Right #now Chandra is peeping at what's steeping in the "Teacup," more than a billion light years from Earth! This galactic #storm has been raging for thousands of years, a #space tempest powered by a type of actively growing #BlackHole known as a quasar! ☕️ Want to know more about #science behind the #pic ? http://chandra.harvard.edu/instagram/
#Today Chandra is gazing at #galaxy NGC 2276 in Cepheus! 🌀 This unusually shaped spiral galaxy is located about 100 million light years from Earth and it contains an intermediate-mass #BlackHole (IMBH ) about 50,000 times the mass of our Sun! ⚫️🌞 Want to know more about the #science behind the #pretty #pic ? http://chandra.harvard.edu/instagram/
Right #now Chandra is studying a star ⭐️ in Vulpecula! Nearby in the sky is the M27, commonly known as the #Apple Core or Dumbbell Nebula. This planetary nebula is located about 1,200 light years from Earth and is so bright it can be seen with binoculars in #dark sky conditions! #Space #Science is #Beautiful !
Right #now Chandra is studying a cluster of #stars in Crux! ✨ Nearby in the sky is the Coalsack, a #dark nebula about 35 light years across, a portion of which can be seen in this image. Dark nebulae are interstellar clouds so thick with dust that they block visible light emitted from the objects behind them! #Science #Learning #STEM #Education
#News : Scientists have uncovered a #BlackHole that may have sparked the birth of #stars across multiple galaxies and over a phenomenal distance of more than a million light years — the largest distance ever detected! ⚫️ More in the comments!

Supernova remnants form when a massive #star explodes and its remains are hurled outward into #space . On average, this occurs 2 times per century in our Milky Way galaxy! 💥 💥 This #supernova remnant, G352, is about 24,000 light years from Earth and roughly 1,000 light years across!

About 250 light years across, 3C 397 is a supernova remnant with an unusual shape! Its box-like appearance was likely produced as the heated remains of an exploded #star ran into the cooler gas surrounding it. This boxy but good remnant is located roughly 33,000 light years from Earth in the constellation Aquila. #explore #extreme #space !
⭐️Right #now Chandra is studying a #star in Carina. Nearby in the sky is the #famous Bullet Cluster! Located about 3.8 billion light years from Earth, the cluster was formed after the violent collision of 2 large clusters of galaxies. 💥💥 The Bullet Cluster has become a #popular object for astrophysical research, including studies of #DarkMatter and the dynamics of million-degree gas!

🌀🌀 These 2 merging galaxies have hosted at least 3 #supernova explosions in the last 20 years! Located about 130 million light years from Earth, galaxies NGC 2207 and IC 2163 are forming #stars of various masses at a rate equivalent to 24 stars the mass of our Sun per year!

🔭 Right #now Chandra is gazing at galaxy Maffei 1, located ~10 million light years from #Earth in #space . Also seen in this image is part of the large star-forming nebula IC 1805. The #nebula is much closer to us than the #galaxy , it's only about 6,000 light years away! #Today 's Observation #Time : 8 hours 3 minutes #Science #pics #wow
⭐️ A planetary nebula is formed during a late stage in the evolution of a Sun-like #star . The evolution of Abell 30 stalled and then started up again, producing a smaller nebula inside the original! Planetary nebulae actually have nothing to do with #planets . The term is simply a #historic relic since these objects looked like planetary disks to astronomers in earlier times looking through small optical telescopes! The #science behind the #pic : After having steadily produced energy for several billion years through the nuclear #fusion of hydrogen into helium in its central region, or core, the star undergoes a series of energy crises related to the depletion of hydrogen and subsequent contraction of the core. These crises culminate in the star expanding a hundred-fold to become a red giant. Eventually the outer envelope of the red giant is ejected and moves away from the star at a relatively sedate #speed of less than 100,000 miles per hour. The star meanwhile is transformed from a cool giant into a hot, compact star that produces intense ultraviolet (UV ) radiation and a fast wind of particles moving at about 6 million miles per hour. The interaction of the UV radiation and the fast wind with the ejected red giant envelope creates the planetary nebula, shown by the large spherical shell in the image. In rare cases, nuclear fusion reactions in the region surrounding the star's core heat the outer envelope of the star so much that it temporarily becomes a red giant again. The sequence of events — envelope ejection followed by a fast stellar wind — is repeated on a much faster scale than before, and a small-scale planetary nebula is created inside the original one. In a sense, the planetary nebula is #reborn ! #beautiful #space
Right #now Chandra is examining stars in the #Jewel Box! The Jewel Box cluster, also known as NGC 4755, is located about 6,400 light years from Earth in #space . The cluster sparkles with the light of just over 100 stars, including many #sapphire -blue stars and a #ruby -red supergiant! #Science is #Beautiful !
Right #now Chandra is gazing at a #galaxy cluster in Horologium! Nearby in the sky 2 galaxies are merging, a process that began millions of years ago. About 30 million light years from Earth, the smaller galaxy, NGC 1510, will one day become part of the larger galaxy, NGC 1512. #Today in #space #science
A light year is a unit of distance. It is the distance that light can travel in one Earth year (~365 days ). Light moves at a velocity of about 300,000 kilometers (186,411 miles ) each second. So in one year, it can travel about 10 trillion kilometers (6 trillion miles ). If you could travel at the speed of light, you could go around the Earth 7.5 times in one second! #NationalSTEMDay
Right #now Chandra is gazing at galaxies in Boötes! 🌀Nearby in the sky are 4 galaxies known collectively as Arp 297.
