For the first time ever, scientists are witnessing the formation of a new moon as it forms within Saturn’s outer rings. According to a recent report, NASA’s Cassini spacecraft recently discovered this icy formation, currently being called “Peggy,” on April 15th as it disturbed the smooth lines of the ring system. But will it grow any larger, leave the ring system, or will it fizzle out and break apart?

First Lunar Eclipse of 2014
These photos were shot in south Baton Rouge on Tuesday morning at 2:45 am. This eclipse marked the beginning of a tetrad, a series of four total lunar eclipses in a row. The next three total eclipses will be occurring on Oct. 8, 2014, April 4, 2015, and the final occurring on Sept. 28, 2015.
The ‘ghosting’ is the rapid movement of the clouds during a 2 second exposure.
Below the moon is Spica, in the constellation Virgo, and Mars is further west(right) in the shots.
I expect to have better photos after the next eclipse… weather permitting. Ha.
SpaceX-3 Commercial Resupply Services flight and Grasshopper test
Mission: SpaceX-3 Commercial Resupply Services flight
Launch Vehicle: Falcon
Launch Site: Cape Canaveral Air Force Station, Florida
Launch Date: April 14, 4:58 p.m. EDT
NASA’s International Space Station resupply mission includes the legs for Robonaut, OPALS Lasercomm experiment and much more. I think, however, the most exciting and dramatic portion of the flight is the possible test of the ‘Grasshopper’ reusablility system.
Read the detailed story of the SpaceX Grasshopper program.

The launch will be webcast live, with commentary from SpaceX corporate headquarters in Hawthorne, CT at spacex.com/webcast and NASA’s Kennedy Space Center at www.nasa.gov/nasatv.

Total Lunar Eclipse – April 15
Take a late night break from doing your taxes!
View an eclipse of the moon on April 15!
April 15 – 2 am. Central Time
In the morning of Tuesday, April 15, the full moon will pass through earth’s shadow producing a total lunar eclipse visible across North America. Lunar eclipses are perfectly safe to view, and an exciting family event.
The total lunar eclipse phase begins at 02.06 am when the edge of the moon first enters the darkest part of earth’s shadow. The moon will be completely within the shadow for 78 minutes, ending at 3.34 am.
For people in the United States, this eclipse is the first in an extraordinary series of lunar eclipses in what astronomers call a lunar eclipse tetrad—a series of four consecutive total eclipses occurring at approximately six month intervals. The total eclipse of April 15 will be followed by another on Oct. 8, 2014, and another on April 4, 2015, and another on Sept. 28 2015. All four total eclipses will be visible over most of the U.S. Although lunar eclipse tetrads are rare, they have frequently occurred in the past and there are nine sets of tetrads occurring during the 21st century.
On average, lunar eclipses occur about twice a year, but not all of them are total. There are three types:
A penumbral eclipse is when the moon passes through the pale outskirts of earth’s shadow. It’s so subtle that sky watchers often don’t notice an eclipse is underway.
A partial eclipse is more dramatic. The moon dips into the core of earth’s shadow, but not all the way, so only a fraction of moon is darkened.
A total eclipse, when the entire moon is shadowed, is best of all. The face of the moon turns sunset-red for up to an hour or more as the eclipse slowly unfolds.
Usually, lunar eclipses come in no particular order. A partial can be followed by a total, followed by a penumbral, and so on. Anything goes. Occasionally, though, the sequence is more orderly. When four consecutive lunar eclipses are all total, the series is called a tetrad.
Weather permitting; this Tuesday’s total eclipse will turn the moon red. Why red?
Total lunar eclipses occur only when the moon passes completely through the shadow of the earth, and if you imagined yourself standing on the dusty lunar surface during just an eclipse and looking up at the sky, the shadow of the earth would completely block out the sun. You might expect earth seen in this way to be utterly dark, but it’s not. The rim of the planet is on fire! As you scan your eye around earth’s circumference, you’re seeing every sunrise and every sunset in the world, all of them, all at once. This incredible light beams into the heart of earth’s shadow, filling it with a coppery glow and transforming the moon into a great red orb.
Mark your calendar for April 15th and let the tetrad begin.
Mars Will Be Extra Bright In The Sky Tonight
Tonight you might go out and see an extra bright orange dot in the sky. Well, that’s not a star you’re seeing, that’s Mars.
Discovery: The Great Pink Planet
I’m well aware of what today is. Believe me, I debated on whether or not to make a fake April Fools Day blog posting along the lines of “NASA announces the discovery of intelligent life on planet Eps Eri 04-01a,” or “50,000 year old space ship discovered in Antarctica.” However, there’s stuff out there in space that’s real and strange enough to bring to light without having to result in phoney gags. For example, a couple of days back I heard about the discovery of a pink planet way out in space. So here’s the rundown on the lowest-mass planet ever detected around a star like the sun, GJ 504b that just happens to be pink.
