The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS) is a novel software architecture utilizing a fast folding algorithm to enable...
On May 24, 2023, as part of the A Sign in Space project, ESA’s ExoMars Trace Gas Orbiter (TGO) will transmit an encoded message to Earth to simulate...
NSF’s Karl G. Jansky Very Large Array (VLA), a powerful radio telescope situated about 80.5 km (50 miles) west of Socorro, New Mexico, is joining the...
Mobile communication towers represent a relatively new but growing contributor to the total radio-leakage associated with planet Earth. In new research,...
The aftermaths of supernovae always produce X-rays, but if the supernova’s blast wave strikes dense surrounding gas, it can produce a particularly large...
Atmospheric ozone and oxygen protect the biosphere of our planet against harmful ultraviolet radiation. In new research, astronomers modeled atmospheres...
Rocky exoplanets orbiting red dwarf (M-dwarf) stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets...
An international team of researchers has detected abundant polyaromatic compounds, organic magnesium compounds, aliphatic branched carboxylic acids, aldehydes,...
Enceladus, the sixth-biggest moon of Saturn, is a top candidate in the search for extraterrestrial life in the Solar System.

Radiation resistance of microbes is a key parameter in considering survivability of microbes over geologic times on the frigid, arid surface of Mars that...
Unidentified aerial phenomena (UAPs), popularly known as UFOs, are of interest for both national security and air safety and NASA’s independent study...
Penn State astronomers Macy Huston and Jason Wright work on the search for extraterrestrial intelligence (SETI). They try to characterize and detect technosignatures...
Methylated gases are made when organisms add a carbon and three hydrogen atoms to an undesirable chemical element. Called methylation, this process can...
The subsurface of Mars during the Noachian period was likely to have been habitable for microorganisms that feed on hydrogen and produce methane, according...
Nitrous oxide (also known as laughing gas) — a product of microbial nitrogen metabolism — is a compelling exoplanet biosignature gas with distinctive...
Enceladus is one of the prime targets in the search for life in our Solar System. Observations made by NASA’s Cassini spacecraft show that this small...
Someday, dozens of tiny swimming robots could whisk through the water beneath the icy shell of Jupiter’s moon Europa or Saturn’s moon Enceladus, looking...
In new research, a team of scientists at the University of Cambridge has tested the ‘life in the Venusian clouds’ hypothesis.
