Mike Brown, Konstantin Batygin, and Linda Spilker sat with Emily Lakdawalla and Mat Kaplan for an episode of Planetary Radio Live that was all about the mystery unfolding around "Planet 9."
Lecture 14 of Dr. Bruce Betts' 2016 online Introductory Planetary Science and Astronomy course covers galaxies (our place in the Milky Way, types of galaxies, Hubble Deep Field), the Universe (determining distances, expansion of the universe, Big Bang theory and evolution of the universe, WMAP and Planck results, dark matter, dark energy, neutrinos), and life in the universe (Earth life requirements, astrobiology, SETI). Recorded at California State University Dominguez Hills.
Lecture 13 of Dr. Bruce Betts' 2016 online Introductory Planetary Science and Astronomy course continues exploring the Sun (physical characteristics, zones, solar cycle, sunspots, flares, coronal mass ejections, fusion, etc.) and covers stars and stellar evolution (star types and colors, evolution, HR Diagrams, birth and death phases, white dwarfs, neutron stars, black holes). Recorded at California State University Dominguez Hills.
Lecture 12 of Dr. Bruce Betts' 2016 online Introductory Planetary Science and Astronomy course covers exoplanets (planets around other stars) including discovery techniques, current knowledge and characteristics, and multi-planet systems. Lecture 12 also covers the Sun and solar physics. Recorded at California State University Dominguez Hills.
In this episode of SciTech, we take you up to the telescope in the sky, SOFIA. Check out the technology and science behind operating a telescope in an airplane as we go for an overnight ride in the Stratospheric Observatory for Infrared Astronomy.
Lecture 11 of Dr. Bruce Betts' 2016 online Introductory Planetary Science and Astronomy course covers the heliosphere, Oort Cloud, light pressure, solar sails, solar effects, comets, origin of solar system, and the laws of planetary motion. Recorded at California State University Dominguez Hills.
It's been a busy two months of testing for The Planetary Society's LightSail 2 spacecraft.
Engineers spun the CubeSat like a record and shined flashlights in its electronic eyes in order to make sure everything goes according to plan when the solar sail heads into space. LightSail will soon be transported to Utah State University's Space Dynamics Laboratory, where it will be flooded with magnetic fields in order to calibrate the spacecraft's attitude control system.
This short video showcases tests of the spacecraft's momentum wheel, gyroscopes, deployment motor and sun sensors.
Robert Picardo brings you the third installment of the Planetary Post, a monthly newsletter/video keeping you up to date on space news.
An asteroid or comet headed for Earth is the only large-scale natural disaster we can prevent. Working together to fund our Shoemaker NEO Grants for astronomers, we can help save the world.
