Join us for the 21st Sagan Summer Workshop!

The 2021 Sagan Summer Workshop will focus on young planets and the circumstellar disks from which they form during the first few million years of a star's lifetime. 

More than 99% of the known Universe is composed of plasma. It should then come as no surprise that a solid understanding of basic fluid and plasma dynamics has been the foundation of many of the greatest successes in...

This program is motivated by the recent observational insights concerning white dwarfs as individuals and as a population, based on the astrometry from Gaia and large photometric (e.g. Kepler,TESS, ZTF) and spectroscopic...

Astrometric, photometric and spectroscopic all-sky surveys provide the first complete, unbiased view of the Galactic population of the most abundant type of stellar remnants: white dwarfs.

The Laser Interferometer Space Antenna (LISA) mission is a space-based gravitational wave interferometer planned for launch in 2032. It promises major advances across a wide range of fields in physics and astronomy...

AAVSO's free webinar is from 2:00 pm to about 3:00 pm ET, and features Dr. David Whelan (Austin College) presenting on "Classifying Algol C, the Non-Eclipsing Member of the beta Persei System."

The SKA Science conference 2021, “A precursor’s view of the SKA sky”, is a fully virtual event that has been designed to allow participation from all countries and timezones. The format of the meeting will include...

Gas in the halos of galaxies dominates the universe's baryon budget, traces its dark-matter potential wells, and supplies the fuel for star formation. Circumgalactic gas has also long been suspected to regulate galaxy...
