🎵 Twinkle, twinkle, little bat!
How I wonder what you’re at!
Up above the world you fly,
Like a tea-tray in the sky. 🎵

Perhaps the Hatter spied this cosmic teacup, captured by Chandra X-ray Observatory (blue) and NASA's Hubble Space Telescope (red and green)? More: https://chandra.si.edu/photo/2019/teacup/

What color do you think the universe is? 🪐

If you mixed together the light from hundreds of thousands of galaxies, you might expect something a little more… celestial. Instead, you’d get this creamy, coffee-colored shade astronomers nicknamed Cosmic Latte.

With a hex code of , it might just be the universe’s unofficial fall color.

Brewing up new stars 🪄

Webb's unique view of the stellar nursery known as NGC 7129 reveals numerous stars formerly hidden in this cosmic cauldron.

Stars begin their life in cold, dense regions of dust and gas, hiding from view of most telescopes. Webb’s high degree of infrared sensitivity allows astronomers to peer through dust to study these baby stars.

In this image, we can see stars in various stages of development. The most mature and massive (about 5-8x the mass of our Sun) is the region’s bright central star. In the cavity on the left, appearing in gold, is the largest demonstration of its impact. The outflows from an earlier stage in the star’s development carve into the dense molecular cloud of hydrogen, and combine with the star’s light, causing it to glow.

The region on the right, represented in red, hides much younger objects than those on the left: protostars. As the protostars accumulate matter and increase mass, they eject outflows of super heated material that interact with matter around the star, creating shocks that cause the textured appearance we see in this image. More protostar outflows are at upper left where a dark shadow is being cast by a protostar disk, visible against the surrounding nebula, depicted in blue.

Seeing these different structures help astronomers study the star lifecycle in various stages, leading to a more complete understanding of our universe.

Sometimes when we look out into the shadowy depths of the cosmos, we find it looking right back.

On this day in 1952, the namesake for our Neil Gehrels Swift Observatory was born. He led development of Swift, a first-of-its-kind satellite designed to automatically repoint itself to study fleeting cosmic explosions called gamma-ray bursts.

Also on this day, but in 2017, NASA's Hubble Space Telescope imaged nebula N44. This complex nebula is filled with glowing gas, dark dust lanes, and stars of different ages. It also hosts a dark, starry gap called a “superbubble,” whose presence is something of a mystery.

Black holes don’t emit light, but the space around them can shine bright!

Data from our NuSTAR telescope, combined with observations from ESA - European Space Agency’s XMM-Newton, helped astronomers study the hot, turbulent regions known as coronae that surround the accretion disks feeding supermassive black holes. By surveying some of the most distant and luminous of these sources, the team constructed the most comprehensive view to date of coronae in black hole-powered galaxies. This research helps us better understand how these regions produce the intense X-ray light that we observe.

Our Swift observatory recently returned to science operations to make the most out of its time in orbit. Let’s look at its Burst Alert Telescope, which was designed to catch powerful but fleeting gamma-ray explosions by watching a sixth of the sky at a time for gamma rays.

Because gamma rays can’t be focused with current technology, Swift’s BAT works differently than typical telescopes. The BAT has a mask made of lead tiles that stop gamma rays, casting shadows on the detectors below.

From the pattern of gamma-ray shadows, the BAT calculates the source’s location and shares it with the science community. From there, Swift can quickly repoint its other two instruments to that object. In its 20+ years in orbit, Swift has observed over 2,000 bursts.

Just last year, Swift researchers released an all-sky catalog using over 13 years of data from the Burst Alert Telescope. The catalog pinpointed more than 1,800 sources including active galaxies, neutron stars, and galaxy clusters.
