    NGC 2070, The Tarantula Nebula, is 1000 light-years in diameter, and lies inside our satellite galaxy the Large Magellanic Cloud. It's ~180,000 light-years away. If the nebula was as close as the Orion Nebula, it would take up half the night sky.

    The first photo from NASA's InSight lander on the surface of Mars. The horizon is on the upper 1/4 of the photo, and the fisheye camera lens is obviously covered in dust kicked up during the landing.


    A little better.

    You know what I would REALLY like to see? Video of the lander's approach/descent. There is a great video on YouTube of a shuttle launch with cameras hooked to the SRBs, and it shows the separation and descent back into the ocean. It's awesome.

    IC 1871, the Soul Nebula, is ~25 light-years across, and ~6,500 light-years from Earth.

    NASA's OSIRIS-REx spacecraft arrived at the asteroid Bennu today. Launched in September 2016, the spacecraft will eventually take a ~2 kg sample of the asteroid, and return it to Earth. It's currently in a 7 km high orbit around the asteroid, which itself is quite a feat given the low gravity environment of this 1600 ft wide hunk of rock and metal.

    ESA astronaut Alexander Gerst snapped this photo from the International Space Station of today's launch of a Soyuz rocket. The rocket carries three new crew members to the ISS.

    I can never get bored looking at pics of the Andromeda galaxy. Andromeda (M31) is located 2.5 million light-years from Earth, and is our nearest spiral galaxy neighbor.

    A digital stack of 240 images taken over a period of 1.5 hours from the Everest Base Camp captures the north face of the mountain, and the colorful star trails. Blueish trails are hotter stars, and yellow/red trails are stars cooler than the Sun.

    Phobos, one of Mars' twin moons. It's only 25 km across, and orbits at ~5,800 km, compared to 400,000 km for out Moon. Phobos is believed to be a captured asteroid. It's so close that it's being dragged down by tidal forces, and will break up in orbit and crash down on to the Martian surface in ~50 million years.

    On this day twenty years ago space shuttle Mission STS-88 connected the Unity node to the Russian Zarya module, marking the start of construction of the International Space Station. My how time flies.

    The large spiral galaxy NGC 1055 (top left), and the spiral galaxy M77 (bottom right). Both are 100,000 light-years across, and members of a galaxy group ~60 million light-years away. The two are ~500,000 light years apart, or 20% of the distance from the Milky Way to our nearest galactic neighbor Andromeda. The image, taken on November 28th, contains a clear view of the newly discovered supernova SN2018ivc in an arm of M77.

    NGC 281, the Pacman Nebula, is located ~10,000 light years away. The pic covers an area ~80 light-years across.

    Spiral galaxy Arp 188, the Tadpole Galaxy, located 420 million light-years away, features a 280,000 light-year long tail. It's believed that a compact galaxy crossed in front of the Tadpole (from right to left), and the tidal forces drew out the galaxy's stars, gas, and dust.

    A nebula surrounds the binary star system R Aquarii. Located 700 light-years away, the pair consist of a red giant star that is losing material to its companion star, a hot white dwarf.

    M100 is known as a grand design spiral galaxy. It's home to over 100 billion stars. It's located 56 million light-years away.

    The Triangulum Galaxy (M33 or NGC 598) is part of the "Local Group," the same group of galaxies that contains Andromeda and the Milky Way. It's the third-largest galaxy in the group at 60,000 light-years across. By comparison, the Andromeda Galaxy is 200,000 light-years across and the Milky Way is 100,000 light-years in diameter. The image spans roughly 19,000 light-years, and is estimated to contain between 10 and 15 million stars.

    The Vela Supernova Remnent, the expanding debris cloud from a star that exploded ~11,000 years ago, is located 800 light-years from Earth. At its heart is the Vela Pulsar, a neutron star that spins ten times a second. It is more massive than the Sun, but has a diameter of ~12 miles.

    There is an interesting TED talk that I watched the other day by astronomer Stephen Webb (Where Are All The Aliens?) who argues that we are alone in this universe. But in looking at these photos, you have to could that possibly be?


    What if we ARE alone?
