Step Outside And See Mercury At Sunset
2013-02-09 10:02:39

NASA Science NASA has recently discovered a very strange planet. Its days are twice as long as its years. It has a tail like a comet. It is hot enough to melt lead, yet capped by deposits of ice. And to top it all off ... it appears to be pink. The planet is Mercury. Of course, astronomers have known about Mercury for thousands of years, but since NASA's MESSENGER probe went into orbit around Mercury in 2011, researchers feel like they've been discovering the innermost planet all...

April Flowers for redOrbit.com - Your Universe Online To study charge exchange, a poorly understood phenomenon that occurs when the solar wind collides with Earth's exosphere and neutral gas in interplanetary space, three NASA scientists teamed up to develop and demonstrate NASA's first wide-field-of-view soft X-ray camera. It is rare to have researchers from such diverse disciplines as heliophysics, astrophysics and planetary science teaming up, but that's exactly what happened at...

Comet ISON To Put On Spectacular Show On Thanksgiving
2013-02-06 13:08:48

Alan McStravick for redOrbit.com - Your Universe Online Kislovodsk, literally translated, means “sour water.” It was in this town, named for the sour water in the springs that surround it, that Russian astronomers Vitali Nevksi and Artyom Novichonok made a very sweet discovery in September of last year. Officially, the comet they discovered was named C/2012 S1, but since the two astronomers were using the International Scientific Optical Network´s (ISON) 15.7-inch...

Scientist Calls Clovis Comet Theory Bogus
2013-01-30 20:42:49

Lee Rannals for redOrbit.com — Your Universe Online Researchers are contradicting one hypothesis that comet explosions may have ended the 9,000-year-old Clovis culture. The Clovis comet hypothesis was first reported in 2007, claiming a comet initiated the Younger Dryas cold period nearly 13,000 years ago. This period, also known as the Big Freeze, was a brief period of cold climatic conditions and drought, causing the collapse of the North American ice sheets. According to the...

April Flowers for redOrbit.com - Your Universe Online The 2012 Edgar Wilson Award for the discovery of comets by amateurs was announced this week by the Minor Planet Center, located at the Smithsonian Astrophysical Observatory in Cambridge, Mass. The awards, created and funded by the will of the late business man Edgar Wilson of Lexington, Kentucky, have been given out for 14 consecutive years. Five recipients received plaques and cash awards this year: • Leonid Elenin of...

[ Watch the Video: ScienceCasts: Comet of the Century ] redOrbit Staff & Wire Reports - Your Universe Online A comet discovered by Russian astronomers last September could blossom into one of the stargazing highlights of the year, NASA officials announced on Friday. Comet ISON, which was found by Vitali Nevski and Artyom Novichonok of Roscosmos and named in honor of their International Scientific Optical Network night-sky survey program, is currently located near Jupiter. For...

WASHINGTON, Jan. 8, 2013 /PRNewswire-USNewswire/ -- Newly released NASA Hubble Space Telescope images of a vast debris disk encircling the nearby star Fomalhaut and a mysterious planet circling it may provide forensic evidence of a titanic planetary disruption in the system. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) Astronomers are surprised to find the debris belt is wider than previously known, spanning a section of space from 14 to nearly 20 billion miles from the...

Exocomets Are As Common As Exoplanets
2013-01-08 06:41:37

April Flowers for redOrbit.com - Your Universe Online A beautiful byproduct of our solar system's formation, comets trailing wispy tails across the night sky are icy leftovers from 4.6 billion years ago when the planets coalesced from rocky rubble. Six likely comets around distant stars were recently discovered by astronomers at the University of California, Berkeley and Clarion University suggesting that comets — dubbed "exocomets" — are just as common in other stellar...

New Year's Quadrantids Meteor Show To Peak This Week
2012-12-31 09:47:24

Brett Smith for redOrbit.com - Your Universe Online Sky watchers can expect the first big astronomical event of 2013 to happen just as the New Year begins to unfold. The annual Quadrantids meteor shower typically arrives in the beginning of January and is renowned for being more intense than the Perseids shower in August and the Geminids shower in December. Meteor visibility will peak around 2:30 a.m. EST on Jan. 3, with about 80 streaks per hour. A waning gibbous moon, about 50...

What Are The Geminids?

[ Watch the Video: What is a Meteor? ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Meteor showers are fascinating events - streaks of light across the darkness of night. While such displays struck fear into our ancestors, they provide wonderful entertainment today. These celestial shows are rather common, with some 50 showers in 2012 alone (though not all of them are observable everywhere on Earth). One of the most brilliant events is the Geminid meteor...

A Shubunkin is a type of single-tailed goldfish with calico coloration, a combination of orange, white, black, red, and blue markings, blue being the most desired. They are similar to the common goldfish and the comet goldfish. Also called speckled goldfish, harlequin goldfish, calico goldfish, and coronation fish, they were developed in Japan about a hundred years ago by crossing calico fantails with single-tailed goldfish to produce a hardy, able swimmer with bright colors. There are...

A Fantail goldfish is a standard "fancy" type of goldfish. It has a dual-lobed tail, unlike its cousin the common or comet. Its fins can be different sizes, ranging from 1-3 in or more in length. A typical fantail has paired fins, including anal fins, a single dorsal fin, and a round, pointed body shape. It can range in color, from bronze (known as chocolate), orange, red, calico, and mixes of the colors. It is the third hardiest of the fancy goldfish with Comet first and Shubunkin second,...

The Comet is a commonly kept form of goldfish, the only type to have originated in the United States. They first appeared in the ponds of the Fish Commission in Washington in the early 1880s. Hugo Mullertt was the first person to bring the Comet goldfish to the market in a large quantity. Characterized by a long, tall, flowing tailfin they can be differentiated from the common goldfish, although otherwise they are very similar. Both of these varieties are quite hardy and will do well in...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...

Solar System

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...
