nasa How blue-tiful! 🤩🌌
Near the outskirts of the Small Magellanic Cloud, a satellite galaxy about 200 thousand light-years away, lies this 5 million year young and dazzling star cluster known as NGC 602. Inside the star cluster, bright, blue, newly formed stars are blowing a cavity in this nebula, sculpting the inner edge of its outer portions, slowly eroding it away and eating into the material beyond. Star formation started at the center of the cluster and propagated outward, with the youngest stars still forming today along the dust ridges.
Fun fact: Did you know that the color of a star is directly linked to its surface temperature? The hotter the star, the shorter the wavelength of light it will emit. The hottest of stars are blue or blue-white and the cooler ones are red or red-brown.
What color star would you be?
nasa Get in loser, we're going stargazing 🌌
Magnetic fields in Messier 82, or the Cigar galaxy, are shown here as lines over a visible light and infrared composite image of the galaxy from the @NASAHubble & the Spitzer Space Telescope.
The galaxy located in the constellation Ursa Major is remarkable. Stellar winds streaming from hot new stars form a galactic super wind that blasts out plumes of hot gas (red) and a huge halo of smoky dust (yellow/orange) perpendicular to the narrow galaxy (white). Researchers used the Stratospheric Observatory for Infrared Astronomy ( @sofiatelescope ) magnetic field data and tools that have been used extensively to study the physics around the Sun to extrapolate the magnetic field’s strength 20,000 lights-years around the galaxy.
The highways appear to extend indefinitely into intergalactic space, like the Sun’s solar wind, and may help explain how the gas and dust have traveled so far away from the galaxy.

The seven-member Expedition 64 crew takes a moment to pose for a quick portrait inside the @ISS ’ Kibo laboratory module from @jaxajp (Japan Aerospace Exploration Agency). Expedition 64 began in back in October 2020 with focused research investigations on biology, Earth science, human research, and more to provide the foundation for continuing human spaceflight beyond low-Earth orbit to the Moon and Mars!

nasa 🤯 Discovery alert: We don’t know of many planets quite like this!
Thanks to data from our @NASAGoddard TESS mission, a planet existing around THREE stars has been confirmed, after a hefty hunt that spanned about 11 years!
It all started shortly after NASA's Kepler mission began operations in 2009, when it identified what was thought to be a planet about the size of Neptune later known as KOI-5Ab. The planet which was the second new planet candidate to be found by the mission, was ultimately forgotten as Kepler racked up planet discoveries. Now, the chief scientist of NASA’s Exoplanet Science Institute says he has “resurrected KOI-5Ab from the dead!" and we are so glad he did.
Planet KOI-5Ab (shown here transiting across the face of a sun-like star), is located 1,800 light-years away in the Cygnus constellation. It is about one half the mass of Saturn & orbits a star (star A) with a relatively close companion (star B). Star A and star B orbit each other every 30 years. A third gravitationally bound star (star C) orbits stars A and B every 400 years.

nasa It’s more than a feeling 🎵
Much like the delicate filaments of a spider's web, the glowing lights of the city of Boston seemingly spread from a central point in this image taken by the crew of the @ISS as it orbited 263 miles above Earth's surface.
What city would you want to look at if you were fluttering about in space on a Friday in January?
nasa Bon Voyage, #Cygnus ! 🦾
Yesterday, about three months after delivering nearly 8,000 pounds (3,628 kilograms) of scientific experiments, supplies, commercial products, hardware, and more to the @ISS , @NorthropGrumman ’s uncrewed Cygnus cargo spacecraft departed the orbiting lab. Flight controllers on the ground sent commands to use the @CanadianSpaceAgency 's Canadarm2 robotic arm to robotically detach Cygnus from the Earth-facing port of the unity module and maneuver it into place.
Before the craft took off, the crew packed Cygnus with the Saffire V investigation & the SharkSat hosted payload to be conducted during an extended mission in orbit. It'll complete a series of milestones to move away safely & remain in orbit until Jan. 26, for an extended mission with science experiments.

nasa Double take: Do you see a face or a hand?
When this image from @nasachandraxray of PSR B1509-58 – a spinning neutron star surrounded by a cloud of energetic particles about 17,000 light-years from Earth – was released in 2009, it created a ton of hype because people saw a hand-like shape in the X-ray emission. Pareidolia vibes were strong.
X-rays from Chandra in gold are seen along with infrared data from NASA's Wide-field Infrared Survey Explorer (WISE) telescope in red, green and blue. Pareidolia struck again as others reported seeing a shape of a face in WISE's infrared data.
So... can you help us settle the debate? what do YOU see? Vote using the "✋" or "🙂" in the comments below!

nasa 🎵Sun in the sky, you know how I feel 🌅
While each & every sunrise literally marks the beginning of a brand new day, it also reminds us all that we, too, can start fresh with a good attitude, positivity, and gratitude. We are all about that for 2021 and beyond.
In a region often shrouded in clouds, this sunglint photograph was snapped by an Expedition 56 crew astronaut aboard the @ISS who focused a camera lens on the Sun’s reflection point, about 1050 miles to the northeast of the spacecraft’s position over Massachusetts. The photograph shows the horizon and coastline of the Canadian provinces of Newfoundland and Labrador, with Quebec further inland. Flying towards the sunrise looks magical: the feeling of speed, the Earth rotating below and the ISS humming, and then a massive burst of vibrant light. Let's go?
nasa 🔭 As you soak in the feeling of a new year, here’s what you can look forward to in the sky this January:
▪️ Earth’s closest approach to the Sun
▪️ Uranus visible on Jan. 20
▪️ A glimpse of Mercury mid-month
Enjoy these cosmic treats and more with our skywatching tips!

nasa 🎇 Goodbye 2020. Hello 2021❗
Have you ever seen a slow-motion firework show that lasted… well over 150 YEARS? Meet Eta Carinae. Eta Carinae, shown here in a @NASAHubble image is a doomed super-massive star 7,500 light-years away that went through a “Great Eruption” in the 1840s that made it the second-brightest visible star in the sky for over a decade — it was so bright that sailors at the time used it as an important navigational star in the southern seas.
The coming year is packed with amazing science and we couldn’t be more thrilled to have each of you along for the ride! From all of us here at NASA, we thank you for your unwavering support, resilience, and motivation. 🚀
