Illustration of gas-giant planet COCONUTS-2b. Credit: B. Bays (SOEST/UH) Astronomers have discovered thousands of exoplanets — planets beyond our solar system — but few have been directly imaged, because they are extremely difficult to see with existing telescopes. A University of Hawaiʻi Institute for Astronomy (IfA) graduate student has beaten […]

An image of NEID’s spectroscopic observations of the Sun. NEID’s spectral coverage extends significantly redder and bluer than the limits of human vision, enabling it to observe many critical spectral lines. NEID’s design enables high spectral resolution, large wavelength coverage, and exquisite stability. The image is inspired by the classic […]

Artist’s impression of the Nu2 Lupi planetary system. Credit: © ESA Photobombs — when something or someone unexpectedly enters a camera’s field of sight during the taking of a photograph — happen every day. Sometimes it is a friend, other times a stranger or perhaps a bird. Rarely, however, is […]

Artist’s impression of exoplanet, showing tilted axis of rotation (adapted from NASA original image). Credit: NASA JPL Planets which are tilted on their axis, like Earth, are more capable of evolving complex life. This finding will help scientists refine the search for more advanced life on exoplanets. This NASA-funded research […]

This illustration depicts a planet partially hidden in the glare of its host star and a nearby companion star. After examining a number of binary stars, astronomers have concluded that Earth-sized planets in many two-star systems might be going unnoticed by transit searches, which look for changes in the light […]

Artist’s illustration of an alien world.   ANIMATION Scientists at Cornell University and the American Museum of Natural History have identified 2,034 nearby star-systems — within the small cosmic distance of 326 light-years — that could find Earth merely by watching our pale blue dot cross our sun. That’s 1,715 star-systems […]

Protoplanetary disks are classified into three main categories: transition, ring, or extended. These false-color images from the Atacama Large Millimeter/submillimeter Array (ALMA) show these classifications in stark contrast. On left: the ring disk of RU Lup is characterized by narrow gaps thought to be carved by giant planets with masses […]

An artist’s impression shows an exoplanet orbiting the Sun-like star. Credit: ESO/M. Kornmesser 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.

Artist’s impression of the surface of Gliese 486b. Credit: RenderArea  ANIMATION MAROON-X instrument built by University of Chicago team measures its first planet. In the past two decades, scientists have discovered more and more planets orbiting distant stars—but in some sense, they’re still just dots on a map. “It’s kind […]
