An international group of collaborators, including scientists from NASA s Jet Propulsion Laboratory and The University of New Mexico, have discovered a new, temperate sub-Neptune sized exoplanet with a 24-day orbital period orbiting a nearby M dwarf star. The recent discovery offers exciting research opportunities thanks to the planet s substantial atmosphere, small star, and how fast the system is moving away from the Earth. ....

At the heart of almost every sufficiently massive galaxy there is a black hole whose gravitational field, although very intense, affects only a small region around the centre of the galaxy. Even though these objects are thousands of millions of times smaller than their host galaxies our current view is that the Universe can be understood only if the evolution of galaxies is regulated by the activity of these black holes, because without them the observed properties of the galaxies cannot be explained. Theoretical predictions suggest that as these black holes grow they generate sufficient energy to heat up and drive out the gas within galaxies to great distances. Observing and describing the mechanism by which this energy interacts with galaxies and modifies their evolution is therefore a basic question in present day Astrophysics. ....

A University of Oklahoma doctoral student, graduate and undergraduate research assistants, and an associate professor in the Homer L. Dodge Department of Physics and Astronomy in the University of Oklahoma College of Arts and Sciences are lead authors on a paper describing a changing-look blazar - a powerful active galactic nucleus powered by supermassive blackhole at the center of a galaxy. The paper is published in ....

Astrophysicists say that the benzene ring could be the fundamental building block of polycylic aromatic hydrocarbons or PAHs, the most basic materials formed from the explosion of dying, carbon-rich stars. That swirling mass of matter would eventually give shape to the earliest forms of carbon - precursors to molecules some scientists say are connected to the synthesis of the earliest forms of life on Earth. ....

When Roman launches in the mid-2020s, these devices will convert starlight into electrical signals, which will then be decoded into 300-megapixel images of large patches of the sky. These images will allow astronomers to explore a vast array of celestial objects and phenomena, bringing us closer to solving many pressing cosmic mysteries. As the telescope s eyes, Roman s detectors will enable all of the mission s science, said John Gygax, the focal plane system manager for the Roman Space Telescope at NASA s Goddard Space Flight Center in Greenbelt, Maryland. Now, based on our testing results, our team can confirm these infrared detectors meet all the requirements for Roman s purposes. ....
