  • 795-Spiral Comet

    3 MAY. 2024 · Comet 12P/Pons-Brooks comes near the Sun once every 71 years.  It was discovered in 1812 by Jean Louis Pons at Marseilles, France and then rediscovered by American Astronomer William Robert Brooks in 1883. Electronic cameras reveal this comet's nucleus has jets of gas that produce a spiral structure not unlike water jets from a lawn sprinkler.

  • 282E-296-Tilted History

    30 ABR. 2024 · Seasons are created by the fact that the Earth's axis of rotation is currently tilted 23 1/2 degrees relative to our path around the Sun. The slight out of roundness of the Earth's orbit combined with a 41,000 year cycle in its 3 degree axis of rotation wobble can cause the Earth's climate to change on very long time scales. Turns out that these astronomical cycles are likely to be the drivers of where you are from and where you live.

  • 794-An Apollo Space Rock to Follow

    26 ABR. 2024 · Recently my Catalina Sky Survey teammate Vivian Carjaval was asteroid hunting in the constellation of Ursa Minor with our Schmidt telescope on Mt. Bigelow when she discovered, 2024 BR4, a two football field diameter Earth approaching asteroid.Vivian’s Apollo asteroid discovery poses no threat to humans since 2024 is as close as it will come to Earth in the next few hundred years.

  • 281E-295-Close Passes

    23 ABR. 2024 · During a recent 3 night observing run my Catalina Sky Survey teammate Rose Matheny discovered 4 asteroids which can come to less than one half the Moon's distance from us. Interestingly one of them passed about 25,000 miles over the South Pole 2 days after Rose discovered it. Rose's four close approaching asteroids are small ranging in size from 15 to 60 feet in diameter. None of them are big enough to reach the Earth's surface and make a crater. However, the largest is about the size of the one whose air blast shock wave injured nearly 1500 people when it exploded over Chelyabinsk, Russia in 2013 .

    19 ABR. 2024 · Perhaps the most dangerous Amor asteroid is 2006 HZ51 .It was discovered by my team the Catalina Sky Survey.  Fortunately the closest 2006 HZ51 will come to our home planet is  June 11 of 2116 when it will pass us harmlessly 26 times the distance to our moon away from us.

  • 280E-294-Dangerous Duo

    16 ABR. 2024 · Recently in the space of 28 hours my Catalina Sky Survey teammates Rose Matheny and Carson Fuls discovered two Potentially Hazardous Asteroids to add to the list of the more than 1700 which asteroid hunters have discovered. Fortunately, none of the Potentially Hazardous Asteroids are currently on a collision course with planet Earth.

  • 792-Closest Approaching Comet

    12 ABR. 2024 · P/1999 J6 (SOHO) was discovered 10 May 1995 by Mike Oates as part of the Citizen Science Sun Grazer Project in which volunteers from all over the world have the chance to discover a comet in images taken by the Solar and Heliospheric Observatory or SOHO for short.RADAR studies of the daytime Arietid ( AIR-ee-uh-tids) meteor shower stream which peaks every June 7 indicates that  P/1999 J6 (SOHO) could be one of the potential parent objects.

  • 279E-293-From Luna

    9 ABR. 2024 · More than 240 Lunar meteorites have been found in the Dhofar region of Oman, on the LaPaz Icefield of Antartica, and other locations on the Earth's surface. These space traveling rocks were blasted from the Moon's surface by the impact of asteroids and comets which accelerated them to speeds greater than the lunar escape velocity of 1.5 miles per second. Subsequently these interplanetary travelers in the night orbited the Sun for an extended period of time before entering our atmosphere and falling to Earth. We know these meteorites are from the Moon because they contain mixtures of atoms which are found on the Moon but not in Earthly rocks.

    5 ABR. 2024 · It all started when Krisztián Sárneczky at the Konkoly Observatory near Budapest, Hungary reported the position and brightness of an unknown asteroid rapidly moving through the constellation of Lynx. Three hours later , the object, now called 2024 BX1 exploded harmlessly in our atmosphere
