Helianthus or sunflowers (from the Greek: ήλιος, Hēlios, "sun" and ανθός, anthos, "flower") L. /ˌhiːliˈænθəs/ is a genus of plants comprising about 70 species in the family Asteraceae. Except for three species in South America, all Helianthus species are native to North America. The common name, "sunflower," also applies to the popular annual species Helianthus annuus, the common sunflower. This and other species, notably Jerusalem artichoke (H. tuberosus), are cultivated in temperate regions as food crops and ornamental plants.
The genus is one of many in the Asteraceae that are known as sunflowers. It is distinguished technically by the fact that the ray flowers, when present, are sterile, and by the presence on the disk flowers of a pappus that is of two awn-like scales that are caducous (that is, easily detached and falling at maturity). Some species also have additional shorter scales in the pappus, and there is one species that lacks a pappus entirely. Another technical feature that distinguishes the genus more reliably, but requires a microscope to see, is the presence of a prominent, multicellular appendage at the apex of the style. Sunflowers are especially well known for their symmetry based on Fibonacci numbers and the Golden angle.
Sunflower is the fifth studio album by the American pop band Never Shout Never. It was released on July 2, 2013 by Loveway Records. The album features the band recording as a whole for the third time; the first being in Time Travel, the second on Indigo.

Fantasia is a 1940 American animated film produced by Walt Disney and released by Walt Disney Productions. With story direction by Joe Grant and Dick Huemer, and production supervision by Ben Sharpsteen, it is the third feature in the Disney animated features canon. The film consists of eight animated segments set to pieces of classical music conducted by Leopold Stokowski, seven of which are performed by the Philadelphia Orchestra. Music critic and composer Deems Taylor acts as the film's Master of Ceremonies, providing a live-action introduction to each animated segment.
Disney settled on the film's concept as work neared completion on The Sorcerer's Apprentice, an elaborate Silly Symphonies short designed as a comeback role for Mickey Mouse, who had declined in popularity. As production costs grew higher than what it could earn, he decided to include the short in a feature-length film with other segments set to classical pieces. The soundtrack was recorded using multiple audio channels and reproduced with Fantasound, a pioneering sound reproduction system that made Fantasia the first commercial film shown in stereophonic sound.
Cassini is a surname. Notable people with the surname include:
Cassini–Huygens is an unmanned spacecraft sent to the planet Saturn. It is a flagship-class NASA–ESA–ASI robotic spacecraft. Cassini is the fourth space probe to visit Saturn and the first to enter orbit, and its mission is ongoing as of 2016. It has studied the planet and its many natural satellites since arriving there in 2004.
Development started in the 1980s. Its design includes a Saturn orbiter, and a lander for the moon Titan. The lander, called Huygens, landed on Titan in 2005. The two-part spacecraft is named after astronomers Giovanni Cassini and Christiaan Huygens.
The spacecraft launched on October 15, 1997 aboard a Titan IVB/Centaur and entered orbit around Saturn on July 1, 2004, after an interplanetary voyage that included flybys of Earth, Venus, and Jupiter. On December 25, 2004, Huygens separated from the orbiter and reached Saturn's moon Titan on January 14, 2005. It entered Titan's atmosphere and descended to the surface. It successfully returned data to Earth, using the orbiter as a relay. This was the first landing ever accomplished in the outer Solar System.
Cassini is a crater on Mars named in honour of the Italian astronomer Giovanni Cassini.
The crater measures approximately 415 kilometers in diameter and can be found at 327.9°W and 23.8°N. It is in the Arabia quadrangle of Mars. Pictures of small craters on the floor of Cassini reveal multiple layers. Some of these layers can be easily seen in the pictures below. Many places on Mars show rocks arranged in layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. A detailed discussion of layering with many Martian examples can be found in Sedimentary Geology of Mars.
Recent research leads scientists to believe that some of the craters in Arabia may have held huge lakes. Cassini Crater probably once was full of water since its rim seems to have been breached by the waters. Both inflow and outflow channels have been observed on its rim. The lake would have contained more water than Earth's Lake Baikal, our largest freshwater lake by volume.
