Dawn spacecraft orbiting Ceres
2014-09-17 08:49:28

Elizabeth Landau, NASA's Jet Propulsion Laboratory The Dawn spacecraft has resumed normal ion thrusting after the thrusting unexpectedly stopped and the spacecraft entered safe mode on September 11. That anomaly occurred shortly before a planned communication with NASA's Deep Space Network that morning. The spacecraft was not performing any special activities at the time. Engineers immediately began working to restore the spacecraft to its normal operational state. The team determined...

exoplanet WASP-18b
2014-09-16 13:43:14

NASA A planet may be causing the star it orbits to act much older than it actually is, according to new data from NASA’s Chandra X-ray Observatory. This discovery shows how a massive planet can affect the behavior of its parent star. The star, WASP-18, and its planet, WASP-18b, are located about 330 light-years from Earth. WASP-18b has a mass about 10 times that of Jupiter and completes one orbit around its star in less than 23 hours, placing WASP-18b in the “hot Jupiter” category...

exoplanet sun wobble
2014-09-16 04:19:22

April Flowers for redOrbit.com - Your Universe Online It would seem like a star couldn't be affected by anything less than another star, but new evidence from Cornell University reveals that "hot Jupiters," or large gaseous exoplanets, can cause their host stars to wobble as the planets wind their way through their own solar systems to snuggle up against their suns. "Although the planet's mass is only one-thousandth of the mass of the sun, the stars in these other solar systems are...

plasma during magnetic reconnection
2014-09-14 02:30:26

John Greenwald, Princeton Plasma Physics Laboratory Magnetic reconnection can trigger geomagnetic storms that disrupt cell phone service, damage satellites and blackout power grids. But how reconnection, in which the magnetic field lines in plasma snap apart and violently reconnect, transforms magnetic energy into explosive particle energy remains a major unsolved problem in plasma astrophysics. Magnetic field lines represent the strength and direction of magnetic fields. Now scientists...

Karen C. Fox, NASA's Goddard Space Flight Center Underscoring the vast differences between Earth and its neighbor Venus, new research shows a glimpse of giant holes in the electrically charged layer of the Venusian atmosphere, called the ionosphere. The observations point to a more complicated magnetic environment than previously thought – which in turn helps us better understand this neighboring, rocky planet. Planet Venus, with its thick atmosphere made of carbon dioxide, its...

solar flare
2014-09-11 03:30:23

Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT on Sept. 10, 2014. NASA's Solar Dynamics Observatory captured images of the event. 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. [...

Jacqueline Faherty, Carnegie Institution A team of scientists led by Carnegie's Jacqueline Faherty has discovered the first evidence of water ice clouds on an object outside of our own Solar System. Water ice clouds exist on our own gas giant planets--Jupiter, Saturn, Uranus, and Neptune--but have not been seen outside of the planets orbiting our Sun until now. Their findings are published Tuesday, Sept. 9 by The Astrophysical Journal Letters and are available here. At the Las Campanas...

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...
