Galaxy M101 contains hundreds of billions of stars! About 22 million light years away, it's nearly twice as wide as our Milky Way. It would take a beam of light more than 170,000 years to get from one side of the galaxy to the other! More: https://t.co/7uS0zCXkGa#beautiful
Right #now Chandra is investigating a black hole at least 300 million times the mass of our Sun! The black hole resides about 55 million light years from Earth in galaxy M84, one of over 1,000 galaxies that make up the Virgo Cluster. More: https://t.co/BW9qYO74AD#science
@Prashant13w @NASAspitzerYes! Due to the star's motion, a bow shock is being created ahead of the star’s direction of travel. It’s similar to the ripples that precede the bow of a ship as it moves through the water, or the sonic boom of an airplane hitting supersonic speeds! ✨
Right #now Chandra is studying a galaxy in Ophiuchus. Nearby in the sky is Zeta Ophiuchi, a blue star 80,000 times brighter than our Sun that's zipping through #space at roughly 24 km per second! It's likely that a companion star exploded as a supernova, giving Zeta Oph a push!
Right #now Chandra is studying the interactions of a group of galaxies known as HCG 57! The large spiral galaxy on the right-hand side of this image (NGC 3746) has hosted at least two recent supernova explosions, one observed in 2002 and another in seen 2005! #Today's Ob: 6h 23m
Right #now Chandra is gazing at a galaxy in Ursa Major! Nearby in the sky is this #beautiful object, the Owl Nebula. A planetary nebula roughly 2 light years across, it's nested just below the bowl of the Big Dipper about 2,600 light years from Earth! #Today's Obs: 6h 56m
#News : Scientists have spent years looking for something that sounds like it would be hard to miss: about a third of the "normal" matter in the Universe. According to a new study using Chandra, the Universe's "missing mass" may have been found!https://t.co/dnrfVMI9D6
Investigating the Universe is best done in many wavelengths of light! Check out these radio telescope #space images in honor of #WorldRadioDay! Hercules A (blue), Tycho's Supernova Remnant (pink), and the Crab Nebula (red).
Right now Chandra is gathering information about a flare star in Andromeda! The target, GJ15A, is host star to at least 1 rocky exoplanet. Data like these will be used to assist future #science, allowing us to better understand the atmospheres of planets outside our solar system.
This cat-shaped image is actually the remains of 2 exploded stars! Roughly 160,000 light years from Earth in the Large Magellanic Cloud, this chance alignment of supernova remnants is pawsitively purrfect on #NationalCatDay! https://t.co/PP4Fw8u3ya
#DYK there's a supermassive black hole at the center of our galaxy called Sagittarius A*? It's about 26,000 light years from Earth and 4.5 million times the mass of our Sun! Here it is flaring up after a possibly devouring an asteroid! https://t.co/hJFCI8XE7I#BlackHoleFriday
