Mercury History Masked Volcanic Activity
2013-07-05 11:03:48

Brett Smith for redOrbit.com - Your Universe Online Ever since NASA's Mariner 10 sent back the first images of Mercury, scientists have been fascinated by the planet's unusually smooth surface. According to an analysis of images provided by NASA's Mercury-orbiting MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging), a period of heavy volcanic activity essentially gave the planet a makeover about 4 billion years ago, erasing the first 400 to 500 million years of its...

MESSENGER Team Names Ten Major Fault Scarps On Mercury
2013-06-08 08:29:31

April Flowers for redOrbit.com -- Your Universe Online Recently, the MESSENGER Science Team proposed names for 10 rupes on Mercury. The International Astronomical Union (IAU), which has been the arbiter of planetary and satellite nomenclature since 1919, approved the names. In keeping with the theme of naming rupes on Mercury, they all bear the names of ships of discovery. Rupes is the Latin word for cliff, which perfectly suits the formations on Mercury. They are long cliff-like...

A new level of variation in messenger RNAs exposed Like musicians in an orchestra who have the same musical score but start and finish playing at different intervals, cells with the same genes start and finish transcribing them at different points in the genome. For the first time, researchers at EMBL have described the striking diversity of messenger RNAs (mRNAs) that such start and end variation produces, even from the simple genome of yeast cells. Their findings, published today in...

Three Coronal Mass Ejections And A Solar Flare In Three Days On The Sun
2013-04-22 11:25:57

Lawrence LeBlond for redOrbit.com - Your Universe Online NASA´s Solar Dynamics Observatory (SDO) recorded a coronal mass ejection (CME) on Saturday April 20, 2013, at 2:54 a.m. EDT. That was only to be the first of three such events over the course of the weekend. CME´s, solar phenomena that send billions of tons of solar particles and radiation speeding through space at over 500 miles per second, have the potential to affect communication systems and electronics here and in...

On March 17, 2013, MESSENGER successfully completed its year-long first extended mission in orbit about Mercury, building on the groundbreaking scientific results from its earlier primary mission. Today the team is poised to embark on a second extended mission that promises to provide new observations of Mercury's surface and interior at unprecedented spatial resolution and of the planet's dynamic magnetosphere and exosphere at high time resolution during the peak and declining phase of the...

The Planet Mercury -- in astronomy, nearest planet to the sun, at a mean distance of 36 million mi (58 million km); its period of revolution is 88 days. Mercury passes through phases similar to those of the moon as it completes each revolution about the sun, although the visible disk varies in size with respect to its distance from the earth. Because its greatest elongation is 28, it is seen only for a short time after sunset or before sunrise. Since observation of Mercury is...
