Artist’s interpretation of the calcium-rich supernova 2019ehk. Shown in orange is the calcium-rich material created in the explosion. Purple coloring represents gas shedded by the star right before the explosion, which then produced bright X-ray emission when the material collided with the supernova shockwave.

Zwicky Transient Facility composite image of SN2019yvq (blue dot in the center of the image) in the host galaxy NGC 4441 (large yellow galaxy in the center of the image), which is nearly 140 million light-years away from Earth. SN 2019yvq exhibited a rarely observed ultraviolet flash in the days after the star exploded. Learn

A direct image of CSS161010’s host galaxy taken with W. M. Keck Observatory’s DEIMOS instrument, shown in the bottom square and magnified in the larger top square. Observations show it is a dwarf galaxy located 500,000,000 light years away in the direction of the constellation Eridanus. Learn more: Astrophysicists Capture New Class of Transient Objects

A detailed simulation of a black hole’s accretion disc created by a global team of computational astrophysicists – including CIERA’s Prof. Sasha Tchekhovskoy – solved a decades-old mystery. The accretion disc is matter that orbits and then falls into a black hole. Researchers discovered how the disc aligns with the hole’s equator, details vital to
Episode 8 of the documentary series “LIGO: The Discovery that Shook the World” features CIERA Director Vicky Kalogera discussing the science of future LIGO instruments (the detectors that observe gravitational waves). All 8 episodes can be found on YouTube.
The Advanced LIGO Documentary Project was a collaboration among Caltech, MIT, the LIGO Laboratory and director Les Guthman that made the feature documentary, “LIGO,” and the eight-part video series, THE DISCOVERY THAT SHOOK THE WORLD, about LIGO’s major gravitational wave discoveries 2015-2017 and the birth of the new era of gravitational wave astronomy.
The Universe is vast beyond anything humans can easily comprehend, and it is easy to become overwhelmed by the immensity, disheartened by how insignificant we seem. But in the vastness there is a glimmer of truth that we should hold onto and use to guide us: in all the vastness we are, so far as

This lecture was presented by award-winning author and Yale professor Dr. Priyamvada Natarajan at Cahn Auditorium on October 24, 2019. Natarajan discussed how mapping over time encodes radical new scientific ideas. She walked through the history of the acceptance of new astronomical ideas, and talked about the status of several current transformative (and deeply contested)

Cliff Johnson (Northwestern University) and colleagues took this image using the Dark Energy Camera on the 4-meter Blanco Telescope at the Cerro Tololo Inter-American Observatory. Nineteen Starlink satellite trails crossed the image during the six-minute exposure. The image was taken as part of the DELVE survey, which is mapping the outskirts of the Magellanic Clouds,
