Ever Wonder Why Some Meteor Showers Are So Unpredictable?
April 16, 2025, Mountain View, CA -- Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? In a paper published online in the journal Icarus this week, two SETI Institute researchers show that this is not due to the random pull of the planets, but rather the kick they receive from a moving Sun.

In The Pinball World Of Asteroids
March 31, 2025, Mountain View, CA -- In April 2019, rare primitive meteorites fell near the town of Aguas Zarcas in northern Costa Rica. In an article published online in the journal Meteoritics & Planetary Science, an international team of researchers describe the circumstances of the fall and show that mudball meteorites are not necessarily weak.

New Meteor Shower In The Constellation Cassiopeia
In the early morning of September 4, there was a brief meteor shower outburst visible over California and Arizona with a radiant in the constellation Cassiopeia. It was recorded by low-light video cameras in the CAMS networks led by Peter Jenniskens (SETI Institute) and Nick Moskovitz (Lowell Observatory). The outburst revealed a weak annual shower that had not been mapped before, with a possible earlier outburst in 2014. The shower was caused by the crumbs of a yet-to-be discovered comet in a …

Nature'S July Fireworks
Several meteor showers are active on July 4, but a new one was just discovered that peaks on this day. The shower is in the southern hemisphere in the constellation of Fornax and called the psi-Fornacids. The figure above shows the direction of all triangulated meteors detected by the CAMS network and the Global Meteor Network this year, plotted on the celestial sphere. Each dot is a triangulated meteor. Meteor showers are shown in colors proportional to speed: red = fast, blue = slow. The new …
