Planck All Sky Survey - Image of the Week

Wed, 07/21/2010 - 08:00

In this age of technological revolution new satellites and observatories are being launched every year. And usually one of the first tasks undertaken is what is known as an all sky survey. In essence, the observatory takes a quick view of the entire sky -- or at least the entire sky that is available to it in the case of ground based observatories. These surveys are good for getting a general view of what the Universe looks like in the observatory's frequency band, as well as potentially identifying previously unknown sources.

NASA Moves Final Two Shuttle Launch Dates

Fri, 07/16/2010 - 08:00

I reported several weeks ago that NASA was contemplating moving the final two shuttle launches, possibly pushing them into 2011. Well, now it is official.

It now appears that November 1 and February 26 are the target dates for the launches. NASA says that the delays are due to an examination of the payload requirements of the flights, and determining that they could not prepare everything in time under the old time table.

Scientists "See" Black Hole Feeding on Galaxy

Thu, 07/01/2010 - 03:02

Black holes, by nature, are difficult to observe. Typically, measurements are made by detecting gravitational interactions with surrounding objects. Also, jets of material can be seen streaming from the poles of some black hole systems (see above image of jets from the supermassive black hole at the center of the galaxy Centaurus A). But neither of these methods allow for direct detection of the local environment around the object.

The Calm Before the Storm?

Tue, 06/29/2010 - 06:27

The Sun undergoes seasons of varying activity, where the frequency of sunspots and solar flares rise and wane. Typically there is an 11 year period between peaks of maximum and minimum activity. However, this most recent minimum -- which some believe we are finally coming out of -- was been quite unusual.

What Earth's Atmosphere Looks Like From Space - Image of the Week

Fri, 06/18/2010 - 07:55

The new image of the week was taken as astronauts aboard the International Space Station looked west at the setting Sun. Of course it is quite a different experience for them as they see 16 Sun rises and Sun sets every day due to the incredible velocity (roughly 17,000 miles per hour) that they orbit the Earth.

SpaceX Successfully Launches Privately Funded Rocket

Tue, 06/08/2010 - 12:45

Late last week the Space Exploration Technologies Corporation, commonly known as SpaceX, completed a test of their new Falcon 9 rocket. The rocket blasted into space and successfully placed a crew module into orbit. While there are still many tests to be done, and new systems to be created (such as an emergency escape system) before a manned flight is possible, this was an important first step in creating a privately funded space program.
