

But these effects will come in reach through precisely measuring the orbits of stars with GRAVITY, a second - generation instrument on the Very Large Telescope Interferometer (VLTI), which is an adaptive - optics assisted optical interferometer.

From the perspective of an observer on Earth, the orbit of Star A and the BC tight binary pair exhibit a very elongated and narrow ellipse whose separation has varied from 4.7» in 1880 to less than 0.4» in 1969 (Kaj Aage Gunnar Strand, 1937; A. Gennaro, 1940; L. Bennendijk, 1955; Worley and Heintz, 1983; and Wulff Dieter Heintz, 1963 to 1997; among others).

(See a larger, interactive animation of the orbits of Stars A and B, and a possibly disrupted habitable zone around Star A.) Useful star catalogue numbers and designations include: Alp or Alf CMa, 9 CMa, HR 2491, Gl 244 A, Hip 32349, HD 48915, BD - 16 1591, SAO 151881, FK5 257, LHS 219, and ADS 5423 A.

In fact, the apparent noncoplanarity of the orbits of star pairs Aab and Babc?

By measuring the orbits of stars at the center of our galaxy, she showed that a monstrous black hole resides at the center of our Milky Way galaxy, some 26,000 light - years away from Earth, with a mass 4 million times that of the sun.

The exact reason for this is uncertain, so the team is planning further observations to better understand the orbit of the star and its complicated family dynamics.

Furthermore, the noncoplanarity of the orbits of star pairs Aab and Babc?

(See an animation of the orbits of Stars A and B and their potentially habitable zones, with a table of basic orbital and physical characteristics.)

(See an animation of the orbits of star groups Aab and Babc?

Knud Jahnke and Rasmus Benestad says «The rotation is not rigid, but depends on the encircled mass inside the orbit of a star, including the Dark Matter, a yet unknown but solidly established source of gravitational attraction.»
