Comet Pan-STARSS Survives Solar Encounter, Emerges Brighter Than Ever
2013-03-17 09:17:25

redOrbit staff & Wire Reports — Your Universe Online A comet making its first visit to the inner solar system has survived a journey that brought it close to the sun, and has emerged as one of the brightest comets in years, NASA astronomers confirmed on Friday. Comet Pan-STARRS, which according to the Daily Mail has been visible for several weeks in the Southern Hemisphere, could be viewed for the first time by stargazers in the northern parts of the world last week after...

Comet PANSTARRS Arrives In March
2013-03-06 09:00:24

Lee Rannals for redOrbit.com - Your Universe Online This March sky gazers will be treated to another special celestial event as comet Pan-STARRS C/2011 L4 becomes visible to the naked eye in the Northern Hemisphere. According to astronomers from the University of Hawaii, the comet should become visible from about March 7 just above the horizon. In order to see the comet, you will need to find dark skies away from the lights of the city. Scientists say that this comet will have a...

New Comet Discovery May Be Brightest Visitor In Past Hundred Years

Lawrence LeBlond for redOrbit.com - Your Universe Online Hale-Bopp, Haley´s, McNaught. These are just a few of the more well-known modern comets that have blazed across the night sky in our lifetime. Another comet that has been recently discovered could be added to that list next year when it makes a pass by the Sun in late 2013. The comet, named C/2012 S1 (ISON), is due to come within 1.1 million miles of the Sun on, or around, November 29, 2013. Vitali Nevski and Artyom...

Comet McNaught C/2009 R1 will become brighter than first thought and will be visible to the naked eye over the next few weeks. Australian astronomer Robert McNaught discovered the comet last September using the 0.5-meter Uppsala Schmidt telescope and a CCD camera.  Enough observations were made of the comet to allow Brian Marsden of the Smithsonian Astrophysical Observatory in Cambridge, Mass., to calculate its orbit. Comet McNaught is expected to pass closest to the sun at 37 million...

British scientists have identified a new candidate for the biggest comet measured to date. Dr Geraint Jones of UCL's Mullard Space Science Laboratory will be presenting the results at the RAS National Astronomy Meeting in Glasgow on Tuesday April 13th. Instead of using the length of the tail to measure the scale of the comet, the group has used data from the ESA/NASA Ulysses spacecraft to gauge the size of the region of space disturbed by the comet's presence. Analysis of magnetometer data...

As we kick off the year 2008, Comet Tuttle is putting on a nice show for backyard skywatchers. It had not been seen since 1994, but you'll have an excellent opportunity to pick it up with binoculars or small telescopes during the next two weeks. Tuttle can even be glimpsed by sharp-eyed observers under pristine skies without any optical aids, for it is one of the brightest of the short-period comets, those that orbit the sun often enough to be seen again and again from Earth and...

Recently, sky watchers in the Northern Hemisphere have been enjoying the sight of Comet McNaught in the twilight sky. Now, solar physicists using the ESA-NASA SOHO spacecraft are getting ready for their view. For four days in January, the comet will pass through SOHO's line of sight and could be the brightest comet SOHO has ever seen. As Comet McNaught heads towards its closest approach to the Sun on 12 January 2007, it will disappear from view for earthbound observers, becoming lost in the...

Halley's Comet -- Comet Halley, more generally known as Halley's Comet after Edmond Halley, is the best-known and the brightest of the "short-period" comets from the Kuiper belt that visit the inner solar system in years or decades-long orbits rather than the millennia of comets from the Oort Cloud. Early History Having perceived that the elements of the comet of 1682 were nearly the same as those of two comets which had appeared respectively in 1531 and 1607, Halley concluded that...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
