  • Not Just Sitting Ducks. Maybe Satellites Could Dodge Almost all Space Junk
    by Andy Tomaswick on October 15, 2021 at 8:15 pm

    Kessler syndrome is becoming more and more of a potential hazard as more and more companies vie to place more and more satellites in Low Earth Orbit (LEO).  But it will only get out of hand if a chain reaction of collisions happens, which could potentially cause a complete breakdown of orbital infrastructure.   To combat … Continue reading “Not Just Sitting Ducks.

  • NASA’s Mission to Visit 8 Asteroids, Lucy, Launches on October 16th
    by Nancy Atkinson on October 15, 2021 at 2:49 pm

    An early morning launch is planned for the Lucy spacecraft, the first space mission to study Jupiter’s Trojan asteroids. Tomorrow, October 16 at 5:34 a.m. EDT is the first day and time in Lucy’s 21-day launch window, and current weather conditions show a 90% chance of favorable conditions for liftoff from Cape Canaveral Space Force … Continue reading “NASA’s Mission to Visit 8 Asteroids, Lucy, Launches on October 16th” The post NASA’s Mission to Visit 8 Asteroids, Lucy, Launches on October 16th appeared first on Universe Today.

  • Why Visit Just one Moon When you Could Explore Them all?
    by Evan Gough on October 14, 2021 at 7:54 pm

    The Solar System’s moons are intriguing objects for exploration. Especially moons like Europa and Enceladus. Their subsurface oceans make them primary targets in the search for life. But why not send one spacecraft to visit several moons? NASA’s about to launch its Lucy mission which will visit 8 separate asteroids. Could the same be done … Continue reading “Why Visit Just one Moon When you Could Explore Them all?” The post Why Visit Just one Moon When you Could Explore Them all? appeared first on Universe Today.

  • The Biggest Comet Ever Seen Will get as Close as Saturn in 2031
    by Nancy Atkinson on October 14, 2021 at 7:10 pm

    A mega-comet – potentially the largest ever discovered – is heading from the Oort Cloud towards our direction. Estimated to be 100–200 kilometers across, the unusual celestial wanderer will make its closest approach to the Sun in 2031. However, the closest it will come to Earth is to the orbit of Saturn. Astronomers say Comet … Continue reading “The Biggest Comet Ever Seen Will get as Close as Saturn in 2031” The post The Biggest Comet Ever Seen Will get as Close as Saturn in 2031 appeared first on Universe Today.

  • China’s FAST Telescope Could Detect Self-Replicating Alien Probes
    by Andy Tomaswick on October 14, 2021 at 5:18 pm

    One of the most challenging questions to answer when confronting the Fermi Paradox is why exponentially scaling technologies haven’t taken over the universe by now.  Commonly known as von Neumann probes, the idea of a self-replicating swarm of extraterrestrial robots has been a staple of science fiction for decades.  But so far, there has never … Continue reading “China’s FAST Telescope Could Detect Self-Replicating Alien Probes” The post China’s FAST Telescope Could Detect Self-Replicating Alien Probes appeared first on Universe Today.

  • Advanced Civilizations Could use Their Stars to Communicate (and as Telescopes)
    by Matthew Cimone on October 14, 2021 at 2:46 pm

    A Long Distance Call E.T. managed to call home with a Speak and Spell, buzzsaw blade, and an umbrella. The reality of interstellar communication is a bit more complicated. Space is really, really big. The power needed to transmit a signal across the void is huge. However, rather than using super high power transmitters, recent … Continue reading “Advanced Civilizations Could use Their Stars to Communicate (and as Telescopes)” The post Advanced Civilizations Could use Their Stars to Communicate (and as Telescopes) appeared first on Universe Today.

  • Images of 42 of the Biggest Asteroids in the Solar System
    by Nancy Atkinson on October 13, 2021 at 9:15 pm

    A huge team of astronomers have combined forces to use the European Southern Observatory’s Very Large Telescope (ESO’s VLT) to provide the sharpest view ever of 42 of the largest objects in the asteroid belt, located between Mars and Jupiter. Fittingly, the collection of images was released on the 42nd anniversary of the publication of … Continue reading “Images of 42 of the Biggest Asteroids in the Solar System” The post Images of 42 of the Biggest Asteroids in the Solar System appeared first on Universe Today.

  • You Can Blow Up an Asteroid Just a few Months Before it Hits Earth and Prevent 99% of the Damage
    by Evan Gough on October 13, 2021 at 7:01 pm

    So far, the battle between life on Earth and asteroids has been completely one-sided. But not for long. Soon, we’ll have the capability to deter asteroids from undesirable encounters with Earth. And while conventional thinking has said that the further away the better when it comes to intercepting one, we can’t assume we’ll always have … Continue reading “You Can Blow Up an Asteroid Just a few Months Before it Hits Earth and Prevent 99% of the Damage” The post You Can Blow Up an Asteroid Just a few Months Before it Hits Earth and Prevent 99% of the Damage appeared first on Universe Today.
