Voyager 1 Still Within The Confines Of Solar System
2013-06-27 15:36:08

Lee Rannals for redOrbit.com - Your Universe Online Scientists are split on exactly where NASA's Voyager 1 spacecraft is sitting within the Solar System, but new research from the space agency suggests it is on the last frontier out. A team of scientists wrote in Geophysical Research Letters in March that the spacecraft had already left our Solar System. However, the latest intel from NASA shows that the spacecraft is still sitting just within the edge of our "Solar Bubble."...

[ Watch the video IRIS Science Overview ] Lee Rannals for redOrbit.com - Your Universe Online Update (June 25, 2013 3:10 p.m.) NASA announced on Tuesday that its planned launch for its Interface Region Imaging Spectrograph (IRIS) mission has been moved due to the "recent central California power outage." The launch window has moved from Wednesday, June 26 to Thursday, June 27. Stay tuned for further updates. Main Story (June 24, 2013 12:43 p.m.) NASA's Interface...

Suck It Up! Sun Provides Insight Into How Young Stars Grow
2013-06-21 04:26:50

April Flowers for redOrbit.com - Your Universe Online Our Sun erupted on June 7, 2011, sending tons of hot plasma blasting into space. Some of the plasma fell back to the surface of the Sun, sparking bright flashes of ultraviolet light. A new study from the Harvard-Smithsonian Center for Astrophysics (CfA) examines the dramatic event to provide new insights into how young stars grow by consuming nearby gas. NASA's Solar Dynamics Observatory captured the eruption and subsequent...

Pulsating White Dwarf Discovered By UT Astronomers
2013-06-20 12:47:40

Lee Rannals for redOrbit.com - Your Universe Online A group of astronomers have discovered pulsations from the crystallized remnant of a burnt-out star. The researchers recently reported in The Astrophysical Journal Letters that they were able to use the 2.1-meter Otto Struve Telescope at the University of Texas McDonald Observatory to take a look at the white dwarf GD 518 and discover the pulsations. This finding will allow scientists to see below the star's atmosphere and into its...

Sunrise 2 Launched Successfully
2013-06-12 10:28:55

Max Planck Institute for Solar System Research The balloon-borne solar observatory Sunrise has lifted off - and will now begin its unique journey to the active Sun. The balloon-borne solar observatory Sunrise has lifted off successfully from Esrange Space Center in the north of Sweden. Today at 7.37 a.m. CEST the launching vehicle released the gondola and the huge balloon lifted Sunrise into the sky. Ever since the last ground-based tests had been completed during the past week, the...

M5.9 Solar Flare Emitted By The Sun
2013-06-11 09:18:19

NASA The sun emitted a mid-level solar flare, peaking at 6:49 p.m. on June 7, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours. This flare is classified as an...

Badger Company, leading maker of natural and organic personal care products, introduces the SLOW Sun movement, designed to make time in the sun fun and simple again. The SLOW Sun movement — inspired by the SLOW Food movement, which was founded to encourage families to slow down and enjoy real meals together again encourages people to slow down and take a...

NASA AIM Satellite Spots First Noctilucent Clouds Of 2013
2013-06-09 09:08:50

redOrbit Staff & Wire Reports — Your Universe Online Noctilucent clouds (NLCs), tenuous cloud-like phenomena that form every summer in the skies above the North Pole, are forming earlier than usual, NASA officials confirmed on Friday. According to the US space agency, NLCs are formed when “ice crystals begin to cling to the smoky remains of meteors, forming electric-blue clouds with tendrils that ripple hypnotically against the sunset sky.” These clouds, which...

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...

Solar Physics

Solar Physics is a journal for solar and solar-stellar research and the study of solar terrestrial physics. Founded in 1967 by solar physicist Cornelis de Jager and publisher D. Reidel, the journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution, to outer corona and solar wind in interplanetary space. Solar Physics has four more than forty years been the principal journal for publications of fundamental research on the Sun. It is...

The spectroheliograph captures a photographic image of the Sun at a single wavelength of light. The wavelength chosen usually coincides with a spectral wavelength of one of the chemical elements present in the Sun. George Ellery Hale and Henri-Alexadre Deslandres developed I independently in 1890 and was further refined in 1932 by Robert R. McMath to take motion pictures. It operates by using a prism together with a narrow slit that passes a single wavelength. The light focuses on a...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
