Discovered in March by astronomers using the Zwicky Transient Facility’s wide-field survey camera at the Palomar Observatory in San Diego County, California, Comet C/2022 E3 (ZTF) was last visible in the night sky during the Stone Age — about 50,000 years ago.

Using observations collected from 2009 to 2021 CIERA Professor Jason Wang has assembled a time lapse video of HR8799, the first directly imaged extrasolar planetary system. The video shows a family of four exoplanets, each more massive than Jupiter, orbiting their star and gives viewers an unprecedented glimpse into planetary motion. To construct the video,

The researchers say that by studying similar star systems, we can learn more about potentially habitable planets beyond Earth. Ultracool dwarfs are much fainter and dimmer than the sun, so any worlds with liquid water on their surfaces — a crucial ingredient to form and sustain life — would need to be much closer to

Affectionately referred to as the B.O.A.T. (“brightest of all time”), the powerful explosion occurred approximately 2.4 billion light-years away from Earth, in the direction of the constellation Sagitta. Astrophysicists, including Jillian Rastinejad, first detected the GRB, which was a few hundred seconds in duration, in gamma-ray light on Oct. 9. Read the full Northwestern News

This Gemini North image, superimposed on an image taken with the Hubble Space Telescope, shows the telltale near-infrared afterglow of a kilonova produced by a long GRB (GRB 211211A). This discovery challenges the prevailing theory that long GRBs exclusively come from supernovae, the end-of-life explosions of massive stars. Read the full Northwestern News story: December

This artist’s impression shows a kilonova produced by two colliding neutron stars. While studying the aftermath of a long gamma-ray burst (GRB), two independent teams of astronomers using a host of telescopes in space and on Earth, including the Gemini North telescope on Hawai‘i and the Gemini South telescope in Chile, have uncovered the unexpected

Gamma-ray burst 211211A, the location of which is circled in red, erupted on the outskirts of a spiral galaxy around 1 billion light-years away in the constellation Boötes. The NASA/ESA Hubble Space Telescope captured the image with its Wide Field Camera 3 and Advanced Camera for Surveys. Read the full Northwestern News story: December 7,

Two neutron stars begin to merge in this illustration, blasting a jet of high-speed particles and producing a cloud of debris. Scientists think these kinds of events are factories for a significant portion of the universe’s heavy elements, including gold. Read the full Northwestern News story: December 7, 2022

The kilonova and gamma-ray burst is on the right. The blue color represents material squeezed along the poles, while the red colors indicate material ejected by the two inspiralling neutron stars that is now swirling around the merged object. A disk of ejecta emitted after the merger, hidden behind the red and blue ejecta, is shown in
