  Introduction In the vast expanse of space, few celestial objects tell a story as dramatic as  S5-HVS1 , a star that’s literally breaking free from our galaxy. Discovered in November 2019 by the  Southern Stellar Stream Spectroscopic Survey  (S5), this remarkable star has captured the imagination of astronomers worldwide, as it races through space at the staggering speed of about 1,755 kilometers per second (approximately 6 million kilometers per hour), making it the fastest known star to be escaping the Milky Way. Discovery and Characteristics S5-HVS1 is a main-sequence star, similar to our Sun but about 2.35 times more massive and about twice as hot. Located in the constellation Grus, the star is currently about 29,000 light-years from Earth. What makes it particularly special is its status as a “ hypervelocity star ” – moving so fast that it will eventually escape our galaxy’s gravitational pull entirely. The star was discovered as part of the So...

The search for exoplanets—planets that orbit stars outside our solar system—has yielded many fascinating discoveries. One of the most recent is TOI-1231 b , a unique exoplanet that offers exciting opportunities for scientists to explore atmospheres beyond our solar neighborhood. Discovered in 2021 by NASA’s Transiting Exoplanet Survey Satellite (TESS) and confirmed by additional ground-based observations, TOI-1231 b has quickly become a topic of interest due to its favorable characteristics and potential to offer insights into water-rich planetary systems. Discovery of TOI-1231 b TOI-1231 b was first identified by TESS, a NASA mission designed to survey the brightest stars near the Earth for transiting exoplanets. The star system, TOI-1231, lies about 90 light-years away from Earth in the constellation Vela . Astronomers utilized the transit method to detect TOI-1231 b, observing the regular dimming of the host star as the planet passed in front of it, which allowed them to ...
