NASA report finds no evidence that UFOs are extraterrestrial

Months after a military officer made sensational claims about unexplained objects in the skies, NASA released a report loosely outlining a scientific approach for analyzing UAP reports.
A light, cheap space telescope design would make it possible to put many individual units in space at once. Katie Yung, Daniel Apai /University of Arizona and AllThingsSpace /SketchFab

A new, thin-lensed telescope design could far surpass James Webb – goodbye mirrors, hello diffractive lenses

Space telescopes are limited in size due to the difficulties and cost of getting into orbit. By revamping an old optical technology, researchers are working on a lightweight and thin telescope design.
New research shows that the destructive merging of a star and a planet expels huge amounts of gas, as shown in this artist’s impression. K. Miller/R. Hurt (Caltech/IPAC)

Astronomers just saw a star eat a planet – an astrophysicist on the team explains the first-of-its-kind discovery

Stars begin to expand when they run out of fuel and can become thousands of times larger, consuming any planets in the way. For the first time, astronomers have witnessed one such event.
The TOI-700 star system is home to four planets, including two in its habitable zone that could host liquid water. NASA's Goddard Space Flight Center

Distant star TOI-700 has two potentially habitable planets orbiting it – making it an excellent candidate in the search for life

With more than 5,000 known exoplanets, astronomers are shifting their focus from discovering additional distant worlds to identifying which are good candidates for further study.
