Well I've spruced up my new Twitter profile page, though I don't really see how this is going to boost the service, or retain users. There's a bit of an identity crisis over at Twitter HQ these days, hopefully someone puts a firm hand on the tiller soon. However I've been around since March 2009 as my new profile now helpfully tells me, and it was my first foray into social media, so I'll stick with them :-)

It is one of the more massive galaxies known. A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in the northern constellation of Ursa Major. This sharp view of the gorgeous island universe shows off a striking yellow nucleus and galactic disk. Dust lanes, small, pink star-forming regions, and young blue star clusters are embedded in the patchy, tightly wound spiral arms. In contrast, many other spirals exhibit grand, sweeping arms with large star-forming regions. NGC 2841 has a diameter of over 150,000 light-years, even larger than our own Milky Way and captured by this composite image merging exposures from the orbiting 2.4-meter Hubble Space Telescope and the ground-based 8.2-meter Subaru Telescope. X-ray images suggest that resulting winds and stellar explosions create plumes of hot gas extending into a halo around NGC 2841.

About B612 Foundation
"Earth—Planetary Defense: B612 seeks to create a private space mission to discover and track hundreds of thousands of asteroids. Former NASA astronauts Ed Lu and Rusty Schweickart are on a decade-long mission to find a way to stop dangerous asteroids from impacting Earth after seeing our fragile blue planet from space. As engineers and trained space travelers, they know the grave dangers of asteroid impacts – all you have to do is look at the craters on the moon. Ed Lu and Rusty Schweickart are pulling together an expert team to protect Earth."
The Sentinel Mission
Sentinel is a proposed space-based infrared (IR) survey mission to discover and catalog 90 percent of the asteroids larger than 140 meters in Earth’s region of the solar system. The mission should also discover a significant number of smaller asteroids down to a diameter of 30 meters. Sentinel will be launched into a Venus-like orbit around the sun, which significantly improves the efficiency of asteroid discovery during its 6.5 year mission.
