Ever wonder what astronauts eat on Thanksgiving while they’re in orbit? (Spoiler alert: It doesn’t look too appetizing.) Skip to the two-minute mark for some weightless fun with food.
Happy Thanksgiving, all!
Did you know that the sun ejects massive bursts of magnetic energy into space? Serious damage is in store for anything in its path. Sometimes, it’s us. While Earth does have a protective shield that deflects solar wind, some radiation will enter our atmosphere. This video shows the cycle of radiation, from its violent release to its importance on Earth.
Curious about the sun’s solar bursts, how big they can get and when they’re most likely to occur? I got you covered.
It feels like forever since we’ve been able to log onto NASA’s website, and even longer since we’ve seen a tweet from one of its affiliated accounts.
Three days into this government shutdown and we’re getting a bit antsy.
Scrolling through Twitter feeds tonight, we found a cool, new campaign that is keeping the lines of science open. On Oct. 1, @RidingRobots tweeted:
People seem to like #ThingsNASAMightTweet. We do!
When a solar flare filled with charged particles erupts from the sun, its magnetic fields sometime break a widely accepted rule of physics. The flux-freezing theorem dictates that the magnetic lines of force should flow away in lock-step with the particles, whole and unbroken. Instead, the lines sometimes break apart and quickly reconnect in a way that has mystified astrophysicists.
Last week, days after the sun released a massive burst of solar wind and magnetic fields toward Earth, the particles collided with our planet’s magnetic field. When the two smash together, they create these amazing displays in the sky.
Green is the most common auroral color, according to Northern Lights Centre.
A pale yellowish-green, is produced by oxygen molecules located about 60 miles above the earth. Rare, all-red auroras are produced by high-altitude oxygen, at heights of up to 200 miles. Nitrogen produces blue or purplish-red aurora.

It’s been awhile since I posted anything about solar flares. (Though, it’s also been awhile since I’ve written about anything in general … Hopefully the astronomy news hanging out in the dark tunnels of my email archive will soon see the light.) Anyway, here’s a video of X-Class solar flares, a first for 2013.
The video was taken earlier this month when, within a 24-hour time period, the sun emitted three fairly large flares.
Neil Armstrong, the first man to walk on the moon, has died. He was 82.
Here’s a video of the historic July 20, 1969 descent onto the moon.
This is the second time in a little over a month that the science community has lost a historic figure in space flight history. Sally Ride – the first American woman in space – died on July 23 at the age of 61.
