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.

Exploring Hd 20794 D
The confirmed discovery of exoplanets revolutionized our understanding of the universe. Among the thousands of confirmed exoplanets, HD 20794 d in particular, recently attracted attention for a unique characteristic – an eccentric orbit that moves in and out of the parent star’s habitable zone. Astronomers are studying this planet to gain insights into habitability beyond Earth.

Close Encounters Of The Rocky Kind
The space around us is hardly empty – there’s millions of asteroids orbiting the Sun along with the Earth and other planets in our solar system. But one day every year we come together to acknowledge these space rocks and the impact they often have on our home. That day is June 30, also known as asteroid day. As asteroid day approaches this year, so will an asteroid called 2011 UL21.
