A pulsar (short for pulsating radio star) is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth (much the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that range roughly from milliseconds to seconds for an individual pulsar. Pulsars are believed to be one of the candidates of high and ultra-high energy astroparticles (see also Centrifugal mechanism of acceleration).
The precise periods of pulsars make them useful tools. Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. The first extrasolar planets were discovered around a pulsar, PSR B1257+12. Certain types of pulsars rival atomic clocks in their accuracy in keeping time.
Pulsar is a fictional character in the Marvel Universe, a member of the Shi'ar Imperial Guard.
The character first appeared as Impulse in X-Men #107 (October 1977-February 1978), and was created by Chris Claremont and Dave Cockrum.
The character subsequently appears in X-Men: Spotlight on Starjammers #2 (June 1990), Quasar #32 (March 1992), Inhumans Vol. 4 #4 (September 2000), JLA/Avengers #1 (September 2003), and Uncanny X-Men #477 (October 2006) and #480 (January 2007).
Impulse appeared as part of the "Imperial Guard" entry in the Official Handbook of the Marvel Universe Deluxe Edition #6.
Pulsar is a long-time member of the Shi'ar Imperial Guard, also known as Impulse. He is made of pure energy, and his form is only contained by his costume. He can release blasts of energy from his visor.
He was with the Imperial Guard the first time they fought the X-Men.
He was seemingly killed by Vulcan, who breached Impulse's suit. Pulsar later reappeared alive, battling alongside the rest of the Imperial Guard in an assault on the Kree, where Pulsar gravely wounded the Inhuman elite warrior, Gorgon.
Pulsar is a brand of watch and a division of Seiko Watch Corporation of America (SCA). While Pulsar was the world's first electronic digital watch, today Pulsar watches are usually analog. They generally use the same movements as the lower-end Seikos such as the 7T62 quartz chronograph movement.
The first Pulsar was a brand of The Hamilton Watch Company which announced that it was making the watch in early 1970. It was developed jointly by Hamilton and Electro/Data, Inc. In the spring of 1972, the first Pulsar watch was marketed by The Hamilton Watch Co. (the parent company, not the Hamilton Watch Division). With an 18-carat gold case, the world's first all-electronic digital watch was also the first to use a digital display — created with light-emitting diodes (LEDs). A button was pressed to display the time. The first Pulsar initially sold for $2100 ($12,300 in 2016 dollars).
The Potpourri segment in the October 1972 issue of Playboy mentions the first Pulsar - and carries a photo.

Encantadia is a Filipino fantasy television series (locally known as telefantasya) produced by GMA Network. It was dubbed as the grandest, most ambitious, and most expensive production for Philippine television during its time of release. The pilot episode was aired on May 2, 2005. Its last episode was aired on December 9 of the same year to give way to its second book, Etheria. This series aired its pilot episode on December 12, and its last episode on February 18, 2006. The third and latest installment of the Encantadia saga, entitled Encantadia: Pag-ibig Hanggang Wakas, aired its pilot on February 20, 2006 and the series ended on April 28, 2006.
The series garnered both popular and critical recognition at home and abroad, including winning the 2005 Teleserye (Television Series) of the Year at the Los Angeles-based Gawad Amerika Awards.
The entire Encantadia saga is currently aired on Fox Filipino.
Encantadia is a term coined from the Filipino words "enkanto", "enkanta", "enkantada", or "enkantado" (which was in turn derived from the Spanish term encant(ad){o/a}) which means enchanted beings endowed with supernatural powers.
Saint Alena (also written Alène or Alina) is a Christian saint who, if historical, was martyred around the year 640. She is sometimes referred to as Alena of Forest, or Alena of Brussels, having died in Forest, Belgium which is now one of the nineteen municipalities of Brussels.
The traditional account of Saint Alena's life, dating to the twelfth century, states that she was born in Dilbeek, just outside Brussels, Belgium, to pagan parents, the nobleman Levold and his wife, Hildegaart. Alena chose to be baptized without the knowledge of her parents. As a Christian, she had to attend Mass secretly.
When her father discovered that she was worshipping as a Christian, he came to the conclusion that Christians had bewitched her into conversion. He sent guards to bring her home; she resisted, and during the fighting she lost one arm. She subsequently died in prison due to her injuries.
Various (unspecified) miracles were claimed at the burial site of Alena's body, and one of Levold's subjects, Duke Omundus, had his sight restored by invoking Alena's prayers.
