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.

"Naughty" is the debut single by Australian recording artist Elen Levon, featuring Israel Cruz. It was released digitally on 30 September 2011. The song peaked at number 60 on the ARIA Singles Chart, and number 17 on the ARIA Dance Chart.

It debuted and peaked at number 60 on the ARIA Singles Chart on 10 October 2011. That same week, "Naughty" peaked at number 17 on the ARIA Dance Chart.
Levon performed the song at Erin McNaught's Naughty for Zu shoe collection launch party in Sydney on 5 October 2011. Throughout January 2012, "Naughty" was used in television commercials for the American television series Gossip Girl on Fox8. Levon later performed the song during her Naughty Nights tour with Marvin Priest in February 2012.
The accompanying music video for "Naughty" premiered online on 28 August 2011. The video features Levon and her backup dancers performing choreographed routines in front of a backdrop of light bulbs. She is also seen singing the song while lying on the floor with her dancers surrounding her, as well as in a chair in front of speakers.
