Compared to the rest of the universe, the Earth is very small. Our planet and eight (or maybe nine) others orbit the Sun, which is only one of about 200 billion stars in our galaxy. Our galaxy, the Milky Way, is part of the universe, which includes millions of other galaxies and th...
There is a limit to how big planets can get before crossing into a category of objects called brown dwarfs. A NASA simulation replicates conditions across one of these "failed stars." Want to feel really small? Tour the universe's largest black holes and compare them with distances in the...

In the history of astronomy, new techniques enable new observations of the universe including surprises like the discovery of hot-Jupiters and mini-Neptunes, which have no equivalent in our solar system. The stage is now set to observe the atmospheres of these planets to see which ones have ...
A size comparison of the planets of the TRAPPIST-1 system, lined up in order of increasing distance from their host star. (Image credit: NASA/R. Hurt/T. Pyle) TRAPPIST-1b TRAPPIST-1b, the innermost planet in the TRAPPIST-1 system, is a rocky world that's similar in size to Earth....
(ESSRI) is to quantify the region’s natural and cultural heritage at various scales across land and its flanking oceans, as well as its time-scales ranging from the early Phanerozoic (some 540 million years) to the evolution of the Anthropocene (changes) following the emergence of the first...
(FPAR, LAI, MIR, NIR, Red, NDVI and EVI) were analyzed. Correlations between remote sensing information and field measurements were low, probably due to the extremely large variability found within each paddock for field observations (CV: Around 75%) and much lower when considering satellite ...

this fallibility is outweighed by a classificatory approach founded in deep-seated cognitive processes that govern how humans understand and manage environmental, social, economic and cultural dimensions of their conscious universe by dividing it into parts43. This will facilitate the widespread uptake of...
Trojan asteroids are small bodies orbiting around the L4 or L5 Lagrangian points of a Sun-planet system. Due to their peculiar orbits, they provide key constraints to the Solar System evolution models. Despite numerous dedicated observational efforts in
