⚫ A stellar-mass #BlackHole had a #powerful outburst in galaxy M83. In the span of a decade, X-ray brightness increased by at least 3,000 times! This sudden brightening is one of the largest changes in X-rays ever seen for this type of object!

🥧 It's #NationalPieDay , so why not sit back and relax with a Universe-sized slice of pie chart! This #pie shows the average abundance by mass of the various elements in the #Universe , called the cosmic abundances. The large abundance of hydrogen and helium and the small abundances of all the rest of the elements (about 2% of the total ), as well as evidence from other observations, indicate that the Universe was once composed of just one element, hydrogen, and that the nuclear fusion reactions that produce the heavier elements have proceeded very slowly over the 13.7 billion year history of the Universe. This is a good thing, since otherwise the Sun would have likely burned out long ago.! 👩🔬 Dig into the #chemistry of the Universe: https://chandra.si.edu/chemistry/ (Can you believe we got through this whole post without making a single "pie in the sky" reference? 😎 )
🌀 #Today Chandra is gazing at a #galaxy cluster in the #Phoenix constellation! Nearby in the sky is Robert's Quartet, a compact group of 4 galaxies. Huddled into a #space less than 160,000 light years across, these cosmic companions interact with each other and have produced hundreds of star-forming regions!
Right #now Chandra is studying a #galaxy in Ursa Major! Nearby in the sky is the remarkable result of a rendezvous between two galaxies known as Mayall's Object or Arp 148.

This spiral #galaxy is located roughly 100 million light years from Earth and is about 38,000 light years across — less than half the size of our Milky Way. Check out all of those other galaxies in the background! 😲 #Whoa #space #science
🦄✨ #Today Chandra is studying a #star in Monoceros, the #unicorn ! Nearby in the sky is a region of #space , known as NGC 2264, that contains a group of newborn #stars called the #Snowflake Cluster! ❄️ About 2,700 light years from Earth, the stars will begin to drift apart as they age & evolve.

Located about 3,000 light years from Earth, NGC 7027 is one of the brightest planetary nebulas in the #night sky! While #science shows it's actually somewhat of a small nebula, this bubble of multimillion degree gas still spans a distance of about 13,000 times that of Earth to the Sun! #Space is #huge !
Thousands of years ago a neutron star was formed and flung through #space by a powerful supernova explosion. By comparing observations over time, it's estimated that this cosmic cannonball continues to travel at over 4.8 million kilometers per hour — one of the #fastest moving #stars ever detected!

#Today Chandra is studying a #star ⭐️ in the Grus constellation! Nearby in the sky is the Spare Tire Nebula, IC 5148. One of the fastest growing planetary nebulas known, it's about 3 light years across and it's expanding in #space at more than 50 kilometers per second! #Astronomy #Science #Beautiful #Fast !
#Today Chandra is peering into the heart of the #Orion Nebula at the Trapezium. Located about 1,500 light years from Earth, the Trapezium is the cluster of #hot , young, luminous #stars responsible for illuminating much of the surrounding nebula. This image is a composite of infrared, ultraviolet, and visible light as observed by #NASA 's Spitzer and #Hubble #Space Telescopes.
Although there are no seasons in #space , this cosmic vista invokes thoughts of a frosty #winter #landscape . Located about 5,500 light years from Earth, NGC 6357 is a region where radiation from #hot , young stars is energizing the cooler gas in the cloud that surrounds them.
