How Newborn Stars Prepare for the Birth of Planets
National Radio Astronomy Observatory

An international team of astronomers used two of the most powerful radio telescopes in the world to create more than three hundred images of planet-forming disks around very young stars in the Orion Clouds. These images reveal new details about the birthplaces of planets and the earliest stages of star formation.

NASA planet hunter finds its 1st Earth-size habitable-zone world
NASA Goddard Space Flight Center

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star's habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface.

How to Build a 3D Map of the Universe – and Why
Department of Energy, Office of Science

In the 1980s, Saul Perlmutter at the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (LBNL) and his collaborators realized that they could use data about supernovae to research the history of the universe. They expected to see that very distant supernovae appear a bit brighter than they would in an expanding universe that wasn’t slowing in its growth. The data revealed something else entirely.

Comet-Enabled Simulations Showcase Black Holes and Their Magnetic Bubbles
University of California San Diego

University of California and Princeton scientists have been collaborating on a computational astrophysics project to learn more about the recent discovery of a black hole, which sits in the middle of a galaxy called Messier 87 (M87), approximately 55 million light years from Earth.

TESS finds its first Earth-sized planet
Carnegie Institution for Science

A nearby system hosts the first Earth-sized planet discovered by NASA's Transiting Exoplanets Survey Satellite, as well as a warm sub-Neptune-sized world, according to a new paper from a team of astronomers that includes Carnegie's Johanna Teske, Paul Butler, Steve Shectman, Jeff Crane, and Sharon Wang.

National Ignition Facility Reveals How Hydrogen Becomes Metallic Inside Giant Gas Planets
Lawrence Livermore National Laboratory

Swirling dense metallic hydrogen dominates the interiors of Jupiter, Saturn and many extra-solar planets. Building precise models of these giant planets requires an accurate description of the transition of pressurized hydrogen into this metallic substance – a long-standing scientific challenge. In a paper published by Science, a research team led by scientists at Lawrence Livermore National Laboratory describes optical measurements of the insulator-to-metal transition in fluid hydrogen, resolving discrepancies in previous experiments and establishing new benchmarks for calculations used to construct planetary models. The multi-institution team included researchers from the French Alternative Energies and Atomic Energy Commission, University of Edinburgh, University of Rochester, Carnegie Institution of Washington, University of California, Berkeley and The George Washington University.

WVU Expert Says Water on Mars Would Be Extremely Acidic but Could Host Life
West Virginia University

With new and compelling evidence for water existing beneath the south pole of Mars, a West Virginia University professor says this underground lake is likely to be extremely salty and more acidic than battery acid. Life forms that can survive in extreme physical and geochemical conditions are found in abundance in acid salt lakes such as those in Chile and western Australia, she said.
