New detailed observations with NSF's NOIRLab facilities reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in at 25 Earth-masses, and slightly smaller than Neptune, this exoplanet's existence is at odds with the predictions of leading planet formation theories.
NASA's Aqua satellite provided a look at Typhoon Hagupit as it was nearing landfall in southeastern China.
For a long time, researchers have believed that there is not much of interest going on in the Sun during the passive period, therefore not worth studying. Now this assumption is showed to be false by Juha Kallunki, Merja Tornikoski and Irene Björklund, researchers at Metsähovi Radio Observatory, in their peer-reviewed research article published in Solar Physics. This is the first time that astronomers are systematically studying the phenomena of the solar minimum.
The journal Nature Communications today is publishing the discovery of a new type of stars, very rich in phosphorus, which could help to explain the origin of this chemical element in our Galaxy. This achievement has been made by astronomers of the Instituto de Astrofísica de Canarias (IAC) and researchers in computer science from the Centre for Research in Information and Communication Technology (CITIC) at the University of La Coruña (Galicia).
In a series of simulations, an international team of researchers determined that some neutron star collisions not only produce gravitational waves, but also electromagnetic radiation that should be detectable on Earth.
NASA's Aqua satellite obtained visible and water vapor imagery as Tropical Storm Isaias continued moving along the east coast of Florida. On Aug. 3, 2020, warnings and watches stretched from Florida to Maine.
NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of Typhoon Hagupit in the Northwestern Pacific Ocean that showed the development of an eye as it quickly intensified. Imagery also showed a thick band of thunderstorms that resembled a giant tail, spiraling into the powerful storm.
Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with the Atacama Large Millimeter/submillimeter Array (ALMA).
Whether in flood early-warning systems or in agriculture - rainfall measurements are of great importance. However, there is a lack of accurate data for many regions in the world due to the fact that comprehensive measurements have so far been too expensive. Researchers at Karlsruhe Institute of Technology and the University of Augsburg have now succeeded in utilizing the commercial microwave link network operated by mobile network providers for Germany-wide rainfall measurements.
A research team led by Prof. SHANG Zhaohui from National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) has proved that Dome A in Antarctica is the best site for optical astronomical observation on Earth.
