NASA's Goddard Space Flight Center 11 Feb 2020, 14:18 UTC In February 2020, NASA’s Solar Dynamics Observatory — SDO — is celebrating its 10th year in space. Over the past decade the spacecraft has kept a constant eye on the Sun, studying how the Sun creates solar activity and drives space weather — the dynamic conditions in space that impact the entire solar system, including Earth.
McDonald Observatory 10 Feb 2020, 17:15 UTC A team of astronomers led by Brendan Bowler of The University of Texas at Austin has probed the formation process of giant exoplanets and brown dwarfs, a class of objects that are more massive than giant planets, but not massive enough to ignite nuclear fusion in their cores to shine like true stars. Using direct imaging with giant ground-based telescopes, they studied the orbits of these faint companions orbiting stars in 27 systems. These data, combined with modeling of the orbits, allowed them to determine that the brown dwarfs in these systems formed like stars, but the gas giants formed like planets. The research is published in the current issue of The Astronomical Journal.
ESA Human Spaceflight and Exploration 7 Feb 2020, 12:42 UTC Just two days after landing in the steppes of Kazakhstan, watch live as ESA astronaut Luca Parmitano shares his spaceflight experiences with media in Europe.
Harvard-Smithsonian Center for Astrophysics 4 Feb 2020, 13:36 UTC Scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) have completed the Extremely Low Mass--also known as ELM--spectroscopic study of white dwarf stars in the Sloan Digital Sky Survey (SDSS). In process for more than a decade, the completed survey discovered 98 detached double white dwarf binaries.
NASA's Goddard Space Flight Center 31 Jan 2020, 12:30 UTC The galaxy depicted in this image taken by the NASA/ESA Hubble Space Telescope is a barred spiral known as NGC 7541, in the constellation of Pisces (the Fishes).
Max Planck Institute for Radio Astronomy 30 Jan 2020, 10:38 UTC Observations using 21 telescopes of the European VLBI Network (EVN) have revealed that a cosmic explosion, called AT2018cow most likely formed a neutron star with an extremely powerful magnetic field - known as a magnetar. The high-resolution radio images produced in this new study show physical properties of the stellar remnant that make alternative explanations less likely, say scientists.
