Deep Space

  • Before the Beginning
    Astronomer Royal, Sir Martin Rees discusses the limits to our knowledge of what might have preceded the big bang. Everyone asks the question: what was 'there' the instant before everything came to be?, but the question may not go as deep as the answers it

  • New Worlds, Living Large
    Counting down the top ten astrobiology stories for 2004 highlights the accomplishments of those exploring Mars, Saturn, comets, and planets beyond Pluto. Number three in this countdown was the remarkable progress in discovering new planets in other solar systems.

  • Not So Nebulous
    For the first time, a team of astronomers based in Germany has detected the presence of magnetic fields in the central stars of four planetary nebulae. Planetary nebulae are expanding gas shells that remain after Sun-like stars eject their outer layers at the end of

  • Our Cosmic Patch
    Astronomer Royal, Sir Martin Rees talks to Astrobiology Magazine about the conditions for life. How unique is our world? Is the universe itself just the byproduct of many failed, sterile or stillborn universes that might have preceded it?

  • Venus: Sizing Up the Solar System
    Counting down the top ten astrobiology stories for 2004 highlights the accomplishments of those exploring Mars, Saturn, comets, and planets beyond Pluto. Number nine in this countdown was the rarest of all eclipses, the once-per-century eclipse of the Sun by Venus.

  • Antimatter over Antarctica?
    An international team of researchers will fly a balloon and sensitive detectors over the South Pole. They won't be searching for anything known in our universe of matter. They will seek out remnants of antimatter.

  • Decoding Dusty Disks
    Looking at sun-like stars known to harbor planets, the Spitzer Space Telescope has found evidence of dusty rings similar to the Kuiper Belt in our own solar system. Beautiful new images from Hubble show how such systems might appear, looking from the outside in.

  • Bring in the Clouds
    The Tarantula Nebula is a stunning example of turbulent mixing--an energetic display of dust and voids that gives this region of the southern sky its spider-like legs. These filaments span nearly its entire thousand light-year width.

  • Planet Swapping
    Could a passing star exchange planets with our own Sun? Computer simulations suggest that a glancing blow might contribute far outer planets following star disk collisions.

  • Earthlings’ Low Signal-to-Noise?
    Our most efficient attempts to broadcast our planet's existence to another civilization would resemble the thermal radiation emitted by stars. By analogy, more advanced worlds would likely do the same, making our chances of listening in hard to distinguish from hearing stellar noise.

  • The Search for Ourselves in the Cosmos
    Our senses alone offer only a narrow window on the physical universe, as Neil deGrasse Tyson writes in his four-part NOVA/PBS series, "Origins". The tour de force looks at how we measure our place in the universe based on the part of the universe

  • Dust to Rocky Planets
    New observations reveal how pristine, primordial dust aggregates to form rocky planets around other stars. One question astronomers would like to answer is how common such Earth-like planets are and whether solar system formation proceeds routinely around other stars.

  • The Origin of Life on Earth
    Neil deGrasse Tyson, author and host of the NOVA series, "Origins, Fourteen Billion Years of Cosmic Evolution", gives a galvanizing tour of the cosmos revealing what the universe has been up to while turning part of itself into us.

  • Advancing the Webb
    The Webb Space Telescope is one of the next generations observatories that will reside near the balance point (L2) between the Earth and Sun.

  • SWIFT to Unravel Energetic Flashes
    When the SWIFT detector looks at the sky using its gamma-ray sensitive view, the chance to unravel the cause of the most energetic stellar events may become possible.
