Antlia ( //; from Ancient Greek ἀντλία) is a constellation in the southern sky. Its name means "pump" and it specifically represents an air pump. The constellation was created in the 18th century from an undesignated region of sky, so the stars comprising Antlia are faint. Antlia is bordered by Hydra the sea snake, Pyxis the compass, Vela the sails, and Centaurus the centaur. This group of constellations is prominent in the southern sky in late winter and spring. NGC 2997, a spiral galaxy, and the Antlia Dwarf Galaxy lie within Antlia's borders.
Antlia was created in 1756 by the French astronomer Abbé Nicolas Louis de Lacaille, who created fourteen constellations for the southern sky to fill some faint regions. Though Antlia was technically visible to ancient Greek astronomers, its stars were too faint to have been included in any constellations. Because of this, its main stars have no particular pattern and it is devoid of bright deep-sky objects. It was originally named Antlia pneumatica ("Machine Pneumatique" in French) to commemorate the air pump invented by the French physicist Denis Papin. Lacaille and Johann Bode each depicted Antlia differently, as either the single-cylinder vacuum pump used in Papin's initial experiments, or the more advanced double-cylinder version. The International Astronomical Union subsequently adopted it as one of the 88 modern constellations. There is no mythology attached to Antlia as Lacaille discontinued the tradition of giving names from mythology to constellations and instead chose names mostly from scientific instruments.
Because it occupies a part of the celestial sphere that faces away from the Milky Way, Antlia contains very few deep-sky objects. It contains no globular clusters, no planetary nebulae, and no open clusters. However, it does contain several galaxies.
NGC 2997 is a loose face-on spiral galaxy of type Sc. It is the brightest galaxy in Antlia at an integrated magnitude of 10.6. Though nondescript in most amateur telescopes, it presents bright clusters of young stars and many dark dust lanes in photographs.
Chinese astronomers were able to view what is modern Antlia from their latitudes, and incorporated its stars into two different constellations. Several stars in the southern part of Antlia were a portion of "Dong'ou", which represented an area in southern China. Furthermore, epsilon Antliae, eta Antliae, and theta Antliae were incorporated into the celestial temple, which also contained stars from modern Pyxis.

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
