    No way we're alone. With one to two trillion galaxies in the observable universe containing 700 sextillion stars (7 with 23 zero's behind it), each with numerous planets around them, the odds of us being alone simply don't add up.

    One of the most important advances in (ground based) optical telescope design over the past few decades was the introduction of adaptive optics. The system continually corrects for distortion in the image by analyzing the image in near realtime, and applying an inverse distortion through moveable (warpable) mirrors.

    The Heart and Soul Nebulas, IC 1805 and IC 1871, are located in Cassiopeia. Several young open star clusters are visible near their centers. The two are ~6,000 light years away, and are ~300 light years across. The yellow light is emitted by sulfer, red by hydrogen, and blue by oxygen.

    NASA's OSIRIS-REx probe captured this photo of Earth and the Moon (lower left) while snapping a pic of the asteroid Bennu (right) on December 19, 2018. The probe is orbiting at ~27 miles above Bennu, and is ~71 million miles from Earth.

    The Hidden Galaxy (IC 342). This nearly neighbor is only 10 million light-years from the Milky Way.

    M102, the Spindle galaxy, provides a unique edge-on view. It's located ~50 million light-years away.

    Ultima and Thule. On January 1st, the New Horizons probe encountered the Kuiper Belt object Ultimate Thule at a distance of 6.5 billion km from the sun, the most distant object every visited by a spacecraft. The image revealed that the object was a binary contact, or two spherical objects held together by mutual gravity. The larger object, Ultima, is ~19 km in diameter. The smaller object, Thule, is ~14 km in diameter.

    A better image was released a few days ago.

    A streak of mostly hydrogen extends ~200,000 light-years from spiral galaxy D100. The tail contains ~400,000 times the mass of our sun. As the galaxy passes through the gas cloud in the surrounding Coma Cluster, the outer gas is stripped away, leaving the narrow central tail.

    The latest photos of the asteroid Bennu taken by the OSIRIS-REx spacecraft are quite detailed.

    A cosmic bubble, Sharpless 2-308, lies ~5,200 light years away. The nebula is ~60 light-years wide, and is estimated to be ~70,000 years old.

    The spiral galaxy pair NGC 4567 and NGC 4568, also known as the Butterfly galaxies. The elliptical galaxy NGC 4564 is to the right. The pair are located ~52 million light-years away.

    LDN 1622: The Dark Nebula in Orion (aka The Boogeyman Nebula). The dark nebula, an interstellar cloud of dust particles coated with frozen carbon monoxide and nitrogen that is so dense that it blocks the light from the objects behind it, sits ~500 light-years away.

    The Milky Way is generally thought to be a flat, spiral galaxy. However, a recent mapping of 1,339 Cepheid variable stars, a type of pulsating star whose distance can be accurately measured, shows our galaxy warping at the edges. The mapping was produced by a joint team from the Macquarie University in Australia, and the Chinese Academy of Sciences.

    The doomed star Eta Carinae.



    Eta Carinae is ~100 times more massive than the Sun, which means it will very likely end its life in a supernova in the very near future. It will leave behind a black hole. 'Can't wait.

    A very nice edge-on view of spiral galaxy NGC 4565, the Needle Galaxy. The galaxy is ~100,000 light-years wide, roughly the same as our Milky Way, and lies ~40 million light-years away.

    NGC 2359, Thor's Helmet. The central star in this cosmic cloud is an extremely hot giant believed to be in a per-supernova stage that is basically blowing a hot bubble within the molecular cloud. The helmet is located ~15,000 light-years away, and is ~30 light-years across.

    NGC 72293, The Helix Nebula, a planetary nebula located 690 light years away. The star at the center of the nebula is similar to our Sun. At the end of its life it begins to expand, and sheds its outer layers. The star will become a white dwarf.

    The Butterfly Nebula (NGC 6302). The "wings" are jets of heated gas (36,000 degrees F) traveling at more than 600,000 miles an hour. The wingspan is over 3 light-years. At the center is a dying star that was once ~5 times the mass of our Sun. The nebula is ~3800 light years away.

    SpaceX's Crew Dragon capsule made a successful splashdown in the Atlantic Ocean today. The unmanned capsule was launched aboard a Falcon 9 rocket on March 2, and docked with the ISS a day later. The ISS crew resealed the capsule yesterday, and it undocked from the station at 2:32 am ET this morning. 'Just over 6 hours later it splashed down at the scheduled time.

    The central magnetic field of the Cigar Galaxy, M82, taken by the HAWC+ instrument onboard the airborne SOFIA observatory. The magnetic lines have been overlaid on top of optical light (gray), hydrogen gas (red), and infrared (yellow). The galaxy is ~12 million light-years away.
