LA FISICA A PUZZLE: Il segnale gravitazionale corrispondente alla collisione di due stelle di neutroni, denominato GW170817, è stato registrato il 17 agosto alle 14:41, ora italiana. La rivelazione è stata fatta dai due rivelatori gemelli LIGO, situati l’uno a Hanford, nello stato di Washington e l’altro a Livingston, in Louisiana. Le informazioni fornite dal terzo rivelatore, VIRGO, situato in Italia, vicino a Pisa, hanno permesso la precisa localizzazione dell’evento cosmico. #gravityandlight #gravitationalwaves #neutronstars #collision #detection #ligo #virgo #universe #physics #science #research Illustrazione: Luca Ralli ©INFN

"... and that is how you were born son" 😂 TAG YOUR NEWLY WED FRIENDS. By @nasa - Round and round they go - then BOOM! This animation begins with the final moments of two neutron stars (the super-dense cores of exploded massive stars), whirling around each other in a galaxy 130 million light-years away. Gravitational waves (rippling disturbance in space-time, shown here as pale arcs) bleed away orbital energy, causing the stars to move closer together and merge. As the stars collide, this explosive event emits light across a series of different wavelengths - first gamma rays (magenta), then ultraviolet (violet), then visible and infrared (blue-white to red) and once the jet directed toward us expanded into our view from Earth, X-rays (blue). Our Fermi Gamma-Ray Space Telescope witnessed this event on August 17, 2017 and we watched it unfold over multiple days with a variety of other telescopes, including the Swift spacecraft, the Hubble Space Telescope ( @NASAHubble), the Spitzer Space Telescope, our Chandra X-Ray Observatory ( @NASAChandraXray) and our NuSTAR mission. The detectors at the Laser Interferometer Gravitational-Wave Observatory (LIGO) received a gravitational wave signal just 1.7 seconds before the first light was seen by Fermi, making this the first event observed in both light and gravitational waves.

LA FISICA A PUZZLE: Il 17 agosto 2017, per la prima volta nella storia dell’osservazione dell’Universo, è stata rivelata un’onda gravitazionale prodotta dalla fusione di due stelle di neutroni e captata, dalle onde radio fino ai raggi gamma, la radiazione elettromagnetica associata alla poderosa esplosione avvenuta durante il fenomeno. È la prima volta che un evento cosmico viene osservato sia nelle onde gravitazionali che elettromagnetiche, avviando così l’era dell’astronomia multimessaggero, che estende notevolmente il nostro modo di “vedere” e “ascoltare” il cosmo. #gravityandlight #gravitationalwaves #universe #neutronstars #collision #physics #science #research #multimessenger #astronomy Illustrazione: Luca Ralli ©INFN

Now all we need is to warp spacetime to take the 2 minutes shortcut to Kepler-186F instead of travelling for 500 light years! Impossible? I believe it is possible and hopefully we will witness it happening before our demise. What do you think? 💫 This planet is named Kepler-186f and it is one of five planets that have thus far been detected by NASA’s Kepler space telescope in orbit about the star Kepler-186. This star is smaller and cooler than the Sun, of a type called an M-dwarf or red dwarf, and all its known planets are small as well, with sizes less than 1.5 times the size of Earth. The planet Kepler-186f is the smallest, being within 10% of the size of Earth and orbits furthest from the host star, within the habitable zone. This is the region around a star within which a planet can sustain liquid water on its surface given the right atmospheric conditions. The Kepler-186 planetary system lies in the direction of the constellation Cygnus, about 500 light-years away #nasa #jpl #science #space #astronomy #physics #interstellar #education #universe #multiverse #galaxies #pulsars #kepler #exoplanets #kepler186F #neutronstars #supernova #stars #milkyway #cosmos #nebulas #ScienceOfTheUniverse Image Credit: NASA

Young stars themselves are clearing out their nursery in NGC 7822. Within the nebula, bright edges and complex dust sculptures dominate this detailed skyscape taken in infrared light by NASA's Wide Field Infrared Survey Explorer (WISE) satellite. NGC 7822 lies at the edge of a giant molecular cloud toward the northern constellation Cepheus, a glowing star forming region that lies about 3,000 light-years away. The atomic emission of light by the nebula's gas is powered by energetic radiation from the hot stars, whose powerful winds and light also sculpt and erode the denser pillar shapes. Stars could still be forming inside the pillars by gravitational collapse, but as the pillars are eroded away, any forming stars will ultimately be cut off from their reservoir of star stuff. This field spans around 40 light years at the estimated distance of NGC 7822. . . . . . . . . #space #galaxy #cosmos #universe #milkywaygalaxy #amazinguniverse #amazingcosmos #amazingspace #deepspace #neutronstars #neutron #stars #spacephotography #extremephotography #nasa #natgeospace #tipoftheday #stardust #picoftheday #astronomy #astropic #astroimage #astrophoto #spacepic #spaceimage #spacephoto #spacelover #astrolover #wise #infrared
All H-Alpha for the Helix nebula, 36 h total exposure time (Single subframe exposure time between 90 sec unbinned for the center structures and 180 sec 2x2 bin for the faint environmental veils) with Hyperstar 14"/F1.9 with ASI 1600 and RASA 11"/F2.2 with ATIK 460, parallel mounted on a ASA DDM85. I am very happy how many structures of the environment are getting visible.
