The History of Astronomy

  • Astronomy

    Astronomy
    Astronomy, a natural science, is the study of celestial objects (such as stars, galaxies, planets, moons, asteroids, comets and nebulae) and processes (such as supernovae explosions, gamma ray bursts, and cosmic microwave background radiation), the physics, chemistry, and evolution of such objects and processes, and more generally all phenomena that originate outside the atmosphere of Earth.
  • International Astronomy Day

    International Astronomy Day
    Astronomy Day is an annual event intended to provide a means of interaction between the general public and various astronomy enthusiasts, groups and professionals. The theme of Astronomy Day is "Bringing Astronomy to the People," and on this day astronomy and stargazing clubs and other organizations around the world will plan special events.
  • Draconids Meteor Shower.

    Draconids Meteor Shower.
    The Draconids is a minor meteor shower producing only about 10 meteors per hour. It is produced by dust grains left behind by comet 21P Giacobini-Zinner, which was first discovered in 1900. The Draconids is an unusual shower in that the best viewing is in the early evening instead of early morning like most other showers.
  • June Solstice.

    June Solstice.
    The June solstice occurs at 22:34 UTC. The North Pole of the earth will be tilted toward the Sun, which will have reached its northernmost position in the sky and will be directly over the Tropic of Cancer at 23.44 degrees north latitude.
  • Supermoon.

    Supermoon.
    The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This phase occurs at 13:52 UTC. This full moon was known by early Native American tribes as the Full Beaver Moon because this was the time of year to set the beaver traps before the swamps and rivers froze.
  • Juno at Jupiter.

    Juno at Jupiter.
    NASA’s Juno spacecraft is scheduled to arrive at Jupiter after a five year journey. Launched on August 5, 2011, Juno will be inserted into a polar orbit around the giant planet on or around July 4, 2016. From this orbit the spacecraft will study Jupiter’s atmosphere and magnetic field.
  • Ursids Meteor Shower.

    Ursids Meteor Shower.
    The Ursids is a minor meteor shower producing about 5-10 meteors per hour. It is produced by dust grains left behind by comet Tuttle, which was first discovered in 1790. The shower runs annually from December 17-25.
  • Conjunction of Venus and Jupiter.

    Conjunction of Venus and Jupiter.
    A spectacular conjunction of Venus and Jupiter will be visible in the evening sky. The two bright planets will be extremely close, appearing only 0.06 degrees apart. Look for this impressive pairing in the western sky just after sunset.
  • Lyrids Meteor Shower.

    Lyrids Meteor Shower.
    The shower runs annually from April 16-25. It peaks this year on the night of the night of the 21st and morning of the 22nd. These meteors can sometimes produce bright dust trails that last for several seconds. Unfortunately this year the glare from the full moon will block out all but the brightest meteors.
  • Full Moon

     Full Moon
    The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This phase occurs at 01:46 UTC. This full moon was known by early Native American tribes as the Full Wolf Moon because this was the time of year when hungry wolf packs howled outside their camps.
  • Quadrantids Meteor Shower

    Quadrantids Meteor Shower
    The Quadrantids is an above average shower, with up to 40 meteors per hour at its peak. It is thought to be produced by dust grains left behind by an extinct comet known as 2003 EH1, which was discovered in 2003. The shower runs annually from January 1-5. It peaks this year on the night of the 3rd and morning of the 4th.
  • Total Solar Eclipse

    Total Solar Eclipse
    A total solar eclipse occurs when the moon completely blocks the Sun, revealing the Sun's beautiful outer atmosphere known as the corona. The path of totality will only be visible in parts of central Indonesia and the Pacific Ocean.
  • New Moon.

     New Moon.
    The Moon will located on the same side of the Earth as the Sun and will not be visible in the night sky. This phase occurs at 01:30 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.
  • Blue Moon.

     Blue Moon.
    The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This phase occurs at 21:15 UTC. This full moon was known by early Native American tribes as the Full Flower Moon because this was the time of year when spring flowers appeared in abundance.
  • Penumbral Lunar Eclipse.

    Penumbral Lunar Eclipse.
    A penumbral lunar eclipse occurs when the Moon passes through the Earth's partial shadow, or penumbra. During this type of eclipse the Moon will darken slightly but not completely. The eclipse will be visible throughout most of extreme eastern Asia, eastern Australia, the Pacific Ocean, and the west coast of North America including Alaska.
