Messier 80

Messier 80 is a globular cluster in the constellation Scorpius. It was discovered by Charles Messier in 1781; the star cluster is located midway between α Scorpii and β Scorpii in a field in the Milky Way, rich in nebulae. It can be viewed with modest amateur telescopes as a mottled ball of light. With an apparent diameter of about 10' and at an estimated distance of 32,600 light-years, M80's spatial diameter is about 95 light-years, it contains several hundred thousand stars, is among the more densely populated globular clusters in the Milky Way. It contains a large number of blue stragglers, stars that appear to be much younger than the cluster itself, it is thought these stars have lost part of their outer layers due to close encounters with other cluster members or the result of collisions between stars in the dense cluster. Images from the Hubble Space Telescope have shown districts of high blue straggler densities, suggesting that the center of the cluster is to have a high capture and collision rate.

On May 21, 1860, a nova was discovered in M80 that attained a magnitude of +7.0. The nova, variable star designation T Scorpii, reached an absolute magnitude of −8.5 outshining the entire cluster.

Mari-Cha IV

Mari-Cha IV is a sailing superyacht built as a two-masted schooner. The boat was ordered by Robert Miller with the particular goal of winning sailing records; the designers were Clay Oliver. The yacht has waterline length of 40.2 m, a width of 9.6 m, a displacement of 50 t. It was equipped with a canting keel with a 10 t keel bulb, able to exert a much larger righting moment a conventional keel. On October 9, 2003, Mari-Cha IV improved the previous record for fastest west-east transatlantic passage by a sailing monohull by more than two days, with total time of 6 days, 17h, 15m and 39s. During the run, she won the record for longest 24h distance sailed, with 525.5 nautical miles. This record was only broken 13 years in 2016, by Comanche. Mari-Cha IV gained particular distinction in 2005, when she broke the 100-year-old record for fastest monohull Atlantic crossing under regatta conditions established by Atlantic under Charlie Barr during the 1905 Kaiser's Cup. During the 2005 Rolex Transatlantic Challenge she beat out Maximus for line honours and set the new record of 9 days, 15 hours, 55 minutes and 23 seconds.

In July 2004, the yacht won the record for the fastest passage from the US west coast to Hawaii. In year 2015 the yacht was converted to a fast luxury cruiser; the canting keel was replaced by a simpler retracting keel, the ship was given a new cabin and interior

Kingdom Hearts: Chain of Memories

Kingdom Hearts: Chain of Memories is an action role-playing video game co-developed by Square Enix and Jupiter, published by Square Enix in 2004 for the Game Boy Advance. The game serves as an intermediary between the two larger-scale Playstation 2 games in the Kingdom Hearts series, it was one of the first GBA games to incorporate full motion video. Kingdom Hearts: Chain of Memories is the second game in the Kingdom Hearts series, it is a direct sequel to Kingdom Hearts, its ending is set about a year before Kingdom Hearts II. The game follows Sora and friends, as they explore the mysterious Castle Oblivion while battling the sinister Organization XIII, a group of antagonists new to the series; the game introduces new characters and plotlines that further expand the Kingdom Hearts universe and set up the premise for Kingdom Hearts II. The game features a new card-based battle system, in a departure from its predecessor's real time combat system. Though not as successful as the other Kingdom Hearts games, it received positive reviews and sold well, with particular praise for its story, FMVs.

When it debuted in Japan, it sold 104,000 units in 48 hours. The game was remade for the PlayStation 2 as Kingdom Hearts Re:Chain of Memories, released in Japan as a second disc packaged with Kingdom Hearts II Final Mix in March 2007; the remake was released in North America on December 2, 2008 and was remastered in HD and included in the Kingdom Hearts HD 1.5 ReMix collection released in 2013 for the PS3 and PS4. Kingdom Hearts: Chain of Memories is a combination between a role-playing video game and collectible card game; the main role-playing aspect is an experience point system, used to increase the character's maximum health or Card Points, or to learn a new skill. The cards are utilized in the progression of the story as well as in combat; the game features a field battle screen. The field map is an isometric area. Enemies inhabit the field map and track the player to engage in combat, which can be initiated through contact between the player and an enemy. Once combat has been engaged, the game switches to the battle screen which utilizes a card-based battle system.

A unique aspect to this game is "room synthesis": to advance through the game, the player must utilize Map cards obtained after winning battles to synthesize rooms. The properties of each room―including quality of items and strength of enemies―are determined by the Map cards the player chooses; each card has a specific effect: red cards affect the number and type of enemies. The game features three modes of gameplay; the first two are story modes that feature either Sora or Riku, the third is a two player battle mode. Only Sora's story mode is available. Reverse/Rebirth allows the player to play a second story mode featuring Riku and a link mode where players can battle each other via a Game Link Cable. Combat uses a card-based battle system executed in real time; the player can jump and maneuver around the battle screen as they would on the field map, but all physical attacks, magic and summonings are activated by playing cards. Cards are ranked from zero to nine, are used for making attack combos or breaking enemy cards.

With the exception of zero-ranked cards which are more expensive in terms of Card Points compared to other cards of the same type and have other ranks, more CP are required to place higher-ranked cards in the player's deck. Card Points -- increased through level up -- limit the number of cards. Cards with rank "zero" can break any opposing card or combo if played after the opposing card or combo, but they can be broken by any card or combo as well if it is played after the zero card is played. Breaking an opposing card will cancel that attack and stun the loser of a card break for a short time. Special enemy cards may be obtained by defeating enemies and bosses, are used to give the player a temporary ability, ranging from enhanced offensive and defensive capabilities to modifying the attributes of certain cards. Combining cards in sets of three will create combo attacks that are more difficult to break because the rank of the combo will be the sum of the ranks of the three cards in the combo.

Certain card combinations will create a "sleight", a special combination that will create a powerful physical attack, magical spell, or summon attack. When the player runs out of cards, the deck must be reloaded. Additionally, using a card combination will cause the first card in the combo to become unusable until the end of combat. Sora's and Riku's stories differ gameplay-wise in several ways. In Sora's story, Sora obtains cards through Moogle Shops. In some cases, Sora must earn the specific card first through a plot event before it becomes available. Sora can store three different decks in the pause menu. Unlike Sora, Riku has a closed deck; the cards in his deck change depending on the world. Riku is limited to physical attacks, enemy cards and Mickey Mouse ally cards, he can activate "dark mode" and unlock his sleight attacks if he accumulates enough "dark points". Dark points are earned by breaking enemy cards and combos, the difference between Riku's card or combo and the enemy's card or combo is how many dark points he will accumulate for that card break.

Kingdom Hearts: Chain of Memories is set after the events of the first game. It is set in a mysterious castle kept by Lord Marluxia. Sora and his teammates are told
