Why Is There a Goddess’ Egg Floating In Space? [Space]

This image reminds me of an ovum—a female egg. But it’s not inside anything on Earth. It’s floating in the vastness of space about 9,000 light years from here, in the constellation of Cassiopeia. It’s the Tycho supernova remnant. More »

Catch Up on the Past 9 Billion Years of the Universe’s Existence in 80 Seconds [Video]

Ever wonder what the universe was really up to 5.5 billion years ago? It was almost certainly expanding, but now with a new Harvard-developed technology called Arepo, you can watch the beautiful, violent unfolding of the universe for yourself. Just don’t think too hard about it. You might suffer a nervous breakdown trying to justify your existence. [Harvard via PhysOrg via Engadget] More »

Space Shuttles Atlantis and Endeavour Meet Nose-to-Nose One Last Time

It’s more the little sad to many fans of space travel in the US that the space shuttle program has been retired. Right now American astronauts have no way to reach the International Space Station or leave Earth other than catching a ride with astronauts from other countries on their spacecraft. Another depressing final milestone in the shuttle program has been met this week with the last multiple shuttle shuffle of the program.

space meet

The space shuttles Atlantis and Endeavour met nose-to-nose briefly for the final time for photos as they were moved between the vehicle assembly building and orbiter processing facility at Cape Canaveral in Florida. Atlantis was moved for the final time to be transformed from a flight-ready shuttle to a display to be put into a museum.

Presumably, the transformation has to do with removing any potentially hazardous materials from the shuttle. Atlantis should be delivered to the Kennedy Space Center visitor complex where it will spend the remainder of its days starting this November 2. Endeavour will end up at the California Science Center once it’s made museum-ready.

We Were Totally Wrong About the Sun’s Shape Until Yesterday [Space]

For as long as we’ve bothered to care about heavenly bodies other than our own, we’ve thought that the size of the Sun varies throughout its 11-year solar cycles. Intense magnetic forces, the theory went, rendered it as malleable as a sturdy stress ball. That was a good theory, backed up by decades of data. More »

Scientists discover our sun is rounder than they thought

I am no astronomer or scientist for sure, but this side of the occasional solar flare; I’ve always presumed our sun to be round. Scientists have recently announced that the shape of our sun is rounder then they previously believed. The scientists also said that the sun is squashed more often than previously believed, making it wider in the middle than at the poles.

Previously, astronomers presumed the shape of the sun changed along with its solar cycle. The thought was that the flow of matter inside the sun, and in its atmosphere, would shift over time due to magnetic activity and in turn change the shape of our star. It sounds strange but researchers have apparently been challenged for the last 50 years to accurately measure the sun’s shape.

NASA scientists using my Solar Dynamics Observatory have measured the solar shape over a two-year period spanning 2010 through 2012. During this period, the sun evolved from a minimum sunspot activity to a maximum sunspot activity during its solar cycle. Researchers on the project discovered that the sun’s slightly flat shape with a wide equator and a shorter distance between the polls is surprisingly stable and almost completely unaffected by the solar cycle.

The implication of this discovery is that the shape of the sun is controlled by fundamental properties of the star rather than by magnetism, which can vary significantly. Despite being slightly flattened, the scientists say that the sun is still rounder than they theorized. Future research on measuring the shape of the sun more accurately will help scientists determine how oscillations deep inside the sun manifest on its surface.

Scientists create simulation of the universe, reenact 14 billion years in a few months (video)

Scientists create simulation of the universe, reenact 14 billion years in a few months

Are animations of Curiosity’s Mars landing not enough to feed your space exploration appetite? Try this on for size: a group of scientists from the Harvard-Smithsonian Center for Astrophysics and the Heidelberg Institute for Theoretical Studies have generated what’s billed as a full-fledged simulation of the universe. Arepo, the software behind the sim, took the observed afterglow of the big bang as its only input and sped things up by 14 billion years. The result was a model of the cosmos peppered with realistically depicted galaxies that look like our own and those around us. Previous programs created unseemly blobs of stars instead of the spiral galaxies that were hoped for because they divided space into cubes of fixed size and shape. Arepo’s secret to producing accurate visualizations is its geometry; a grid that moves and flexes to mirror the motions of dark energy, dark matter, gasses and stars. Video playback of the celestial recreation clocks in at just over a minute, but it took Harvard’s 1,024-core Odyssey super computer months to churn out. Next on the group’s docket is tackling larger portions of the universe at a higher resolution. Head past the jump for the video and full press release, or hit the source links below for the nitty-gritty details in the team’s trio of scholarly papers.

Curiosity survives brain transplant, prepares for first drive

Curiosity survives 'brain transplant,' prepares for first drive

If you thought your OTA update took too long, how about four days? That’s how long the Curiosity “brain transplant” took, and is now finally complete. This now means that the main computers have switched over from landing mode, to surface mode — and thus we hope — meaning the rover’s good to go. That said, it’s still a painfully slow process, with Curiosity’s wheels likely remaining steadfastly motionless for at least another week — and even then we’re looking at a trip of just a few meters. When it comes to interplanetary travel, though, slow and steady definitely wins the race — in the meantime, you can soak up the view.
