NASA JPL (Jet Propulsion Laboratory) scientists led by Tiffany Kataria studied HD 80606 b, an extreme hot Jupiter with a highly elliptical 111-day orbit around its Sun-like star.

JWST's (James Webb Space Telescope) MIRI (Mid-Infrared Instrument) captured the exoplanet's temperature skyrocketing by 1,100 degrees Fahrenheit during periastron, revealing methane and carbon dioxide signatures through spectroscopic analysis of secondary eclipse data.

Kataria's team reports Webb detected more extreme temperature increases than NASA's retired Spitzer Space Telescope predicted, enabling real-time observation of atmospheric chemistry changes across varying conditions.

UCLA (University of California Los Angeles) graduate student Tunhui Xie and Professor Jean-Luc Margot led the most extensive radar study of Jupiter's ocean moon Europa using ground-based telescopes.

NASA's Goldstone Solar System Radar transmitted 3.5-centimeter radio waves between 2011 and 2024, while NSF's (National Science Foundation) Green Bank Telescope received signals revealing unusually high radar albedo from clean, porous ice.

Researchers confirmed coherent backscatter opposition effect in Europa's ice, providing constraints on subsurface transparency that will help interpret NASA's Europa Clipper ice-penetrating radar data.

Stanford University postdoctoral fellow Miltiadis Michailidis analyzed NASA's Fermi Gamma-ray Space Telescope data to uncover gamma rays from supernova remnant G189.6+3.3, hidden near the bright Jellyfish Nebula.

Fermi's LAT (Large Area Telescope) detected neutral pion decay gamma-ray signatures from accelerated protons, placing both remnants approximately 6,000 light-years away with explosion centers separated by roughly 40 light-years.

Michailidis concludes this represents the first known binary system where both massive stars underwent supernova explosions, with delays between detonations potentially extending 100,000 years.

Brock University Assistant Professor Tanya Kizovski led an international team that identified a completely new rock type on Mars, discovering garnet in Martian samples for the first time ever.

University of Portsmouth's Electron Microscopy Unit and Royal Ontario Museum laser equipment analyzed meteorite NWA 8171, revealing garnet chemistry indicating metamorphism from extreme heat, high pressure, or magmatic intrusion.

Professor James Darling states the garnet preserves clues about temperatures, pressures, and processes shaping Mars billions of years ago, opening new windows into planetary evolution.

Northwestern University postdoctoral associate Aneesh Baburaj led JWST (James Webb Space Telescope) observations of GJ504b, the coldest planetary-mass companion ever directly imaged from ground-based instruments at 57 light-years distant.

JWST spectroscopy revealed water vapor, methane, carbon dioxide, and ammonia in the 550-degree Fahrenheit atmosphere, with models requiring salt clouds to explain observed signatures accurately.

Baburaj reports this provides first direct evidence for theorized salt clouds in cold atmospheres, advancing techniques for studying increasingly dim, Jupiter-like worlds beyond current ground-based capabilities.
