Centaurus A, a galaxy about 11 million light-years away, takes on the shape of a whirling dervish in this spectacular composite image of the raw power generated by the supermassive black hole at its core. Jets and lobes (orange) powered by the black hole, which is millions of times the mass of our sun, were imaged by the Atacama Pathfinder Experiment (APEX) telescope in Chile. X-rays (blue) were seen by the orbiting Chandra X-ray Observatory. Visible light data, from the Wide Field Imager on the Max-Planck/ESO 2.2-meter telescope, also in Chile, shows the dust lane in the galaxy, as well as background stars. The x-ray jet in the upper left extends for about 13,000 light-years from the black hole. Material in the jet is travelling at about half the speed of light.

Yeah, that too. : )

Nice Adriana. It is so just so damn difficult to wrap your mind around how BIG space is.

Perseid meteor shower 2010 arrives to light up the night sky

Published: Wednesday, August 11, 2010

A Perseid meteor streaks across the sky early August 12, 2008 near Rogers Spring in the Lake Mead National Recreation Area, Nevada.

Star-gazers may be in for a treat over the next few nights, so long as mother nature agrees to play nice.

The Perseid meteor shower, a yearly spectacle that returns every August to fill the sky with streaks of light, is due to arrive tonight and peak Thursday, according to NASA.

But the National Weather Service predicts a cloudy covering across New Jersey tonight, and thunderstorms Thursday. Expect temperatures to dip into the mid-70s, allowing for a pleasant evening of shooting stars — provided those watching can stay dry.

The Serin Observatory at Rutgers in Piscataway will be holding a public viewing Thursday night from 9 to 11 p.m., and the Simpson Observatory in Princeton will hold one Friday night from 8 to 11 p.m., if weather permits.

The name "shooting stars" is a misnomer — meteor showers are caused by dust from comets colliding with Earth's atmosphere at high speeds, according to NASA. The particles in the Perseid shower come from the Swift-Tuttle comet.

The name Perseid comes from the constellation Perseus, located in the northeast sky. All of the tails following the shooting stars will point back to an origin point located near the constellation in the sky, NASA says. The actual origin, they clarify, is in our own solar system, nowhere near the stars that make up Perseus.

For those planning to enjoy the show, NASA provides a few suggestions:

• Get as far away from urban light pollution as possible and find a location with a clear, unclouded view of the night sky.

• Search for the darkest patch of sky you can find, as meteors can appear anywhere overhead.

• Plan to be patient and watch for at least half an hour. A reclining chair or ground pad will make it far more comfortable to keep your gaze on the night sky.

• Put away the telescope or binoculars. Let your eyes hang loose and don't look in any one specific spot. Relaxed eyes will quickly zone in on any movement up above.

• Avoid looking at your cell phone or any other light. Both destroy night vision. If you have to look at something on Earth, use a red light.

Mary Roach on Packing for Mars
Thursday, August 05, 2010

Mary Roach explores the strange universe of space travel. In Packing for Mars: The Curious Science of Life in the Void, she looks at the science of preparing for life in space—a world devoid of the things we need to survive: air, gravity, hot showers, and fresh foods. She investigates what happens if you vomit in your helmet during a space walk and if its possible for the human body to survive a bailout at 17,000 miles per hour.

Solar Tsunami! Celestial Show to Hit Earth Tonight
By: Madison Gray
Tuesday, August 3, 2010

A gargantuan eruption of plasma on the surface of the sun has caused a celestial tsunami shower of ionized atoms to head straight for the Earth, which scientists expect to arrive at our planet Tuesday night.

Scientists also say there is nothing we can do and the coronal mass ejection will hit our world, illuminating the night sky before a final collision between us and the inevitable geomagnetic storm. "It's the first major Earth-directed eruption in quite some time," Leon Golub of the Harvard-Smithsonian Center for Astrophysics told Space.com.

And besides causing problems with satellites in the way, it should be quite an entertaining show.

NASA's Solar Dynamics Observatory, which was launched in February and studies space phenomena like this one, and looks into the sun to see how it works. Scientists there say people in the Northern U.S. have a great view of it, and it should be even better if it triggers aurorae, or solar particles coming into contact with earth's magnetic field and our atmosphere.
