Alex Filippenko

In the media

Filippenko is frequently featured in the History Channel series The Universe, as well as in the series How the Universe Works. Overall, he has participated in more than 120 science documentaries.

Filippenko is the author of and teacher in an eight-volume teaching series on DVD called Understanding the Universe. Organized into three major sections in ten smaller units, this series of 96 half-hour lectures covers the material of an undergraduate survey course for An Introduction to Astronomy (the series' subtitle). His other videos courses are Black Holes Explained and Skywatching: Seeing and Understanding Cosmic Wonders.

With co-author Jay M. Pasachoff, Filippenko also wrote the award-winning introductory textbook The Cosmos: Astronomy in the New Millennium, now in its fifth edition (2019).

Honors and awards

Filippenko was awarded the Newton Lacy Pierce Prize in Astronomy in 1992 and a Guggenheim Fellowship in 2000. In 1997, the Canadian Astronomical Society invited him to give the Robert M. Petrie Prize Lecture for his significant contributions to astrophysical research. He was also invited to give the 42nd Oppenheimer Memorial Lecture in 2012. He was recognized in the 2007 Gruber Cosmology Prize for his work with then Miller Postdoctoral Fellow Adam G. Riess and for his highly specialized contributions in measurement of the apparent brightness of distant supernovae, which accurately established the distances that support the conclusion of an increasingly rapid expansion of the universe. (Riess shared the 2011 Nobel Prize in Physics for the discovery.) Filippenko was elected to the California Academy of Sciences in 1999, the National Academy of Sciences in 2009, and the American Academy of Arts and Sciences in 2015. In 2021 he was elected as a Fellow of the American Astronomical Society. He shared the 2015 Breakthrough Prize in Fundamental Physics with Brian P. Schmidt, Adam Riess, Saul Perlmutter, the High-Z Supernova Search Team, and the Supernova Cosmology Project.

In addition to recognition for his scholarship, he has received numerous honors for his undergraduate teaching and public outreach, including the 2007 Richtmyer Memorial Award given annually by the American Association of Physics Teachers and the Carl Sagan Prize for Science Popularization by Wonderfest in 2004. In 2006 Filippenko was awarded the US National Professor of the Year Award, sponsored by The Carnegie Foundation for the Advancement of Teaching and administered by the Council for Advancement and Support of Education (CASE). He also won the 2010 Richard H. Emmons Award for excellence in college astronomy teaching, issued by the Astronomical Society of the Pacific. In 2022, he was awarded the American Astronomical Society's Education Prize. His teaching awards at Berkeley include the Donald S. Noyce Prize for Excellence in Undergraduate Teaching in the Physical Sciences as well as other awards recognizing his undergraduate instruction and mentorship. The Berkeley student body has also voted him nine times as the university's "Best Professor".

He served as President of the Astronomical Society of the Pacific from 2001 to 2003. In 1988, he was selected for a UC Santa Barbara Distinguished Alumni Award, and in 2017 he received a Caltech Distinguished Alumni Award. In 2021, he became an elected fellow of the American Astronomical Society, and in 2022, the society awarded him the AAS Education Prize.

Controversies

In April 2015, Filippenko forwarded an email message from UC Santa Cruz Professor Sandra Faber regarding the controversial construction of the Thirty-Meter Telescope on Mauna Kea. In that message, Faber stated that "The Thirty-Meter Telescope is in trouble, attacked by a horde of native Hawaiians who are lying about the impact of the project on the mountain and who are threatening the safety of TMT personnel. Government officials are supporting TMT’s legality to proceed but are not arresting any of the protestors who are blocking the road.". Faber encouraged astronomers to read more about the TMT protests and to sign a pro-TMT petition written by Mailani Neal, a native Hawaiian high-school student. Filippenko forwarded that email to a group of more than 200 astronomers on U.C. Berkeley's astronomy e-mail list, stating "From Sandy Faber (but I support what she says)." Some people inside and outside of the astronomy community reacted with shock and opposition to the e-mails, the allegedly false claim that TMT personnel were in danger (personnel were not allowed to pass, with verbal and potential physical threats to those who wanted to do so), and the reference to a "horde of native Hawaiians who are lying."

After briefly apologizing in a hastily written email message sent from his iPhone, Filippenko later issued a longer statement. There, he appears to sincerely apologize for not editing Faber's message before forwarding it, explaining that he had been busy in an administrative meeting at that time and had not carefully read her message. He explicitly acknowledges the “insensitive and inflammatory” language that had been used in Faber's message, saying that he had meant to write “I support the petition” instead of “I support what [Faber] says.” Filippenko's statement also argues against the anti-TMT position of many Native Hawaiians, claiming good-faith negotiations with Native Hawaiians communities, and otherwise justifying the siting of the TMT over some Native Hawaiian objection to further desecration of a site sacred to them. Such sentiments have been expressed by many others as well. The American Astronomical Society issued a statement reiterating its formal anti-racist stance and noted the disagreement over whether Filippenko's apology was indeed "sincere and unqualified." Both Faber and Filippenko have refused media requests for comment since the incident.

Personal life

Filippenko is married to Noelle Filippenko and has four children: Zoe, Simon, Caprielle, and Orion.
