Cambridge, MA (October 23, 2019)—A new era of variable star astronomy starts as the American Association of Variable Star Observers (AAVSO) now welcomes spectra observations from the AAVSO community.
CAMBRIDGE, Mass. (October 14, 2019)—Compiling together multiple pieces of information for each of a million-plus objects is no easy or quick task, but that is exactly what Sebastián Otero, Patrick Wils, Patrick Schmeer, and Klaus Bernhard did.
CAMBRIDGE, Mass. (Sept. 26, 2019)—For the past ten years, under the guiding hand of Editor-in-Chief Professor John Percy (University of Toronto), the Journal of the American Association of Variable Star Observers (JAAVSO) has flourished. Starting October 1, 2019, the scholarly journal’s pages will see new Editor-in-Chief Professor Nancy Morrison (University of Toledo) at the keyboard implementing her vision.
A group of astronomers led by Dr. James Miller-Jones of Curtin University and the International Centre for Radio Astronomy Research have published a revised distance to the famed variable star SS Cygni, solving a major mystery surrounding this star and its behavior. Their work was made possible due to the dedication of dozens of observers worldwide who monitor SS Cygni and report their observations to the American Association of Variable Star Observers (AAVSO).
Welcome to the AAVSO's special webpage devoted to SN 2011fe!
SN 2011fe is the brightest supernova as seen from Earth in nearly 20 years. It's a rare event that astronomers around the world are excited about -- it's not only a beautiful spectacle, it may also teach us new things about supernovae and the universe that we live in. Here you'll find information on what SN 2011fe is, why astronomers around the world are watching it, and most importantly, how you can make your own observations and help create a scientific record of this supernova!
Un proyecto de ciencia ciudadana en desarrollo desde hace más de 100 años alcanzó un punto clave este mes, cuando un astrónomo aficionado contribuyó con la observación número 20 millones de una estrella variable.
