The shortest-period gas-giant exoplanet discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international group of astronomers has detected a new, ultra-hot gas giant exoplanet with an extremely short orbital period. The newfound alien world, designated TOI-2109b is about five ti.....»»
Radio emission detected from the Vela X-1 bow shock
An international team of astronomers has conducted radio observations of a bow shock in the X-ray binary Vela X-1 using MeerKAT telescope. The observational campaign resulted in the detection of radio emission from this source. The finding is detaile.....»»
Could we really deflect an asteroid heading for Earth? An expert explains NASA"s latest DART mission
A NASA spacecraft the size of a golf cart has been directed to smash into an asteroid, with the intention of knocking it slightly off course. The test aims to demonstrate our technological readiness in case an actual asteroid threat is detected in th.....»»

The role of animal pheromones in regulating fat burning and longevity
Pheromones are potent molecules that mediate communications between animals and even between humans. Usually, a sender animal synthesizes and excretes pheromones to the environment; pheromones are detected by a receiver animal and elicit dramatic cha.....»»
Using machine learning to derive black hole motion from gravitational waves
The announcement that the Laser Interferometer Gravitational-wave Observatory (LIGO) had detected gravitational waves during the merger of two black holes sent ripples throughout the scientific community in 2016. The earthshaking news not only confir.....»»
Satellites detect large methane emissions from Madrid landfills
High-resolution satellites have detected substantial quantities of methane leaking from adjacent landfill sites close to the center of Madrid, Spain. Using data from the Copernicus Sentinel-5P mission combined with GHGSat's high-resolution commercial.....»»
Lack of massive black holes in telescope data is caused by bias
Our telescopes have never detected a black hole more massive than 20 times the mass of the sun. Nevertheless, we now know of their existence as dozens of those black holes have recently been "heard" to merge via gravitational wave radiation. A team o.....»»
