![Individual CHEOPS transit observations of V1298 Tau c, d, and b displayed in the left, middle, and right panels, respectively. For each planet, the top row presents the raw (pre-detrended) light curves, the middle row shows the corresponding detrended light curves, and the bottom row shows the residuals from the best-fit model. Unbinned data are shown in sky blue, binned data in dark blue, and the best-fit transit model in magenta. The solid brown lines indicate 50 random samples from the MCMC posterior distribution of the combined transit and systematics model.-- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/CHEOPS.png?resize=1200%2C716&ssl=1)
[astro-ph.EP] The young (10-30 Myr) multi-planet system V1298 Tau presents a unique opportunity to probe the early formation and evolution of young systems.

Detection of Organics in Water Ice by Optical-PhotoThermal Infrared Spectroscopy
[astro-ph.IM] The detection and characterization of organic molecules within water ice is vital for interpreting observations of icy moons and comets. However, organic-ice interactions often distort intrinsic water-ice absorption features, […]

SETI’s Blind Spot: Technological Acceleration And Fleeting Technosignatures
[astro-ph.IM] The search for extraterrestrial intelligence (SETI) has traditionally framed the detection challenge with a focus on the parameter L in the Drake equation – the communicative lifetime of a […]

Contribution of White Dwarf Formation Kicks to the Free-Floating Planet Population
[astro-ph.EP] Free-Floating Planets (FFPs) are a distinct class of exoplanets that do not orbit stars but are nevertheless found to be very common. A variety of formation mechanisms have been […]

Decolonizing Technosignatures: Reimagining Technosignatures Through An Indigenist Lens
[astro-ph.IM] There exist numerous proposals for potential technosignatures that we can search for, but they all tend to be deviations from possible naturally occurring signals. That is, technosignatures tend to […]

Benzene Formation On Interstellar Dust Grain Analogues Via Single-Atom Fe Catalysis
[MRAS] Benzene has been detected across a range of astrophysical environments, though the primary mechanism underpinning its formation has not yet been constrained and the extreme conditions of the interstellar […]
![Geometry of the LTT 3780 planetary system at the time of our radio technosignature observations. The left panel shows the sky-plane (X–Y) view as seen from Earth, while the right panel shows the top-down (X–Z) view of the system. The orbits of planets b (blue) and c (green) are shown relative to the host star (yellow). Our observations from the ATA, mentioned in Table 1 on 5th November 2025, were timed to coincide with a planet–planet occultation (PPO), when planet b passes behind planet c along the line of sight, providing a unique configuration to search for radio technosignatures during mutual planetary alignment.-- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/A-Search-For.png?resize=1200%2C719&ssl=1)

A Search For Narrowband Technosignatures From LTT 3780 With The Allen Telescope Array And The Karl G. Jansky Very Large Array
[astro-ph.IM] The LTT3780 system hosts two known exoplanets-LTT3780b, a rocky super-Earth, and LTT3780c, a temperate sub-Neptune-orbiting a nearby M dwarf on opposite sides of the radius valley. LTT3780c has been […]
