    M16 - The Pillars of Creation - were revisited by Hubble. It had been 19 years since they were last observed by Hubble.

    The image below shows the pillars as seen in infrared light, thus allowing the obscuring dust and gas to be pierced through for a different view of M16.

    And it is very likely that M16 no longer exists, having been destroyed by a supernova 6000 years ago.

    They still appear intact because they're 7000 light years away.

    Two of Pluto’s moons, Nix and Hydra, have been found to be in a chaotic rotation.

    A person on Pluto would not see the same face of the moons night after night.

    On the other side, a person on the moons would witness each day at different lengths to the preceding day.

    Active Galaxy 3C 264 (NGC 3862)
    [​IMG]
    In this NASA Hubble Space Telescope image of the central region of the galaxy NGC 3862, an extragalactic jet of material moving at nearly the speed of light can be seen at the three o'clock position. The jet of ejected plasma is powered by energy from a supermassive black hole at the center of the elliptical galaxy, which is located 260 million light-years away in the constellation of Leo.

    A sequence of Hubble images of knots (outlined in red, green, and blue) shows them moving along the jet over a 20-year span of observing. Astronomers were surprised to discover that the central knot (green) caught up with and merged with the knot in front of it (blue). The new analysis suggests that shocks produced by collisions within the jet further accelerate particles that are confined to a narrowly focused beam of radiation. The "X" marks the location of the black hole.​

    Globular cluster 47 Tucanae
    [​IMG]
    This NASA/ESA Hubble Space Telescope image shows a globular cluster known as NGC 104 — or, more commonly, 47 Tucanae, since it is part of the constellation of Tucana (The Toucan) in the southern sky. After Omega Centauri it is the brightest globular cluster in the night sky, hosting tens of thousands of stars.

    Scientists using Hubble observed the white dwarfs in the cluster. These dying stars migrate from the crowded centre of the cluster to its outskirts. Whilst astronomers knew about this process they had never seen it in action, until the detailed study of 47 Tucanae.

    Missing the party, however, may not have been so bad. The Sun's late appearance may actually have fostered the growth of our solar system's planets. Elements heavier than hydrogen and helium were more abundant later in the star-forming boom as more massive stars ended their lives early and enriched the galaxy with material that served as the building blocks of planets and even life on Earth.

    Astronomers don't have baby pictures of our Milky Way's formative years to trace the history of stellar growth. Instead, they compiled the story from studying galaxies similar in mass to our Milky Way, found in deep surveys of the universe. The farther into the universe astronomers look, the further back in time they are seeing, because starlight from long ago is just arriving at Earth now. From those surveys, stretching back in time more than 10 billion years, researchers assembled an album of images containing nearly 2,000 snapshots of Milky Way-like galaxies.

    The new census provides the most complete picture yet of how galaxies like the Milky Way grew over the past 10 billion years into today's majestic spiral galaxies. The multi-wavelength study spans ultraviolet to far-infrared light, combining observations from NASA's Hubble and Spitzer space telescopes, the European Space Agency's Herschel Space Observatory, and ground-based telescopes, including the Magellan Baada Telescope at the Las Campanas Observatory in Chile.

    The hole that NASA's Curiosity Mars rover drilled into target rock "John Klein" provided a view into the interior of the rock, as well as obtaining a sample of powdered material from the rock. The rock is part of the Sheepbed mudstone deposit in the Yellowknife Bay area of Gale Crater. This image, taken by Curiosity's Mars Hand Lens Imager (MAHLI) camera, reveals gray colored cuttings, rock powder and interior wall. Notice the homogeneous, fine grain size of the mudstone, and the irregular network of sulfate-filled hairline fractures. A vertical array of pits in the side of the hole resulted from using the laser-shooting Chemistry and Camera (ChemCam) instrument to assess composition at those points. The MAHLI took this image during the 270th Martian day, or sol, of Curiosity's work on Mars (May 10, 2013). The diameter of hole is about 0.6 inch (1.6 centimeters).

    The Sheepbed mudstone is interpreted to represent an ancient lake. It preserves evidence of an environment that would have been suited to support microbes that get their energy by eating chemicals in rocks. This wet environment was characterized by neutral pH, low salinity, and variable oxidation of iron- and sulfur-containing minerals. Carbon, hydrogen, oxygen, sulfur, nitrogen and phosphorus were measured directly as key elements for supporting possible life. These results highlight the biological viability of fluvial-lacustrine environments (streams and lakes) in the history of Mars after the earliest era of the Martian past, called the Noachian Era.

    Because of the mass of Charon compared to Pluto, Charon doesn't actually orbit Pluto but both Pluto and Charon orbit a barycenter between them.

    Don't think we, as in you and I, will see a colony on a Earth-like planet. That includes Mars.

    The closets possible habitable planet is 13 light years away. Possible being italicized because we don't know 100% if "humans" can survive there. So, 13 light years away means traveling at the speed of light that would take us 13 years to get there.

    We are not able to travel anywhere near that fast.

    Using the technology we have today, we could catch a ride on the fastest man-made object, Voyager 1, at 38,610 mph. With 1 light year being some 5,878,625,373,184 miles, catching a ride on Voyager 1 would take about 17,380 years to get there.

    No shit, no one who is alive right now will live to see a permanent colony on another planet.

    Exoplanets are relatively new discoveries, though. Something like the top 30-35 most Earth-like planets that we know about have been discovered just within the last four years. Not that they'll be <1 ly away or anything... but there are likely some that are close, relatively speaking.

    Voyager 1 is the furthest man-made object from us, not the fastest.

    At 3:21 p.m. (EDT), NASA'S Juno Mission spacecraft will slingshot around Earth towards Jupiter, accelerating to 25 miles per second along the way and becoming the fastest man-made object in history. A .50-caliber bullet travels at about half a mile a second, by contrast -- nowhere near the blistering speed of Juno.Oct 9, 2013

    165000 miles per hour.

    I don't get how people can think we are alone. Our entire observable universe makes up 1% of the space. Even if there was super intelligent life out there it would have to be such a miniscule chance that they would find us.

    Real exciting space stuffs going down in the next two weeks. The New Horizons probe, which has been en route to Pluto for 9 years, is expected to reach its destination on July 12-14th. The last chance to send a signal to the probe to hit a 100x150 km square of space is July 4th. A lot at stake here and anything can happen. It takes 9 hours for a signal to reach the probe from Earth. Going to be insane.

    Before this, all we have are grainy satellite images of Pluto so we have no idea what it looks like or what's on the surface.

    Yeah, it wasn't time for staging, and seeing all of that vapor, you knew what just happened. The debris field about 5 seconds later confirmed it.

    That's really not good considering

    1. the other American robotic cargo spacecraft blew up on the pad not six months ago.
    2. and the russian robotic cargo spacecraft had a launch failure in April

    So much for multiple supplier redundency.

    I think I saw the vertical stabilizer thrusters firing a few seconds before it blew up and thought it looked off. Fortunately this shouldn't change their future launch schedule. I'll be curious to see what actually went wrong.
