The science team chose to study Eps Ind A because the system showed hints of a possible planetary body using a technique called radial velocity , which measures the back-and-forth wobbles of the host star along our line of sight.
- Cosmic Milestone: NASA Confirms 5,000 ExoplanetsThe archive records exoplanet discoveries that appear in peer-reviewed, scientific papers, and that have been confirmed using multiple detection methods or by analytical techniques. The 5,000-plus planets found so far include small, rocky worlds like Earth, gas giants many times larger than Jupiter, and “hot Jupiters” in scorchingly close ...
- Webb Detects Tiny Quartz Crystals in Clouds of Hot Gas GiantResearchers using NASA’s James Webb Space Telescope have detected evidence for quartz nanocrystals in the high-altitude clouds of WASP-17 b, a hot Jupiter exoplanet 1,300 light-years from Earth. The detection, which was uniquely possible with Webb’s MIRI (Mid-Infrared Instrument), marks the first time that silica (SiO2) particles have been ...
- Exploring Exoplanets | NASA Jet Propulsion Laboratory (JPL)Exoplanet Exploration at JPL JPL is at the forefront of a burgeoning and fascinating endeavor — developing technologies to hunt for exoplanets, which are planets beyond our solar system. Breakthroughs in the 1990s by the world science community confirmed that our Sun, the star at the center of our solar system, is not the only star that has ...
- NASA Data Reveals Possible Reason Some Exoplanets Are Shrinking“Scientists have now confirmed the detection of over 5,000 exoplanets, but there are fewer planets than expected with a diameter between 1.5 and 2 times that of Earth,” said Caltech/IPAC research scientist Jessie Christiansen, science lead for the NASA Exoplanet Archive and lead author of the new study in The Astronomical Journal.
