Watch ULA’s March 25 Delta Launch Live – details below
Update 3/26: 2 new names have been added to the voting list – Zeus and Vulcan !
United Launch Alliance (ULA) is asking the public for your help in naming their new American made rocket, now under development that “represents the future of space”- and will replace the firms current historic lines of Atlas and Delta rocket families that began launching back near the dawn of the space age.
Eagle, Freedom or GalaxyOne – those are the names to choose from for the next two weeks, from now until April 6.
UPDATE 3/26: 2 new names have been added to the voting list – Zeus and Vulcan ! [click to continue…]
Color Crazy. Short time exposure of the star Sirius photographed through a small telescope. I tapped the tube to make the star bounce around, recording the star’s continuous and rapid color changes as it twinkled. Refraction of the star’s light by our turbulent atmosphere breaks it up into every color of the spectrum. Credit: Bob King
We all have cameras, and the sky’s an easy target, so why not have a little fun? Ever since I got my first camera at age 12 I wanted to shoot time exposures of the night sky. That and a tripod are all you need. Presented here for your enjoyment are a few oddball and yet oddly informative images of stars and planets. Take the word “art” loosely! [click to continue…]

What does a solar eclipse look like from a fast-flying Falcon 7X jet at 14,000 meters (48,000 feet)? French journalist Guillaume Cannat described the Sun as looking black and “ruffled.”
Cannat was part of a group accompanying professional and amateur astronomers on board three Dassault Falcon 7X executive jets that flew in the narrow zone where totality of the eclipse could be observed, from southern Greenland to the geographic North Pole. Traveling through the stratosphere provided the unique opportunity to watch the total eclipse without atmospheric turbulence — which improved the view and the ride. And flying at speeds near Mach .9 also “lengthened” the view of the eclipse to over a minute.

“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars,” Carl Sagan famously said in his 1980 series Cosmos. “We are made of starstuff.”
And even today, observations with NASA’s airborne SOFIA observatory are supporting this statement. Measurements taken of the dusty leftovers from an ancient supernova located near the center our galaxy – aka SNR Sagittarius A East – show enough “starstuff” to build our entire planet many thousands of times over.
“Our observations reveal a particular cloud produced by a supernova explosion 10,000 years ago contains enough dust to make 7,000 Earths,” said research leader Ryan Lau of Cornell University in Ithaca, New York – the same school, by the way, where Carl Sagan taught astronomy and space science.
At the turn of the 20th Century, Einstein’s theory of relativity stunned the physics world, but the experimental evidence needed to be found. And so, in 1919, another respected astronomer, Arthur Eddington, observed the deflection of stars by the gravity of the Sun during a solar eclipse. Here’s the story of that famous experiment.

You’ve had a busy day wandering around a faraway part of our solar system. It’s time to put your head down for a nap. Where do you place it? According to Erik Seedhouse in his book “Bigelow Aerospace: Colonizing Space One Module at a Time“, you easily slip into a space module, doff your all-purpose space suit and enjoy the pleasures of a safe secure environment. Know of a better way to get over that stressful day? [click to continue…]
Nova Sagittarii 2015 No. 2 in the Sagittarius “Teapot”was easily visible with the naked eye at magnitude +4.4 when this photo was taken today March 21. The nova has been steadily brightening since its discovery less than a week ago. Credit: Bob King
Great news about that new nova in Sagittarius. It’s still climbing in brightness and now ranks as the brightest nova seen from mid-northern latitudes in nearly two years. Even from the northern states, where Sagittarius hangs low in the sky before dawn, the “new star” was easy to spy this morning at magnitude +4.4.
While not as rare as hen’s teeth, novae aren’t common and those visible without optical aid even less so. The last naked eye nova seen from outside the tropics was V339 Del (Nova Delphini), which peaked at +4.3 in August 2013. The new kid on the block could soon outshine it if this happy trend continues.

The weather is always fine in Southern Spain…except during eclipse days!” Legault told Universe Today via email. “I had to drive a lot trying to find clear skies, finally the sky was covered with thick high clouds but I got the ISS passing in front of the Moon during the eclipse.”
