Wikipedia
Aster (genus)

Aster is a genus of flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 180 species, all but one of which are restricted to Eurasia; many species formerly in Aster are now in other genera of the tribe Astereae.

Aster (missile family)

The Aster missile series, primarily comprising the Aster 15 and Aster 30 are a family of vertically launched surface-to-air missiles. The name "Aster" originates from the mythical Greek archer named Asterion (in Greek mythology), Asterion likewise receiving his name from the ancient Greek word aster , meaning "star". Aster is manufactured by Eurosam, a European consortium consisting of MBDA France, MBDA Italy (combined 66%) and the Thales Group (33%). The missile is designed to intercept and destroy a wide range of air threats, such as supersonic anti-ship cruise missiles at very low altitude ( Sea-skimming) and fast flying, high performance aircraft or missiles.

Aster is primarily operated by France, Italy, and the United Kingdom and is an integrated component of the PAAMS air-defence missile system, known in the Royal Navy as Sea Viper. As the principal weapon of the PAAMS system, Aster equips the Type 45 destroyers and the Horizon class frigates. Aster also equips the French and Italian FREMM multipurpose frigates, though they will not be operating as part of a PAAMS air-defence suite.

Although the Aster 30 is anti-ballistic missile capable, an Aster Block 2 BMD (Ballistic Missile Defence) variant of the Aster 30 missile, with Hit-To-Kill and exo-atmospheric capability, is currently being developed.

Aster (cell biology)

An aster is a cellular structure shaped like a star, formed around each centrosome during mitosis in an animal cell. Astral rays, composed of microtubules, radiate from the centrosphere and look like a cloud. It is one of the variants of microtubules like kinetochore- and interpolar microtubules.

During mitosis, there are four stages of cell division: Prophase, Metaphase, Anaphase, and Telophase. During prophase, two aster-covered centrosomes migrate to opposite sides of the nucleus in preparation of mitotic spindle formation. During metaphase, the kinetochore microtubules connect to the centromere. Afterwards, during anaphase, the kinetochore microtubules pull the chromatids apart into its individual chromosomes and pull them towards the centrosomes, located at opposite ends of the cell. This allows the cell to divide properly with each daughter cell containing full replicas of chromosomes. In some cells, the positions of the asters determine the site of cell divisions.

Aster (typeface)

The Aster typeface, which originated in Italy, was designed in 1958 by Francesco Simoncini for Simoncini to be used in newspapers and books. This typeface is fairly wide with detailed, delicate serifs; it also has short ascenders and descenders for economy of space. The New Aster font family offers a few distinguishing marks, like the spurs of capitals A, N, V and W.
