Explanet Same Size As Earth
2013-10-30 16:15:10

Brett Smith for redOrbit.com - Your Universe Online In August, an international team of researchers announced the discovery of a planet outside our solar system - also referred to as an exoplanet - that orbits its star in just 8.5 hours and is roughly the same size as Earth. Now, the same research team members that found the planet, dubbed Kepler 78b, have made another startling discovery: the planet’s mass is roughly the same as our own. "This planet is a complete mystery," said...

Recalling The 2003 Nightmare Halloween Magnetic Storm
2013-10-30 08:32:39

[ Watch the Video: Is There Space Weather In Store For Trick-Or-Treaters? ] Lawrence LeBlond for redOrbit.com - Your Universe Online As Halloween approaches, most people are thinking about costume parties, tricks and treats, haunted hayrides and perhaps a rogue werewolf running amok. But for scientists, this October 31 may provide a scare much different from what most kids get when they go Trick-or-Treating this All Hallow's Eve. The NOAA/NWS Space Weather Prediction Center on...

Sun Continues To Produce Solar Flares
2013-10-28 11:08:45

NASA After emitting its first significant solar flares since June 2013 earlier in the week, the sun continued to produce mid-level and significant solar flares on Oct. 27 and Oct. 28, 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 GPS and communications signals travel. To see how...

Lessons From Hurricane Sandy: Put Parks, Not Houses, On the Beach
2013-10-28 09:25:19

The Geological Society of America Just days before Hurricane Sandy hit the New York and New Jersey coastline on 29 October 2012, scientists from the City University of New York's (CUNY) College of Staten Island had produced the most detailed model to date of the region's potential for damage from big storms. So naturally, the morning after the floods receded from Staten Island, CUNY geology professor Alan I. Benimoff was out mapping the high-water marks in the flooded neighborhoods. There...

Exoplanets With Too Much Carbon Are Most Likely Waterless
2013-10-26 04:14:31

redOrbit Staff & Wire Reports - Your Universe Online Diamond planets and other worlds that are rich in carbon might be waterless, NASA researchers explained earlier this month at the 45th meeting of the American Astronomical Society Division of Planetary Sciences in Denver. Torrence Johnson, a Senior Research Scientist at the Jet Propulsion Laboratory (JPL) in Pasadena, California, and his colleagues explain that since our sun is a carbon-poor star, the Earth is a planet that is...

Astronomers Discover Seventh Planet Orbiting Nearby Star System
2013-10-25 15:26:17

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered a seventh planet orbiting a dwarf star, known as KIC 11442793, making it the first Kepler planetary system with this many alien worlds. The star is about 2,500 light years from Earth and its planetary system could be a record holder. All seven planets in the system orbit much closer to their host star, meaning the system is very crowded when compared to even our own Solar System. Scientists say that the...

More Than 1,000 Exoplanets Have Been Discovered Since 1992
2013-10-25 14:17:10

Lee Rannals for redOrbit.com - Your Universe Online The search for extra-terrestrial planets has been ongoing for at least the past 21 years. Since the early days of exoplanet hunting, the number of such planets identified by scientists has pushed beyond a thousand, thanks largely to the advent of high-tech space observatories, such as the Kepler Space Telescope. Exoplanets, or alien planets, are those planets that exist outside of our Solar System. So far, scientists have discovered...

Earthen Crust Oxygen Got Its Start During Creation Of Solar System
2013-10-25 07:03:56

April Flowers for redOrbit.com - Your Universe Online A long standing mystery in the formation of the Solar System has been solved by cosmochemists from the University of California, San Diego (UCSD). In the oldest, most pristine rocks, oxygen, the most abundant element in the Earth's crust, follows a strange, anomalous pattern that must result from a different chemical process than the well-understood reactions that form minerals containing oxygen on Earth. "Whatever the source of...

NASA's SDO Captures Image Of Mid-level Solar Flare
2013-10-24 12:46:59

NASA The sun emitted a mid-level solar flare that peaked at 8:30 pm EDT on Oct. 23, 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 GPS and communications signals travel. Such radiation can disrupt radio signals for as long as the flare is ongoing, anywhere from minutes to hours. To see...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

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...
