Simulations offer insight into what previously had been limited to extrapolations and theoretical calculations By aiming intense X-ray beams at iron samples, scientists have discovered what may lie at the core of “super-Earths,” rocky planets triple the mass of Earth orbiting far-distant stars.

Planetary scientist Sarah Hörst successfully replicates different forms of planetary haze—important models that will inform the study of exoplanets.
Researcher Dr. Sarah Hörst and her team have recreated the chemistry of atmospheres on distant planets for the first time in the lab. The study was published in Nature Astronomy this week.
Conditions in crowded urban settlements in Africa make the effects of climate change worse, pushing temperatures to levels dangerous for children and the elderly in those areas, according to a new study led by a Johns Hopkins University scientist. Article written by Arthur Hirsch
Professor Anand Gnanadesikan and Assistant Professor Ciaran Harman are featured in, "Super Hurricanes: Inside Monster Storms." The film, which comes after two of the most devastating hurricanes in decades, airs on the Science Channel at 9 p.m. EST on Friday, Sept. 22.
This morning, after two decades in space, NASA’s Cassini spacecraft ended an incredible journey of exploration. With the spacecraft’s fuel spent, operators deliberately plunged Cassini into Saturn—which it had orbited for 13 years —to make sure the planet’s moons remain pristine for future exploration. A small but significant piece of the Johns Hopkins Applied Physics […]
Meghan Avolio earned her PhD in Ecology and Evolutionary Biology from Yale University and is a plant ecologist studying the mechanisms by which global change drivers, including urbanization, impact the diversity of plant populations and communities. Her research addresses the consequences of global change for individual plants up to entire ecosystem functioning. Meghan has joined us […]
Congratulations to our very own Dr. Sarah Horst for being selected to receive Johns Hopkins Catalyst Award. In July 2017, thirty-four early career faculty members were selected to receive Johns Hopkins Catalyst Awards, an honor that is accompanied by a $75,000 grant, mentoring opportunities, and institutional recognition. Recipients include faculty composing new musical work inspired […]
Assistant Professor Sarah Hörst’s research was featured in The Baltimore Sun. She and her team of graduate student researchers are helping other planetary scientists prepare for future discoveries by showing them what conditions they might encounter in the atmospheres of distant bodies.
Research ideas can come from the unlikeliest of places. Just ask Anna Scott, a graduate student in the Department of Earth & Planetary Sciences.
