Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type. An international collaboration including CNRS researchers has discovered an unusual planetary system, dubbed WASP-148, using the French instrument SOPHIE at the Observatoire de Haute-Provence (CNRS/Aix-Marseille Université;).
Recently, an international research team led by Dr. CHENG Cheng from Chinese Academy of Sciences South America Center for Astronomy (CASSACA) observed four extragalactic galaxies by using the FAST 19-beam receiver, and detected the neutral hydrogen line emission from three targets with only five minutes of exposure each. This is the first publication for FAST to detect extragalactic neutral hydrogen.
Scientists have identified the binary star Eta Carinae as a new kind of source for very high-energy (VHE) cosmic gamma-radiation. Eta Carinae is located 7500 lightyears away in the constellation Carina in the Southern Sky and, based on the data collected, emits gamma rays with energies up to 400 gigaelectronvolts (GeV), some 100 billion times more than the energy of visible light, as the team reports in the journal Astronomy & Astrophysics.
Tiny diamond crystals could be used as an incredibly sensitive and small gravitational detector capable of measuring gravitational waves, suggests new UCL-led research.
A team led by researchers at MIT LIGO Laboratory has measured the effects of quantum fluctuations on objects at the human scale.
The surviving core of a gas giant has been discovered orbiting a distant star by University of Warwick astronomers, offering an unprecedented glimpse into the interior of a planet.
A new model points to the coronoe of supermassive black holes at the cores of active galaxies to help explain the excess neutrinos observed by the IceCube Neutrino Observatory.
KELT-9 b is one of the hottest planets known. New measurements from NASA's Transiting Exoplanet Survey Satellite (TESS) have enabled astronomers to greatly improve their understanding of this bizarre world.
On a quest to find the Universe's largest black holes, Vanderbilt researcher identifies the center of the solar system within 100 meters.
Using the European Southern Observatory's Very Large Telescope (VLT), astronomers have discovered the absence of an unstable massive star in a dwarf galaxy. Scientists think this could indicate that the star became less bright and partially obscured by dust. An alternative explanation is that the star collapsed into a black hole without producing a supernova.
