In a new study, the team of astrophysicists who launched STARFORGE discovered that star formation is a self-regulatory process. In other words, stars themselves set their own masses. This helps explain why stars formed in disparate environments still have similar masses. The new finding may enable researchers to better understand star formation within our own Milky

360° narrowband map of a star forming cloud from the STARFORGE simulations, visit http://starforge.space to see more movies or learn about the project. This 360° movie shows a massive (20,000 solar mass) star forming molecular cloud as it is being destroyed by newly born stars. This happens due to massive stars that are extremely bright

This lecture was presented on October 14, 2021 by Dr. Phil Plait, astronomer and best-selling author. Plait discussed the explosion in exoplanet detections since the 1990s (over four thousand so far!). These planets orbit a wide variety of stars, and themselves are all wildly different; huge, small, hot, cold, airless, or with thick atmospheres. The
Fast radio bursts host galaxies. The bursts are catalogued as FRB 190714, at top left; FRB 191001, at top right; FRB 180924, at bottom left; and FRB 190608, at bottom right. Learn more.

Brainstorm is a podcast by the Daily Northwestern which looks into scientific facts and fiction and the reasons why we believe in them. When you look up at the night sky, do you ever wonder where all those stars came from? Host Neya Thanikachalam spoke to CIERA’s Jeff Andrews to find out. The Daily Northwestern
Vicky Kalogera is a professor of physics and astronomy at Northwestern University and Director of the CIERA Center – leading research, studying the cosmos and making new discoveries. This interview is a special Women’s History Month 2021 segment for CBS Chicago.
Maya Fishbach uses gravitational waves to probe the universe’s most extreme objects — black holes and neutron stars. Her research aims to understand where, when and how these systems of merging compact objects are made. As a member of the LIGO Scientific Collaboration, she analyzes gravitational-wave data to study the population properties of colliding black

The massive black hole in M33 X-7 is hidden in the X-ray bright center of the pancake-like accretion disk of matter. The black-hole’s hot (blue) and massive star companion is losing mass in a wind that gets pulled and captured by the black hole. Learn more.

PhD student Newlin Weatherford, who holds the Riedel Family Graduate Fellowship at CIERA, captured the Great Conjunction (“Christmas Star”) of Jupiter and Saturn on December 21, 2020 at 6:20 pm PT from Novato, California. Using his Panasonic DZ1000, Newlin wasn’t able to resolve Saturn’s rings, but we can see Callisto and Io and many faint

Professor Wen-fai Fong is interviewed for The Cosmic Companion and talks about her work studying kilonova explosions and collisions of neutron stars.
From Purdue University’s Long Tales of Science podcast, hear CIERA’s Dr. Sarah Wellons, an astrophysicist who uses high performance computing resources to run massive simulations of galaxy formation, and her mother, Dr. Helen Wellons, a retired chemical engineer who used parallel computing to deploy computational modeling applications to optimize real-time refinery operations at ExxonMobil.
This image shows the glow from a kilonova caused by the merger of two neutron stars. The kilonova, whose peak brightness reaches up to 10,000 times that of a classical nova, appears as a bright spot (indicated by the arrow) to the upper left of the host galaxy. The merger of the neutron stars is
This animation shows the increasing sample of gravitational wave sources, starting before LIGO-Virgo-KAGRA went online (with only electromagnetic, EM, sources) and then moving through the three main data releases that are now available (GTWC-1, GWTC-2.1, and GWTC-3). Watch as the sample of merging black holes and neutron stars has dramatically increased over the past few

On October 28, 2020 CIERA’s Shane Larson presented this public lecture titled A Storm of Stars: A Living History of the Milky Way in a virtual Zoom webinar format to an audience of nearly 450 viewers. Larson discussed how we came to understand the Milky Way, our home galaxy, and how our ideas about the
