Your backstage pass to the universe and how NASA studies it. Exoplanets, black holes, dark energy, and more!

Greenbelt, MD
For the first time, astronomers directly observed stellar wind flowing from a giant star onto its companion, causing powerful X-ray flares. Data from the XRISM telescope, which is led by @JAXA_en in partnership with @NASA and with contributions from @ESA, revealed the cause. 🧵

With all of its telescopes back to work, our Swift observatory is ready to catch cosmic outbursts! If its Burst Alert Telescope spots a gamma-ray flare, Swift will automatically point its other two telescopes at the site. More on Swift’s current status: go.nasa.gov/4hwD1cF

ALT This animated gif shows the Swift spacecraft orbiting around Earth. Swift, all in silver, looks like a long cylinder, with a boxy shape on one end. Long solar panels sit parallel to the body of the spacecraft on two sides. The view zooms in to show the top portion of the spacecraft. Swift looks toward a faint orange oval that is surrounded by the darkness of space. The orange oval enlarges briefly, then shrinks back down. This is followed by an outburst of light blue spheres signifying a gamma-ray burst. This image is watermarked with “Artist’s concept” and “Credit: Aaron Tohuvavohu.”

This return to normal science operations has caused Swift to resume sinking rapidly. But the Swift team is taking advantage of their remaining time in orbit to gather more information about the universe — including any unexpected events that might pop up.

If this “.” were a black hole, it would have about the mass of Jupiter’s moon Ganymede crammed into it! To become a black hole, it’s not about how much stuff an object has, but how much it’s been smooshed. That's a lot of gravity, period. go.nasa.gov/4dCyPqB

ALT This animation opens with a round black hole character, represented by a black circle with half-circle eyes and two small arms, sitting in the center of a purple background with stylized stars scattered around. A red dot at the center of the black hole is labeled, “Singularity,” and a purple pencil hovers near the bottom left of the black hole. As the animation proceeds, the pencil draws a dotted red circle that encloses the black hole, which is labeled, “Event Horizon.” The pencil swirls into the black hole, since it ventured inside the event horizon. The black hole’s eyes follow the pencil on its movements.

#TBT to Sept. 20, 1979, when NASA’s final High Energy Astronomy Observatory, HEAO 3, launched into space. It mapped the sky in gamma-ray light and made detailed measurements of cosmic ray particles, helping us learn about supernova remnants, distant galaxies, and more.

A planetary nebula can be one of the eeriest places in space, haunted by a dead star. This @NASAWebb image of NGC 6072 showcases a mess of gas and dust expelled by the central star at the end of its life. go.nasa.gov/4iKVwMU

Curling up next to a crackling fire? @NASAWebb and @NASAHubble captured this cosmic scale bonfire in the Cigar Galaxy, M82, no matches needed. The galaxy is in the midst of a burst of intense star formation, likely the result of a galaxy merger. go.nasa.gov/4hl9z9z

How does the universe work? Our @NASARoman is poised to help us answer this question by shedding light on dark matter, the invisible glue that holds the universe together. Dark matter makes up about 27% of the universe, but we still don’t know what it is. ⬇️

One way Roman will investigate dark matter is by tracking how smaller clumps of it warp light from more distant galaxies. These “gravitational lensing” surveys will enable scientists to fill in some gaps in our understanding of dark matter. Learn more: go.nasa.gov/4hLqaUj

ALT This animation opens with a pie chart on a black background. Most of the circle is filled in with blue, labeled “68% Dark Energy.” A smaller red wedge is labeled “27% Dark Matter,” and a small yellow slice is labeled “5% Observable.” The pie chart spins and turns into a white question mark. The animation is watermarked with: “Credit: NASA's Goddard Space Flight Center.”

Zippy particles called cosmic rays travel at nearly light speed across the cosmos, and astronomers have been searching for sites where these particles get their energy. Thanks to our NuSTAR telescope, we’ve found another candidate: pulsar wind nebulae. nustar.caltech.edu/news/nust…

The Perseus galaxy cluster makes us want to cozy up with a seasonal beverage. Captured by @ChandraXray, the enormous waves of gas making this cosmic latte art likely formed billions of years ago due to the flyby of a smaller galaxy cluster. More: go.nasa.gov/4y40Dwg

ALT This simulation starts with a bright orange-yellow sphere in the center on a dark red-orange background. A wave passes through the scene, shown as an arc swiping across the image. The wave disturbs the sphere, which then breaks up into a tangle of bright yellow strings that curl around. This represents an X-ray view of hot gas at the heart of a galaxy cluster similar to the Perseus cluster. The gas swirl is brighter at the center showing that the gas is hotter, but as it spins outward the bright tendrils dim into a deeper orange showing dissipation of the gas and how it’s cooler than the center. The image is watermarked with “Simulation,” and “Credit: John ZuHone/Harvard-Smithsonian Center for Astrophysics.”

NGC 7541 is above average! 🏅 This galaxy boasts a higher-than-usual star formation rate. A bar of stars and gas that intersects its center might be the reason why! This bar likely funnels in the material and fuel needed to create and nurture new stars: go.nasa.gov/4yPgQ8r

It’s okay to be different! Omega Centauri is the largest, brightest, and most massive globular cluster in the Milky Way. But it might not even be a globular cluster. It may be the core of a dwarf galaxy captured by the Milky Way and stripped of its outer stars. #MondayMotivation
