Einstein, Albert

 

Developed a model for gravity known as General Relativity, which is the basis for modern physical Cosmology.

[ACG52]

Transit- the passage of a celestial body across an observer's meridian,also the passage of a celestial body across the disk of a larger one.

[Janus]

Tombaugh, C. W. - American astronomer and discoverer of Pluto.

[ACG52]

White Dwarf- A very small, white star that is the remnant core of a star that has completed fusion in its core.

[Mordred]

Fraunhofer lines

 

Dark lines in the sun's spectrum which correspond to absorption wavelengths of component elements.

First letter

Starting letter was 'F',not 'I'

Cepheid- a pulsating variable star.

[MigL]

Dark matter

 

Postulated, non-luminous, mass distribution about a galaxy to account for its non-Newtonian spin.

[imatfaal]

Rubin, Vera. The first to formulate Dark Matter with strong evidence based on Galactic rotation curves

[zapatos]

American Astronomical Society - Formed in 1899 to enhance and share humanity's scientific understanding of the Universe.

[Janus]

YY Ori star - A type of irregularly variable star

[ACG52]

Radiant- a point in the sky from which meteors in a meteor shower seem to originate.

[Acme]

Telesto - A moon of Saturn named for a mythological sea goddess.

[ACG52]

Oort Cloud-

a shell of comets that is believed to exist at the outermost regions of our Solar System.

When given a name in the form of Tombough,C.W.do we key on the h in Tombough, or on the W?

[imatfaal]

Dwarf Planet. A small body orbiting the sun - it must be big enough to be spherical and be in hydrostatic equilibrium but may well not have cleared out local planetesimals; Pluto being the most famous example.

 

I think you follow on the last letter given - ie the W in Tombaugh C W

[MigL]

Terrestrial

 

Earth-like.

[ACG52]

Libration- an effect caused by the apparent wobble of the Moon as it orbits the Earth. The Moon always keeps the same side toward the Earth, but due to libration, 59% of the Moon's surface can be seen over a period of time.

[MigL]

Nucleosynthesis

 

The process of creation of elemental nuclei, such as creation of Hydrogen and Helium nuclei in Big Bang nucleosynthesis, and heavier nuclei in stellar and supernova nucleosynthesis.

[ACG52]

Solstice -

the time of the year when the Sun appears furthest north or south of the celestial equator. The solstices mark the beginning of the Summer and Winter seasons.

[Janus]

Elongation- The difference between the Moon's and The Sun's longitude.
