The Age and High Energy Environment of the Very Young Transiting Exoplanet TOI 1227b: https://arxiv.org/abs/2506.04440 -> NASA's Chandra Finds Baby #Exoplanet is Shrinking: https://chandra.si.edu/press/25_releases/press_071625.html and https://chandra.cfa.harvard.edu/photo/2025/baby/
arXiv.orgThe Age and High Energy Environment of the Very Young Transiting Exoplanet TOI 1227bThe mid-M star TOI~1227 hosts among the youngest known transiting exoplanets. We have conducted new X-ray imaging and optical spectroscopic observations of TOI 1227 aimed at ascertaining its age and the influence of its high-energy radiation on the exoplanet, TOI 1227b. We obtained a definitive X-ray detection of TOI 1227 with Chandra/HRC-I, and measured its Li and H$α$ lines using ANU SSO 2.3 m telescope (WiFeS) spectroscopy. Through spatiokinematic, isochronal, and SED-based modeling, we have constrained the age of TOI 1227 as lying between 5 Myr and 12 Myr, with a best estimate of $\sim$8 Myr. In the context of this age, we model the evolution of the transiting exoplanet TOI 1227b, using the X-ray luminosity derived from Chandra HRC-I imaging. Our modeling suggests that TOI 1227b is currently undergoing rapid atmospheric mass loss at rates on the order of $\sim 10^{12}$ g s$^{-1}$. The modeling demonstrates that the exoplanet's predicted future evolution depends sensitively on assumptions for total and core planet mass, highlighting the importance of follow-up observations of the TOI 1227 star-exoplanet system to enable measurements of both planetary mass and mass-loss rate.

Nature is amazing. On Exoplanet 45346 the Spatio Vine formed into a space elevator. I mean, it’s not technically an elevator, because there are no elevators, but it grows on the planet surface and one single huge strong vine grows up and out into space (Jack and the Beanstalk!!) and once there grows a huge heavy knob of weight so that it stays in orbit. It defies logic, and makes no sense, but it is real.

Universe TodayReviving SETI with High-Energy AstronomyWhat new methods can be developed in the search for extraterrestrial intelligence (SETI)? This is what a recent white paper submitted to the 2025 NASA Decadal Astrobiology Research and Exploration Strategy (DARES) Request for Information (RFI) hopes to address as a pair of researchers from the Breakthrough Listen project and Michigan State University discussed how high-energy astronomy could be used for identifying radio signals from an extraterrestrial technological civilization, also called technosignatures. This study has the potential to help SETI and other organizations develop novel techniques for finding intelligent life beyond Earth.

Astronomers have caught an #exoplanet that seems to be triggering flares of radiation from the #star it orbits.
These tremendous explosions are blasting away the #planet's wispy #atmosphere, causing it to shrink every year.
This is the first-ever evidence of a "planet with a death wish."
Though it was theorized to be possible since the nineties, the flares seen in this research are around 100 times more energetic than expected.

Universe TodayTitan is the Perfect Benchmark for Studying Exoplanet AtmospheresWhile we know of thousands of exoplanets, the science of studying their atmospheres is still in its early days. When astronomers analyze atmospheres, they have to decide which molecules to include in their models, which can bias the results. A new paper proposes that Cassini data on Titan could provide the perfect benchmark, helping to distinguish between different hydrocarbons detected in the atmosphere of an exoplanet.

Universe TodayIn the Search for Earth-like Worlds, We Should Probably Focus on Red DwarfsAccording to the latest studies led by Heidelberg University astronomers, low-mass stars quite often host Earth-like planets. Data collected as part of the CARMENES project were the basis of this finding. By analyzing the data, an international research team succeeded in identifying four new exoplanets and determining their properties.
