Mountaintop glacier ice in the tropics of all four hemispheres covers significantly less area -- in one case as much as 93% less -- than it did just 50 years ago, a new study has found.
While studying two exoplanets in a bright nearby star system, the CHEOPS satellite has unexpectedly spotted the system's third known planet crossing the face of the star. This transit reveals exciting details about a rare planet "with no known equivalent", as the scientific team led by the Universities of Geneva and Bern, and members of the National Center of Competence in Research PlanetS, point out.
Some exoplanet searches could be missing nearly half of the Earth-sized planets around other stars. New findings from a team using the international Gemini Observatory and the WIYN 3.5-meter Telescope at Kitt Peak National Observatory suggest that Earth-sized worlds could be lurking undiscovered in binary star systems, hidden in the glare of their parent stars. As roughly half of all stars are in binary systems, this means that astronomers could be missing many Earth-sized worlds.
While exploring two exoplanets in a bright nearby star system, ESA's exoplanet-hunting Cheops satellite has unexpectedly spotted the system's third known planet crossing the face of the star. This transit reveals exciting details about a rare planet 'with no known equivalent,' say the researchers.
The exoplanet satellite hunter CHEOPS of the European Space Agency (ESA), in which the Instituto de Astrofísica de Canarias (IAC) is participating along with other European institutions, has unexpectedly detected a third planet passing in front of its star while it was exploring two previously known planets around the same star. This transit, according to researchers, will reveal exciting details about a strange planet "without a known equivalent".
An international team including astronomers from UC Davis has observed the first example of a new type of supernova. The discovery, confirming a prediction made four decades ago, could lead to new insights into the life and death of stars.
A worldwide team led by scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion -- an electron-capture supernova. The discovery also sheds new light on the thousand-year mystery of the supernova from A.D. 1054 that was seen all over the world in the daytime, before eventually becoming the Crab Nebula.
A worldwide team led by UC Santa Barbara scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion -- an electron-capture supernova. While they have been theorized for 40 years, real-world examples have been elusive. They are thought to arise from the explosions of massive super-asymptotic giant branch (SAGB) stars, for which there has also been scant evidence.
New research shows how the fundamental law of conservation of charge could break down near a black hole.
Researchers at the National Institute of Standards and Technology (NIST) and Wavsens LLC have developed a method for using radio signals to create real-time images and videos of hidden and moving objects, which could help firefighters find escape routes or victims inside buildings filled with fire and smoke. The technique could also help track hypersonic objects such as missiles and space debris.
