Hypothesis
Since the discovery of Pluto, many have speculated that it might not be alone. The first astronomer to suggest the existence of a trans-Neptunian population was Frederick C.
Hypothesis. An untested statement about nature; a scientific conjecture, or educated guess. Formally, a hypothesis is made prior to doing experiments designed to test it. Compare: law and theory.

Hypothesis
A scientific proposition that purports to explain a given set of phenomena; less comprehensive and less well established than a theory.

If the universe is expanding, then it must have been much smaller and therefore hotter and denser in the past.
GAIA HYPOTHESIS - Idea that the Earth as a whole should be regarded as a living organism and that biological processes stabilize the environment. This hypothesis was first proposed by British biologist James Lovelock in 1969.

Nebular Hypothesis
Hypothesis, maintained in the nineteenth and early twentieth century, that the spiral nebulae are not galaxies but are instead whirlpools of gas from which new systems of stars and planets are condensing.

hypothesis - A tentative theory or supposition, advanced to explain certain or phenomena, which is subject to further tests and verification.
A hypothesis is proposed - this is the "new" idea that you have to explain something that may or may not have been previously known or observed
The hypothesis should have specific expectations - there should be predictable, reproduceable results.
The hypothesis is that green roofs could cool urban heat islands. These are places where the temperature is often warmer than surrounding areas. Most major cities are urban heat islands because they have a lot of asphalt and cement.
One hypothesis is heat from the impact that carved Herschel crater could have melted surface ice that spread across a wide area of Mimas.
"The hypothesis is that this is a volcanic rock, but we'll test that hypothesis," he said.
"The hypothesis that dust storms can be expected on Mars near the time of perihelion and southern summer solstice (Antoniadi, 1930; Capen, 1971) has become so well accepted that the prediction of such an event for 1973 (Capenand ...
Zwicky hypothesised as early as early as 1933 that a star could be composed entirely of neutrons. A star so massive that its gravity overcomes the electron degeneracy pressure , forcing the electrons into the protons, converting them into neutrons.

PLANETESIMAL HYPOTHESIS
The planetesimal hypothesis is a theory about the formation fo the Solar System. It was proposed by Thomas Chrowder Chamberlain (Sept. 25, 1843 - Nov. 15, 1928), an American geologist and teacher.

The fundamental hypothesis of the science assumes a system of bodies in motion, of which the sun and planets may be taken as examples, and of which each separate body is attracted toward all the others according to the law of Newton.

momentum-transport hypothesis The hypothesis that momentum is conserved in turbulent eddy transfer.
The aether hypothesis, however, led two U.S. scientists, Albert Abraham Michelson and Edward Williams Morley, to conceive of an experiment (1887) intended to measure the motion of the aether on the surface of the Earth in their laboratory.
Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received.
In 1966, however, Robert Leighton and Bruce Murray of the United States published the results of a numerical model of the thermal environment on Mars that raised considerable doubt about the water ice hypothesis.
According to one recent hypothesis, unusually intense stellar flares from a sun-like ("Sol-type") star could be caused by the interaction of the magnetic field of a giant planet in tight orbit with that star's own magnetic field (Rubenstein and ...
One hypothesis is that the center of our Galaxy contains a black hole. This wouldn't be your garden variety black hole but a supermassive black hole with a mass perhaps a million times that of the sun.
(A good example of such a theory is the collision hypothesis, which imagines that the planets were torn from the Sun by a close encounter with a passing star.
Probably the most amazing theoretical trans-Neptunian object is the hypothesised Nemesis. This is a predicted companion star to the Sun, with an elliptical orbit between 20 000 and 90 000 AU from the Sun and a period of 30 million years.
This sequence provides an excellent illustration of the hypothesis first propounded by Charles Darwin to explain the origin of coral reefs in deep oceans.
* In 1905, Albert Einstein (1879:1955) published his "Special Theory of Relativity", a simple and elegant hypothesis that made a number of remarkable assertions: nothing could exceed the speed of light; clocks in a moving object slow down; ...

Astronomers have been recording observations and hypothesis for over 2,000 years. I don't think that we could squeeze them all in one on page and do justice to their individual contributions.
It has been hypothesised to account for the observational properties of distant type Ia supernovae, which show the universe going through an accelerated period of expansion.
Sometimes, an idea that is really a hypothesis is incorrectly called a theory. A true scientific theory is a hypothesis that makes predictions. Those predictions have been tested and have proven to be accurate.
Thomas Chrowder Chamberlain (Sept. 25, 1843 - Nov. 15, 1928) was an American geologist and teacher who proposed the planetesimal hypothesis of the formation of the Solar System.
of Jupiter were the first objects found to be revolving around an object other than the Earth; this was part of a blow, when put together with the findings of Kepler and Issac Newton, from which the geocentric (earth centered) universe hypothesis ...

Most people use the working hypothesis that a black hole is involved, largely influenced by the discussion of Rees (1978 Physica Scripta 17, 193, redrawn here following the version in Begelman, Blandford, and Rees in Rev. Mod. Phys. 56, 255) that ...
During the past decade, the hypothesis that spiral galaxies can collide and merge to form elliptical galaxies has become increasingly popular.
The star is a notable binary, but with a companion which is very dim and very close. The companion is a white dwarf, and its presence wasn't really discovered at first; it was just a hypothesis.
It is just part of the accepted picture. At the beginning of the twentieth century, however, this was not the case. The idea of external galaxies was only a hypothesis, and a not widely held one at that.
One of the most popular hypothesis is the supermassive black hole theory. When materials surrounding the black hole fall into it, large amount of energy is released. Galaxy collision may create the supermassive black hole at the center.
