For over 70 years, astronomers have been scanning for radio or optical signals from other civilizations in the search for extraterrestrial intelligence...
In a study published on April 25, 2022 in the Astrophysical Journal Supplement Series, astronomers analyzed archival spectroscopic and photometric data...
The gravity of a large object in space can keep a smaller object from spinning, a phenomenon called tidal locking. The discovery and characterization of...
It’s raining vaporized rock on WASP-178b, and KELT-20b has its upper atmosphere getting hotter rather than cooler because it is being sunburned by intense...
Using the Subaru Telescope and the NASA/ESA Hubble Space Telescope, astronomers have found evidence for a Jupiter-like protoplanet around the young star...
The atmosphere of Jupiter is enriched with heavy elements by a factor of about 3 compared to a protosolar composition. The origin of this enrichment and...
The case for methane as a biosignature stems from its instability in the planet’s atmosphere. Because photochemical reactions destroy atmospheric methane,...
According to NASA astronomers, the 5,000-plus exoplanets confirmed so far include small, rocky worlds like Earth, gas giants many times larger than Jupiter,...
Physicists have observed the transition from a previously known cubic phase, ice VII, to the newly-discovered intermediate, and tetragonal, phase, ice...
With thousands of discovered exoplanets and new missions that will explore our Solar System, the search for life in the Universe has entered a new era....
Kepler-16b, a rare exoplanet that orbits around two stars, has been detected using the SOPHIE spectrograph at the 1.93-m telescope of the Observatoire...
Using data collected by the Wide Field Camera 3 (WFC3) infrared spectrograph onboard the NASA/ESA Hubble Space Telescope, astronomers have obtained a detailed...
Conventionally, intelligence is seen as a property of individuals. However, it is also known to be a property of collectives. Examples include collective-decision-making...
Using the ULTRACAM instrument on ESO’s 3.5-m New Technology Telescope and NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have observed...
Astronomers using NASA’s Chandra X-ray Observatory have detected five X-ray events from G29-38, which is among the 100 closest white dwarfs. Their results...
Using data from the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations (ESPRESSO) on ESO’s Very Large Telescope (VLT), astronomers...
Astronomers have assembled a catalog of all known Galactic binaries featuring massive disks of gas and dust that are similar to the protoplanetary disks...
A team of professional astronomers and citizen scientists has discovered a giant exoplanet orbiting the G5-type star TOI-2180.
An artist’s impression...
The temperature of a planet’s atmosphere decreases with increasing altitude, unless a shortwave absorber that causes a temperature inversion exists....
