This end-of-life phase of red giant stars is relatively short, and the celestial structures that form around them are rare, so the Tobi Pitcher Nebula is an excellent example of a case study in the evolution of a star

"The effect of gravitational waves on pulsars is very weak and difficult to detect, but we built the credibility of the findings over time as we collected more data," said Caterina Cazziano, NANOGrav team member and senior lecturer at Caltech.

Protoplanets form from clumps of material in disks around newborn stars. When the planet is still forming, that is, when it is still collecting material, it is called a protoplanet. This is only the third protoplanet discovered

From our own cosmic backyard in the Solar System to distant galaxies toward the dawn of time, the NASA/European Space Agency/CSA James Webb Space Telescope has lived up to its promise to reveal the universe like never before in its first year of scientific activity. To celebrate the end of a year A successful first, a new Web image has been released of a small star-forming region in the Rho Ophiuchi cloud complex

The meteorite components enriched in radioactive isotopes formed in the first 100,000 years or so of the formation of the Solar System within the dense filament. The mother filament may have served as a buffer that protected the young sun and helped capture the radioactive isotopes from the supernova shock wave and channel them into the still forming solar system.

An international team of astronomers has announced the discovery of a second planet in the circumbinary system (where planets orbit two suns) of the rare multiple planet BEBOP-1. This planet was discovered using the transit method and was noticed because it passed in front of the brighter of the two stars on different occasions
