Do You Love the Color of the Sun?
Get dazzled by the true spectrum of solar beauty. From fiery reds to cool blues, explore the vibrant hues of the Sun in a mesmerizing color order. The images used to make this gradient come from our Solar Dynamics Observatory. Taken in a variety of wavelengths, they give scientists a wealth of data about the Sun.
Don't miss the total solar eclipse crossing North America on April 8, 2024. (It's the last one for 20 years!) Set a reminder to watch with us.

Alien bars tend to be reasonably friendly. But this Space Crowd Saturday, we have a more lively example of the genre with Keith Parkinson's 1994 cover to Harry Harrison's anthology Galactic Dreams.

Tiny BurstCube's Tremendous Travelogue
Meet BurstCube! This shoebox-sized satellite is designed to study the most powerful explosions in the cosmos, called gamma-ray bursts. It detects gamma rays, the highest-energy form of light.
BurstCube may be small, but it had a huge journey to get to space.
First, BurstCube was designed and built at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Here you can see Julie Cox, an early career engineer, working on BurstCube’s gamma-ray detecting instrument in the Small Satellite Lab at Goddard.
BurstCube is a type of spacecraft called a CubeSat. These tiny missions give early career engineers and scientists the chance to learn about mission development — as well as do cool science!
Then, after assembling the spacecraft, the BurstCube team took it on the road to conduct a bunch of tests to determine how it will operate in space. Here you can see another early career engineer, Kate Gasaway, working on BurstCube at NASA’s Wallops Flight Facility in Virginia.
She and other members of the team used a special facility there to map BurstCube’s magnetic field. This will help them know where the instrument is pointing when it’s in space.
The next stop was back at Goddard, where the team put BurstCube in a vacuum chamber. You can see engineers Franklin Robinson, Elliot Schwartz, and Colton Cohill lowering the lid here. They changed the temperature inside so it was very hot and then very cold. This mimics the conditions BurstCube will experience in space as it orbits in and out of sunlight.
Then, up on a Goddard rooftop, the team — including early career engineer Justin Clavette — tested BurstCube’s GPS. This so-called open-sky test helps ensure the team can locate the satellite once it’s in orbit.
The next big step in BurstCube’s journey was a flight to Houston! The team packed it up in a special case and took it to the airport. Of course, BurstCube got the window seat!
Once in Texas, the BurstCube team joined their partners at Nanoracks (part of Voyager Space) to get their tiny spacecraft ready for launch. They loaded the satellite into a rectangular frame called a deployer, along with another small satellite called SNoOPI (Signals of Opportunity P-band Investigation). The deployer is used to push spacecraft into orbit from the International Space Station.
From Houston, BurstCube traveled to Cape Canaveral Space Force Station in Florida, where it launched on SpaceX’s 30th commercial resupply servicing mission on March 21, 2024. BurstCube traveled to the station along with some other small satellites, science experiments, as well as a supply of fresh fruit and coffee for the astronauts.
A few days later, the mission docked at the space station, and the astronauts aboard began unloading all the supplies, including BurstCube!
And finally, on April 18, 2024, BurstCube was released into orbit. The team will spend a month getting the satellite ready to search the skies for gamma-ray bursts. Then finally, after a long journey, this tiny satellite can embark on its big mission!
BurstCube wouldn’t be the spacecraft it is today without the input of many early career engineers and scientists. Are you interested in learning more about how you can participate in a mission like this one? There are opportunities for students in middle and high school as well as college!
Keep up on BurstCube’s journey with NASA Universe on X and Facebook. And make sure to follow us on Tumblr for your regular dose of space!

To some it looks like a cat's eye. To others, like a giant cosmic conch shell. This is actually one of the brightest and most highly detailed planetary nebula known- the Cats Eye Nebula. It is composed of gas expelled in the brief yet glorious phase near the end of life of a Sun-like star. This nebula's dying central star may have produced the outer circular concentric shells by shrugging off outer layers in a series of regular convulsions. The formation of the beautiful inner structures, however, is not well understood. The featured image is a composite of a digitally sharpened Hubble Space Telescope image with X-ray light captured by the orbiting Chandra Observatory. The exquisite nebula spans over half a light-year across. Of course, by gazing into this Cat's Eye, humanity may well be seeing the fate of our sun, destined to enter its own planetary nebula phase of evolution ... in about 5 billion years.
