Heat to blame for space pebble demise

A team of researchers from the SETI Institute found that heat is responsible for destroying space pebbles, not high-speed collisions. The study used data from NASA's CAMS camera network to determine the age and trajectory of meteor showers, revealing that thermal stresses cause the particles to break apart as they approach the Sun.

JWST captures the end of planet formation

The James Webb Space Telescope has imaged dispersing gas in a young star's disk for the first time. The observations reveal winds driven by stellar photons or magnetic fields, shedding light on the end of planet formation and the evolution of circumstellar disks.

NANOGRAV’s 15-year journey reveals a cosmic hum

The NANOGrav team has detected evidence of gravitational waves at very low frequencies, which they believe may be caused by the merger of supermassive black holes. The signal is thought to be a result of the gravitational wave background produced by these binary systems.

Quest for alien signals in the heart of the Milky Way takes off

A team led by Akshay Suresh is searching for periodic signals in the Milky Way's core, which could be a strategic site for an extraterrestrial beacon. The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS) uses novel methodology to sift through data and identify potential evidence of advanced life forms.

Can ET detect us?

A team of researchers used crowd-sourced data to simulate radio leakage from mobile towers and predict what an alien civilization might detect. The study suggests that some technical civilizations are likely to have more sensitive receiving systems, making the detectability of our mobile systems increase.

TESS Detects Planet in Orbit Around Two Stars

Researchers detected a planet in a 200-day orbit around two stars using TESS data from just one sector over 27 days. The discovery was made possible by observing the planet's transits and eclipses, providing new insights into circumbinary planets.

Dr. Sofia Sheikh awarded National Science Foundation Fellowship for Research & Education at the SETI Institute’s Allen Telescope Array

Dr. Sofia Sheikh has been awarded a Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship to focus on fast radio bursts and develop improved technosignature detection methods. She will also mentor underrepresented students in physics and astronomy, leveraging the Allen Telescope Array's unique qualities.

Is there life on Mars today and where?

Dr. Nathalie Cabrol proposes that modern life on Mars could be more widespread and accessible than previously believed, and that understanding patterns resulting from extreme environmental interactions is key to finding life. She suggests taking the approach of Mars as a biosphere to find signs of microbial habitability.
