  7. Hubble image of Arp 190, also known as UGC 2320.

    An elliptical galaxy, off the frame, to the left, is interacting with the lower spiral galaxy. A large tidal tail extends to the right. A much fainter bridge extends to the left, connecting the two galaxies. The upper spiral may be part of the system, or it may be a foreground object that only appears to overlap.

  11. The phenomenon of double reflection occurs when celestial bodies align over calm waters, creating a symmetrical visual experience through specular reflection. This image captures the Moon and Venus as they appear on the horizon, illustrating how light interaction with smooth surfaces follows the law of reflection. Observations of these planetary conjunctions provide valuable data on orbital mechanics and atmospheric scattering, serving as a reminder of the precise geometric relationships within our solar system. Understanding these optical events bridge the gap between astronomical observation and classical physics.

  13. Arp 78, also identified as NGC 772, is a remarkable spiral galaxy located approximately 100 million light-years away in the constellation Aries. Classified as a peculiar galaxy, it spans over 200,000 light-years and is significantly larger than our Milky Way. Its distinct morphology, characterized by a single prominent outer spiral arm, is likely the result of gravitational tidal interactions with its nearby satellite companion, NGC 770. Such celestial systems provide critical insights into the complex dynamics of galactic evolution and the transformative power of gravitational forces across cosmic scales. #Astronomy #Astrophysics #NASA #Arp78

  19. #TodayInHistory 1936 – Margaret Heafield Hamilton, American computer scientist, is born.

    She directed the Software Engineering Division at #MIT Instrumentation Laboratory, where she led the development of the on-board flight software for the #NASA Apollo Guidance Computer for the Apollo program.

    She coined the term "software engineering", stating, "I began to use the term 'software engineering' to distinguish it from hardware and other kinds of engineering."

    Perseids from Perseus
    * Image Credit & Copyright: Jakub Kuřák
    instagram.com/jakubkurak/

    Explanation:
    This was a good year for the Perseids meteor shower. A key reason was the Moon was absent from lighting up Earth's night sky so that more meteors were visible than usual. Where was the Moon? It was busy visiting the Sun. Near the Perseids peak, the Moon moved directly in front of the Sun and created a total solar eclipse visible from Greenland and Spain. The Perseids occur when the Earth collides with a stream of Sun-orbiting debris cast off by Comet Swift-Tuttle. Perseid meteors, although typically only the size of a sand grain, tend to be fast and bright because Swift-Tuttle's debris orbits the Sun in a direction partly opposite Earth's orbital motion. In the featured image compilation accumulated over several nights from Jizerka in the Czech Republic, the Perseids meteor streaks can be traced back to a single location on the sky -- its radiant in Perseus.

  27. If you are interested in such things: there will be a spacewalk tomorrow, Tuesday 18 August (ESA's Sophie Adenot and NASA's Anil Menon) and ESA will have a livestream directly from the ISS:

    ▶️ esa.int/Science_Exploration/Hu

    Airlock exit expected at 12:35 GMT/14:35, the stream will start earlier.

    [edit: Sorry, mistake - it's tomorrow! Originally said "today", now corrected.]

  28. 🦢 🦅 AND ANOTHER THING …

    … I imaged overnight is this mosaic. It stretches from the sagittarius star cloud at the top to Sharpless 54 (in Serpens) at the bottom.

    The in-between bit is what it was about; the nebulae birds. The one on top is the Swan (or Omega) nebula (messier 17) and the one at the bottom is the Eagle nebula (messier 16).

    Both are star forming regions, where hot young things irradiate their environment, making it glow pink.

    This mosaic is a combination of 380 x 30 second exposures, processed on the :seestar_s30:

  31. A giant made of many 📡

    These are just a few of the 66 antennas that make up the international observatory ALMA, in which ESO is a partner.

    They work together rather than as separate telescopes, allowing astronomers to study some of the coldest material in the Universe — including clouds of gas and dust where stars are born and discs where planets take shape — in great detail.
