Martian meteorites deliver a trove of information on Red Planet's structure      (via sciencedaily.com)     Original source 

Mars has a distinct structure in its mantle and crust with discernible reservoirs, and this is known thanks to meteorites that scientists have analyzed. These results are important for understanding not only how Mars formed and evolved, but also for providing precise data that can inform recent NASA missions like Insight and Perseverance and the Mars Sample Return.

Potentially habitable 'exo-Venus' with Earth-like temperature discovered      (via sciencedaily.com)     Original source 

Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The potentially-habitable planet, named Gliese 12 b, orbits its host star every 12.8 days, is comparable in size to Venus -- so slightly smaller than Earth -- and has an estimated surface temperature of 42 C (107 F), which is lower than most of the 5,000-odd exoplanets confirmed so far. That is assuming it has no atmosphere, however, which is the crucial next step to establishing if it is habitable.

Hubble views the dawn of a sun-like star      (via sciencedaily.com)     Original source 

Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that hasn't begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun.
