It would be cool if one would be able to hear that as they passed by Jupiter, but outer space is a vacuum, and the sound frequencies are so low they're inaudible with the human ears alone. Voyager was equipped with some sound wave-capturing technology.

The European Southern Observatory recently took a very nice image of the Sculptor Galaxy. The story is here:

On June 18, 1983, a young physicist from California took her seat aboard the space shuttle and launched into history. On that date, Sally Ride became the first American woman in space as a mission specialist on STS-7. In this image Ride monitors control panels from the pilot's chair on the Flight Deck.

Technicians at NASA's Kennedy Space Center in Florida will complete the payload premate test for space shuttle Discovery this weekend, along with working on the shuttle's heat shield.

The STS-133 astronauts will focus on administrative activities Friday as their training continues for the mission targeted to launch in September.

For those who haven't heard of it, VY Canis Majoris is the largest known star in the universe. It's 4,900 light years away, and is 2,100 times the solar radii of the Sun.

Here's a size comparison between the Earth and the Sun:

That is one BIG motherfucker.

This is a fantastic image. It's a pictoral size reference guide to various celestial bodies in order of size. It starts with the smallest planet (Mercury), up to the largest star (VY Canis Majoris).

Betelgeuse (pronounced like Beetlejuice) is the largest celestial body I've seen through a telescope [and knew what I was looking at]. It's a red supergiant star that is currently in its dying stages, and will become a supernova within a couple millennia.

Dammit, I can't see it with FF. Something about not having a WMP11 plugin. :roll:

VY Canis Majoris is 2,000 times the radius of the sun, but has only about 20 times as much mass, so it's density is actually extremely low; its gravitational pull is probably only twice that of Earth's.

Workers at NASA's Kennedy Space Center in Florida are focusing on Freon coolant loops in space shuttle Discovery in preparation for top-off and sampling work that will begin tomorrow. Tomorrow also will see the conclusion of the payload premate test that began last week.

STS-133 Commander Steve Lindsey and his crew are simulating an undocking and flyaround of the International Space Station as part of their training for the upcoming mission, targeted to launch in September.

Today, our sun reaches its northernmost point in planet Earth's sky. Called a solstice, the date traditionally marks a change of seasons -- from spring to summer in Earth's Northern Hemisphere and from fall to winter in Earth's Southern Hemisphere. In this image from 2007, NASA's Solar TErrestrial RElations Observatory (STEREO) satellites provided the first three-dimensional images of the sun. STEREO, a two-year mission that launched October 2006, provided a unique and revolutionary view of the Sun-Earth System. Image Credit: NASA/JPL-Caltech/NRL/GSFC

Stephen Colbert is going through astronaut training this week on his show. Very humorous. Especially since he asks every person he meets if they've had sex in space.
