Life in the Universe

Abraham Loeb, Chair of the Astronomy Department, Founding Director of the Black Hole Initiative, Director of the Institute for Theory and Computation  Harvard University ASTRONOMY TALK | Is life most likely to emerge at the present cosmic time near a star like the Sun? Dr. Loeb will review the habitability of the universe throughout cosmic […]

The Restless Universe: Palomar Transient Factory

Dan David Prize Winner, Shrinivas Kulkarni California Institute of Technology Cosmic explosions were first noted nearly two thousand years ago but only in the past hundred years have astronomers secured recognition of classes of explosions ranging from exotic eruptions to the death of stars (supernovae). The Palomar Transient Factory (PTF) and its successor, the Zwicky Transient Factory […]

Fingerprints of the first stars: Searching for Population III with Keck

Our current story for the origin of the heavy elements has at its core a recycling program on the grandest of scales. Using Keck, we have traced atoms as they flow from the intergalactic medium into galaxies, where they are incorporated into stars, undergo fusion, and are returned in supernovae and other types of stellar […]

Focusing the Distant Universe with Gravitational Lensing

Observing distant objects allows us to peer back in time to early stages of the universe, across the most active period of galaxy growth when most stars were born. While galaxies are challenging to study at such large distances, nature occasionally gives us an advantage through the phenomenon of gravitational lensing. The lensing effect can […]

Astronomy Talk: The Remaining 95 Percent: Insights From Gravitational Lensing

In our standard model of cosmology, only five percent of the mass-energy budget of the Universe is accounted for by particles that have been detected in Earth-based laboratories. The remaining 95 percent, called dark matter and dark energy, has only been detected gravitationally via astronomical observations. Although the abundance of dark matter and dark energy […]

The 2015-16 El Niño: Wind on the Water and the Weather on Mauna Kea

In 2015, the global wind machine fired up record numbers of powerful hurricanes in the central Pacific, with several making close passes to the Island of Hawaii. Is it possible that the Island of Hawaii is protected from a direct hurricane impact by Mauna Loa and Mauna Kea? What does the historical record tell us? […]

Life in the Universe: The Science of Astrobiology

Is life common in the universe, or rare? Humans have pondered this question for millennia. Today we are privileged to be able to bring the tools of modern science to answer questions that were once the province of philosophers and theologians. In this Astronomy Talk, Dr. Carl Pilcher, Interim Director of the NASA Astrobiology Institute, […]

Astronomy Talk: Where We Came From — How Solar Systems Form

Where We Came From — How Solar Systems Form How common are Earths? Unknown just a generation ago, more than 2,000 planets have been discovered orbiting other stars in our galaxy and Hawaii’s own Keck Observatory has been at the forefront of this incredibly exciting field. We have invited Professor Greg Laughlin, an expert on […]
